I think there is a very basic dynamic here. Often it is hard to see some aspects of a system from inside it. Organizations need people who are liminal in order to see the changes they can best make to stay competitive. The rank and file still need to be solid, normal people, but the drivers of change will not come from this crowd. Having ADD, Aspergers, or Dyslexia may be one way of achieving this liminality, but I am not sure it is the only way.
