...which would excuse you from confusing a poor assumption or a premise "with faults", with a hypothesis. There is nothing scarey about a hypothesis; no bias is shown by an experimenter choosing to have one in his study. In fact, you could not get a study published without one! It is just part of the format.

Pointing out there are exceptions to a correlational study is kind of redundant. The study did not set out to prove that no one who comes from poverty can excell. It did not set out to prove that no one from wealth can fail. If they had, yours would have been a righteous gotcha! Since it was not, what you said was pretty much beside the point.

Simon is an excellent way to measure short-term memory. It is very similar to, but more engaging than some methods that psychologists have used (like repeating back progressively longer series of numbers, for example).

I think that you guys who need to discredit this study are kind of goofy.
