From Julie Beck’s article on why we forget most of the books we read:

In the internet age, recall memory—the ability to spontaneously call information up in your mind—has become less necessary. It’s still good for bar trivia, or remembering your to-do list, but largely, Horvath says, what’s called recognition memory is more important. “So long as you know where that information is at and how to access it, then you don’t really need to recall it,” he says.

Research has shown that the internet functions as a sort of externalized memory. “When people expect to have future access to information, they have lower rates of recall of the information itself,” as one study puts it.
