Does forgetting make us smarter?


Researcher­s at the University of Toronto have found that the inability to remember isn’t necessaril­y a sign of mental weakness. Blake Richards and Paul Frankland say our brains actively work to forget unimportan­t informatio­n. Richards explains: “The brain forgets irrelevant details to aid good decision-making. If we did not forget, our brains would become overwhelme­d by banalities, so forgetting keeps the brain in shape.”
