Psychology isn't a problem as such.
But there are serious problems with the quality of the work that has been done in the past, and is being done.

Too much of it is "built on sand", which makes it very difficult to know which studies can be trusted.
And widespread politicization of the science makes it even worse.
Yeah, pretty much.
Also, to add to this, one thing that comes to mind for me is the idea of bias, or lack of knowledge about topics that connect to a specialty of the ones running the experiments.
For instance, someone doing these tests and all this stuff, maybe they're very good at psychology or you know, the science stuff... but if they have no REAL knowledge of video games (which absolutely includes first hand experience), and everything surrounding them, to me it renders the results totally worthless. They're good at asking the questions. But they have no bloody idea what questions to ask (and they dont realize this). So to speak. And it's not just a matter of knowledge, but also experience, and I'm going to take a guess and say that those running these tests have pretty much none of that... call it a hunch.
The whole reason I'm so confident on what I make of the whole thing is due to the sheer amount of experience and knowledge I have related to the subject matter. I've been doing this for decades, I've spent A LOT of time with competitive games (fighting games mostly), and a lot of time observing and interacting with others who are a part of the hobby. On top of that, I have experience from the other side of the fence, AKA the developer side. I've been able to witness both the best and the worst of player behavior... often in person... and have enough knowledge of the design elements behind the games involved to know what specifically is most likely to act as the point of influence that starts the anger train. As well as understanding the hidden psychological manipulation techniques employed by the nastier publishers, and that absolutely is an element here too (after all, aggravated players absolutely generate more attention towards the product).
But... those running these tests and making these papers probably have none of that, and likely arent even considering that these things may be involved. Despite that it is absolutely all linked to the main subject.
And of course, while many people of a scientific inclination have a tendency to declare themselves as purely objective/logical and free of bias, well... yeah, that's not how any of that works. Any sort of dislike, resentment, or disdain that could be dictated towards the hobby or those who are a part of it, influences ALL of this, whether they're aware of it or not, and no matter how strong they believe their self control to be. The effects of those things are rather similar to the reasons for why the old opinion of "it's ruining our kids" was so common way back when. Parents didn't understand any of it, and what they saw, they often hated. And they did not at all bother to learn more about it. As many kids who grew up during the arcade, or NES/SNES eras likely remember. A similar phenomenon to the weird D&D mess that happened a long while ago as well... parents were freaking out and thinking that D&D would bring their kids into horrible Satanic cults, that sort of thing, because oh no, there are demon monsters in it... and they never bothered to look into it enough to realize that it's the players AGAINST the demons and monsters in the games. And so they would try to dictate things related to what their kids were into, without having any understanding of those things.
Also yes, the politicalization of things like this doesnt help. Some people are just so quick to give... ahem... "results" if those results provide them with some sort of benefit. Not that they'll admit that, of course.
Honestly, I could ramble for pages and pages about this, but I'll spare you all that.
My girlfriend occasionally listens to true crime podcasts, and the handful of times that I have overheard them, I have had some of the most insane and vivid nightmares I've ever had in my life.
For what it's worth, I can sympathize with you on this one, though for me it's not the same source. It's that stupid shouting rectangle in the living room, which is ALWAYS turned up to a high volume. The media being what it is, it's always one scary thing after another scary thing, and even if it's very clearly exaggerated or inaccurate, it still has an effect on me immediately, as much as I hate to admit it. It can cause an immediate anxiety spiral. Scary thumbnails in Youtube videos can have the same effect, but at least there I can curate the feed to the point where they outright stop showing up. I cant do that with the TV.
Unfortunately, my father & stepmother are 100% addicted to the horrid thing, so it aint shutting off unless they arent here.
I've actually had the idea to get noise-cancelling headphones that I can use when I'm not in the basement, just to block that nonsense out.
Certainly better than taking a golfclub to the TV. I cant describe how much I hate that thing.
