No, you’ve misunderstood or not read my posts properly.
I provided a link to a narrative paper summarising the results across multiple academic studies, providing an overview of the fact that there is a statistically proven higher likelihood of concurrencr between high IQ and autism, and also summarises the data uncovered by genetic research which explains why that overlap exists (genetic research having demonstrated in these numerous academic studies that many of the same genes underly very high IQ and autism, explaining the clustering of a proportion of autistic people at high IQs, resulting in a statistically significant greater prevalence of high IQs in the autistic population than in the general population.
This article also explained that there is also a clustering of other autistic people at the lower end of IQ, with higher prevalence of this as well in the autistic population than in the general population (usually due to the interaction with other co-morbid neurological conditions which affect brain development adversely).
Effectively, in the general population IQs operate on a bell curve with the extremes at either end being extremely rare. In the autistic population the curve is more like a reverse (upside down) bell curve in shape.
In addition, I provided another link to one of the more interesting academic studies setting out its methodology and statistical validation of this well-documented and statistically significant correlation of high IQs and autism in comparison to the prevalence of high IQs in the general population: this research identified some of the overlapping genes which are noted to be statistically significant in causing both high IQ and autism, providing some explanation of their correlation (although no doubt many more will be uncovered by further genetic research, which is developing very rapidly).
There are many other such pieces of statistically validated scientific research demonstrating the correlation and researching these causes of it, as the narrative paper summarising recent research stated. The second paper I linked to provides one such example of the very interesting and enlightening research on the topic, although I remember reading early genetic studies on this in medical journals going back as far as 2007. There are many more, if you want to search the published peer reviewed research in academic journals which are available online.
