Bruce Schneier: Liars and Outliers

Check out our conversation on the WELL with security expert Bruce Schneier, who among other things is responsible for the Crypto-gram Newsletter. In this conversation, he’s discussing his book Liars and Outliers: Enabling the Trust that Society Needs to Thrive. Because I’ve been thinking a lot lately about the value and erosion of trust, this book and the conversation on the WELL are especially resonant with my own focus and thinking.

In the book, I wander through a dizzying array of academic disciplines: experimental psychology, evolutionary psychology, sociology, economics, behavioral economics, evolutionary biology, neuroscience, game theory, systems dynamics, anthropology, archeology, history, political science, law, philosophy, theology, cognitive science, and computer security. It sometimes felt as if I were blundering through a university, kicking down doors and demanding answers. “You anthropologists: what can you tell me about early human transgressions and punishments?” “Okay neuroscientists, what’s the brain chemistry of cooperation? And you evolutionary psychologists, how can you explain that?” “Hey philosophers, what have you got?” I downloaded thousands — literally ­­ of academic papers. In pre-Internet days I would have had to move into an academic library.

What’s really interesting to me is what this all means for the future. We’ve never been able to eliminate defections. No matter how much societal pressure we bring to bear, we can’t bring the murder rate in society to zero. We’ll never see the end of bad corporate behavior, or embezzlement, or rude people who make cell phone calls in movie theaters. That’s fine, but it starts getting interesting when technology makes each individual defection more dangerous. That is, fishermen will survive even if a few of them defect and overfish — until defectors can deploy driftnets and single-handedly collapse the fishing stock. The occasional terrorist with a machine gun isn’t a problem for society in the overall scheme of things; but a terrorist with a nuclear weapon could be.
