Indeed. If I google for 30 seconds, and see a stark contradiction with what somebody offers, I try not to conclude that that the guy in question is a fool. This is always possible, but rarely true.

Instead I conclude that likely my understanding is lacking, and maybe educating myself a little bit would be beneficial. Either I find out something new and potentially useful about the world, or finally see through a swindle and understand how it works, which is always a good skill to exercise.
