A list of some questions which are not necessarily important, but do puzzle me or where I find existing ‘answers’ to be unsatisfying, categorized by subject (along the lines of Patrick Collison’s list & Alex Guzey & Sam Enright & Scott Alexander; see also my list of project ideas).

There are many big questions about the world we can’t answer and which bother me. Why do we sleep or dream? Why does sexual reproduction exist? Why do humans differ so much, from each other and themselves day to day? Why did it take technological civilization so long to evolve, and why didn’t birds get to intelligence first? Where are all the aliens? Why didn’t China have the Industrial Revolution instead? And how should we have predicted the deep learning revolution?

This page is… not about those. This page is about much smaller, and hopefully more tractable, questions.

Biology

  • Obesity Epidemic: Why do humans, pets, and even lab animals of many species kept in controlled lab conditions on standardized diets appear to be increasingly obese over the 20th century? What could explain all of them simultaneously becoming obese?

  • Alcohol Hormesis: Does moderate alcohol or wine consumption have any health benefits, or not?

  • Boogers: what are dried nasal mucuses, or boogers, made of? What are all their types? Why do they vary so much in color, appearance, structure, and taste? (Why do nose hairs taste so foul?) If they are just dried mucus, why are there big ones deep inside the nose where drying out would seem to be difficult? (And how can solid mucus form so rapidly during illness when airflow is the same or lower?) Are they connected to lymph nodes, or play a role in the immune system? If unrelated to anything immune, why does it change so much during infections, and why do they appear to irritate the throat? Why, if they are being excreted, are they so easy to snort out of one’s nose and one winds up digesting them? What is it that regular excretory mechanisms can’t handle?

    And then what about picking noses or eating boogers? Eating them is almost universal, although taboos make estimates from the one survey WP cites (Jefferson & Thompson 199529ya) unreliable and even more dramatically so in Andrade & Srihari2001’s survey (so how universal?); is this harmful, harmless, or useful in a way similar to the appendix? How many other animals pick their noses? (I’ve never seen a dog or cat wake up and need to blow its nose, or seem to want to pick it—or seen animal boogers at all.)

    We don’t know any of this! After looking at Google Scholar, I have to conclude we know less about boogers than Professor Boogers.

Jeanne Calment

Jeanne Calment holds the verified record for human longevity at ~122.5 years at her death over 22 years ago: Calment is history’s first & only 122 year old; and also the first & only 121 year old; and also the first & only 120 year old. No challenging centenarian has come close to her record, and arithmetically, they will not for years to come: she will have held the record for a minimum of 3 decades, despite countless countervailing factors. Some statistical simulations suggest that Calment-like record gaps are not expected from the distribution of human life expectancies, and as time passes, her record becomes increasingly anomalous.

This truly remarkable longevity raises the question of whether Calment’s longevity is due to the same factors as all other centenarians: did she benefit from some unique factor like genetic mutations, or, as accused in late 2018 of being, is she, in fact, merely a fraud which has fooled previous verification?

Why did Jeanne Calment live so many more years than other centenarians (to 122 years & 164 days), breaking all records and setting a life expectancy record which decades later has not just not been broken, but not even approached? As of 2019-08-17, the oldest person record is held by Kane Tanaka, then age 116 years, 227 days (2,128 days less than Calment), who would have to survive until 2025-06-14 to match Calment; in other words, even if Tanaka turned out to be the first person to break Calment’s record, Calment’s record would have stood from ~1995 to 2025, a remarkable minimum of 30 years.

Graph of time each “oldest person” record holder held record before dying (201311ya Gerontology Research Group data); outlier is Jeanne Calment (her predecessor Florence Knapp died in 198836ya, she died in 199727ya)

Graph of time each “oldest person” record holder held record before dying (201311ya Gerontology Research Group data); outlier is Jeanne Calment (her predecessor Florence Knapp died in 198836ya, she died in 199727ya)

Which is extraordinary considering that she smoked & loved her port wine & chocolate (the secret to longevity‽), medicine has continuously advanced, the global population has increased, life expectancy in general has increased, and the Gompertz curve implies that, with mortality rates approaching 50%, centenarians should die like flies and ever closer in age to each other and not have occasional enormous permanent >3 year gaps between the record setter (Calment) and everyone since then. (I did some Gompertz curve simulations, and Calment-like records do not easily fall out of a Gompertz curve.)

It isn’t necessarily odd that the first well-validated longest-lived person might exceed previous records from sparse poorly-kept datasets by a large margin (much as it is not odd now to see Olympics sports or weather records shattered by large margins1), but it is odd that decades are passing and still no validated centenarians have reached, much less surpassed, Calment’s record. (I had a similar question about the “Dream Market” darknet market, as its longevity was extremely anomalous, especially when one looks at how Type 1 DNM life expectancies appear to be.) Typically, if one looks at record datasets such as the mile run world record progression, as one would expect from order statistics, the ‘gap’ between each successive record holder is smaller and smaller, particularly as the number of ‘competitors’ increases; in running, the number of runners has increased dramatically over time, it has become a major sport/profession with concomitant improvements in training and so on, and this resulted in records being regularly set but by smaller intervals each time, as the extreme of what is humanly possible is approached. Similarly, with longevity, we should see early on large gaps between successive verified record holders as a small number of reasonably-reliably verified super-centenarians from the most industrialized & bureaucratized countries (as opposed to the enormous number of frauds/errors pre-documentation: Young et al 2010/Newman2019) reach the longevity frontier, with gaps regularly shrinking as the rest of the world ‘comes online’ with proper documentation, hundreds of millions of people start competing for the record, improved medicine pushes out the average life expectancy & makes it much more probable to reach an extreme, there is greater scientific & public interest in tracking the extremes, and so on. Instead, what we see is this steady order statistic effect of shrinking record breakers—except for Jeanne Calment, who smashes the record and continues to hold it despite decades of challengers from an exponentially growing population.

The easiest answer is that she is a fake like so many supposed centenarians, but against that, she doesn’t fit the usual fake profiles of existing only on paper like the fraudulent Japanese centenarians; being male; or being in a Third World illiterate country where old age is extremely culturally valued, dates exhibit blatant age heaping, no contemporary paper records exist or their paper trail only began late in life, etc.—she was female, born in Third Republic France in a highly bureaucratic well-organized well-documented literate society which did not especially value extreme old age, was apparently fairly social & not an unknown recluse, was known for longevity in her lifetime (as opposed to afterwards), was vetted by the GRG & others, etc.

On the other hand, Valery Novoselov & Yuri Deigin (1/2) & Nikolay Zak in 2018–2019 accused Calment of having been a fraud, specifically, having died and been replaced by her young daughter Yvonne Calment who supposedly died unexpectedly in 193490ya. The fraud theory originally postulated that the motive for the fraud would be evading the estate taxes which would have been due (on top of the estate taxes paid due to two deaths in the family just 3 years before) & Jeanne Calment’s later annuity (which would’ve been considerably underpriced since she was supposedly much older); aside from the observation that Calment is such an outlier and was remarkable healthy & youthful-looking for her ostensible ages (but more consistent with how old the daughter Yvonne would’ve been), Novoselov notes the suspiciousness of the Calment family archives being destroyed by them, some anomalies in Calment’s passport, oddities in family arrangements, apparent inconsistency of Calment’s recollections & timing of events & photos, facial landmarks like ear features not seeming to match up between young/old photos, and an obscure 200717ya accusation in a French book that a French bureaucrat and/or the insurance company had uncovered the fraud but the French state quietly suppressed the findings because of Calment’s national fame.Robert Young has criticized some of the points, several claims like the estate tax motive have been abandoned by fraud theorists entirely, and there are considerable problems with the fraud theory now. (Presumably DNA testing offers a definitive answer, if the Calment family cooperates, and allows access to extant blood samples.)

