> I think if people at all levels of skill were reasonably good at measuring their own ability, we would see two curves that roughly overlap. Instead we see the graph given.
Actually, due to the construction of the test, the ability to evaluate your own absolute ability in a subject isn't sufficient for the two lines to be able to overlap.
It's a percentile axis, so you need to be able to reasonably accurately estimate the ability of everyone taking the test, and where you fall in the quartile range of those participants.
