The autism epidemic may have been caused by assortative mating (people with subclinical autism marrying other people with subclinical autism producing children who are autistic) The sort of people that would do polygenic scoring for IQ are exactly the sort of people whose children might already be at risk for autism (high systemisers) One other effect of this change in labelling, is that studies of autistics before and after the renaming cant be combined into any kind of meta-study, unless they are both much more detailed in their description of the grouyp they are measuring, and happen to target the same people. Autism, and Neurodiversity. Improvements in health care thus cause an increase in the number of autistic children born to more affluent families, but whats actually happening is that were just seeing more of them *survive*. In particular, this aligns well with the observation that de novo variants are more frequently observed in ASD cases with intellectual disability compared to cases without comorbid intellectual disability, that IQ correlates positively with family history of psychiatric disorders92 and that severe intellectual disability (encompassing many syndromes that confer high risk to ASD) show far less heritability than is observed for mild intellectual disability93, intelligence in general94 and ASDs. IQb + high genetic load: autism with lowish IQ, always diagnosed as autist I dont know. The best-studied are probably obstetric complications, eg a baby gets stuck in the birth canal and cant breathe for a long time. Ive known people who were very mathematically and/or technically inclined who had poor social skills. focus on the denotations of words, not the emotional or social connotations. Norwegian founders with an international team on a mission to offer the equivalent of a Norwegian social safety net globally available as a membership. Plus the military is always interested in easy ways to enforce security and they arent too bothered by political correctness, so any automated defense units that I might hypothetically build could also be a profitable side-business for me. Awareness of it? (Which isnt the same as saying its bimodal; the distribution still peaks in the middle, but its wider and flatter.). About 13% of autistic children (in this sample from whatever social stratum they took their sample from) have fathers who are engineers, compared to only 5% of a group of (presumably well-matched?) It is where his bread is buttered professionally, but I wish he would think more deeply about it. However, I couldnt beat the Sophomore at 130 who was my workout partner in the weight room and only had 5-10 lbs on me in most lifts. From a certain perspective, it merges with normal. But they offer a way of grouping types of problem kids that has caught on. This makes it difficult to analyse high functioning autistics separate from those who would have previously been distinguished as having Aspergers. They find that even autistic people without de novo mutations have lower-than-average IQ. 2015, p. 81). Several studies have shown a genetic link between autism and intelligence; genes that contribute to autism risk also contribute to high IQ. By and large, they find conversations with non-genius people extremely boring, because they can predict exactly what the other person will say long before he says it. Poor people have a higher infant mortality rate than rich people do. It draws on the VPR model of intelligence, where g (general intelligence) is divided into three subtraits, v (verbal intelligence), p (perceptual intelligence), and r (mental rotation ability) despite the very specific names each of these represents ability at broad categories of cognitive tasks. A link between Tay-Sachs gene and intelligence. Based on those two correlations, I would be very surprised if it didnt add up to a correlation between predisposition for autism and children later in life. These things are incredibly synergistic in some people, allowing them to do exceptional things, we notice thisso we start to associate them with one anotherbut the presence of one means absolutely nothing about the presence of any others in general, and you need to scale up all or at least many of them to get any good returnsworse, some factors may not need to go any higher, otherwise theyll just be a hindrance. And this is a productive comment because? Level measurements also seem consistent with possible causes being differences in responsiveness to oxytocin rather than differences in normal concentration. The mean could easily shift without creating a bunch of geniusesit is probably much easier to raise the IQ of average or above average people, just through some relatively basic improvements and guidance. My crank theory is that autism, when looked at through the environmental toxins are causing Very Serious Problems lens, starts looking suspiciously like an environmentally induced phenotype, https://en.wikipedia.org/wiki/Genetic_assimilation. Also, if anything, it would be self-control thats being selected against by modern reproductive behaviors, not intelligence. However, history doesnt always predict the future. (*) to complicate matters, in normal usage, Im autistic, but in many usages I wouldnt be described as having autism. 3. This study of 45,000 Danes finds that genetic risk for autism correlates at about 0.2 with both IQ and educational attainment. I still sometimes feel bad about whether that ended up slightly ruining some sort of investigation into which methods of teaching spelling were better or something like that. (Apologies for a machine metaphor that is certainly misleading, but better than anything else than I can think of.). (And maybe theres some kind of subtype of autism > size of correlation thing happening, too. I think (as an interested amateur, not an expert) that the most plausible answer is that human intelligence depends on getting lots of stuff right. There is also some link to male sex, I do believe that there are higher levels of males with low intelligence autism. In some sense, all autism has such-and-such characteristics studies are studying the way people like to define autism, and tell us nothing about any underlying disease process. If the curve stayed exactly the same and there was a correlation between IQ > arb. For what its worth, I was diagnosed with Aspergers (which has now been folded into autism) at age 12 and as part of the diagnosis they did an IQ test with a processing IQ component and a verbal IQ component, and although the documents I have dont list the actual scores, the result is referred to in the documents as being very high in the verbal component and very low in the processing component. 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. Social rituals are incredibly important though, humans are social animals. List of Probability Calibration Exercises - LessWrong German Shepherds, Huskies). Theres a new paper out on how the frequency of variants that affect educational achievement (which also affect IQ) have been changing over time in Iceland. We are both university qualified. Social relationships are not difficult and people who cannot navigate them are displaying a serious deficit. Question the second. What led me to ask this is stories of people who were deaf from birth whod get cochlear implants as adults. A simple model might be something like the genes for color vision. Is it because that is a trait many people here associate with passing for normal? On that and other evidence, its pretty clear the above article isnt talking about autistics like me. As a result, they have unbalanced physiologies; their bone and cartilage may not be strong enough to support their frames, their hearts may be too large or too small for their bodies, their nasal passages may be truncated because their snouts are shorter than the rest of their genetic blueprint expects. Blindness, Schizophrenia, and Autism : r/slatestarcodex Autistic people have weird developmental trajectories. no IQb + hgl: very low IQ, non-autistic mental disorders. The reason seems to be that there is great overlap in symptoms, although there is great diversity in symptoms. Anecdote is not data, which overwhelmingly show a negative correlation between IQ and fertility. It turns out that giftedness can be quite a burden for children and teenagers, as not many of their peers can relate to them and vice versa. We have another child who shows no autistic traits. If were gonna sit down and make Smores, we need marshmallows, chocolate, graham crackers, and a crackling fire. Thus, the question under discussion becomes does every highly intelligent person have some of these autism-linked genes, or are there other paths to high intelligence that do not involve these genes?.
