Considering that most of the anime fans I know in this site (myanimelist) or outside it, are dumb and ignorant as fuck, no I don’t think it makes people smarter The opposite is true for JRPGs and martial arts videogames, because they make your brain hurt more.
I know its counterdicting. Magna and anime, you riot your brain on bad dubs, but JRPGs you have to comprehend things in order to see the ending. Plus all the genius societies claim to play videogames. In the future, our job hiring will be based around how well I play videogames (2020s, 2030s)
