Arguably the only ethical way of removing external social conditioning might be to find a regional social setting which lacks that specific element in order to evaluate the statistical impact by comparing results that should be similar between the two environments.
There're tradeoffs, pros and cons to social media and gaming, but framing it in an addiction narrative isn't helping matters. This is what led many Chinese people to put their kids in "camps" that used Electro Convulsive Therapy to "fix their internet addiction". This is born of ignorance, and the addiction narrative.
I think elements can be intuited, and more studies done, but when you're bashing the cheapest forms of entertainment and social contact, and safest to boot, as addictions... that's just ignorant.
What?
You don’t allow your kid to go outside or hang out with friends face to face? You prefer his/her social interactions are all intermediated by a computer network? This seems like a very strange and dystopian preference.
Do you actually have a kid or is this hypothetical?
If you do think that this study proves a genetic difference between how men and women, then one of us is wrong about what an experiment like this can "prove". (I don't think it's quite "correlation != causation", but it's along those lines; I don't have the vocabulary to precisely say why I think that position is wrong.) If that is your position, then maybe this one counterexample will be enough to change your view; it should be, even though that was never my intent. Maybe I've drastically misread your comment and you don't believe anything of the sort. If so, I'm sorry.
What if we asked whether this study "supports" such a difference instead of "proves" it? Would you still say you know it doesn't support it?
The point is that it illustrates the study may not have taken such considerations into account. It calls to question the accuracy and efficacy of their results.
If the target domain is incredibly complex with major fundamental unknowns, then even robust results should not be viewed as 100% definitive.
If the concept is not obvious, the onus is even more on the person bringing it up. Otherwise we'd still have physics running on phlogiston, and medicine on leeches as everyone explored irrelevant ideas.
The problem is that the probability to finding a "gaming" gene, one that only exist or be expressed in males, would be very unlikely.
Robert Sapolsky has a good description of this in his lecture series "Human Behavioral Biology" (https://www.youtube.com/watch?v=NNnIGh9g6fA&list=PL848F2368C...).
It's tough to make an intuitive story for why RCTs are important, so the story sounds elaborate. You don't need to offer evidence against the theory to say that the methodology is weak.
Anyways, wet streets might cause rain.
And how do you produce a social placebo to detect such effects by comparison? No treatment is not the same as known fake treatment.
In fact, even the observational study here is quite underpowered and not multicultural. It is to be taken with a few bags of salt.
If a hypothesis leads you to test for something and collect (dis)confirming evidence, And your argument hinges on the evidence, then we aren’t arguing from ignorance.
A good argument against a study's methodology would probably talk a lot more about the methodology, and a lot less about a believable alternative narrative that is supported by the study. The latter strategy is accepting of the methodology because it is granting that the observed effect is real and deserving of explanation. In a different light, the earlier comment ("As an example of how the observed differences could still be due to nurture rather than nature...") is kind of weird because it is as though the effect might as well be due to nature -- it would present the same way and be as consistent and robust -- even if it were due to socialisation.
I was particularly interested in the participant selection section; they did go to an effort to select male and female participants with similar gaming habits. However, this doesn't mean that the only explanation for the different "craving" response is a fundamental difference between men and women. Just because you end up with a similar population with similar habits, doesn't mean that the path those individuals traveled to get there is the same.
As an example of how the observed differences could still be due to nurture rather than nature, suppose that across all young boys and girls, there is a subset of people that are predisposed to addiction. Also suppose that in many cases, an addiction can begin the first time you're exposed to something. Even if both boys and girls were equally predisposed to become addicted to both video games and social media, they would not be equally likely to be exposed to those two addictive digital activities. It would be more likely that a boy's friends would introduce him to video games, and that a girl's friends would introduce her to social media. Once they are addicted to one or the other, they will spend more time on that activity, and will be unlikely to explore the opposite.
Eventually, these hypothetical boys and girls grow up, and our hypothetical scientists select participants for their version of this fMRI experiment. They do a good job selecting male and female participants who play games for similar numbers of hours, but the potential female video game addicts in this universe are much less likely to ever start playing games, before getting addicted to something else. Since these hypothetical people have selected themselves out of this hypothetical study, they discover a difference in fMRI responses to images of video games that's correlated with gender, but still 100% caused by existing gender roles and stereotypes.
