Hello vanhees:If physicists don't deal with reality than neither to chemists and biologists, which is of course nonsense. The natural sciences deal with reality, i.e., with the objectively observable facts of nature.
Psychology of course does not deal with reality but studies all kinds of imaginations of the human mind. The part of the natural sciences most related to psychology is neurology and brain research.
I think you misread my posts.
I was qualifying my statement about physics being the study of reality... which needed correction as physics studies reality at certain levels (chemists are scientists who study reality at the level of chemistry, biologists are scientists which study reality at the level of biology, etc).
I tend to agree with your sentiments, however, since human beings are real, and if one generously allows that at least SOME psychologists are scientists, they study that part of reality which is human psychology. The fact that humans have imagination or are even sometimes psychotic, etc. is of course some part of reality which scientists want to understand, and those scientists are called psychologists.
