But it's not acceptable evidence to use for this sort of thing. There could be any number of reasons why people who start playing SC2 at uni get better grades. It may be that there's a social element which makes them enjoy going to uni more, therefore they are attending class more, and attending more classes means better results. You'll get the same results for the knitting club if someone who really enjoyed knitting and talking about knitting joined. That doesn't mean SC2 causes you to have better grades, and anecdotal indication of correlation shouldn't be taken to mean causation.
As a trained biotechnologist and forensic chemist, I understand anecdotal evidence is not acceptable in a scientific community. The people Venom is proposing this to are not the scientific community, they are going to be average Joes and any evidence he can get will be good evidence for this case.
Any ideas you have to help him out with how to propose this to schools would, I'm sure, be welcomed.
