That doesn't really contradict his point. It's all about probabilistic expectation. Presumably you have a myriad of options to choose from. If you have a bad gut feeling about one, move on. Obviously there will be counter examples to where this was not the optimal choice, but it is a valid heuristic. Generally in most peoples lives, there is more to lose than there is to gain. You want to skew decision making to minimize potential loss.

Once again, there will be exceptions and people where such an approach isn't ideal.
