Poker - Hindsight dilemma

In poker, after we make a decision to fold, we continue to watch and judge our decision based on what cards open up. How wise is that?

For example, flop is dealt. We realize the hand is no good and fold. As the turn and river are opened we make an assessment in hindsight if it was a correct decision to fold. It is possible that the turn and river might have been different if we had not folded. Your decision to fold might have determined what cards are dealt as turn and river.

Its a universal phenomenon and almost everybody who plays poker behaves similarly. I am sure most people also use this post facto judgement and shape their strategies accordingly.
