If you’re a parent, you can smell about 90% of your kids’ lies, right? And if you’re a kid, you’d say that, in reality, it’s more like 9%. But this trick MIGHT be able to boost lie-detecting prowess.
Researchers in the U.K. have found that liars who have to MULTITASK are much easier to expose. The idea is that lying requires more mental energy than telling the truth . . . so giving someone an additional, unrelated task to think about makes it more of a struggle to maintain a lie.
The researchers told people to remember a “very important” seven-digit number. And if liars had to keep that number in their head, their lies sounded less plausible than when they weren’t distracted.
