I went to a lecture yesterday by a Cornell visiting scholar from Microsoft who recently published a book entitled "Everything Is Obvious: *Once You Know the Answer". The lecture was about the limits of common sense as a strategy for making decisions. I think that a lot of the points he made were applicable to the recent string of chemical lab incidents we've been discussing, so I thought I would point out this as a potentially useful resource for the Chemical Health and Safety community.
