We're running out of memory.
I don't mean computer memory. That stuff's half-price at Costco these days. No, I'm talking about human memory, stored by the gray matter inside our heads. According to recent research, we're remembering fewer and fewer basic facts these days.
This summer, neuroscientist Ian Robertson polled 3,000 people and found that the younger ones were less able than their elders to recall standard personal info. When Robertson asked his subjects to tell them a relative's birth date, 87 percent of respondents over age 50 could recite it, while less than 40 percent of those under 30 could do so. And when he asked them their own phone number, fully one-third of the youngsters drew a blank. They had to whip out their handsets to look it up.
That reflexive gesture — reaching into your pocket for the answer — tells the story in a nutshell. Mobile phones can store 500 numbers in their memory, so why would you bother trying to cram the same info into your own memory? Younger Americans today are the first generation to grow up with go-everywhere gadgets and services that exist specifically to remember things so that we don't have to: BlackBerrys, phones, thumb drives, Gmail.
I've long noticed this phenomenon in my own life. I can't remember a single friend's email address. Hell, sometimes I have to search my inbox to remember an associate's last name. Friends of mine space out on lunch dates unless Outlook pings them. And when it comes to cultural trivia — celebrity names, song lyrics — I've almost given up making an effort to remember anything, because I can instantly retrieve the information online.
