Whenever the question is brought up how intelligent, educated individuals can be religious (the best example are: theistic scientists), the word most often used to explain that is "compartmentalization".
But how does it work? These people do not suffer from a 'split personality' in a technical sense (where some part of the person does not know what is going on in another part).
Is compartmentalization just a handy concept to offer a pseudo-explanation of a strange phenomenon, or is it real? Are there any psychologists who have published on that topic?
