Is the Internet ruining our ability to remember facts? If you've ever lunged for your smartphone during a bar argument ("one-hit father of twerking pop star" — Billy Ray Cyrus!), then you've no doubt felt the nagging fear that your in-brain memory is slowly draining away. As even more fiendishly powerful search tools emerge — from IBM's Jeopardy!-playing Watson to the "predictive search" of Google Now — these worries are, let's face it, only going to grow.
So what's going on? Each time we reach for the
The short answer is: No. Machines aren't ruining our memory.
The longer answer: It's much, much weirder than that!
What's really happening is that we've begun to fit the machines into an age-old technique we evolved thousands of years ago — "transactive memory." That's the art of storing information in the people around us. We have begun to treat search engines, Evernote and
And frankly, our brains have always been terrible at remembering details. We're good at retaining the gist of the information we encounter. But the niggly, specific facts? Not so much.
