I recently stumbled upon a set of quizzes that ask you to do some preporatory action and then 'think of a [thing].' The claim is that an overwhelming majority of people think of the same [thing].

After 2 quizzes I was skeptical--I didn't come up with the "normal" answer for either of them. A day later, still intrigued, I searched the web for more quizzes of this kind. So far, I've only found one, and when I took that one, I produced the expected result.

This made me even more curious: was this because the third quiz was more effective? Was it the order in which I took the quizzes? Was it the fact that I took the first two quizzes at noon and the other at 5:00 am?

Being a scientist*, the obvious thing for me to do was set up an experiment. All I need is for people to take the test. For my experiment to be meaningful, I need a large, unbiased sample set. This is problematic to me for two reasons: I don't know a lot of people, and the people I know tend to be like me.

This is where you come in. You would do me a generous favor in answering 10 demographic questions and then answering 4 really quick questions (as a control) or performing 4 quick quizzes. You get extra karma points if you tell the people you know about this site. You might be tempted by your goodwill to take this test multiple times. Please don't. It'll just generate a bias.
