A weekly post featuring talks by innovative thinkers, sponsored by TED (Technology, Entertainment, Design). This is what the internet was made for – to allow challenging ideas to escape from their academic ghettoes and hang out in a place where they can talk to each other.

I read Kathryn Schulz’ book, Being Wrong, last year, and wrote this review at the time. So it was a pleasure to see and hear her in the flesh. This engaging talk explores the human propensity for being wrong, and its equal stubborn corollary, the propensity for assuming we’re right – even when we’re not. For example, I have a nagging feeling that I might have used this TED Talk before, but that can’t be true.
