I bet plenty of "uncreative" people could easily do well if you just told them to pick specific things from different topics(e.g. an obscure food, an obscure job, etc...), which is all I did and I scored in the top 1%. You don't have to be creative at all to do that. You only have to think of such a strategy, and then pick some obscure things.
Also, there seems to be some cultural bias - it wouldn't accept chow mein, but I bet pizza would have worked.
Also, the instructions seem silly - the more close to "technical" the terms were that I picked, the higher they seemed to score.
