It is. I guess I was probably reading too much into it. It is just, if see a widespread practice, I don't want to simply take the most literal possible prediction of what they claim it does, and if that doesn't, then consider them idiots. I will assume people are essentially economical so not idiots as long as time invested vs. some kind of psychological profit gained goes, and want to find out in what other ways does it work i.e. what kind of potential profit it gains, even if just psychological (and sometimes not just psychological but e.g. social).
