No one has been able to show it does. Which is interesting because it would be easy to do statistically ...since it is a test and is measurable. However anyone saying that for certain positions (ex: QB) it matters and for some it doesn't, they have no proof or evidence. Anyone saying it matters, they haven't shown any proof or evidence etc. Opinions are fine for the most part, but since we are talking about something that is measurable, opinions are sorta silly. Either this does or doesn't matter, and there is no proof.
Someone making the claim that this test is similar to another test (the only way to make such a claim is with very specific test) is speaking on an uninformed opinion. And someone making the claim this matters at all is speaking on an uninformed opinion.
Sorry this test bothers me because people make such a big deal out of it when there is nothing of substance that means anything about it. ALL these scores tell is how good the individual is at taking the wonderlic test. Sorry, fact.
if anyone could provide raw wonderlic scores and we as a community came up with what we wanted to see with them, I'd be glad to run some stats on them and see if this test means anything at all
