Poor Decision Making

When making decisions we are handicapped by loss aversion1 and imperfect information. We often only get to see a single outcome of a decision we don’t get to run that decision out many times, therefore we do not get to see the influence of luck/chance2.

Reasons for poor decision making include 3:

  1. Cognitive basis
  2. Using the wrong mental models
  3. Having the wrong information
  4. Failing to learn
  5. We are incentivized often to make the easy choice rather than the right choice.

Common patterns of poor decision making are often captured in fallacies:
