Conspiracy theories are non-falsifiable. In my experience (as one who was very much into them when younger), the vast majority of their proponents will never drop them. They are emotionally wedded to them.
Yes I agree.
Conspiracy buffs also are not comfortable with the common sense of “Occam’s Razor”—the tried and true universal principle that the vast majority of the time, the true “solution” to a situation or a problem is the one that has the fewest assumptions.
