That said, to say they do not influence you in any way is to deny all of advertising, if not the basic reality that the stimuli to which we are exposed in life are the primary thing that shape us beyond our genetics.
Do they make you more likely to feel detachment at the thought of horrors being inflicted upon others, does that influence your career path or political leanings?
The number of times I've seen a commercial for pizza or taco bell or seen a food mentioned on a tv show or movie and thought "hmm that sounds good right now, i'm gonna order that" is way more than 0.
To be clear, I'm against any censorship of violent video games, movies, art, etc.
You can of course argue that school shooters and Stephen Miller would do what they do without all the media (social or not) they've consumed.
That said, what are we, after all, other than some sort of combination of our genetics and environment?
It's hard to argue that there isn't some sort of link between the mention of taco bell and me immediately doordashing it, which makes it hard to reconcile the two positions.
Goatse has been online for thirty years and I’ve never seen anybody say “I would definitely have never tried that if nobody showed me that website”
Are you asking for evidence that humans tend to emulate what they see other humans do?
Are you asking the more direct classic question of if there's evidence that violent media correlates with violent acts?
How do we know this? All I've seen so far is anecdata. As my own anecdata, an ex of mine felt she had been traumatized by watching horror movies at a very young age. Many years later she still had flashbacks.
