Late reply but for those who read this later: careful when wanting to know what is "the norm". It's social ideals, mostly. (And if it were statistics, where would we draw the line and why ... homosexual ... disorder?) -- Yet luckily, "disorder" means illness, while a non-valueing statistical out of the ordinary would rather be called "divergent".

Relevant quote from the article:

Whilst [neurodivergent] traits were celebrated in the modernist era, they increasingly began to show up as problems in the Britain during the 1980s – meaning that something had changed in British social normativity. Interestingly, according to critical psychiatrist Sam Timimi and colleagues, this largely happened in light of the rise of the neo-liberal market system, and in particular the services economy. In particular, this economic shift began to alter the notion of the ideal male: rather than being fixed in focus and obsessive, men increasingly now had to forever shift into new roles and to constantly sell one’s “self” in order to fit in. Members of the workforce, in other words, now had to become increasingly agile, flexed, narcissistic, and hyper-social in order to succeed and be valued – and this economic drive became reflected in social normativity at all levels of society.
