I actually think people shouldn’t trust experts too much, period. Philip Tetlock, a professor at Berkeley’s Haas School of Business once did a study. The result is that experts are normally even not as good as non-experts. That’s because they don’t modify their forecasts in the light of new information, as they felt that they knew all the relevant facts. Such kind of over-confidence will blind them from making accurate prediction about the future.
It’s a dangerous path that I see many very smart piggie are going down with.