Overall, the fraud theory seems highly unlikely to explain the Calment anomaly, but the renewed attention & attempts to vindicate her record have unfortunately also shed little light on what alternative explanations might be true.

Genetics

  • What happened to the famous genome sequencing cost curve around late 201212ya, which halted the exponential price decreases for years, keeping whole-genome sequencing prices high, and thus delaying whole-genome sequencing replacing SNP genotyping in genetics research by up to a decade (with untold medical consequences)? Was it just the Illuminati’s fault & a failure of anti-trust law?

  • Why do humans have such a large mutation load on common genetic variants for harmful traits like schizophrenia?

    Common SNPs make up a large fraction of variance, even for traits which are fitness-affecting and regularly turn up as consistently under negative selection: schizophrenia is a particularly good case of this—highly harmful to fitness & life expectancy, bad wherever found, no apparent offsetting benefits found in either schizophrenics or relatives, clearly under negative selection, only modestly driven by de novo or very recent mutations, not under mutation-selection balance like a trait like intelligence (which is largely fitness-irrelevant and so unsurprisingly has a lot of standing variance) and yet, still exacting a staggering toll of 1% of the population. Why?

    “Culture or technology slow down evolution” doesn’t wash when human fitness differentials are so large and so many people died young or as infants, and how did the many deleterious variants get pushed up to such high frequencies in the first place? Particularly given that my understanding is that almost all interesting SNPs date back many tens of thousands of years, possibly millions, and GWAS analyses indicate that causal variants are largely shared across all human races, undermining demographic accounts like genetic drift.

  • Why does the immune system so often surface as a genetic correlation or tissue enrichment in GWASes for many things not generally believed to be infectious, such as schizophrenia or Alzheimer’s disease?

    Are we missing an enormous range of infections directly causing bad things (or indirectly through autoimmune mechanisms), or is the immune system just sort of like intelligence in being a general health trait?

    • and is this why broad-spectrum antibiotics and early vaccination have such large effects on all-cause & late-life mortality?

  • Cats:

    • Can domestic cats be bred to be healthier & happier under modern conditions of pet life? Or are they neglected, and indeed actively undergoing dysgenics on domestication traits, contributing to vast feline suffering & mortality?

    • Why does catnip response vary so much across countries in domestic cats, and also across feline species, with no apparent phylogenetic or environmental pattern?

      It is so heritable in domestic cats that an evolutionary genetic reason is plausible; but if it’s adaptive, what is it doing when the catnip plant doesn’t exist in the ranges of most tested cat species, and if it’s evolutionary fitness-neutral why can so many closely-phylogenetically-related species respond to it in different ways?

    • Hybrids: is it just me or are domestic cats weirdly hybdridizable for a mammal?

      It seems like you can cross them with just about any other Felidae aside from the big cats, despite speciations going back >5mya.

  • Variance components outside genetics:

    Where else besides genetics can we use behavioral genetics’s workhorse of variance components analysis to nail down the net contribution of entire classes of effects rather than the usual (and usually futile) approach of attempting to exactly estimate one or a handful of said effects? In many areas, researchers focus on futile efforts to estimate the exact contribution of each of a myriad of factors, despite lacking anywhere near enough data, and the resulting null results are uninterpretable: did those factors not matter, or were they just woefully statistically-underpowered?

Psychology

  • What is “personal productivity” and why does it vary from day to day so much (eg. Weinberger et al 2018)? And why does it not seem to correlate with environmental variables like weather or sleep quality (at least using my non-sleep-deprived logs), nor manifest as the usual kind of latent variable in my factor analyses? Is it something much weirder than the usual kind of latent variable, like a set of zero-sum measurements drawing on a generic pool of ‘energy’ or ‘mana’?

  • Does listening to music while working serve as a distraction, or motivation?

  • Nicotine alternatives or analogues: there seem to be none, but why not?

    Nicotine is one of the best stimulants on the market: legal, cheap, effective, relatively safe, with a half-life less than 6 hours. It also affects one of the most important and well-studied receptors. And because of its evolution as an insect defense, there are countless insecticides on the market that people have been exposed to and could have reported interesting psychoactive effects (which is how most of the good drugs are found).2 Why are there no attempts to develop analogues or replacements for nicotine which improve on it eg. by making it somewhat longer-lasting or less blood-pressure-raising, when there are so many variants on other stimulants like amphetamines or modafinil or caffeine? Indeed, why not just use nicotine’s primary metabolite, cotinine?

    (The one exception I currently know of is a biotech company, Targacept, which attempted to develop nicotinic receptor drugs for ADHD/depression/Alzheimer’s/bladder problems such as variants on mecamylamine, but their drugs failed in clinical trials and they were acquired in 2015. Given the highly risky nature of drug development, it’s unclear how much to infer from their failure about whether better nicotines exist—Alzheimer’s disease is where exciting drugs go to die, and a useful stimulant may not have so large a benefit as to be compelling in trials for ADHD or depression—I doubt caffeine or modafinil could justify large Phase III trials on the basis of their effects on ADHD!)

  • Does modafinil build tolerance, or not? The academic literature’s consistent claim that it doesn’t completely contradicts the equally consistent anecdotes from most modafinil users that it does, and seems a priori implausible.

  • Why does writing in the morning (anecdotally so far) seem to be so effective for writers, even ones who are not morning persons? While programmers, which seems like a similar occupation, are invariably owls?

  • Richard Feynman made a famous critique of poor experimental controls in psychology exemplified by flaws/side-channels in mouse experiments, as demonstrated by a “Mr Young”; but who was Mr. Young & what research was it?. It’s not like Feynman to make things up, but all attempts to find the original research in question have failed and it’s unclear who Young was.

    Mostly solved by the discovery of Maier, Curtis, Shepard & the University of Michigan.

  • In 193589ya, the psychologist David Wechsler compiled a dataset of human performance on everything from running to punch-card processing, where absolute/cardinal measurements were possible (rather than ordinal ones like IQ) and observed that the absolute range of human capabilities is ~2–3× (best/worst out of 10001,024ya healthy people—which is consistent with general low levels of competence): The Range of Human Capacities. Looking through the rare citations of it, his generalization does not appear to have been meaningfully gainsaid since.

    Since running across this in, I believe, Epstein2013’s The Sports Gene, I have felt like this is a neglected observation that should tell us something important about human biology or genetics or intelligence—why only 3×? and so consistently 2–3×?—but nothing has ever gelled.

  • Dissociative traits:

    • How common are, and what is going on psychologically, in the occasional eruption of large shared3 fantasy worlds (“paracosms”) among children & adolescents?

