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.
