Memory
How your brain takes in, stores and finds memories, why forgetting is normal, and the techniques that make things stick.
Memory isn’t one thing. Holding a phone number for a few seconds, remembering where you parked, and knowing how to ride a bike all rely on different systems in the brain. Once you know how those systems work, a lot of everyday forgetting starts to make sense, and so do the techniques that fix it.
Start with how memory works for the overview, or working memory to understand why you can only juggle a few things at once. If you want to remember more, the spaced repetition and memory palace guides are the two most powerful techniques we know of, and both are backed by decades of research.

Frequently asked questions
What are the main types of memory?
Researchers usually separate sensory memory (a split second), short-term or working memory (a few seconds to a minute) and long-term memory (anything from hours to a lifetime). See short-term vs long-term memory.
Why do we forget things?
Mostly because memories that aren’t revisited fade, and similar memories interfere with each other. The forgetting curve shows how quickly that happens and how reviewing slows it down.
What is the fastest way to improve memory?
Pay full attention when you take something in, then test yourself on it at spaced intervals. Simple techniques like chunking help right away.
Is photographic memory real?
Not in the way films show it. A few children have unusually vivid visual memories, but there’s no good evidence for adults with true photographic recall. See is photographic memory real?
