@Fil Albuquerque,
Okay. Religious belief is also, within the core of the believer, a passive, agnostic stance; but it appears otherwise due to its extreme nature. The endless uncertainty permeating the universe abounds with the question of Gods existence. With your lottery ticket there are many probability thresholds which may be used to reasonably infer you aren't going to win the lottery. With the God question, these probability thresholds break down as the question is universalized. This is just the nature of the question. Rationalizations universalize, forming extreme positions which disregard most probability inferences.. Resolution for Gods existence, as with whether you win the lottery, is impossible; or at least does not happen until death. So God is the source of the utmost extremism..
As you also say, there is willful delusion. But your mildest hope in winning the lottery is a mild delusion. Due to the nature of religious thinking, this mild optimism transforms into an extreme hope in remote probability.
Religious believers are not certain of their belief; nor can they be. The belief does not crystalize into a certainty. It only appears this way due to the extremism.
These religious questions and considerations of extremes are unavoidable. I agree it is a liability, and how individuals resolve this defines their path in life and has plagued cultures... Within the self resolution is still necessary. Transcendentally I reconcile all beliefs as true in their own psychic senses. Their apparent logical incoherence is a communication problem.
