Well, I can see why this was so popular - the discussion is extremely accessible, built as it is on readily intelligible data and a treatment of incentives that draws comfortably on the more 'behavioural' stream of economics (significantly increasing its intuitive appeal), and interesting both in approach and conclusions. It's the kind of book that invites contestation - and, eight years on, I would guess that its huge cultural impact has probably removed much of the novelty that its approach apparently had in the mass market on release - and the regression analysis on which the actual results for which it argues depend is, of course, not presented (and would've been opaque to me, like other lay readers, even had it been included), but having said all of that, nonetheless entertaining and thought-provoking and an interesting, and not clearly off the mark, perspective.
