In remarks laced with scientific inaccuracies, Robert F. Kennedy Jr., the secretary of the Department of Health and Human Services, said on Wednesday that autism was preventable while directly contradicting researchers within his own agency on a primary driver behind rising rates of the condition in young children.
Sure. But the fact remains that autism prevalence in the general population probably looks a lot like the graph about left-handedness of the population throughout the 1900s - that is, logistic growth: growing, but settling towards a relatively steady percentage of the population. Btw, if anyone has a graph of that handy, please post it.
