Attempting to recall information before being shown the answer — even when you get it wrong — produces better long-term memory than passively reviewing the material.

Huberman presses Castel on whether encoding names by pairing them with unrelated cues is actually efficient — after all, you're adding information to remember more information. Castel concedes it's a workaround: names used to be occupational descriptors (Mr. Baker really was a baker), but that semantic hook has eroded over time. His real answer is levels of processing: the deeper and more meaningfully you encode information — thinking about chemistry in terms of how elements react rather than what they're called — the stronger the memory trace. This principle, he argues, is why psychology hooked him and chemistry didn't: psychology was something he was literally living every day, while chemistry felt abstract. The section closes with a practical reassurance: if you can't recall someone's name, you've likely retained the more useful information anyway — how the conversation felt, whether they seemed reliable.
