Researchers Discover Amazing Trick for Raising Your IQ

Can brain-training games increase your IQ? Some studies suggest they can, but a group of George Mason psychologists were suspicious. Maybe IQs increased only because participants knew they were engaging in a study of intelligence, with the placebo effect doing all the heavy lifting. To test this, the GMU researchers recruited two different groups of students: one was told they were participating in a brain-training study, while the other was told it was just “a study.” Brian Resnick tells us what happened:

The researchers had 25 participants in each group. They then tested their fluid intelligence, had them play a memory training game for one hour, and then tested their intelligence again.

It’s important to note that there’s absolutely no reason one hour of training should make any reasonable difference when it comes to enhancing IQ. But amazingly, the placebo group’s IQ jumped, while the other group’s IQ remained flat….The placebo group grew “smarter” because they expected to grow smarter. (Perhaps they were more focused and concentrated on the tests, which increased their scores. It’s also evidence for how important motivation can be for cognitive performance.)

The conclusion is that brain-training games don’t really do anything to increase intelligence and that brain-training research should be rigorous. But that sure seems like it’s burying the lead. If this research is reliable, it tells us that a mere expectation of brain training will increase your IQ by a whopping five points. And I don’t mean “whopping” in a sarcastic sense, either. An IQ of 100 means you’re smarter than half the population. Raising that to 105 makes you smarter than 63 percent of the population. All that from mere expectations.

Sadly, the research probably isn’t reliable. It’s based on two groups of 25 students. I’ll bet ten dollars that it doesn’t replicate if someone else tries it.

But I’d sure like to see someone try to replicate it. If it pans out, we’ve just discovered the easiest way ever to increase IQs.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
