Can a reasonable person believe regardless of evidence in ghosts, in deities and gods, in folklore, in aliens, in superstition, in the importance of themselves, in their culture or nation, in their position in society and their gender roles, in mums cooking being better, in bad luck treating them unfairly, in the importance of their habits and rituals, in sticking to how they’ve always done it, in any number of irrational things that they hold close to heart?

I’d say apparently they can. People are not logic processors. People are people.
