Re:in this case correlation is causation (Score 4, Insightful)

Exactly! People here on slashdot seem to have the habit that if they see anything related to a study, they always use the "correlationisnotcausation" tag. Yes, it is good to remember that they are not synonymous things, but in a controlled environment, it quite often is the case. Otherwise, there would be no point in doing any studies about anything.
