After covering the World Memory Championships as a journalist, Foer spends a year learning about the history of memory-training techniques, our understanding of how memory works, and training with some of the other competitors, before competing in the championships himself.
It’s difficult to imagine being more committed to a story about memory competitions. Does a good job of balancing personal memoir, coverage of the events and their competitors, and deep dives into the history of mnemonics and the current neurological and psychological studies. Gives an overview of techniques like memory palaces and mnemonic systems, along with explanations of why the location- and imagery-based techniques are more effective than rote memorization. Includes interviews with people with remarkable memories — either positive or negative — that are conducted with as much compassion as objective interest. Maintains an appropriate level of skepticism about his interview subjects and the entire endeavor as a whole.
Reads more like a collection of magazine articles than a cohesive book, which is great for spending time with a topic but not so great for pacing. Little practical information for learning the techniques yourself. Hints at larger practical benefits for all of the exercises that keep them from being just a stunt, but those passages are a little more vaguely hand-waving than the rest. Reading the book has made me less encouraged to try out any of the systems, since the thought of having to think of elaborate imagery to remember the name of a person I’ve just met, while they’re still talking to me and expecting me to respond, sounds more stressful than just admitting I’ve already forgotten their name.
Emphasizes some interesting ideas: that memory is more about indexing information than simply storing it, and the ways in which memory and intelligence are interconnected. (Remembering isn’t the same as learning, but it helps learning because it gives us more frames of reference to make incoming information more “sticky.”) But I was left feeling a little disappointed that none of it seems to have much real-world practical benefit.
