Would you mind looking at the questions I raised for the OP?
I heard a story about one of the pioneers in genetics around Watson's time; a woman, forgot her name, who once walked into a room where two researchers (also forgot name) were building a physical model of the double helix. It was at least a couple thousand plastic molecules. She took a look, said that there was one mistake, and turned around and left.
After studying the brain for years I still can't tell why this happens.
I remember once figuring out that dataset was bad just from the way it scrolled by; everyone was baffled.
Same issues with watching people do stuff, too.
