Banks are run by executives, and executives protect themselves, and that does not always mean that banks are going to behave rationally.

We think, each of us, that we're much more rational than we are. And we think that we make our decisions because we have good reasons to make them. Even when it's the other way around. We believe in the reasons, because we've already made the decision.

Many ideas happen to us. We have intuition, we have feeling, we have emotion, all of that happens, we don't decide to do it. We don't control it.
