Are you forgetful? That’s just your brain erasing useless memories
Most of us think “perfect” memory means never forgetting, but maybe forgetting actually helps us navigate a world that is random and ever-changing.
So say two neuroscientists in a review published today in the journal Neuron. The argument is that memory isn’t supposed to act like a video recorder, but instead like a list of useful rules that help us make better decisions, says study co-author Blake Richards, a University of Toronto professor who studies the theoretical links between artificial intelligence and neuroscience. So it makes sense that our brains would make us forget outdated, irrelevant information that might confuse us, or information that leads us astray.
