> Russel Barkley
Some of his claims are questionable. AFAIR he claims that:
- ADHD has no advantages
- ADHD has a negative effect on working memory
- ADHD has no negative effect on intelligence
Since working memory is a factor in intelligence, one of these statements must be false.
His political views are also interesting.
> Barkley is a right-wing libertarian. He deeply believes in "Limited government, individual rights, freedom of speech and association, and the nonaggression principle (no one, including the government, has a right to initiate force or fraud against another), and private property rights". He has attacked "the leftist, social democratic or socialist leanings of Facebook's founder and most mainstream media outlets".[35]
I'm not mentioning this to discredit him or because I think you should judge a psychologists by his political views. But I've always associated these views with the assumption that poor people are generally poor not because they don't have the skills, self-discipline etc. needed to be successful but because they are lazy and thus don't deserve welfare. If Barkley, an ADHD researcher, actually believes that he's very good at tolerating cognitive dissonance.
