It has always struck me that in pictures of the moon's surface, what are supposed to be depressions usually look like bumps instead. I'm not referring to the photo at the top of the article; that definitely looks like a hole. But the next one down, under "Observational Evidence", is an example. I find it very difficult to adjust my gaze so they look like pits rather than bumps. I watched the Apollo moon-landing on TV as a kid; even when they were flying in, a few hundred feet over the surface, I couldn't make the craters look like craters, even though I knew they were craters. It feels like I have some kind of cognitive deficiency.
