If you have too many, your legs are bizarrely long twigs that you totter around on like a newborn giraffe, and youve just gone to far so you wont be a great runner. Or maybe not, because the researchers just act like they are cognitively distinct subtypes anyway, so it might not make much difference in practice. Theres probably not anyone working in math right now who is any smarter than Gauss was. Seriously, what sort of advice do you expect? These questions interest me because I know a lot of people who are bright nerdy programmers married to other bright nerdy programmers, and sometimes they ask me if their children are at higher risk for autism. 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. It really made a difference for him to get to a school where he fit with the other kids. 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. This would also neatly explain how a primarily genetic disease is becoming more prevalent people were always producing autistic children, they just werent surviving before. (*), Its not hard to measure my IQ, except that it generally falls at the top of the scale where the tests dont make effective distinctions. Also also, Crespi is one of those scientists who constantly has much more interesting theories than anyone else (eg), and this makes me suspicious. however, ASD without these two confounders shows no correlation with IQ. Just look at Kanye West, for example. Most genuinely intelligent people are also fairly charismatic. I think top 1% is too low a bar for incredibly. Honestly, your genius doesnt sound very good at digging into people. Observing matters in my local school, I think that child psychiatry is best understood as a means of managing problems that arise in childrens socialization to the school environment, and clusters of diagnoses align with a big three of socialization difficulties: weird dont fit in kids are diagnosed as autistic, restless cant sit still or stop acting up kids are diagnosed as ADD, violent/fighting/tantrum kids are diagnosed with oppositional disorders. There are ways to reduce the loop gain of the system to increase the maximum gain before feedback, but ultimately they involve careful sound engineering theres no general parameter you can turn down to fix the problem, because the primary parameter you _want_ is the same one that causes the breakdown. And so humans recently had/still are having a massive selection for genes that require lower thresholds for immune responses, and genes that outsource some of the immune de-escalation responsibilities to gut microbes and parasites, etc in order to get a faster jump have proliferated to the point where a lot of these are normal now; this is the hygiene hypothesis or old friends hypothesis and the best outline of I can offer for it is the book An Epidemic of Absence by Moises Velazquez-Manoff. And in a sport like wrestling, which is heavily reliant on locks, holds, and pins, having those weak points could easily allow someone to overpower you. But that wouldnt be the way to bet, IMO. 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. This seemed to balance out by late middle-school/early high-school. My understanding is that gender dysphoria is associated with certain structures or traits of the brain- transwomen tend to have certain identifiable feminized brain structures, and transmen to have masculinized brain structures. Some might get lucky and be able to manage the negatives from such unusual prior models away by the effects of other quirks, say having abstract thoughts feel more natural through some particular tweaks making the net their active inference casts wider with higher error tolerance or by lowering the interconnectivity between different oversensitive mental modules that they dont interfere with one another as much or whatnot then you get high-functioning autistic individuals, maybe Newtons one cliched example of that sort of configuration. Check out the similarities. Interestingly, this one addresses the P>V, and V>P subtypes and suggests: children with ASD did not show the commonly understood characteristic profile on the WISC either in terms of PIQ-VIQ discrepancy or in terms of peak skills on particular WISC subtests. I wonder what the genetics for this would look like. psychiatry | Slate Star Codex After further consideration, Im unaware of any phenomenon which would correspond to a low-function, low-intelligence version. I favour the Maxander description of the genetic defect in autism, too much brain development can be bad. Anecdote is not data, which overwhelmingly show a negative correlation between IQ and fertility. A lot of the super smart people I know also seem super interesting either being very funny, uniquely talented, or engaging. Below are two lists taken from an autism checklist and a reactive attachment disorder list. Thats probably how he got to that level. IQb + low genetic load : extremely high intelligence, slight or undetectable autistic tendencies, strongly tenchnically inclined I dont think you can model the autism-IQ correlation using a simple additive genetic model. but heres the thing, I cant come back from the store with six bags of graham crackers and confidently say alright, were gonna make a BUNCH of smores now. To really make a lot, we need all marshmallows, chocolate, AND graham crackersand adding a bunch of one factor does absolutely nothing, and may in fact hinder the whole operationsimilarly, its fallacious to suggest that because some factors dial up, they must all be good things that should be dialed up without limitthat crackling fire is a necessary component, but it doesnt need to go any higherif it does, if we have a big ole bonfire for example, the whole process actually gets harder. For one, its multiple different kinds of mental tasks whose scores are then combined to get an IQ score. This is interesting to me, since I am on a career path to become a high end career civil servant, GS-12 at 25 years old for those that know what that means, and I am anything but normal. Strongly agree. When I was a music major in college it was the research interest of one of my professors and he put the students with perfect pitch through a couple of tests like this in class. I was a bit of an outlier in my family, and didnt really find a peer group I fitted in with until university. And since mental traits like intelligence, social aptitude, and self-control are the ones most likely to be selected for in society, it makes sense that our imbalances would primarily be mental. 