Epistemic status: wild speculation backed up only by anecdotal evidence and theory. was too big to go through the birth canal! Anecdote is not data, which overwhelmingly show a negative correlation between IQ and fertility. A 120 year old comes into my office and asks what her risk of death next year is. I strongly doubt that. Its similar with hearing. She hoped to use this theory to explore why some autistics show delayed language acquisition. Probably not the most important feature of this research but its a thunderous argument against modern day IQ-obsessed cryptoeugenicists. There is another problem: Giftedness also increases empathy, which in the wrong environment can be a bad thing. Compare to this study https://bmjopen.bmj.com/content/9/8/e029040.full based on the scottish census data. Crespi suggests that autism is marked by an imbalance between P (as the tower) and V + R (as the foundation). Insofar as autism has a coherent definition, it is a category that embraces a variety of behavioral and neural processing anomalies. He (I presume) seems to be a bad conversationalist, likely through lack of practice. I have read before that age of parents increases risk of autism. 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. Get the latest business insights from Dun & Bradstreet. 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. Are there other mental disorders that track with intelligence? 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. I could easily see someone unable to focus, stuck in a room banging their head just trying to make the noise go away. 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. ABA research, like autism research in general, suffers from an appalling lack of rigor. 46.8k members in the slatestarcodex community. Polimanti and Gelemter (2017) find that autism risk genes arent just sticking around. And autistic people have more health issues than non-autistic people do. Maybe even only a small fraction of potential arrangements are just right to produce ever-increasing levels of some capability in the phenotype. And thus a little more involvement from the microglia in utero or during early childhood might lead to a more efficient neural configuration and a higher IQ, especially if the involvement is more concentrated in the brain regions with more of an evolutionarily enforced margin toward resilience/survival rather than cognitive performance in normal humans. No ICU or anything that severe, but still something that differentiates her from the other children. Maybe specific areas for different such quirks of processing have some optimal Goldilocks zones for their values, which if all fit might give you some sort of the upper bounds of human intelligence-maybe there are multiple such optimal/viable configurations, however hitting all the targets simultaneously must be relatively rare, and some of the targets might be smallish, others might be essentially fixed without some de novo mutation for likely good evolutionary reasons. It really made a difference for him to get to a school where he fit with the other kids. In the 1800s, the average US man weighed about 155 lbs. Autism, and Neurodiversity. comments sorted by Best Top New Controversial Q&A Add a Comment More posts you may like. If you're interested in testing yourself and contributing to their project, check out their questions page. This is very very crude model that does not take into account how DNA and sexual reproduction works: it is middle of the night and that stuff is not my strong suit; however, I like this description and with my limited understanding, it may even carry some resemblance to reality: I will bet a considerable sum of money that a model where one simply assumes that Q = f(g_1, g_n) = a_1 g_1 + + a_n g_n for unknown constants a_i does not describe how these parameters affect intelligence (get all g_i that are positively correlated with IQ, combine them, and you get a super-enlightened being!). IQ dropping over recent decades in many developed countries, combined with lower TFR for high-IQ isnt evidence? people that are 30% autistic have average IQ X. 10.0 is the optimal learning rate, and 9.5 is good, then 10.5 is typically also good. If the extreme male brain hypothesis is true, then those girls have unusually masculinized brains. no IQb + low genetic load : high intelligence, sociable, not so technically inclined There could be something similar going on with autism. Our ages when our son (1st child) was born were 27 (me) and 26 (my wife), and for our daughter (3rd child) we were 31 and 30. Graph B is the same thing, but with people have have autism with intellectual disability. Under the DSM-5, autism is characterized by persistent deficits in social communication and interaction across multiple contexts, as well as restricted, repetitive patterns of behavior, interests, or activities. I dont think cystic fibrosis works that way. One just needs to consider a model where a brain is a complicated object whose organization and function depends on changes in the genetic blueprint in non-monotonic ways, and it is likely that all combinations (attainable via sexual reproduction) of genes that are beneficial alone or in some particular arrangements are not even more beneficial together; some of the potential arrangements are bound to be non-optimal or even catastrophic. The reality is that weight training only increases strength in the motion of the lifts that you do. 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. Genes which are helpful until you have too many of them, at which point you are screwed. If females have a higher average baseline social competence, it would stand to reason that even the impaired girls would remain above the diagnosis threshold in greater numbers. Some good story make much more in our appreciation of who is a genius than anything else. Hard to specify. I dont have time to go through all the links this morning but wanted to add some more studies. Indeed. And at least a few of them were probably just lying outright. In this study, however, we see strong heterogeneity of genetic overlap with other traits when our ASD samples are broken into distinct subsets. Why on Earth one would assume that the effect of genes that contribute to IQ should be linearly additive and increasing to ad infinitum. Someone at the 99.0 percentile for intelligence would probably seem quite mediocre by SSC standards. 