Survivorship Bias

During World War II, planes used to come back from battle with bullet holes. Researchers recommended reinforcing the parts like wings that suffered the most damage. They said this would increase a plane’s chance of survival. No brainer?

But didn’t the planes that went down get shot in the other areas? Shouldn’t you be reinforcing those areas instead asked mathematician Abraham Wald.

This is known as survivorship bias.

How is this playing out in your life and work?

What improvement areas are you focusing on? What is missing from the picture you are seeing? What are you not seeing?
