Excellent example of focusing on the right thing:
During World War II, the Allies mapped bullet holes in planes that were hit by Nazi fire. 1/7
During World War II, the Allies mapped bullet holes in planes that were hit by Nazi fire. 1/7
They sought to strengthen the planes, reinforce areas heavily damaged by enemy artillery to be able to withstand these battles even more.2/7
The immediate decision was to rebuild and reinforce areas of the plane that had more red dots (or received more bullets). Theoretically, it was a logical deduction. After all, these were the most affected areas. 3/7
But Abraham Wald, a mathematician, came to a different conclusion: the red dots represented only the damage to the planes that were able to return, that came home. 4/7
The areas that really should reinforce, were the places where there were no points because these are the places where the plane would not survive being hit. 5/7
This phenomenon is called survival deviation. It happens when you look at the things that have survived, when you should focus on the things that didn't.
What are you looking at in this crisis? Where are you taking bullets and where should we act? (Unknown author) 7/7
