Too stupid to know they're stupid.

Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.

Doesn't everyone think they are roughly average and maybe just a little bit better than everyone else?

I'd love to see a chart of how everyone at each percentile point ranked themselves, on average. Not just the dummies.

I wondered about that too, but don't want to pay $12 to find out.
