The Word On Altruism

Reading the IHT this morning, I came across this article. It's an excerpt from the book 'Superfreakonomics', by Levitt and Dubner (PL, have you read this one yet??), and challenges the notion that humans are altruistic.

The last line of the article - 'People are people, and they respond to incentives. They can nearly always be manipulated -- for good or ill -- if only you find the right levers' - neatly summarises why we're all in the economics business, I guess.
