If you have a memory like a goldfish (aka. me), then you need to read this !
The Research.
Scientists at the University of Toronto, in Canada, have released some interesting research that claims that people with poor, short-term memory might actually be smarter than those "brains-in-jars" that remember everything.
Your skills of recall might not be the best, this might be a sign that your brain is creating space for new info rather than retaining the things that don't matter.
They found that the growth of neurons in the hippo-campus (the part of the brain that deals with memory) actually promoted forgetting, with the purpose of making room for more important details while discarding useless info.
Why We Forget.
We always praise a person who can smash a trivia game, but the point of memory is not being able to remember who won a sports game in the 1970s. The purpose of memory is to make us intelligent, so that we can make decisions given the circumstances, and an important aspect in helping us do that is being able to forget some of the things we don't need.
They did an experiment on mice that showed that the tested animals could find the exit from a maze quicker when they were drugged to forget where it had been previously and discovered it, rather than those who were not drugged and used previously known information to find their way out.
Personally
I've experienced this weird phenomena where I had forgotten parts to a movie that I had watched quite a few times before-King Kong(The 2005 Peter Jackson King Kong). I had sat down and started watching the movie, and for some reason, there were parts to the movie that I can't, for the life of me, remember. I was quite young the last time I had watched the movie, but whenever I watched movies and watch them again, I can always remember the scenes, more or less, but this time, I had no memory of a lot of the scenes. So maybe my brain decided to chuck some of the memories from back when I watched the movie ?
Conclusion
It was concluded that without any new research, but found enough evidence that forgetting promotes brain activity and can be very useful.
It does make some sense. When your brain is full of information that we don't use - old passwords, for example - it struggles to remember a new, useful one. We remember the most important points rather than the specifics for exactly this reason. We went to the shops, rather than the exact details of what we bought. That's why you can remember a song and an artist rather than the whole lyrics. And also why you should avoid quizzes that want you to know the whole lyrics to 'Wonderwall'. Actually, maybe or maybe not... I forgot.
