It's interesting that they mention the Monty Hall problem. I've found that most of the misunderstanding for it comes from the lack of separation of stages in the problem. People confuse choosing a single strategy versus given probability in stages. It seems much easier to understand when that distinction is made. On a tangent, the part about Africa really ties in well with hypnotism. I'm not sure how many of you have studied it, but hypnotism is full of subtle suggestions like what was mentioned. In fact, it's really just a bunch of suggestions that we have no reason to think critically about. Off the tangent: Considering this makes me wonder how many studies are heavily biased. What a fascinating subject.
