Psychology and philosophy
An intellectual denial of the ‘here and now’ reality is very much a part of numerous philosophies. Just occasionally this approach has everyday functionality, normally when things look very bleak.
So we can draw a link between survival in the extreme, over-emphasised intellectualism and out of this world philosophies, in all their varieties. Then we can analyze the same with real world psychology (pick a flavour, any flavour) and disappear right up our own arseholes.
