Jim Leitner on Confirmation Bias

Humans in general are biased and look for confirmatory evidence. When someone is bullish on oil, they tend to pick the pro-oil arguments in whatever they read. Very few people train themselves to look forĀ dis-confirmingĀ evidence.

It is very difficult to practice the latter, but you should train yourself to ask why you believe your longs might go down, not why they should go up.
