Confirmation Bias

6 of the largest decision-making blunders
  1. Sunk-cost fallacy. Present yourself with the new options at hand -- without considering the sunk cost.

  2. Narrow framing. When we're in situations that will repeat themselves over time, we should take a step back and play a game of averages.

  3. Emotionally driven decisions. Hold off on making important decisions when you are in a bad mood.

  4.  Confirmation bias. Always look for conflicting evidence and then make judgments based on more well-rounded information.

The Paradox of Choice