      There are many cases of a (typically pubescent, typically female, similar to mass psychogenic illness) child or adolescent building such an intense fantasy-world that they wind up sucking in & convincing family/friends/classmates. J. R. R. Tolkien’s worldbuilding may not have started early enough to be an example of this as his cousins & his worldbuilding was almost exclusively linguistic, but the Brontë sisters are a clearcut famous case. They typically go unreported except in extreme cases (such as the Parker-Hulme murder case4, the Trianon Moberly-Jourdain incident (Castle1991, [Archibald2023](https://publicdomainreview.org/collection/an-adventure “‘In the Mind of Marie: A Haunting Encounter in the Gardens of Versailles (1913111ya)’, Sasha Archibald 2023-06-06”“)), possibly June and Jennifer Gibbons, the Slender Man stabbing, the Manchester stabbing), often reported only in passing5, as background material6 or via anecdotes—I have been told of 4 cases (3 from acquaintances, one indirectly), all of which follow the same pattern of a young female teenager building up a fantasy world (with heavy input from dreams) and engrossing friends/classmates (with the exception of a male twin pair, see also cryptophasia).

      But there doesn’t seem to be any recognized name for this pattern (“chuunibyou syndrome”? “Tlön syndrome”? “Terabithia complex”? folie à plusieurs) or discussion of epidemiology. Is it an expansion of maladaptive daydreaming? Is prevalence underestimated due to childhood amnesia (similar to how imaginary friends are not anomalous but may be had by the majority of children, though they forget as adults)? Being so extremely private & introverted & embarassing by nature, how many such shared paracosms never get mentioned, or hide under guises like D&D campaigns, fantasy (fan)fiction writing, micronations, occult hobbies like astral projection/“shifting” (likely actually lucid dreaming)? Are the dynamics the same as proto-religions (the ways in which the paracosms are extended, particularly by dreaming, bear a great deal of resemblance to the origins of religions like Christianity)?

    • Speaking of dreams, a curious Internet subculture is tulpas: using imagination and meditative practices to envision & create an imaginary friend so strongly that one can hallucinate them & perceive them as acting autonomously (typically done to create a friend or advisor); one ‘tulpamancer’ I know remarked that success seemed to correlate with an above-average ability to engage in lucid dreaming or to be hypnotized, suggesting that tulpamancers are unusually able to dissociate. (Would daydreaming, or maladaptive daydreaming, be also more common?)

      This immediately reminded me of Luhrmann’s 201212ya When God Talks Back, which documents evangelical Christian and other cult practices which enable the believer to actually hear God’s voice and ‘befriend’ Jesus through a variety of auto-suggestive meditative practices. Are these believers engaged in literally the same psychological task as tulpamancers, and the practices effectively make a Jesus tulpa? (What would brain imaging scans show the neurocorrelates of hearing a tulpa vs hearing God, one wonders…)

  • What is with red color perception being so important that red is the first named color in pretty much every culture studied & the red/black contrast a favorite of designers for millennia, when humans actually see green (also a vastly more common color) most easily?

  • CO2 & cognition: what effect does CO2 actually have on human cognition (especially intelligence) at concentrations considered neglible, and why do a few researchers report far higher effect sizes than the rest of a large literature?

  • Why are fire & ocean waves (and forests to a lesser extent) so hypnotic?

    Are they the Shepard tones of vision—the creation of the illusion of endless progression/change by having so many small overlapping elements individually cycling that one gets fooled into seeing the fire ever burning or the waves ever coming in?

Psychiatry

  • What is the “afterglow effect” (1/2, /r/hangovereffect) where some people with ADHD-like symptoms report abrupt temporary relief during the hangover the next morning after consuming large amounts of alcohol & sleeping? (Anything to do with methanol? Or uric acid?)

  • Why does sleep deprivation briefly treat depression (Boland et al 2017, Daghlas et al 2021)? This makes no sense under the usual theories of depression like chronic inflammation or risk-aversion or too-little brain plasticity, but the experimental effect appears well-established. (And how does ketamine work anyway?)

  • If child abuse and emotional neglect is so harmful and there is nothing more to it than that, why does it appear in the biographies of so many people who achieve greatness, often middle/upper-class? It may do this by increasing variance (offsetting, for the top end, decreases in mean outcomes), but how—why would any subset of children have better outcomes for any reason because of abuse/neglect? If it increases motivation and creates a ‘rage for mastery’, is there any way to capture the benefits without being evil?

  • What and why and when are “furries”?

    One of the core demographics of Patreon, by amount spent, is the “furries” subculture commissioning artwork & other things catering to their fetishes; furries are also well-represented on image boorus, providing some of the largest & best tagged databases (even larger than Danbooru), and historically were (along with fanfiction) one of the most extreme userbases of del.icio.us; further, furry conventions are surprisingly robust, catering, among other things, to fursuit makers selling extremely expensive (and often custom) fursuits; even further, furries appear to be extremely overrepresented among tech workers (an autism spectrum connection?). I’ve kept noticing furries within a few degrees of me (an artist acquaintance does SFW furry commissions, an online acquaintance learned English thanks to furries, another told me of furry IRC channels for just techies coordinating projects & trips & donations, yet another told me that it was not uncommon to see furries suited up in datacenters, the Damore lawsuit materials mention furry groups in Google along with ‘otherkin7, and so on), public examples of furries like SonicFox are increasingly common, and I’ve begun to wonder. In general, furries seem to be bizarrely rich, well-connected, and capable—the Quakers of fetishes. (Does the underserving of furries foster self-reliance & skill-building—no one is going to make any fursuits or software for them if they don’t—and an early migration to the Internet back when that forced community members to develop considerable technical skills, positioning them for the explosion of the Internet sector?)

    Is this true, why are furries so rich and well-funded, and why tech, specifically? Why so many so recently, not just offline, but in their safe spaces online? When did ‘furries’ become a thing? I have yet to run into a clear reference to them before the 1970s–1980s, typically vaguely ascribed to convention dynamics, and they may primarily postdate even that (see WP & WikiFur & 2 Reddit discussions).

    But it is not as if anthropomorphization or novels featuring animals or funny artwork of animals were only invented in 1970s or 198044ya; for example, the Playboy bunnies were 1960s, the Batman character Catwoman was 194084ya (just barely preceding Cat People), Disney had centered around anthropomorphization since 192896ya, Japanese catgirls were 1920s (although one could trace it back to Cordwainer Smith publishing in 1960s, assuming one didn’t tap into the general eroticization of cats which arguably goes back all the way to the Egyptian use of ‘miw’ for cats and then girls, and the fertility cat-goddess Bastet, serving along the way as a symbol of promiscuity, and Egyptian cartoons from thousands of years ago comically depict cats & rats, see Malek’s The Cat in Ancient Egypt) and probably one could trace many examples much further back than 197054ya. So why did it come into existence then, rather than long before, and what has made it so common? Why does it follow the apparent demographic patterns it does?

    If it indeed did arise in the 1970s due to some generic combination of economic development, popularity of comic books, technology, or cultural shifts, did many other paraphilias arise in the same time period? Indeed, where do paraphilias in general come from?

  • Does low trace levels of lithium in drinking water (which would be quite cheap to increase) reduce violence/crime/suicide/mental illness/death, or not?

  • How concerned should we be about anesthesia awareness (WP)?

  • How concerned should we be about concussions/head-injuries/“traumatic brain injuries” (TBIs)? Are we crazy for not wearing walking/driving helmets?

  • Why do I persistently get problems in self-experiments using metals like potassium & magnesium?

