It's a testable hypothesis if you can get enough people to agree that their kids should be banned access to all such distractions (and such a ban to remain in place into adulthood). Obviously they'd still need access to electronically available information. Whether discussion forums/messaging apps count as distractions might be a grey area.
I honestly don't know what the result would be, or how long it would take to determine the outcome one way or another.
I mean, theoretically, yeah. You could do the test if you had some sort of absolute tyranny over people, a ton of money, about 1000 babies to otherwise do nothing else with, staff to raise those babies according to the experiment, and the 20-35 years of time to wait for the experiment to conclude. I'm sure I'm forgetting some crucial variable to control for though.
But that test is never going to be run. Nobody has that kind of time, that kind of money, that lack of morals, nor that energy to devote to this. There isn't a review board on the planet that would allow for this to occur, for good reason.
Agreed, it's not practical or particularly realistic - I don't think 1000 would be enough either. Maybe 50k? I'm not sure we'd like the results we might get either!
