Why remember and why we forget. (Terry Gross; Fresh Air podcast)

When is forgetting normal — and when is it worrisome? A neuroscientist weighs in.

When cognitive neuroscientist Charan Ranganath meets someone for the first time, he's often asked, "Why am I so forgetful?" But Ranganath says he's more interested in what we remember, rather than the things we forget.

"We're not designed to carry tons and tons of junk with us. I don't know that anyone would want to remember every temporary password that they've ever had," he says. "I think what [the human brain is] designed for is to carry what we need and to deploy it rapidly when we need it."

Ranganath directs the Dynamic Memory Lab at the University of California, Davis, where he's a professor of psychology and neuroscience. In the new book, Why We Remember, he writes about the fundamental mechanisms of memory — and why memories often change over time.

Ranganath recently wrote an op-ed for The New York Times in which he reflected on President Biden's memory gaffes — and the role that memory plays in the current election cycle.

Recent gaffes by Biden and Trump may be signs of normal aging — or may be nothing.

"I'm just not in the position to say anything about the specifics of [either Biden or Trump's] memory problems," he says. "This is really more of an issue of people understanding what happens with aging. And, one of the nice things about writing this editorial is I got a lot of feedback from people who felt personally relieved by this because they're worried about their own memories."

After Coronavirus, Don’t Forget: Republicans Put Us in Danger

Here in the United States, both politicians and the public tend to have the shortest of short memories. There is much collective “forgetting” that goes on in Washington D.C., New York, and beyond. Consider those politicians and pundits who cheered on the illegal invasion of Iraq in 2003, while spreading lies about weapons of mass destruction, and continue to hold important and influential positions in politics and in the media; one of them is even on course to be the Democratic presidential nominee in November. Today, however, few mention Iraq in relation to any of these politicians or pundits.....
