Assumptions about Reality

There was an interesting fact, that I remember hearing or reading somewhere. How the world works in a weird way. Because it is the physicists, that have the least assumptions against the reality, and the psychologists have the most assumptions about reality.

There have been some discussion of this problem before. The similar idea is also touched in this Feynman movie Mathematicians versus Physicists.

I just find this fact interesting, and I remember it, so I wanted to share it.