  • What is the psychology of “collecting” and “collectibles”? Particularly from an evolutionary psychology perspective. Can it possibly serve any function, or what continuum is it a maladaptive extreme of?

  • Did Calhoun’s Mouse Utopia exist as described or replicate? One of the most famous animal experiments ever run, with dramatic political implications, Mouse Utopia turns out to be bizarrely under-documented with many tell-tale signs of the Replication Crisis: Calhoun published little, his publications lacked many details and seem to imply that the famous Mouse Utopia was merely one of many experiments (most of which did not deliver similar results), it did not replicate when others early on attempted it, and there are other possible explanations Calhoun did not have any interest in investigating & simply dismissed out of hand.

Fetish Economics

How does fetish economics work in general? Anecdotally, creators in fetishes (eg. feet, furry, futanari) report it being highly lucrative despite them not enjoying it themselves—indeed, it’s lucrative because they don’t enjoy it and only do it for the money, requiring extraordinary premiums.

The imbalance is long-standing, and common to many fetishes. An absolute lack of supply is clearly not the reason, and a “risk premium” based on stigma appears inadequate for an imbalance that looks more like excess demand rather than extreme scarcity of supply. I suggest that fetishes do have high demand, as an inherent property of being extreme differences in preferences, and this uses up all fellow-fetish creators and then runs up into very high reservation prices from outsider creators, thereby resulting in unusual prices at the margin.

“This really isn’t my thing / But I really like money” (photo by Jennifer Xiao)

Furry art has a reputation for being easy money if you can tolerate the work, and more than one creator has anonymously reported that the commissions revolt them but there’s no way to make thousands of dollars a month as an illustrator as easily; I have heard about at least 2 computer game developers who marvel at the amount of money they can make off foot or other fetish games (often technically trivial, being visual novel-style games using free software like Ren’Py, requiring mostly artwork & writing), easily up to $4,000/month. (In one of those cases, they wrote a fic to mock the fetish, but the positive reactions—accompanied by demands of “take my money!”—convinced them to start making & selling actual games.) These disparities do not seem to be new or reflect trendy topics; there appear to be large increases in commissioned artwork, for example, but driven by innovations in market mechanisms & supply-side factors (eg. the rise of Patreon, or 2-sided commission markets like Skeb.jp—which benefits from the huge progress in machine translation, and easier international payments). The demand was always there, but could not be easily tapped. A related question is BDSM; one is always hearing about female doms (but not subs) making extremely large amounts of money, much more than regular sex workers—it makes sense if there are more female subs than female doms, and vice versa fewer male subs than male doms, but then why the extreme premiums when it seems balanced?

This sort of massive premium is a little odd on the face of it: why is supply & demand so imbalanced, and supply so inelastic? If a fetish is X% of the population, one would expect X% of programmers, artists, etc, to share that fetish. If there are a lot of people who want foot-based games, then one would expect there to be a smaller but still large number of people willing to supply such games, and the problem solves itself; if there are not many fetishists, they may go wanting, but there also won’t be all that much money in catering to them either, it would simply be an odd niche that perhaps some creators happen to occupy, but not strikingly lucrative.

While we don’t know much about why paraphilias change over time or why a paraphilia may develop in the people it develops in, we definitely don’t know any reason to expect a fetish to be underrepresented in artists/programmers and overrepresented elsewhere. There probably are differences (simply on “everything is correlated” grounds), but we don’t know which (in the 3 Fs mentioned, artists/programmers do not seem underrepresented, if anything, perhaps the opposite), nor do we know that they are so large that they could drive these premiums.

A lack of generic supply is also a questionable explanation. “Those lucky vanilla heterosexual types have all the porn in the world and can go their entire lives without spending a cent, but you drew the short end of the stick.” Sure, if there were some dire shortage in absolute terms, like only a dozen pictures across the Internet of your fetish, you may find it worthwhile to pay for more yourself. But this is hard to reconcile with the facts. Can we really say that there is a dire shortage of each fetish when image boorus or porn video sites devoted to each type, like e621, can collect millions of images/videos within a few years?8 (Danbooru, for example, adds >0.5m images/year—and it has a reputation for being selective!) ≪X%, accumulated over time worldwide, can still be vastly more than any individual can reasonably consume in a lifetime. None of these fetishes seems likely to have a true shortage, per individual, of spank material; if they feel themselves supply-constrained and having difficulty buying more, there must be more going on.

One possibility is that the premium is a risk premium, compensating for participating in a fetish regardless of how much one enjoys it. Perhaps even talented foot fetish artists are reluctant to do more than play footsie with that fandom, because it might get out and handicap them socially or financially? It is difficult to port a reputation in only one direction: if the Z fetishists, who are X% but are frustrated at getting ≪X% of total supply, know an artist offering commissions is mainstream artist Y, and want Y’s services because they can see Y does great work, and Y like that fetish and so doesn’t need to demand a premium due to the greater intrinsic costs, Y may still be worried about “Y does fetish Z” getting out and either demand a big premium or set up under brandnew pseudonym A (if they do at all—any good artist will worry about their art style being identified; ex ungue leonem), constraining output due to lack of reputation.

There is a definite hierarchy of how stigmatized fetishes are, and this seems like a highly plausible hypothesis. Feet aren’t too bad; models in interviews sound kinda nonchalant about it, taking an “it’s weird and I don’t really get it, but it sure pays the rent” perspective. Futanari is definitely weirder, and furries weirder still, having long been the butt of Internet status hierarchies. And it does seem like the supply problem gets more acute as you go down, which is consistent with the risk premium hypothesis. But is this a big enough effect to drive such wacky price dynamics? Are futanari or foot visual novels so discriminated against that all the creators flee and yet, one can pick up thousands of dollars by simply rolling their eyes and ignoring these stigmas with no visible consequence? (And if we believe most creators have fled, where do all those millions of images and videos and games come from? Just how many would there be if all of the creators stayed‽)

If you don’t find that adequate, what else could be going on? Since we are dealing with deviant individuals here (in both senses), we might look for generic distribution effects—in particular, our old friend, tails. (Of distributions.) We might argue a priori about X% parity and proportional representation among each fetish or preference, which is a safe argument, but that doesn’t mean that the total distributions of those fetishes need look anything like each other. It would be bizarre to expect every sexual preference or fetish to be distributed equally, when we already know counterexamples like lesbianism vs male homosexuality, and the mere fact of differing stigmas would be expected to create differences.

Imagine a normal distribution of “willingness to pay for custom porn of Z”. For regular porn, it is a wide distribution centered around the population mean. But when it comes to, say, feet, there may be some willingness to pay among non-fetishists for images that happen to include feet (perhaps as part of some more general pose or scene), but the foot fetishists will be their own distribution with a mean shifted far to the right (and probably much narrower, with a smaller standard deviation)—many are still unwilling or unable to pay, but many will be, and because of tail effects, there will be, counterintuitively, multiplicatively many more.

