If physicists tell laypeople something that contradicts their experience of gravity, like gravity affecting passage of time, some of them will have hard time accepting it.

Change philosophy of consciousness to study of consciousness, and people would probably dismiss philosophers as well as neuroscientists if their findings didn't fit their experience. I think many philosophers of consciousness cite neuroscientists, so their conditions are pretty special too.
