Have some fun at Carl Zimmer's blog - try your hand at the famous Wason Selection Task. Then pop back to my site here and tell me how you did, and we'll see whether my readers are typical of the population! Really - the test is very quick, just two questions, and my quick poll is simply a matter of marking the appropriate button(s). And I'd really love to hear how you all do. Don't worry, it's completely anonymous.
The article also tells of a new imaging study looking at the brain activity of people doing a variant of this task, which aimed to show whether the brain works differently when it is solving problems in terms of "social exchange" than when the problem is more abstract.