This is another way of saying that fetishes tend to be intense. Such preferences, arising from whatever source, seem to be fairly discrete. There are not going to be terribly many people who feel lukewarm about a fetish and find it sorta-hot-but-ok-maybe-not-really. This correlates with the stigma: the further away a fetish is, the less everyone else can understand it. The intensity is where the disparity in demand comes from: the fetish may have their fair share X% of artists, but they are an intense minority which demands ≫X%. This demand eats up the X% instantly, and goes hungrily looking for more. And, since the fetish is intense and the remaining supply all tend to feel intensely the other way about the fetish (being all the way in the other distributions many standard deviations away from Z), suddenly, at the margin, the clearing price skyrockets. (As an extreme example, consider guro or crush.) Creating X−2% or X−1% of supply is relatively easy (even, free); creating X% is easy; but creating X+1%, that requires pulling in a lot of creators from elsewhere and that is increasingly and eventually extremely expensive. Personal preferences are rigid and come from mysterious unknown causes, so both supply and demand here are locked in place indefinitely, without the typical long-run effect where high demand elicits permanent supply increases. (There are comparable examples like science funding: for all that scientists complain about lack of funding, they are individually locked into their particular research topic to the extent that the NIH has to increase grants by 40% to pull in novel researchers!) To the extent that risk premium reduces supply, this merely exacerbates the prices.

The tail effect model predicts that this situation will be stable long-term because it is rooted in human psychology. It further predicts that the premium will be due more to the personal level of disgust experienced by outsider artists than to fetish popularity or risk or stigma because the risk premium is confounded: the stigma will predict the premium, but not cause it, because both are caused by the same thing. Exogenously reducing the social stigma (without people changing their gut response) or reducing it in other ways like providing more anonymous ways to work may ease the supply situation a bit, but will not lead to any major changes in the market. (In comparison, improving mechanisms like market websites or assurance contracts, or automating artwork using neural networks, might well have large effects as it lets the demand more efficiently extract supply. Neural networks don’t care.)

Anti-Psychedelics

Psychedelics famously dissolve personal identity and make you ‘one with everything’. If there are so many drugs which can do that, where are the drugs which do the opposite, strengthening identity and making you one with nothing?

There are a few candidates like MDMA or ketamine/DXM which may do something like that, but not many and not convincingly.

This may show that psychedelics’ effect on identity is less interesting than it looks: it is easier to destroy than to create, and this may be why so many psychedelics can have such similar effects in dissolving but never strengthening identity.

Psychedelics and hallucinogens induce a bewildering range of sometimes extraordinary effects; but if there’s any common trait to trip reports & descriptions across hundreds of different psychedelics, it’s that they tend to ‘weaken boundaries’. One loses one’s ordinary sense of being a discrete, separate person, identifiable & distinguished from other people, and one begins to feel as one with the people nearby, humanity, earth, God(s), universe, the multiverse, or even grander & more ineffable unities.

Anti-psychedelics to make you soberer than sober. So far so good. But after reading enough Erowid trip reports, I began to wonder: if some drugs can weaken identity boundaries, then shouldn’t there be some drugs which strengthen it? (A drug which makes you not drunk on hallucination, but ‘knurd’, soberer than sober, as Terry Pratchett put it.) And if there are many fewer such drugs than psychedelics, perhaps even zero, then why? (We can imagine an ‘inverse’ or ‘anti-Buddhism’9—whose scripture is doubtless Ayn Rand—and which preaches the gospel of greed, focusing on strengthening one’s personal identity, cultivating appetites and preferences, and developing agency; so why not imagine an ‘anti-psychedelic’?) If psychedelics like the ones Shulgin reports can have so many oddball effects like ‘make everything sound like it’s at a great distance’ (I vaguely recall one of Shulgin’s reports mentioning), then surely some of them can reverse their usual dissolving effect. Why can’t I feel, with the same absolute certainty that I feel ‘all is one’, that I am a unique snowflake utterly unlike any other human being or organism? Why is there no drug that dehumanizes other humans, turning them into clockwork mechanisms and zombies and sheeple, while I’m the only real person? A drug which refines identity down to feeling separate parts, memes, cells, biomes, selfish-genes, molecules, atoms…

…Or for meeting mitochondrial, not machine, elves. Or, if that doesn’t really make sense (maybe one already conceives of oneself as maximally separate, in the way the integer 1 is already non-identical to the integer 2 and can’t be made ‘more non-identical’), why can’t any ‘unification’ happen internally? Why does the psychedelic experience always seem to be external, in unifying me with things ‘outside my skin’, as it were? Why, on DMT, does one travel to another universe to meet the machine elves, instead of traveling down inside a skin cell to meet the mitochondria elves, or pause for a chat with the jumping transposons on chromosome 13? Why don’t I meet a Parliament of Organs inside, where my kidneys bicker while my liver sighs? Or to take a more cognitive tack, is there a drug which would let me step back and observe the wheels of my mind go around—see the working memory distinct from short-term memory, the long-term memory pulling up & rewriting memories, where the inner monologue comes from, cruder associative cognition acting before slow serial processes binding many regions in a shared computation…? All of these seem logically & psychologically possible, and not even that strange compared to many drug effects or psychiatric conditions.

Anti-psychedelic candidates:

  1. Stimulants If we ask what the ‘opposite’ of psychedelics is, most people would suggest stimulants: cocaine, caffeine, nicotine, amphetamines, modafinil, etc.

    Are they ‘anti-psychedelics’ in this sense of identity-strengthening? I’ve never taken cocaine, but the others don’t give me the feeling of freezing the way psychedelics give me the feeling of melting. And perhaps more importantly, even if we claim they do, they seem far weaker. Most caffeine, nicotine10, or modafinil use comes nowhere near the effect of quite ordinary psychedelic trips; one has to use extraordinary doses, potentially risking lethal overdoses, to start seeing psychedelic-level effects.

    Cocaine and amphetamines (and dopaminergic stimulants in general) can cause a degree of psychosis, but it takes a lot of sustained abuse to begin psychedelic-tier effects like seeing ‘the shadow people’ hallucinations under amphetamines. (And even the most extreme hospitalization-level amphetamine psychosis don’t seem to reach the peaks & depths of a single 5-MeO-DMT trip casually will.)

    Psychedelics are just really amazingly powerful. If these are the best we can find for ‘anti-psychedelics’, then we still have a puzzle.

  2. Dissociatives: Another possibility is more sedative or dissociative drugs like DXM or ketamine.

    I am not personally familiar with DXM nor have I read much about it, but I am skeptical that the effects of dissociation match here. Inducing depersonalization & derealization so you feel like you & the world no longer exist is an interesting effect (however unpleasant), but that sounds more identity-annihilating than strengthening. Likewise, to the extent DXM produces frightening schizophrenia-like intrusive thoughts & inner voices which come involuntarily from nowhere, that’s it breaking down your identity, not strengthening it—you should know where they come from and be able to control or at least understand them.

  3. MDMA is an interesting candidate.

    While I associate it mostly with cuddle-puddle and therapy and loss of ability to perceive threats/danger, which looks like ‘dissolving’ to me, I am told that when people rolling on MDMA introspect about themselves, they sometimes spontaneously develop an Internal Family Systems Model-like internal dialogue with reified parts of their mind, talking to sub-personalities or personifications. If true, MDMA would seem to count as an ‘anti-psychedelic’ at least sometimes, and would be an interesting psychiatric therapy approach. (MAPS has apparently mentioned this possibility.)

  4. Salvia divinorum: mentioned to me as sometimes having experiences of one’s mind dividing into multiple co-occurring parts, and sounding like a candidate.

Few candidates. Overall, while there are some good candidates, there does not appear to be any large pool of well-known drugs which have astonishing anti-psychedelic effects on par with psychedelics. Even if a few like MDMA or Salvia can do it, this is strikingly rare compared to regular psychedelics, where it seems like hundreds of RCs come onto the market each decade.

