If you've ever forgotten something and felt really awkward about it, or unsure of yourself, relax. Forgetfulness is a sign of higher intelligence, according to recent studies. You might wonder why these minor brain lapses occur, but you don’t really need to worry. Researchers Paul Frankland and Blake Richards from the University of Toronto found that old memories in the brain are literally “overwritten” by new memories. It is basically harder for us to remember the old impressions – or forget them completely. According to the study, a perfect memory isn’t connected to high intelligence in any way. In fact, the study found that the opposite tends to be true. While you might assume that someone with a great memory is generally considered intelligent, it is actually more useful and even healthier to remember a larger scale of everything and forget small details.
