The problem is that you are more likely to know how things turned out for successful people than for unsuccessful ones. A policy which has a large chance of disaster but a small chance of great success might appear to be very good under this heuristic, since it worked great for everyone you've heard of.

Excellent point. I was thinking more in terms of social strategies, which don't seem to have devastating black swan outcomes in the way that "guaranteed" gambling or investment strategies do. Is there a pithy way to make that distinction?
