This article is not perfect, but it is much better than most MSM coverage of its topic. Here is one good paragraph:
That said, some adults with ADHD are highly intelligent, energetic, charismatic and creative, and are able to focus intently on a narrow range of topics that interest them. David Neeleman, the founder of JetBlue Airways, and Paul Orfalea, founder of Kinko's, have spoken out about how the disorder helped them come up with innovative ideas for their corporations, despite their having done poorly in school.
I have tried to track this point through the research literature, but it still seems to me that the way in which ADHD brings a high variance of attention — rather than just jumpy, scatterbrained behavior — is poorly understood. There is, by the way, some preliminary evidence that ADHD is overrepresented in entrepreneurs.
