I don't see how stuff like this isn't fraud. I mean, if I gave money to someone, and they told me they would teach me how to cultivate magic beans that would make me happy or rich; and then it turned out that they don't know such a technique, and can't teach it (because it doesn't exist). I see how people get away with this as pundits or advocates because the money involved is indirect (they are lying for position or notoriety, not directly taking someone's money) but teaching a fake science "technique" for money? How is it different than selling snake oil?
