Ive heard stories of autistic children sometimes regressing in development around 2 years old, e.g. Theyre often chatting about the latest sportsball game or what their kids are doing or their vacation plansconversations that wouldnt seem unusual anywhere in the US. Social relationships are not difficult and people who cannot navigate them are displaying a serious deficit. Below are two lists taken from an autism checklist and a reactive attachment disorder list. Hence the need to go along with pointless social rituals. Avoidance of social situations. Its because we selectively bred dogs to have these traits at a much faster rate than evolution could naturally develop them. What is the point of arbitrary social rituals? I have always considered him more naturally gifted than me. If smart people are predisposed to have autistic kids (which Scott seems very confident of), another trait of smart people is that they tend to get more education than average. Check out the similarities. At the individual level things are generally way more complex than these symptom-based diagnoses and the key is to ask *why* the kid isnt mixing well socially, gets into fights / lashes out, or cant sit still rather than reify it as a brain dysfunction. He initially appeared to learn the names of items when we attached labels with printed words on them around our house. People at the higher end of the corporate ladder that Ive met were very intelligent and also seemed generally normal, though of course they had much higher-than-normal ambition, stamina, and interest in their business. Also, IQ over 70 should be IQ under 70, and people have have autism should be people who have autism. Some of the genetic diseases of Eastern Eurpoean Jews are correlated with intelligence, IIRC, but I dont think they have mental effects. This can best be understood through a tower-versus-foundation model where higher intelligence that outstrips the ability of some mysterious foundation to support it will result in autism (25% confidence), 6. The people who have the genes to be the smartest humans can hit somewhere close to their potential by happening to have the right environment, enough food and no development-stunting diseases during critical times, etc. His auditory channel is very slow and only turns on when you say his name or repeat the question. Being 1.5 standard deviations less socially adept than the average girl might make you weird, but not problematic, while being 1.5 standard deviations less socially adept than the average boy might make you a classroom / societal problem. Possible metaphor: overclocking your computer a bit makes it better (faster), but push it too far and you start getting weird random crashes and end up getting less work done overall. It is known that gifted kids can be misdiagnosed as autism, ADHD or both, but many psychologist never bother doing IQ tests, or do them, but then ignore the results. Does affliction rates vary with age of both parents? (I have predicted conversations, but only because the other person forgot we already had it. Low IQ fathers are less likely to be available due to death/imprisonment/not being around anymore/maybe not even knowing who the father is. He has the making of a superb engineer. Immune systems that greet pathogens with a really forceful response on a hair trigger. Her claim was that autistics often did *way* better on Ravens than on the multiple subtest kind of IQ test. And yes, I know the survey showed that the average SSC reader had an IQ of 138, but Im extremely skeptical of that finding too. It sounds very plausible that the effect of gene variant a and the effect gene variant b alone tweak the machinery in a way that increases its capabilities, but when applied together, they could have a catastrophic collision. Question the first. This shows a) there isnt much of a childhood autism epidemic going on, its more likely that previous underdiagnosis occurred. I think youre exaggerating unilateralism, Hypoborean. Its similar with hearing. If you get a high intelligence person who is smart enough to create a game-changing technology for example, militarized AI or super-forecasting technology then they dont need to get along with low-intelligence people: instead, low-intelligence people need to get along with them. They are being positively selected, ie increasing with every generation, presumably because people with the genes are having more children than people without them. And many types of successful arrangements/balances existbrilliant minds can look very different, and a trait or dynamic good in one person can take another person down if the overall arrangement is out of whackactually, the same trait can lead to wildly different outcomes in the same person. Yes indeed. The familial genes mentioned above: common genes that increase IQ and that evolution positively selects for. Under https://slatestarcodex.com/2019/05/07/5-httlpr-a-pointed-review/ Murphy wrote: disorders like huntingtons where its theorized that theres a tradeoff between risk of death and IQ. Theres a range for this parameter, selection in the past has left most of the population too low, but if you push the parameter up too high things will break. On that and other evidence, its pretty clear the above article isnt talking about autistics like me. Another study showing how autistic people have higher prevalence in inpatient psychiatric units. at 25/26 and Ph.D. at 29/30, so might not be of the caliber of your acquaintance, though. This seems a possible explanation, if high-IQ parents have children significantly later, I like the tower explanation, but not so much the different types of intelligences: maybe autism is a combination of rare IQ-boosting alleles inherited from parents, together with high general genetic load (which, among other detrimental effects, decrease IQ, negating the IQ-boosting alleles). Evidence suggests the null hypothesis. 