Hmm, I might have to check those out (particularly outliers and blink), after I've got through my current pile:
The Making of Modern Britain
Clarkson: Driven to Distraction
The Undercover Economist
The Alphabet of Manliness
Empire: How Britain made the Modern World
Colossus: The Rise and Fall of the American Empire
Quite a pile, but I haven't read for years, it's the Freakonomics books that have gotten me back into things.
