superfreak“Many of life’s decisions are hard.”

There are many questions in this life that still need an answer. We can turn to all manner of scientists and assorted experts to give us some of the answers, but sometimes the right answers are much harder to find than we may first think. It may be that we’re looking in all the wrong places, and applying the wrong rules. In some of those cases, it might be time to bring in the economists.

Superfreakonomics is the sequel to the popular Freakonomics, written by journalist Stephen Dubner and rogue economist Steven Levitt. Instead of looking at money and banking, the area you’d expect economists to deal primarily in, these guys tackle apply the rules of economics to everything else and see what they can come up with. The argument is, of course, that we might be getting the wrong answers because we’ve been asking the wrong questions.

This book covers such diverse topics as prostitution, global warming, altruism and whaling, exploring each with a strange, sideways glance and seeing what we can learn from one industry about another. Dubner and Levitt explain why a prostitute is like a shopping mall Santa, whether drunk driving is safer than drunk walking, how to track down suicide bombers using their bank accounts, how we can engineer the oceans to stop hurricanes, what Al Gore and volcanoes have in common, and whether people are willing to give up money they haven’t worked for to a total stranger.

Perhaps the most controversial chapter is about global warming. While studying different ways that it could be halted, the pair find out that, in truth, we might not even need to halt it. It might be completely normal. It might not even be happening at all, and our efforts to cool the planet down are actually doing the opposite. The book is actually packed with controversy, as they point out that children’s car seats might not actually be that effective, that the supposed witnesses of Kitty Genovese’s murder weren’t as useless as psychology textbooks like to make out, and that a sex change can affect your standing among your peers.

It’s a quick read, easy to digest and utterly fascinating throughout, packed with the sort of trivia it’s nice to have on hand to trot out at cocktail parties, even if most of it is about car crash victims and hand washing in hospitals. If you’re the sort of person who likes spotting the links between entirely unrelated things, then this is for you. If not, then come along anyway. You won’t be disappointed.