5. Every year, we get like 4 or 5 students who are just ready for hardcore abstract mathematics from the get go, and since a few years my university allows them to take masters level lectures as early as they want. and they seem just as likely to have unplanned children as less intelligent people with equally bad impulse control. It doesnt really present much evidence for this other than that autistic people seem to have high perceptual intelligence. Im skeptical of the extreme male brain hypothesis for autism. By the same rationale, you could say that no one is normal, and everyone is simply running a mental emulation. I think this is connected to gifted people tend to be good at finding creative solutions to things rather than the most obvious ones, which in the case of weird walking or talking styles can look like autistic behavior. The tower of intelligence needs to be built upon some kind of mysterious foundation. The additive proportion for height is likely higher. My son was measured using the full Weschler and most of his scores were 96-99th percentile (thats VERY high). because it is in line with the current prevalence of autism diagnoses in children, but a bit lower. This fits with my observations of my family (parents, siblings, kids) and other science majors in college. For all his skepticism in some areas, Scott is remarkably accepting of the overall conceptual framework of psychiatric and psychological diagnosis despite its glaring philosophical flaws, which have been pointed out by many (see e.g. I dont know their actual IQs, but Im very confident a lot of people in my bubble are nice, funny, enjoyable, sports-watching people with 99% intelligence. Or the dad may have left or tuned out because he couldnt handle the situation (but could have handled a socially inept kid who wont shut up about WWI airplane models). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6013750/, Increasing repeat length was associated with higher GAI scores up until roughly 4041 repeats. If so, then the top-level geniuses may well have something else going on upstairs to enhance their intelligence, some other difference from the norms, that isnt part of the complex of IQ/autism risk genes. These mutations are often very bad, and are quickly selected out of the gene pool (because the people who have them dont reproduce). This study finds lower heritability than the usual estimates (which are around 80% to 90%; the authors are embarrassed by this, and in a later study suggest they might just have been bad at determining who in their sample did or didnt have autism. You could compare those estimates for IQ to those for height. Its a highly abnormal subset of people. I dont think its quite that and even if it were, it would be really mysterious if double sickle cell genes caused more malaria! I view it as absolutely crucial that bright kids get to socialize with kids like them, and also that someone teaches them how to be a functional person. 9 hours ago View Detailed Check-in. Very simple and wrong toy model: We often joke that my son learned English as a second language, it appeared that his primary language acquisition pathway just wasnt there. Highly intelligent people are likely to have different interests, read and talk about different things, than average peopledoes that make them not normal? Slate Star Codex was a blog by Scott Alexander about human cognition, politics, and medicine. r/slatestarcodex Did recent AI . Strongly agree. Second, even if the test itself is good, autistic people may be bad at test-taking for other reasons for example, they dont understand the directions, or theyre anxious about the social interaction required to answer an examiners quetsions. EDIT: Say you are a bright nerdy tech-aligned person who is attracted to other bright nerdy tech-aligned people; you have a medium preference for eventually having kids but you really dont want an autistic child. There was definitely a sperg-normie dynamic on my last work team, all highly intelligent. A PhD in particle physics at 15 is incredibly impressive, but a programmer starting out of college at an FAANG who saves a bit will be a millionaire by 30. [3] It's kind of sick. (remember that no intellectual disability just means IQ over 70, and so many of these not-intellectually-disabled people may still have low intelligence I wish the paper had quantified this). What if autism does two things: it has a tendency to break enough normal processes to make someone rather nonfunctional, and it also has tendencies to increase perceptual ability and intelligence. 2015, p. 81). Do I say 1.2x that of someone under 30? Or do I say, Not enough data to answer, plausibly extremely high? Im not an expert on biology or genetics or neuropsychology by any means, but I feel like youre onto something with the tower-and-foundation model. Several studies have shown a genetic link between autism and intelligence; genes that contribute to autism risk also contribute to high IQ. There are 5 hyperparameters, the optimal value for all is 9, and 10+ in any causes autism, and each hyperparameter is driven by many genes and different people have different mixes of genes. Thats high, compared to the general population (below 1%) but 50% is weirdly high. Maybe one bias from my statement is Im young, and many of my smart friends are also young. Right, genes are NOT good or bad. While their children are clearly at higher risk for autistic traits, I think they want to know whether they have higher risk for the most severe forms of the syndrome, including intellectual disability and poor functioning. in particle physics at age 15, millionaire at age 30 type of stuff. Any gene that increases A in a normal human makes that human more intelligent by pushing A closer to 10. Rare de novo mutations, ie the autistic child gets a new mutation that their non-autistic parent doesnt have. Why would you doubt it if you dont have the data? with stimulant use (arguably, it also explains a number of non-clinical nerdy traits rather nicely). I had a professor once whose research thesis was basically this applied to language. (*) to complicate matters, in normal usage, Im autistic, but in many usages I wouldnt be described as having autism. paternal IQ/ autism seems pretty much decorrelated, which is strange given the 100% confidence that autism genes are IQ boosting. My parents were optometrists. GS-14 speaking, and Im not exactly normal either. I remember seeing that article 10 years ago and Ive never followed up, so replication not guaranteed. It makes sense to me that the microglia that are involved in both the elimination and growth of synapses could end up producing some brains that are less functional and some that are more functional vs. the wild type based on how