I didn't deliberately set out to find it, really. I'm also not quite sure how well it works yet. The effects are supposed to be cumulative, meaning the longer you have been taking it, the more of a confident jerk you become, and you continue being a confident jerk even after coming off of it (maybe). I doubt it's that much of a game changer really, it's a pretty commonly used nootropic and not many people list improved confidence as one of the effects--perhaps because the effects are subtle and only come with continued usage, or perhaps because they simply aren't very strong effects to begin with. It might be useful for people who have chronic social awkwardness though.
(if anyone reading this ever sees me act like a confident jerk, please tell me)
This description doesn't really make me want to use it. At all.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
