Why We Forget Most of the Books We Read

Great overview of the “forgetting curve“, the way that we immediately forget almost all the information we take in:

For many, the experience of consuming culture is like filling up a bathtub, soaking in it, and then watching the water run down the drain. It might leave a film in the tub, but the rest is gone.

That describes many of my reading experiences quite well; sometimes I feel like the characters in this Portlandia skit. The key to avoiding this is recalling and re-encountering the information again:

If you want to remember the things you watch and read, space them out…Memories get reinforced the more you recall them, Horvath says. If you read a book all in one stretch—on an airplane, say—you’re just holding the story in your working memory that whole time. “You’re never actually reaccessing it,” he says.

The most well-known technique for recalling information systematically is spaced repetition:

Spaced repetition is a learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect.

This website has always served as my outboard brain, but I don’t re-encounter my own thoughts on a regular basis. I’ve tried a few times to set up a system to send me random past posts; worth getting that going.
