Individuals with high verbal IQs and a borderline or below average functional IQ make great priests. Since these individuals are dysfunctional and nonproductive members of the society, they are unable to even financially support themselves for their basic needs. Hence Churches and Mosques thrive on charities and donations. The issues of low self-esteem which manifests in an eternal desire to be treated with special respects. Hence the titles of The Reverend, The Holy, The Ayatollah, The Maulana Sahib, Pundit Ji. As long as this internal turmoil stays dormant it bears a false smile and the world smiles back at them. Their volcanic state is visible only in fiery sermons. They are like time bombs ready to explode at any moment. When this volcano erupts its perils are limitless.
Long before William James, The Quran beautifully describes the intellectual misery of the Religious Fundamentalists. The following is a conceptual translation from the first chapter of The Quran, Al’Baqqara, from the very first few pages.
[Inn nallazeena kafaru sawa un elay him aa anzartahum umlum tunzir hum la yuminoon']
Know this with absolute certainty that those that choose to disregard The Laws of Allah 
and instead engage in magical thinking, [the religious fundamentalists = Al Kafiroon] whether you warn them or caution them of the dangerous consequences of their magical thinking, they can never have an ability to appreciate an ideology of life based upon rational thinking leading to a program for a peaceful life for all mankind. [Al Iman] 2:6
[khattamallah ho ala qalloobeyhim wa ala sammeyhim wa ala absaareyhim gheshawatun walahum azzabun azeem ]
Allah certifies and endorses that these religious fundamentalists have a mentality that shuts their faculties to perceive and determine. They have
limited intellectual capacities and indeed are in the worst form of misery. 2:7
[wa minnun naasey mai'yn yaqqolo aa manna billa hey wa bil yaum mil aakheratey wama hum bey momineen.]
Amongst the mankind are persons that claim to be the genuine promoters of peace in the world, and believers in Allah or God, and in the hereafter. They (The Fundamentalists) are certainly not the true peace-givers or The Momins. 2:8
[ yukhadeyoon nallaha walazeena aamino wama yakhda'oona ila anfusah hum wa ma yash oroon ]
