Did you read the ones after the part you quoted? Those ones were people who were randomly selected to watch videos with aggression and then were more aggressive. It appears you are only looking at the info that supports your hypothesis and ignoring the others.
Then, the burden of proof is on you to prove that watching those videos actually caused real violence.
Since that type of study is unethical, you CAN'T prove it, as fact.
I just had this same discussion with inimalist, who IS a research psychologist who actually does studies like this. (Not necessarily violence studies, but pyschological studies.)
What inimalist told me is that studies like the one you bourght up prove "little if anything" OUTSIDE of the lab environment.
And, Ms. Marvel is correct. There's a growing body of evidence for causality confusion.
Video gamers who do violent or aggressive things after playing violent video games were already violent and aggressive to begin with: the game just excited them and enhanced those behaviors.
Anabolic Steroid users who get roid rage already were a**holes to begin with and the effect of those steroids on the psychology of the individual is very questionable. (Meaning, Anabolic Steroids have very little if any psychoactive properties.) Just a**holes who go on steroids become bigger a**holes. Basically, it's in their head and not the juice. Those who report enhanced agression do not seem more agressive to friends and family, for the most part...they just feel more agressive.
And, finally, we come full circle to your point. Individuals who do violent things and commit crimes have also been found to watch violent things as younger children. As Ms. Marvel put it, you're putting the chicken before the egg or the egg before the chicken. It is very likely, but still not definitively proven, that the individual had a disposition towards violence to begin with. This has theory roots in both genetics and environment as cause FOR that action (watching and doing violent things.)
Anecdote: My mother told me that I used to fight my older brother and sister, physically, at the drop of a hat. I got into many fights in middle and high school. However, my parents would not allow me to watch rated R movie or play maturish games until I was 13. 😐 I was on a road to violence. I still have to deal with it. I have a criminal mind, but never commit crime. For all intents and purposes, I should be a bad person. I'm not. Guess why? It's all the the damn individual and the choices they make. 😐 None of thise "ohhhh, he watched Rambo when he was a kid, that's why he shot up the bank tellers." B.S.
To relate this on topic: A child of 8 should not see this movie. 😐
