When left handedness was seen as a disorder and students who used their left hand were beaten, rates of this disorder were a few percent. When the idea of left handedness became mainstream, rates skyrocketed and we know the base rate is about 10%.
Homosexuality was considered a disorder in the DSM until 1974. Self-reported rates of homosexuality have skyrocketed since then. Most likely explanation is that the true base rate has not changed, just society's measurement of it.
Children with ASD in prior generations were labeled as delinquent, troublemakers, retarded, or were abandoned by their parents and communities.

Or are these my preconceptions and biases?" > and we know the base rate is about 10%. Sinister. I think it would be cool to be left-handed in a country where the language is written from right to left.
- taneq 3y ago> Sinister. A dexterous response, to be sure. ;) I find it interesting that the rates of a whole bunch of these uncommon-but-still-prevalent differences seem to cluster around 10%. I can't help wondering if it stems from prehistoric humans living in small group of 20-30, so each band would have on average 2-4 of each, giving the group a wider range of capabilities than they would otherwise have.
