Risk Savvy: How to Make Good Decisions – Gigerenzer

“The breakneck speed of technological innovation will make risk literacy as indispensable in the twenty-first century as reading and writing were in previous centuries.”

Understanding and dealing with risk is essential in almost every aspect of the modern world; medicine, transportation, education, public policy, even game shows. Most of us do pretty badly at it; despite the fact that you’re more likely to die driving 12 miles than flying from New York to Washington, we feel more worried in the airplane than on the drive to the airport. The response of policymakers has been to argue the need for experts to save us from our biases. Risk Savvy disagrees: what we need, Gigerenzer argues, is risk education. Understanding probabilities is something that can be learned, and must be if we are to function in the world.

Gerd Gigerenzer is best known for his work arguing that though it’s easy to criticize instinct and human decision making as being biased and flawed, in reality those biases actually work better than being unbiased would in the majority of situations. We aren’t broken, leaky beta versions; rather, we operate with a well-designed and effective ‘adaptive toolbox’ one that allows us to successfully navigate a wide variety of situations with considerable success and a minimum of effort.

Gigerenzer is a top academic doing very interesting work in psychology, and I think his academic work makes some great reading. Unfortunately, this book is not that. He’s oversimplified his work, and as a result it often feels like a linear combination of other pop behavioural economics books, rather than a new addition to the field. He has some great examples of his points and some great stories, but nothing new to add to them. Still, some of the facts are really good. Consider the disparate policy approaches between mad cow disease and child proofing scented lamp oil bottles, despite the fact they kill similar numbers of people, or that reading to a 8-16 month year old child boosts their performance on language tests by 7 points, while watching TV reduces it by 17 points. Not world shaking, and not illustrating anything you didn’t already know, but interesting. Still, if I were you I’d stick with some of his earlier books.
