Of course. It's not about being reasonable, it's chasing some emotional need that's unrelated to the truthfulness of the belief. But keep alert for the faith-based beliefs you yourself might find yourself defending with flimsy logic too. It's easy to get sucked into the belief that since all the authorities you respect tell you something is true, then it must be, and you don't have to bother much with how valid your justification is because you already believe the conclusion.

A good self-test is asking yourself how you know the Earth isn't flat. Don't do any research, just try to work it out from what you've already observed and think what makes you believe that conclusion.