Breaking, not making. Why this imbalance? The most obvious answer is that “it is easier to destroy than to create”. A lack of boundaries is the default, and identity is constructed with difficulty. Both a theory of mind and a sense of self are great cognitive achievements, and easily undone.

Shattering the network. On a neurological level, simply weakening global connectivity and the intricate coordination between brain regions will reliably produce dissolution. But it is much more difficult to improve the dynamic coordination of brain regions, making the global workspace more efficient and integrated. After a certain level of disconnection (induced by psychedelics or anesthesia) breaking the unified brain down into modules, one is unconscious, affected regions are no longer able to store verbalizable information in long-term memory for later reporting, or the cut-off regions are so autonomous that they become a blind-spot or agnosia (like in split-brain syndrome11).

Brains are hard to fix. In this sense, ordinary consciousness is in fact as about unified as is possible. There are no more brain regions which can be usefully integrated, and the existing regions are coordinated as skillfully as possible given one’s particular genetic endowment, environment, and cognitive development. Some stimulants tweaking the brain usefully, or some oddball side effects which create subjective states faking it, is as good as you can expect. It’s hard to improve a generic human brain, like it’s hard to improve every car’s mileage by dumping random chemicals into their gas tanks without even knowing what model or if they are a diesel engine instead.

Sociology

  • Face-to-face meetings, even brief ones, appear to cement personal connections of trust and liking to an extent not achieved by even years of more mediated contact like phone calls or Internet text discussions / emails / chat; this appears to be true in almost every context, even ones like British inventors meeting their heroes (in a different field) just once, with large step functions in connections despite the apparent near-zero marginal information conveyed by a brief physical visit after long-term interactions & track records. (This might be related to “Bloom’s 2 sigma problem12.)

    Is there something qualitatively different about personal meetings, and if so, where is it? Is it eye contact? Body language? (It’s probably not pheromones.)13 Is it mere physical proximity and a certain “inability to suspend disbelief” about a technologically mediated person? Can large wall-sized TV screens for teleconferencing achieve the same effects as regular conferencing? Or do they need to be 3D? What about VR headsets, are they adequate already with avatars and hand-tracking gestural control, or do they require eye tracking, or facial expression mapping? How much is enough for true “responsiveness”?

  • Given the crucial role of trust and shared interests in success stories like Xerox PARC or the Apollo Project or creative collaborations in general, why are there so few extremely successful pairs of identical twins, and relatively few examples of duos like the Winklevoss twins Cameron/Tyler Winklevoss? Even broadening further to siblings, there are not that many–famous families like the Kardashians, individually famous people but not many famous collaborations like the Chudnovsky brothers (profiles: 1, 2), or Hollywood’s Coen brothers & Wachowski brothers. The reader will struggle to think of more than a handful, or even any other examples (the Bee Gees, over half a century ago? some random football or baseball people?).

    As identical twins are ~0.5% of the population (eg. of the USA’s >332m people ~2021, there should be >830,000 twin-or-higher sets14), their mental & physical health differences are only slightly different from singletons, and a large fraction of the population has at least one sibling, and the benefits seems so clear (thus they should lead to not merely being common but enormously overrepresented among elites by the usual tail/order statistic effects)—where are they?

    Identical twins should have collaborative superpowers, between shared genetics & upbringing, in their much-envied abilities to completely implicitly trust each other, predict what the other would agree to or be interested in, and so on (collaboration taken to the point of identical twins reportedly sometimes developing a private language or creole in childhood); siblings should also have similar (but much smaller) advantages in collaboration compared to working with strangers. Is the answer something relatively boring like “the slight health/IQ penalty for being an identical twin plus the low base-rate of identical twins plus their remaining variance meaning that one of the pair won’t clear various thresholds means you wouldn’t expect to see many and this is consistent with what we see” or is there some deeper lesson here about greatness/creativity/risk-taking? (The most amusing explanation, of course, would be “most successful people are in fact secretly identical twins”.)

    The boring answer of remaining-variance suggests this might be another case of log-normal pipeline/‘emergenesis’-like multiplicative rather than additive dynamics meaning that a little is just too little. Yes, identical twins are indeed quite similar on some traits like height or IQ, and so you do expect roughly proportional amounts of twin pairs which will be highly talented; but talent is merely the starting point.

    All models of elite accomplishment (as opposed to mere possession of talent) place great stress on the roles of interest & motivation (in addition to other factors like sheer luck). Someone who isn’t particularly driven to accomplish anything, probably won’t, and punching the clock 9-to-5 will rarely cut the mustard, particularly in any kind of competitive field. Such motivation is itself pretty weird and aberrant; you have to be a strange person to have a ‘rage to mastery’ for many things, like genuinely wanting to devote your life to hitting a small fuzzy ball around a concrete parking lot, or play a game meant for children for the rest of your life as your greatest achievement. One can argue that since motivations/interests/hobbies/leisure-pursuits/entertainment-references are all themselves heritable, but this overlooks that the heritability tends to drop the specific the trait you measure: interest in “literature” can be expected to be larger than interest in “Ancient Greek epic poetry”; there is also a base-rate problem, because it is common to be ‘interested in literature’ but the more you break it down, the tinier the base rate gets, and it is not helpful for identical twins to go from, say, a 0.01% probability of being obsessed with Greek poetry to a 0.5% probability, even if that corresponds to a rather large effect parameterized in odds or R2… There will still be basically zero pairs of identical twins both obsessed with the same thing. And if they are not obsessed with almost identical topics, there will be little scope for any genuine long-term collaboration. Even if they both go into the same field like mathematics, but one goes into probability theory and the other goes into, say, transfinite ordinal research, regardless of whatever ‘collaborative superpowers’ they may have, there just won’t be much to talk about professionally rather than at the dinner table, and their colleagues in that area will still be the most useful to seriously work with.

    So in this model, we’d expect to see identical twins with similar-ish professional interests, yet, not so similar that they remain a single unit. That does strike me as consistent with what I see: it’s not that unusual for biographies to mention an accomplished sibling or identical twin (“famed physicist John Smith’s daughter Kate is a world-renowned marine biologist and his son a violinist…”), and there are many eminent families (can’t throw a stone without hitting one), but as predicted, it’s still relatively unusual for parent/child or sibling pairs to engage in the same work (like the Thompsons on acoustics, the Bachs on Baroque music, or the Bernouillis on probability & mechanics).

  • Small Groups: Why did it take until the late 20th century for Brazilian Jiu-Jitsu to develop and the Gracie family crush almost all other unarmed martial arts at the start of MMA (or perhaps Xu Xiaodong), when humans have engaged in unarmed combat for millions of years and every major country has long lineages of specialized competitive martial arts and tremendous incentive to find martial arts which worked and quick feedback loops? (Regardless of whether the Gracies’ early achievements were overhyped, it still seems like MMA had a enormous impact on the practice of traditional martial arts and that MMA continues to resemble BJJ much more than most things pre-MMA.)

  • Is physical beauty relative or absolute and if the latter, is it objectively increasing over time? Photographs of exceptionally beautiful women from the 1800s or early 1900s, or nude/erotic paintings from before then, strike most people are being drab and unattractive. Given the stability and cross-cultural consistency of beauty ratings, it seems unlikely that it is merely a matter of shifting norms or preferences or fashion but represents a real ‘absolute’ gain in attractiveness.

