Encoding: Making Things Stick in the First Place

This chapter covers the one universal skill under every memory technique: encoding information vividly enough to stick.

The Core Claim

The single biggest predictor of whether you'll remember something is how well you encoded it in the first place. Not how often you reviewed it. Not how long you stared at it. How well your brain was engaged when the information first came in.

Everything else in this tutorial (palaces, peg systems, spaced repetition) is machinery for encoding better or for protecting a good encoding from decay. Skip this chapter and nothing else sticks.

The Rules of Vivid Encoding

Five rules. They compound.

Make It Visual

The brain is wired for vision. Roughly a quarter of the cortex is devoted to it. Visual information gets preferential treatment; abstract or verbal information doesn't.

When you want to remember "gallon of milk", don't think "gallon of milk". See a gallon of milk. Sitting on the counter. Condensation on the side. The handle. The blue label.

Abstract words resist visualization. "Democracy", "freedom", "liberty" are hard to see. For those, use a concrete image that stands for the abstraction: Lady Liberty for "liberty", a ballot box for "democracy", a bird for "freedom".

Make It Weird

Ordinary scenes fade. Weird ones stick.

A gallon of milk on the counter is forgettable. A gallon of milk exploding in the microwave is memorable. A gallon of milk with tiny legs running across the counter is unforgettable.

Rule of thumb: if the image would be surprising on a security camera, it's probably vivid enough.

Make It Move

Static images are weaker than moving ones. A cheese wheel sitting on a couch is okay. A cheese wheel rolling across the couch and knocking over a lamp is much stronger.

Every encoded image should have a verb. Not "apple at the front door", but "apple wedged in the front door", "apple rolling down the hallway", "apple dripping juice onto the carpet".

Make It Multi-Sensory

You have five senses. Most people only use one when encoding. Add sound, smell, touch, and sometimes taste.

"A giant apple in the front door" is one sense. "A giant red apple wedged in the front door, sticky juice running down your hand when you touch it, smelling like your grandmother's pie" is four. The multi-sensory version is three or four times harder to forget.

You don't need all four every time. Two is noticeably better than one.

Make It Personal

Encode with things you already care about. Your kitchen, not a generic kitchen. Your friends, not stock photos. Your dog, not a dog.

Personal material has more existing hooks, which means more points of attachment for the new information.

The Baker/baker Paradox

Try this demonstration. You meet two people at a party. One is told "his name is Baker". The other is told "he is a baker". A week later, which do you remember better?

You'll reliably remember "he is a baker". The name Baker is an arbitrary label with nothing attached. The profession baker is connected to flour, ovens, bread, aprons, early mornings, and a hundred other hooks in memory.

This is the baker/baker paradox, demonstrated experimentally by Gillian Cohen in 1990. It shows that the issue isn't the word. It's what's attached to the word. The fix for "can't remember names" is to attach things to them (Chapter 8). The fix for "can't remember vocabulary" is the same (Chapter 9).

Elaboration

Elaboration is the process of connecting new information to things you already know. The more connections, the more retrieval paths.

Given "PostgreSQL was first released in 1996":

Shallow encoding: "PostgreSQL, 1996". Memorized by rote; forgotten in a day.

Elaborated: "1996 is the year I was born." Or "1996, that's the year Netscape IPO'd and Pokemon launched." Or "PostgreSQL is descended from Ingres, which was Stonebraker's Berkeley project; 1996 was the open-source release." Each connection is a new hook.

Elaboration is why understanding beats memorizing. When you understand a topic, every new fact connects to the structure you already have, so new facts stick easily. When you don't, facts float.

The practical move: when you learn a new thing, ask "what does this remind me of?" and say the answer out loud. That's free elaboration.

Concrete Over Abstract

The brain struggles with abstract concepts. It excels at concrete ones. Part of encoding well is translating abstract things into concrete images.

Concrete: "dog", "apple", "door", "hammer".

Abstract: "justice", "interest rate", "software", "happiness".

For the abstract ones, find a concrete proxy:

justice        a gavel
interest       a stack of coins
software       a floppy disk (or a more modern metaphor of your choice)
happiness      a smiley face
oxygen         bubbles in water
democracy      a ballot box
economy        a shopping cart
theory         a textbook

Your proxies can be personal and weird. They just need to be consistent (same image every time) and concrete (you can picture it).

An Encoding Drill

Here are ten items. Spend 30 seconds on each, encoding vividly with the five rules. Don't write anything down.

1. telephone
2. octopus
3. kettle
4. mountain
5. pencil
6. library
7. thunderstorm
8. astronaut
9. violin
10. pineapple

Now wait two minutes (scroll, read something else). Then try to list all ten from memory.

Most people, first try, get seven or eight. The two you miss were probably encoded flatly: you thought "telephone" without seeing one. The ones you got were vivid.

Do the drill every day for a week with ten new items. Your encoding will noticeably sharpen.

What "Paying Attention" Really Means

"Pay attention" is bad advice because it's vague. What you actually need to do:

  • Look at the thing. For 5 seconds. Eyes on it, not on your phone.
  • Name it silently. "Car keys. On the counter. Next to the salt."
  • Imagine them there. Three seconds of visualization.
  • Move on.

Twelve seconds. You will never forget where those car keys are.

The reason you "forgot where you put your keys" isn't a memory problem. You put them down while thinking about something else. You never encoded the scene. Memory can't retrieve what isn't there.

Common Pitfalls

Making boring images. "An apple on the table" is a boring image. "A squelching apple oozing across the table" is a vivid one. When in doubt, add action and exaggeration.

Same image for different items. "I picture a box for both 'database' and 'library'." Now the images collide. Make each image distinctive; use different proxies.

Trying to remember without encoding first. Reading a list and hoping it sticks. Always stop, picture each item vividly, and only move on when you can see it in your mind's eye.

Encoding silently. Saying the item out loud (or subvocalizing strongly) helps; completely silent reading is the weakest encoding.

Rushing. Encoding takes seconds per item. If you're doing a list of 20 items in under a minute, you're probably not encoding at all.