the extra pruning is done, what parts of the brain its done in, and when its done. The odds of him actually having Narcissistic Personality Disorder or any kind of Autistic Spectrum Disorder are close to 0. Note that due to conflict of interest she doesn't treat people in the NYC rationalist social scene. Greg Cochran has a paper that discusses this and other IQ/genetic disease in Jews links here. Im not a great student of philosophy, but I dont think most modern philosophers look at the writings of Plato or Descartes or Kant or Hume and think they were intellectual lightweights. But one of his trainers actually had an explanation: A lot of people who casually work out dont exercise all of their muscles equally, so even if they appear to be as strong as him, there could be some muscles that arent as developed as others. You dont need a tower-and-foundation model to explain how both higher than usual prevalence of intelligence-associated genes in autistic individuals and extremely intelligent non-autistic people. IQb + low genetic load : extremely high intelligence, slight or undetectable autistic tendencies, strongly tenchnically inclined Pollution, infection, and trauma might also be in this basket. Her IQ has only been tested once, by a neuropsych, and came in around 90. What are the percentages of children who fall in each group? This article explores piano lessons for non-verbal and autistic students as a means for creating new and necessary pathways for abstract logic inherent in higher education. https://slatestarcodex.com/2019/05/07/5-httlpr-a-pointed-review/ I dont know. This makes a very strong auditory learner. Ok, I just got to the end of the comments and no-one else has brought this up yet: Isnt the finding that Epistemic status: not too bad, certainly good enough to have my old head of department, a grand old neurogeneticist interested in this if still maintaining healthy scientific skepticism. Insofar as autism has a coherent definition, it is a category that embraces a variety of behavioral and neural processing anomalies. Graph B is the same thing, but with people have have autism with intellectual disability. You don't have to be a diagnosed autist to be like that. People diagnosed with autism are less intelligent than average (~100% confidence, leaving aside definitional complications), 3. If a high quantity of a good thing comes with a risk of problems that reduce the quantity again, then you could understand the ability to keep the problems at bay as foundation of the tower. completely unfalsifiable, and 2.) . Hunter gatherers do eat certain roots and tubers, so it's not . How much do we know about how intelligence develops and what might impact it? I dont think 99% would stand out here, but I dont think itd quite be mediocre either. But the Gardner study also ceilings off at 90th percentile intelligence, so at this point Im not sure what to tell these people. For another (Ravens), its a bunch of iterations of the same basic task (a kind of visual puzzle with one piece missing), described here. Autistic people being diagnosed with intellectual disabilities before theyre able to to talk and not really being undiagnosed when theyve demonstrated higher levels of ability is very much a thing. And it would also explain why there are many extremely intelligent people who dont have autism at all (you can build arbitrarily tall towers if your foundation is strong enough). My experience watching a relative currently diagnosed with severe, non-verbal autism grow up is that his diagnosis is a catch-all for he doesnt seem capable of abstract thought but we have ruled out all the other, better-understood potential causes. No one can offer more than conjecture about the cause of his condition, and no one knows how to treat it (unless you listen to the vaccine-chelation charlatans the way that his father does) so why is the medical establishment making confident claims regarding the connection between his condition and high-functioning autism? I havent seen any real evidence for it, or even any real support for the idea as a serious theory. When I was in high school one of my coaches called them, air muscles. Its when a guy can bench 300, squat 500, etc and still get overpowered by a guy who does half that. In primary school, for a while we used to have daily spelling tests, where we had to spell ten words. Would you mind clarifying what you mean by narcissist? I mean, if you go with The Last Psychiatrists standards we are basically all narcissists and to some extent the claim Comey is a narcissist loses meaning. why is the medical establishment making confident claims regarding the connection between his condition and high-functioning autism? Anecdote is not data, which overwhelmingly show a negative correlation between IQ and fertility. Suppose the only study on age-related mortality shows that people older than 30 are 1.2x more likely to die in a given year than people younger than 30, but does not give any other information. So one model is that we should see two things happening at once, as a result of the assortative mating by IQ thats been going on for a couple generations now in the US: a. You might want to adjust for inflation. Maybe this is old news to most people, so I wont belabor that point any more, but what about the link between high IQ and a different immune function? You could also define normal as simply referring to a lack of explicit mental illnesses or emotional problems. She has absolute pitch, an attribute that is quite rare in the general population, but she says an amazingly high proportion of her autistic students have it to some degree, even when they didnt know it. Maybe even only a small fraction of potential arrangements are just right to produce ever-increasing levels of some capability in the phenotype. For one, its multiple different kinds of mental tasks whose scores are then combined to get an IQ score. Draft. The Flynn effect seems to be about raising the floor by building proper sewers and water supplies, eradicating parasites, vaccinating everyone against common childhood diseases, making sure nobody starves and also adding nutritional supplements to foods so brain development isnt stunted by deficiency diseases, eliminating heavy metals from the environment of small children, making sure everyone goes to school, etc.
