“Even though our lives wander, our memories remain in one place”*…
Your correspondent’s fascination with the “memory palace,” the age-old technique of memorization, has shown up in (R)D many times before (e.g., here, here, here, here, here, and here :) That it works has been long understood– but how it works, not so much. Ingrid Wickelgren reports on research that may offer a clue…
After shuffling the cards in a standard 52-card deck, Alex Mullen, a three-time world memory champion, can memorize their order in under 20 seconds. As he flips though the cards, he takes a mental walk through a house. At each point in his journey — the mailbox, front door, staircase and so on — he attaches a card. To recall the cards, he relives the trip.
This technique, called “method of loci” or “memory palace,” is effective because it mirrors the way the brain naturally constructs narrative memories: Mullen’s memory for the card order is built on the scaffold of a familiar journey. We all do something similar every day, as we use familiar sequences of events, such as the repeated steps that unfold during a meal at a restaurant or a trip through the airport, as a home for specific details — an exceptional appetizer or an object flagged at security. The general narrative makes the noteworthy features easier to recall later.
“You are taking these details and connecting them to this prior knowledge,” said Christopher Baldassano, a cognitive neuroscientist at Columbia University. “We think this is how you create your autobiographical memories.”
Psychologists empirically introduced this theory some 50 years ago, but proof of such scaffolds in the brain was missing. Then, in 2018, Baldassano found it: neural fingerprints of narrative experience, derived from brain scans, that replay sequentially during standard life events. He believes that the brain builds a rich library of scripts for expected scenarios — restaurant or airport, business deal or marriage proposal — over a person’s lifetime.
These standardized scripts, and departures from them, influence how and how well we remember specific instances of these event types, his lab has found. And recently, in a paper published in Current Biology in fall 2024, they showed that individuals can select a dominant script for a complex, real-world event — for example, while watching a marriage proposal in a restaurant, we might opt, subconsciously, for either a proposal or a restaurant script — which determines what details we remember…

As we remember (and lest we forget), we might recall that it was on this date in 1920 that Adolf Hitler, the propaganda head of the German Worker’s Party (DAP) gave a speech (now known as “Hitler’s Hofbräuhaus speech”) to 2,000 followers at a Munich beer hall announcing the change in the party’s name to the Nationalsozialistische Deutsche Arbeiterpartei (“National Socialist German Workers’ Party”, or Nazi Party). It was then that the party officially announced that only persons of “pure Aryan descent” could become members and that their spouses had to be “racially pure” as well.
Oh, and on this date in 1868, an American President (Andrew Johnson) was impeached for the first time.
