Pop!Tech Pop Quiz: Dan Ariely, author of Predictably Irrational (Video)

In the final installment of our Pop!Tech Pop Quiz experiment, TreeHugger founder Graham Hill sits down with behavioral economist Dan Ariely, subjecting him to our Yes/No/Maybe harassment. Ariely's book, Predictably Irrational, reflects his years of (often devilishly clever) research dissecting the way we weigh our options and make decisions. At the end of the vid, Ariely turns a critical eye on the notion of a carbon tax, calling into question the efficacy of a system that would put a price on climate sins.
