I'm surprised that this article left out how the training of the chick sexers actually happened. Apparently it was: - trainee picks up a chick and looks at the rear end - they say "male" or "female" - the instructor is standing behind them but offset so they can look over the should of trainee and still see the chick - the instructor says either "correct" or "incorrect" - this goes on until the trainee hits some level of accuracy The thought here is that this is building a subconscious (some might say "zen like") ability to determine the sex. This is also why the successful trainees can't explain how it works: they weren't give explicit instructions to build a mental framework. Some other examples of this: People who learn a language organically at home vs in school. E.g. it's easy for me to translate Spanish to English b/c I learned it in high school. It's harder for me to translate Italian to English b/c I learned Italian organically and not via vocabulary mapping and class instruction. Another example is the egg sushi scene from Jiro Dreams of Sushi. The junior chef just makes egg sushi every day until Jiro one day says "good".
