Risk – Statistics, norms & decision fatigue

They wouldn’t think of preventing many statistically riskier parenting decisions so long as those decisions jive comfortably with social norms.

This problem is everywhere – social behaviour decisions, government policy implementations, day-to-day corporate decision-making. The reason, hinted at in the quote above, is two-fold:

  1. Strength of ingrained social norms
  2. Mental effort required to understand statistical risk of decisions

Other potential reasons, I guess, are:

  1. Decision fatigue, or coping mechanisms for it – people avoid making decisions requiring involved thinking if they can get away without them , and
  2. Conflict avoidance – going with less controversial, more socially accepted option, even if it may be the worse/wrong choice.

What can (should) be done to overcome these hurdles? (Other than defining regulation more rigidly to take decisions out of hands of people, and/or ‘educating’ people)
