Paternal age affecting rates of autism got me wondering (not really related to this specific article). We know that autism is inheritable, right? Could it be that autistic men are just less likely to find a partner at a younger age, partly because of social issues, partly because they hyperfocus more on their own interests rather than hunting for a mate. This could influence our view of how much paternal age really does affect rates of autism, since autistic men might just be more likely to have children later in life, with the same rate of heritability as autism always has. Could of course also be a combination of both, but older fathers might not have to worry so much about getting autistic children as the statistics might make them believe.
Needlessly hostile article. Confusing to call him Bird when there's already a communist Kevin Bird in this area. IB would be better, which also happens to be a Danish male first name. :)
"We use family-level fixed effects when estimating the bivariate association between birth order and these outcomes, meaning we are comparing siblings within the same family."
It cannot be a between family confounding factor, as you are suggesting.
Shared environment cannot differ between siblings. By definition, shared environment is whatever causal forces that make family members more similar that aren't genetic.
wanna hear a joke? how do U redpill people?
U cant because of thier mutationbal load hahahahahHAhaha
