“Average pilot fallacy”? https://www.thestar.com/news/insight/2016/01/16/when-us-air-...
When designing cockpits using the average dimensions of pilots the US Air Force found exactly 0 pilots who were average in all 10 dimensions. Even just using 3 dimensions only 3.5% were considered “average”. Take the average dimensions of a human hand and draw that hand. Almost nobody has the dimensions of that hand.
