Are Psychology and Religion compatible concepts?

Where did you get that from? There's no need to invent things that don't exist. This is something for psychologists to analyze – a person has a persistent idea of wanting to appear as an expert.
People, if you consider yourselves believers, at least make an effort to read the sacred texts of your religions.
Psychologists should investigate this phenomenon – the feeling of being all-knowing. It certainly has nothing to do with religion.
