A research done by Paul Frankland and Blake Richards from the University of Toronto shows that being forgetful can mean you are smart.
The study, which was published in the Neuron journal, elaborates that those who forget are able to make better decisions.
“It’s important that the brain forgets irrelevant details and instead focuses on the stuff that’s going to help make decisions in the real world,” one of the researchers, Mr Richards, said.
Therefore, the brain sometimes cannot remember details like phone numbers, names of people, birthday dates, or even something that a person just read.
According to the University of Toronto researchers, the brain knows there are systems in place to remember such as a phone book, which can save a large number of contacts.
The researchers said forgetting creates space in one’s brain to learn new things.
The survey revealed that the reason why people forget is that new brain cells grow in the brain (hippocampus) and overwrite old memories. Therefore, room is created to learn new things.
“If you’re someone who forgets the occasional detail, that’s probably a sign that your memory system is perfectly healthy and doing exactly what it should be doing,” Mr Richards says.
He however adds that “you don’t want to forget everything, and if you’re forgetting a lot more than normal that might be cause for concern.”
