Affect Heuristic

Judgements of risk and benefit follow how an option feels rather than what its statistics say.

People judge nuclear power as both high-risk and low-benefit, and vaccines as both low-risk and high-benefit. In reality risk and benefit are largely independent; the correlation lives in the feeling, not the world.

In practice

  • A board rejects a warehouse automation project as risky while approving a larger untested marketing spend, because one feels mechanical and the other feels like growth.
  • A parent bans a trampoline and drives the children forty minutes to sport four times a week.
