''Rather than you telling me to try reading and understanding what I said, why don't you answer my questions instead of saying they are irrelevent so I can understand what you say?''
What part of ''examining the motives behind beliefs is the key to understanding why people believe as they do'' is hard to grasp?
There are reasons why people form or hold beliefs, which may be unfounded or irrational, desire, fear, faith....so the question: why is the believer convinced of the truth of something that may have no sound foundation, be absurd (flat earth cosmology, etc), irrational, habitual gambling against the odds.
So the question: what are the drivers of belief? What drives a gambler? What drives a man of faith? What drives an ideologue? The psychological drivers of faith and belief being the key to understanding why someone believes whatever they find appealing, satisfying or fulfilling.