    What is going on? Has cosmetics and hairdressing really advanced that much or should we look at explanations like vastly superior vaccines, elimination of childhood disease, superior nutrition, elimination of hard (especially agricultural) labor15, poverty etc? (Large gains in means would not be unprecedented: when we look at photos of children or people from those time periods, one common observation is how short, scrawny, and stunted they look—and indeed, as an objective fact about an accurately-measured cardinal measure with absolute values, they were short & scrawny, and things really have improved that much.) If physical beauty is not zero-sum, how far can it go? Can we expect weird effects akin to ‘the tails come apart’ or the Spearman effect where after sufficient baseline gains, ‘beauty’ starts to diverge in orthogonal directions/specialized types? Or might, like the Flynn effect and height, we already be experiencing a reversal due to the obesity crisis or other factors like mutation load and we have already seen ‘Peak Beauty’ (at least for the average person, of course CGI/growing populations/cosmetic tech implies that models & actors will continue their evolution into superstimuli)?

AI

  • What, algorithmically, are mathematicians doing when they do math which explains how their proofs can usually be wrong but their results usually right?

    Is it equivalent to a kind of tree search like MCTS or something else? They wouldn’t seem to be doing a literal tree search because then there would almost never be mistakes in the proof (as the built-up tree of theorems only explores valid inferential steps), but if they’re not, then how are they handling ‘logical uncertainty’? Are they doing something like MCTS’s random playouts where lemmas are not proven but simply heuristically given a truth value to shortcut exploration and the heuristic is accurate enough to usually guess correctly and this is why the proofs are wrong but the results are right?

  • NN overparameterization: We can train large deep slow neural networks to human-level performance on many tasks, and we can then train small shallow fast versions of those NNs to save energy/enable mobile deployment, so why can’t we train small shallow fast NNs in the first place? And what would happen if we did figure it out?

  • how can we detect emergent steganography & deception in large neural network models?

Technology

  • Who invented the 2-of-2 NashX ‘exploding box’ Nash equilibrium for mutually-untrusting trade?

  • How did the FBI really find the Silk Road 1 server in Iceland?

    The Iceland server was so key to finding the Pennsylvania backup server and then Ross Ulbricht himself in SF, but parts of it have never added up. Agent Tarbell’s story about how he supposedly found the IP address never made sense (sounding suspiciously like an obfuscated SQLi attack, raising questions about legality) and he decamped bizarrely quickly for the private sector after what should have been a career-defining triumph, nor has the FBI ever gone into any detail about it (it did not come up at trial due to major strategic errors by the defense). It is also highly suspicious that some fake IDs Ross Ulbricht bought to rent servers were intercepted & he was interviewed in SF by LE not long before the server was supposedly located—quite a coincidence in timing…

    The SR1 investigation was riddled with corruption and questionable actions, and the finding of the SR1 server smells like another case, of a rogue agent or perhaps parallel construction. What really happened in Iceland?

Bad Microwave Tea

Why does microwaved tea taste bad? I discovered this in college, and tea-drinkers agree: heating water in a microwave somehow makes tea taste worse.

There is no obvious chemical difference between H20 heated on an electric heating coil in a tea kettle and one heated by microwaves, so how is this possible?

I suggest that it is not a chemical difference so much as a physical difference, like texture, which can affect taste a lot. Specifically, normal tea has lots of boiling bubbles from uneven heating inside metal or ceramic containers, while microwave heating of glass containers produces (dangerously superheated) even heating and no bubbles or boiling.

If so, then the bad taste of microwave tea may be fixable by adding rough surfaces or injecting air or active stirring.

In college, my dorm room had no access to a stove, but I was right by the break room with a microwave, so for convenience, I would make my tea by using it to boil water in a glass travel mug with tea leaves. But the tea was never as good as back home where I had a regular stove-top kettle: it always tasted wrong, ‘flat’ or ‘hollow’ like decaffeinated tea. I was never sure why. I was using the same tea, and the glass travel mug didn’t seem to be the problem, because regular kettle water worked fine. Was the college water bad in a way I couldn’t taste? Or when I set the microwave, did I heat it up too much? Did it steep too long/too short? Maybe I needed to use a low-power setting for some reason…? I couldn’t fix it and there was no convenient stove, so I eventually decided to just buy an electric kettle.

However, I never forgot it, because I kept wondering why the microwave approach didn’t work. Curious, I later searched and found I was far from the first person to notice this, and in fact, tea drinkers universally agree that microwaving water for tea instead of using a kettle (whether electric or not) results in worse-tasting tea, regardless. So it didn’t seem to be anything about my setup, but a law of nature about water in a microwave. But why? (I have not done a blinded randomized test like I have of mineral water types, because I’m wary of trying to physically randomize cups of boiling water, so let’s take this as a given.)

What chemical difference? It’s puzzling that the method of heating the water should make any difference to the subsequent tea, since no matter how you get to 100℃, it ought to be the same boiling H2O. It cannot add or subtract any chemicals, or in any way be physically different—can it?

Online speculation sometimes suggests “deoxygenation” as the chemical issue, as the lower oxygen capacity of hot water is well-known. I’m not sure how this would work. Cold moving water doesn’t contain much dissolved oxygen to begin with (apparently on the order of only 10 parts per million), and hot still water would contain much less. Does oxygen gas make any taste difference at all at such low levels? And it’s not obvious that the route of heating should lead to any difference in final oxygen gas content—much less make a huge difference much later in the steeped tea that could explain this.

Physics of taste. A more plausible mechanism involves the difference you can literally see: the bubbles during boiling. Microwaved water, because it heats the entire volume of water evenly compared to a hot heating element at the bottom of the kettle, will have many fewer bubbles from the boiling; an example of this is the dangerous superheating effect where a container of boiling-temperature water may be still until you disturb it slightly, at which point it ‘explodes’ boiling-hot water/steam at you.16 The boil can’t happen without ‘nucleation’ sites to form the seed bubbles. A striking example of how important nucleation sites can be is the famous Diet Coke and Mentos eruption effect—it has nothing to do with any chemistry of ‘acidic Diet Coke reacting with basic Mentos’ or anything like that. The Mentos effect is solely driven by the physical fact that a Mentos mint turns out to have thousands of seed bubbles trapped in tiny cracks, which lets the pressurized CO2 gas dissolved in the Diet Coke liquid instantly boil out. Other examples come from food science, where it is well-known that the surface area and texture of food particles are far more important to how they taste than their total volume or mass, because we perceive by molecules docking in taste buds on the tongue & smell receptors in the nose, and the actual mass is irrelevant; so one can engineer low-calorie sugar by making sugar particles with a high surface area and low total mass, which will fit in the same number of sweet taste receptors as the original high-calorie formulation with large heavy sugar particles. Bubbles are even critical to water aeration, as fine bubbles maximize surface area & time-in-water.

Effervescent-tasting. So, the problem with microwave water vs boiling water might be the boiling bubbles themselves! A lack of bubbles, however small they are, may destroy the flavor. It might be the equivalent of wearing nose-clips and then being surprised how hard it is to distinguish potatoes from strawberries, because the aroma is gone. Or perhaps the effervescence is pushing more flavor into the tongue’s taste buds.

