The authors mentioned in passing that it had been implicated in ADD and sociopathy, and from their tone I assumed it was common knowledge. Then I looked at their data tabulations and my eyes lit up. Unfortunately I should have kept my mouth shut since it is a paper in review and I have to wait until they present it, or it is published, or I ask one of the authors if I can talk about it. (I dislike this particular academic custom a lot). Ian did you write me a note last week about this? Someone on the list did, and I can't find the note. I have mail on 3 computers, scattered, and one of them lost a hard disk, so things are a bit confused.
