»Freakonomics / Blink

I read Freakonomics and (most of) Blink; I had not read Malcolm Gladwell's previous book, The Tipping Point.

Both books address the insight of experts; Blink demonstrates how domain knowledge enables an expert to make a very rapid judgement, and Levitt and Dubner indicate how experts enjoy privileged information, which equates to an economic advantage. Gladwell's experts are sociologists who can tell, in seconds!, whether a marriage will last to five, fifteen, or infinite years; Freakonomics has experts who can sell a house or organize a xenophobic rally.
