Fallacies continued:

Another "fact" in investment literature that I vehemently disagree with is that "data-mining is bad". Obviously mining data incorrectly is bad, but that's why its called incorrectly, otherwise it wouldn't be incorrect. Finding patterns in limited data over very specific instruments is a recipe for future randomness, but finding patterns of inefficiency in broad areas of the markets over long periods - and devising methods to exploit that inefficiency - is called intelligent investing.

In fact, that is the very definition of learning and wisdom - what else are those words but labels for effective long term patterns?!?!
