"At baseline, time watching and socializing were negatively correlated with intelligence, while gaming did not correlate. After two years, gaming positively impacted intelligence, but socializing had no effect. This is consistent with cognitive benefits documented in experimental studies on video gaming."
> Following the steps of a previous study with this same dataset (measuring baseline associations only [13]), we categorized screen time here into three major groups: (a) Watching (1 + 2), (b) Socializing (4 + 5 + 6), (c) Gaming (3).
So that's why they described it as " ocial media, text, and video chat". Their data comes from the ABCD study. I didn't look much further. https://abcdstudy.org/
Do you have a source for that? Happiness I can believe, especially because of the correlation between intelligence and neuroticism, but if IQ is a valid proxy for intelligence then I think the consensus is that intelligence strongly correlates with success.
High IQ people are also thought to be prone to ambition, questioning for purpose and stricter yearning at any achievement level which leaves them perennially unsatisfied
So it's confirmed? Gaming > Socializing? /s