2. Heck, maybe there are two different underlying conditions here that have similar enough symptoms that we categorize them together (per Scotts observation in his The Body Keeps the Score review that we tend to categorize psychiatric disorders heavily by effect, because the cause is so murky). This one comes from Gardner et al (2019), which measures the cognitive ability of the fathers of autistic people and disaggregates those with and without intellectual disability. Their free career guide show you how to choose a career that's fulfilling and maximises your contribution to solving the world's most pressing problems. it separates ASD, ADHD, and ID (intellectual disorder). I dont think there was much correlation at all with years of formal education, and the paths their lives and careers took are almost unimaginable now. I find it absolutely bizarre that the intelligence of kids who dont fit in is often ignored. 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. FWIW, I know a few bona-fide genius-level people; on the order of Ph.D. Lilian Grebert is drinking a CAMBIER Black IPA by Brasserie Cambier at Untappd at Home. If the g factor and IQ gains from the Flynn Effect are negatively correlated, then does that mean that IQ tests are gradually being more and more poorly designed over time? Score: I recall it because the lowest functioning children all had loser fathers. 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. Physically, people with autism might have certain brain structures or modes of neural connection that are associated with high intelligence, but without the surrounding neurological infrastructure necessary to support those structures/functions like the poor Great Dane whose heart is too small and bones are too weak for his frame. Brasserie Cambier - Croix, Hauts-de-France - Untappd I feel like unless your definition of normal includes non-highly intelligent this is just so far from true. The result is a total mess. How exactly are you defining normal? Auditory learning is therefore the only accessible means for learning prior to the bridging of other brain functions. I always used to get one word wrong on purpose because I preferred the silver stars. control children (though see the discussion here) for some debate over how seriously to take this; I am less sure this is accurate than most of the other statistics mentioned here. The dangling paren is disquieting enough to have prompted me to make an account: most of the other statistics mentioned here). too many CAG repeats and the area destabilizes and you get runaway anticipation that wipes out later generations of your family. Why conflate diagnosed with autism with has autism? The genes and developmental stuff is one part, an enriching environment in childhood is another, and the physical requirements (adequate nutrition and good health and few toxins present during critical parts of brain development in childhood, continued good health in adulthood). 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). High-functioning autism looks more like the same polygenetic soup one finds with other complex personality characteristics like intelligence or Big Five character traits. (I.e. Some good story make much more in our appreciation of who is a genius than anything else. In the graph of relatives, are autists typically on the border or inside of high-IQ regions? Agreed. She has an article on her website here: https://hennyk.com/autism-and-perfect-pitch/ and a book: https://hennyk.com/book-perfect-pitch-in-the-key-of-autism/. Research suggests that there is an ongoing reversed Flynn effect, i.e. For such individuals, perfect pitch is almost always the indicator that highly refined processing is available in these areas of immediate reception of sound. I have always considered him more naturally gifted than me. If genes for autism (without autism itself) increase intelligence, we should expect these people to be unusually smart. A reasonable guess there is that the smartest engineer on the pyramid project was not much dumber than the smartest engineer working on the Apollo projectthey came up with brilliant one-off solutions to their problems, which didnt stick around because there wasnt much use for them in day-to-day building problems. (When your edit window expires before you submit the edit, it just discards your text and you have to retype it? Indeed, blacks, Hispanics, and Native Americans all have higher levels of overall learning disabilities than whites do. If I suggest autism is effectively what we call people whose mental resolution (in the sense of pixels per inch) is too high, would that make sense to you? High IQs appear to be selected for, as does ASD; while the the survival advantage of the first is obvious, the second is a really high cost to pay from a fitness standpoint, and Im skeptical that the IQ on its own would be worth it as a survival advantage. Couldnt this all be the result of several essentailly different things being lumped together under the label autism spectrum? Even when adults with autism live outside the family, their families especially their mothers have extensive contact and involvement in their care. (PDF link) This was the link from Wikipedia; Im not sure where else to look for the paper. She pointed out that there are a couple widely-used kinds of IQ test. [1] I assume most such genes do something way more complicated and hard to measure, but head circumference makes a nice example trait. This meant that theyd routinely turn them off.
