The most amazing part of this blog is finding out what amazing things otherwise intelligent people can find to be surprised by. That makes this place a gem beyond price.

Can you think of a single Kerviel or Leeson who was caught, fired and hung out to dry after the bank noticed he was making far too much profit for them?

Having worked in the futures and options trade (not, happily, as a trader), I actually have seen someone fired for following unhedged trading strategies that turned out to temporarily profitable. He was extremely surprised, particularly since he simultaneously received a sizeable bonus from his activities, but some of the old gray heads in the office understood. Bias evaporates like first frost when you have to make a hundred bets per day, every day.

Participants in the study may believe that they themselves are fallible judges of ethics. If that is the case, then it may be rational for them to update their judgment in the light of new evidence relevant to an ethical judgment. Specifically, one thing that is relevant to an ethical judgment is what it is reasonable to expect as the outcome of an action. The more reasonable it is to expect a bad outcome from the action, the more likely it is that the action is ethically suspect. And our judgment about what it is reasonable to expect is in turn informed by our experiences of what actually happens. The more often we observe that A leads to B, the more reasonable we judge it to expect A to lead to B. And in this study, the participants did in fact observe (or think they observed) one case in which the action led to a bad outcome.