Microwave for bubbles? This could be tested by finding a container so rough that microwaved water boils normally (or perhaps a small rough obect at the bottom? not Mentos mints since they would dissolve & change flavor, but something similar), or by injecting lots of small bubbles into microwaved water (something like an atomizer or aerosolizer).

Miscellaneous


  1. And in the case of sports, we also know why it might not be odd if some records set in the 1960s–1980s haven’t been broken yet, and why Mark McGwire & Barry Bonds et al astounded sabermetricians by shattering records that had sometimes stood since Babe Ruth…↩︎

  2. Which raises an additional question about why there appear to be none as far as I know. Does the insecticide/pesticide pipeline screen out any chemical which shows any hint of mammalian or primate biological activity due to the risk, and so all of the interesting nicotinic drugs got discarded long before they could reach the market?↩︎

  3. As distinguished from cases of elaborate private fantasizing like the case of Kirk Allen (“The Jet-Propelled Couch”: “Part I: The man who traveled through space”/“Part II: Return to Earth”, articles republished in The Fifty-Minute Hour, Lindner 195569ya; see also “Behind the Jet-Propelled Couch: Cordwainer Smith and Kirk Allen”, Elms 200222ya), or from the extensive but temporary fantasizing of children at play (well depicted by the 2 sisters of Bluey).↩︎

  4. Perhaps more representative than outright murder of a parental figure is the loosely-inspired-by-Parker-Hulme fictional Simpsons episode, “Lisa the Drama Queen”, involving running away; the perennially popular novel A Little Princess involves heavy elements in the shared fantasizing of Sara & Becky about her father (particularly in the 1995 movie). Another example, involving both running away & parricide, is in the Berserk manga’s 1997–199826ya “Lost Children” arc, where Kentaro Miura appears to’ve taken pains to emphasize that it was not as simple as lesbianism by depicting both as attracted to the male protagonist. (The psychological horror game Rule of Rose may be another example; it is interesting that the developers aimed to ‘capture the “mysterious and misunderstood” nature of girls’, and wound up writing a story about a pair of girls creating a twisted-aristocratic Alice In Wonderland-like paracosm which ends in murder due to unreciprocated love.)↩︎

  5. An example is Esmé Weijun Wang’s The Collected Schizophrenias:

    As Wang narrates the Slenderman story, she revisits her own memory of a fraught childhood imagination. Her young mind has been captivated by the world of The NeverEnding Story, a 198440ya film depicting a fantasy world that eventually includes its reader in the narrative. Wang describes convincing her best friend Jessica that their life, too, was just another thread in the story, crafting a complicated universe of rules to dictate their time together. “We’re just playing, right?” Jessica finally asks, bemused and a little frightened; Wang’s childhood self disagrees, telling Jessica that the imaginary world was, in fact, real: “With my every denial, she became increasingly hysterical while I remained calm. I watched her leave in sobs; I remained grounded in the world of my imagination.”

  6. eg. Silver Sisterhood coverage focuses on the commune/games although, as far as can be divined through their secrecy & pseudonymity & deception, their “Aristasia” sounds like a paracosm, and one which given the ages of the central women when they came to prominence in the 1980s & their reaction to the 1960s, likely started around adolescence and with a specific girl.↩︎

  8. The general abundance of fetish commissions undermines any attempt to explain it as a furry-subculture-specific phenomenon related to OC/commissioning personal-avatar-related art; even for furries, browsing e621 shows that there would still be millions of images if all OC/personalization was removed, and much of that would be commission-related.↩︎

  9. Speaking of meditation, if identity-strengthening maps onto anything in meditative traditions (eg.in Buddhism, perhaps concentration, vs insight or loving-kindness), that would be evidence there are drugs that also do that. Some traditions acknowledge drugs as routes to various experiences (typically, acknowledged only as a bad or dangerous route compared to the meditative tradition, to be done under an extremely skilled teacher if at all—nevertheless, a route).

    So, if there are drug routes to one kind of meditative experience, one would expect there to be routes to other kinds. Indeed, one might reductively expect that the underlying neurological causes might overlap and the meditation is an ‘endogenous’ method and the drug ‘exogenous’.↩︎

  10. But perhaps the missing nicotinic drugs have more impressive effects?↩︎

  11. I’ve always wondered what it’s like to be the non-speaking hemisphere (is it like being a person, or more like being a cat tail?), but it presents similar problems to asking a bat what it’s like to be a bat—if it could talk, it wouldn’t be a bat.↩︎

  12. Although having become much more cynical about psychology and education in particular since I first heard of Bloom’s result back in the 2000s, I would suggest renaming it “Bloom’s 0.5 Sigma problem”…↩︎

  13. Chemical pheromones have been suggested for many things in humans—Frank Herbert invokes them as a possible mob mechanism—but as far as I know, the evidence they do anything in humans is quite weak (the relevant genes are broken and it’s unclear if we even have a VNO), and some of the relevant-seeming hormones even weaker (like the oxytocin literature turns out to be badly afflicted by publication bias). Given the Reproducibility Crisis, can we really take seriously any of these n = 40 studies where “we had some female undergraduates sniff underwear and fill out a survey”? In animals, it’s impossible to mistake that scents/pheromones are an important thing, in a way that they are not in humans—any cat owner will have noticed the ‘Flehmen response’ or ‘gape’, even if they don’t know the name for it (and you don’t have to spend too long around horses to notice it there either).

    And what are the testable implications? For example, meetings held in well-ventilated areas should be disastrous because any pheromone concentration would be diluted far below other meetings. Meetings where you notice body odor, indicating potent bodily output and little ventilation, should go great. Leaders would be well-advised to avoid using deodorant, as that reduces the direct route for pheromone emission. Direct interaction should be weaker than expected as a predictor of bonding/success, because the pheromones are omnidirectional. ‘Mere exposure’ effects should be substantial. People with lower smell acuity should be less affected by meetings as broken olfactory capabilities may break any downstream pheromone sensitivity; anosmics presumably would be entirely indifferent between virtual and real meetings. A (very clear) glass pane should eliminate meeting effects, while incremental improvements in latency, screen resolution, or audio quality would produce small or no gains over the baseline. Gas chromatography could probably identify pheromones and should be able to predict meeting success—while it’s true the hypothetical pheromones may be unknown, hormones/pheromones are frequently in the steroid family, and so my understanding is that it should be possible to measure a “total steroids” concentration in samples which would pick up on any social pheromone and be used in a regression.

    Many of those have not been conducted, but some of them don’t tally with my own experiences. For example, one 2018 conference I attended was what prompted me to ask this—in several cases, I’d known people I met there for years online before, and yet, meeting them in person seemed to make a large difference in how much I trusted or liked them. Good—except most of it was held outside because the weather was so nice and there was a pleasant breeze; everyone got along despite the conditions being awful for any ‘pheromone effects’!↩︎

Presumably for higher-parity births, made more frequent by IVF, there would be combinatorially many ‘identical twin pairs’ eg. septuplets would have (27) = 21 possible ‘twin pairs’, rather than merely 1. On the other hand, many of these are not identical but fraternal, so are little more similar than random siblings; further, higher-parity births should be associated with much greater health disadvantages than even twins, and probably also environmental disadvantages—parents may be able to cope with rearing twins, but the burden of triplets or higher is far out of the norm. And on the gripping hand, they are probably far too numerically small to matter to anything. Still, fun to think about.↩︎
