I had to look up what the "Wason-test" is[1] -- and I'm not convinced it proves people do not have a good grasp of basic logic. I think it shows that people don't see logic as a useful tool in determining the classification of a grand total of four real-world objects.
I think people are just better at optimizing their brain power than that, with just four cards, why not look on both sides of all of them? You examine twice as many cards, but you'll probably complete the task quicker than if you think carefully about the wording of the question.
