This only works if it's something people want to believe. If it goes against some existing strong belief, like, "there is a God that really exists", they will continue to believe what they want to no matter how many times scientists, atheists and the like say otherwise. Certain things you will just naturally want to believe more often. For example, people are more likely to believe something fearful. Or something that feeds the ego. Or something that reinforces an existing belief. But the opposite of those things might not influence the person. The illusion of truth is just a heuristic. It's probably how we learn everything as children. We hear things and every time we hear them they are reinforced. Teaching someone that something they've learned is wrong is incredibly difficult.
