I think they're referring to the study where it was shown the aggressiveness was raised while playing a game. But if I remember correctly, that same study showed that after gaming, aggression was lower than a control group. So it seems violent games raise it temporarily but lower it the rest of the day.

Which, btw, sports also do

Squeamish adults are generally wise enough to know what's likely going to give them nightmares and avoid it accordingly though.

I know of these, which is why I think the tax won't work.

The responsibility of what games kids play falls on the parents, and that's why the games have ratings. Which is also why the games being taxed are those that are rated as 18+. So the fact that teens are playing them is somewhat of a redundancy.

And I know that most of us played M-rated games when we were teens, hell I played Conker's Bad Fur Day when I was like 8, but my point about it is that even the psychologist they quoted in the article I read in spanish said that the actual solution was for parents to foster a good relationship with their kids. Said article also said that they would probably get around 185 million pesos (roughly 9.7 million USD) from games alone with that tax, so you can probably guess where their goal is actually at
