"One of the things you learn in engineering is to be rigorous. If you build a bridge that falls down on a windy day, there's going to be hell to pay. Financial markets are not like that; they are very noisey. It's hard to tell who's skillful and who's just lucky. And a lot of analyses are done in extremely haphazard, primitive ways, but the investing public doesn't know any better."
