This might seem like a bit of a cheap dig, but let's have a look into the facts and figures of this study - which we're sure was exhaustive and scientifically rigorous, of course - to see what they actually did.
Well, they took 1,001 gamers and gave them all a test to assess their cognitive skills. That test looked at four particular areas that are key indicators of intelligence.
They looked at the participants' verbal intelligence, mathematical ability, visual reasoning and logical reasoning to build up a profile of their overall intellect.
Before they took these tests, the gamers were asked about their gaming habits. The data from all the answers and results were compared together to establish the IQ levels for players of both different consoles - and players of specific games.
It found that Xbox users simply aren't as smart as PlayStation users.
OK, so it's only a small sample size, and the results are not exactly what you'd call scientifically conclusive, but let's indulge them for a little longer, shall we?
As any PC gamer will tell you, it turns out that PC users are in fact the smartest of the whole bunch.
They averaged an IQ of 112.3, whereas PlayStation gamers - in second place - averaged 110.7.
In third, there were Xbox users with an average IQ score of 103.8.
Lagging behind them were users of the Nintendo Switch (101.3) and finally mobile device gamers (99.4).
Make of that what you will.
In terms of the games that are played by the smartest - as far as this study goes anyway - Rainbow Six Siege gamers came top with an IQ score of 120.3, whereas Among Us players ranked at 118.9 IQ points.
Minecraft enthusiasts were down at 116.3 - which is still respectable - and Call of Duty: Modern Warfare players had an average IQ of 111.2.
Rounding out the top five - and this is surely the most shocking statistic of all - were the FIFA heads, with an average IQ of 106.5.
Again, that's just the results of this particular study. If you want different results, you can presumably run your own 1,000+ person test.
Anyway, even further below FIFA players were those who play Candy Crush Saga (96.4) and Angry Birds (95.8).