5. I.e. Substack is a blogging site that helps writers earn money and readers discover articles they'll like. The tower model looks close to my personal model, which has absolutely no experimental testing besides how the two of us feel about itbut generally I call it the Smore model. But the Gardner study also ceilings off at 90th percentile intelligence, so at this point Im not sure what to tell these people. Some of the stuff she says about this seem a bit woo-woo, but interesting anyway. Im really curious, how many people identify with this statement? Given the problems measuring IQ in autistic people (spiky profiles, huge differences between ravens vs. weschler) its also possible that intellectual disabilities are overreported at 15%. It would explain the association of genes for intelligence with autism (holding foundation strength constant, the taller the tower, the more likely a failure). In other words, if your perceptual intelligence is much higher than your other types of intelligence, you will end up autistic. What are the percentages of children who fall in each group? No background in finance required. This model predicts something I believe is true many low functioning autistic people have real talents lurking in there, it is just really hard for them or others to access those talents because of all the broken stuff. Non-autistic geniuses are compatible with the proposed hyperparameter model, unless Im missing something. Flynn effect vs genetic selection. Keep in mind, my sample size is small. First, these two children were the only children where my wife was working while she was pregnant. So I gave that fact to save others the effort to dig for it, while trying to give a subtle hint to you that it is better to include the finding. We start with a presentation of a summary of the article, and then discuss in a friendly atmosphere. Arizone State University Autism symptoms reduced nearly 50% two years after fecal transplant In the graph of relatives, are autists typically on the border or inside of high-IQ regions? We have another child who shows no autistic traits. 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) Go up a level and they can tell you the pitch of your hair dryer. i do wish you wouldnt use the phrase autism risk. 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. He taught himself the alphabet before he was 1 year old. Most are weird in the sense of having uncommon interests (reading history or science books or studying languages for fun, say), but most seem pretty normal in terms of personality and affect and such. And this is a productive comment because? My outside view intuition is that gut bacteria are the new priming and also literally HTTLPR. And so those are genes that show up as giving you a bump in your IQ in populations genetic studies. Plenty of people are both smarter and more charismatic than us. Since the definition of autism (as noted by Scott and discussed elsewhere in the comments) is primarily symptomatic, that means you only get the diagnosis if you display symptomatic behaviors meeting a certain noticeable threshold. Or maybe not, because the researchers just act like they are cognitively distinct subtypes anyway, so it might not make much difference in practice. More, you have probably already settled into an existence that minimizes their importance to you by the time you have enough information to piece together the importance of predictability. Norwegian founders with an international team on a mission to offer the equivalent of a Norwegian social safety net globally available as a membership. Normal is being concerned enough with appearing normal to try being normal, yes. Maybe this is a tower collapse event. however, ASD without these two confounders shows no correlation with IQ. The selection findings are across historical time, not recent industrial time, and theyve found that IQ is being selected for as well. We cant do much about the genetic or random developmental stuff, but we can make sure most of the things that have stunted peoples intelligence over time go away. Other interesting question if the Flynn effect is more important than genetics and our mean IQ is 15 points higher than 100 years ago: where are all the geniuses? Over the vast majority of the range of the main volume knob on the mixer (assuming the system is set up reasonably), more will be better. If e.g. It would be interesting to see more fine-grained dependency between autism and IQ, i.e. Disguised in that almost is a very slight tendency for fathers to be unusually intelligent, plus a (statistically insignificant) tendency for them to be unusually unintelligent. My son was measured using the full Weschler and most of his scores were 96-99th percentile (thats VERY high). So the only question is whether the size of the effect is enough to fully explain the data or whether, even after adjusting out the degree to which autism is caused by mutations and environment, it still decreases IQ. Instead of autism causing low IQ, low IQ (in a mental architecture that typically causes high IQ) would cause autism, and then of course when you look at the relatives of a downwards outlier you will find higher IQ. Being a deadbeat or loser, or being perceived as same, may be a result, not a cause, of the specifically low-functioning types. 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. Is it the reverse of that? Aspergers was definitionally distinguished from autism due to a lack of the cognitive deficits associated with that condition, but in 2013, the DSM-5 folded it into autism spectrum disorders, so this could make it difficult to analyse the genes of high function autistics if that was the mistake I believe it was. The existence of a well-defined subset of low IQ people whose relatives have higher-than-predicted IQs is a surprising finding that cuts through the measurement difficulties and suggests that this is a real phenomenon. Not just running an emulation of normal to deal with other people? Plausibly, a certain amount of narrowness and rigidity of focus will improve cognitive performance, whereas too much will cause impairment by making it too hard to get the big picture, switch attention and deal with competing stimuli etc. b. So, one can see how this would obviously lead to an increase in autoimmunity, but in one of the later chapters AEoA, Velazquez-Manoff also shows how autism (a least a lot of the time) is an inflammatory condition: for instance, autopsies uniformly showing neural inflammation, people with ASDs are more likely to develop autoimmune diseases than the general population and are more likely to have family members with autoimmune diseases, and for a few subjects treatment with immune-modulating intestinal worms providing some symptom relief even. Several studies have shown a genetic link between autism and intelligence; genes that contribute to autism risk also contribute to high IQ. Greg Cochran has a paper that discusses this and other IQ/genetic disease in Jews links here. Girls also get autism, but seem to stay undiagnosed much more often. Id cheerfully get in bed with the military-industrial complex -in fact, Id probably be rock-hard the whole time. (So I dont understand why confidence goes down so much for point 5 in the conclusion of the original post, from 80 to 25 percent.). 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/. This probably calls for some elaboration. I believe this is also the case for artificial neural networks, unless you are in pathological regimes that are too unstable to be useful. ASD has no reliable early predictor, no unitary developmental course, no unitary life outcome, no unitary recurrence risk, no unitary pattern of BAP features, and no standard homogeneous subgroups. 2. (Note that if autism is really one thing [not a complex syndrome], with high and normal functioning individuals, and high vs normal correlates with IQ, then if you only measure the normal autistics, youd get results like the above, due to sampling bias.
