Neglect of Probability

For emotionally charged outcomes, people respond to the possibility, not the probability: a 1% chance of something dreadful feels much like a 50% chance, and sellers of protection know it.

An everyday example

Paying heavily to insure against a vivid, rare risk while ignoring a dull, likely one.

What it can cost you

Spending on possibility rather than expected loss; fear appeals that skip the odds.

Warning signs

  • I cannot stop picturing it.
  • Nobody has mentioned how likely it is.

One thing to do

Write the probability next to every feared outcome and multiply by the cost; decide on the product, not the image.
