How to get smarter in six achievable, science-backed steps
There is no convincing evidence that brain-training apps can make you smarter.
However, one line of enquiry has compared brain-training games to run-of-the-mill video games, and this is where things get interesting. In a 2015 study comparing the brain-training game Lumosity with the first-person puzzle game Portal 2, researchers found that Lumosity players didn’t show boosts in problem-solving and spatial skills, but Portal 2 players did.
More recently, in 2020, researchers based at the Karolinska Institutet in Sweden looked at data from some 9,000 American children and found that kids aged 9 or 10 who played video games for above-average amounts of time didn’t show any differences in intelligence compared with those who played less.
