11: Survivorship Bias

  • In World War 2, Navy researchers studied the damage to enemy fire returned aircraft and recommended adding armor to areas with the most damage.
  • But mathematician Abraham Wald pointed out the error - they studied only surviving planes. Instead, he recommended armoring the untouched areas, where fatal damage occurred in un-survived planes.

We tend to focus on survivors, ignoring failed cases.

For example, saying “buildings were much stronger and more beautiful in that time and age” ignores that only a few survived and most failed.
