I’ve just picked myself up off the concrete floor of this
basement. It’s cluttered, dimly lit, and smells of dust and bananas. Some of
the scattered items have been here as long as I’ve known the place—the ballerina
music box, the wedding dress, the journal—but I’ve recently made a few
additions of my own.
Welcome to my memory palace. It might not be what you expect.
It is not laid out very neatly, it is certainly not alphabetized, and it’s non-orientable
in Euclidean space. It is not a catalogue of tobacco
varieties or a repository
for trivia I could find far more quickly via Google search. My palace is a
collection of stories, symbols, music, and memories, steeped in meaning and
tangled up with reality and each other at every opportunity.
Don’t be startled by the emu. She’s just resting, hunkered
down on a luxurious velvet cushion, making little cooing sounds that go “orff,
orff, orff”. Another person’s mind can be uncomfortably alien, so I’ll
understand if you’re put off by the mannequin of myself with pointed ears who
stands nearby. If you make eye contact, she’ll turn inside out through her
mouth a few times before vomiting a small plastic 747. She means you no harm. Do
watch out for the slippery banana peel, smelling ripe and attracting fruit
flies, that’s always directly beneath the trap door. It gets me every time.
This little basement is where I store everything important I
learn about cognitive biases and heuristics that involve memory in ways
directly relevant to memory techniques. We’re looking for just such a bias, so
it’s bound to be here somewhere. I know because an elephant lowered his trunk
so we could climb down through the floor of the IU Credit Union. Elephants, you
see, never forget.
The banana’s definitely about humor, so that isn’t it. The
emu’s name is Von Restorff, which is closely related but not quite what I’m
after either. To the left of Von Restorff (velvet, resting, orff orff orff), I
spot something familiar. The meaning hasn’t resolved into full focus, yet it
feels right. There’s something round on the table, see it?, about two feet
tall. Ah yes, a ferris wheel! You can see colors now as it spins slowly in
place, sending quiet music drifting past as if from a great distance. Bend down
to listen. Carnival music? What is that about? What do I associate with
“carnival”?
Bazar! Of course. This is the bizarreness effect. It’s all
coming back to me.
To review the details, we’ll need to go one level deeper
into the imagined experience. We certainly can’t fit in one of those carriages
at our present size, so let’s shrink down and hop in. It’ll be just like
sticking your nose in a pensieve.
The basement room dissolves, and we’re at a carnival on the
4H Fairgrounds near my childhood home. The ragtime organ is bright and clear.
Tiny people down below lick oversized lollypops, and clowns hand out balloon
animals. The summer breeze is warm and smells like buttered popcorn, funnel
cakes, and livestock. You can feel the mechanical jerking of the carriage as we
rotate slowly toward the ground, where the operator lets us out.
The first thing we pass once safely on the ground is some
sort of acrobat. On a stage, he dances on his hands—only his hands—to the
carnival music, and I’m astonished at the complexity of the choreography and
the grace with which he executes it given the strange—I mean, the bizarre—constraint.
I simply must learn, so I ask for a lesson. You can too, if
you like. He obliges. He starts us out with the basics of balance, but I’m
eager to try his flashy spins and stranger stunts. Soon, he leaves us to
practice on our own. I remember the mechanics of the fancier stuff, but I can’t
actually perform any of it because I keep falling over. It’s terribly
frustrating, especially since I could tell during the lesson I’d likely forget
the basics. Straightforward though it seems, I can’t maintain a simple
handstand for more than a few seconds. That’s the bizarreness effect at work,
in one of its two guises: Boring things don’t tend to stick in memory.
When I go back to ask for a review of fundamentals, I find
that he’s teaching an entire class. They’ve been on handstands for quite a
while, it seems, and though a few people are still struggling, at least as many
are clearly getting bored. I’m struck by an idea for improving the class, and
pursue that rather than further instruction. I’ll be right back, promise.
When I was first learning logic, my professor would assign
problems she called “goats”. A “goat” is a problem that is much harder than
anything that might appear on a test. The idea is that anyone who tackles a
goat, whether or not she succeeds, will find the test refreshingly manageable.
The name came from a parable involving a goat, a rabbi, a large Jewish family,
and a shack that was far too small for them all. The story’s not important now,
but its appearance in a logic lecture seemed quite bizarre at the time, so I’ll
always remember it effortlessly. The other side of bizarreness: Weird shit’s
hard to forget.
There’s a petting zoo just one booth over from the stage, so
I borrow a goat and lead it to the hand-dancer. “Your students learn at
different rates,” I tell him, “and are motivated by different kinds of
challenges. Instead of having everyone do basic handstands over and over, you
could challenge the advanced students to do a handstand on this goat while it
trots around the fairgrounds.” He takes my advice, and soon the students up the
ante by doing handstands on each other atop the goat. (It’s a very strong goat
who doesn’t mind.) Thank goodness I remembered about the goat!
It’s getting dark and we should probably head back soon. The
ferris wheel is all lit up now, a brilliant reminder of our purpose here, so
let’s pause to review what we’ve learned. “The bizarreness effect,” I say to
you. “If you want to remember something, make it weird. But there’s a little
more to it, and it’s something more important. A use case we must always
recognize in real life.”
My trigger is a feeling of going in circles. Sometimes
information is very important, and I know it’s important, but it’s too mundane
to be memorable. You know the feeling. You grasp at the information and let it
repeat over and over in your mind, hoping mere repeated exposure will be enough
to make it last. But it keeps spinning and going nowhere, because your native
memory software just wasn’t made to learn boring things no matter how useful
they may turn out to be.
When I fail to employ the
knowledge stored at this carnival, I do nothing about that hopeless spinning,
and invariably I forget. But when I succeed, I engage with the important but boring
information in a genuinely memorable way—either by writing it down, or by
calling on my other memory skills. And I know that anytime I feel the pointless
spinning, I will be transported to this carnival, if only long enough to be
reminded to act.
As you see the resolution of my renewed
commitment to real-life application reflected on my face, the ferris wheel
escapes its hinges with a screeching battle cry. It rolls off, blazing
victoriously across the country side, actually getting somewhere for the first
time in its life.
_____________________________________________________
I imagine that sounds like a ridiculous amount of detail,
and therefore work, just to be reminded that boring things aren’t as memorable
as bizarre ones. It really doesn’t feel that way from the inside, though. Constructing
the carnival in the first place took some effort, but definitely not as much as
you imagine, for I follow algorithms that get ever easier with practice. If you
knew exactly what I was doing, the same thing might take you ten minutes.
When I walk through this sequence, either from the IU Credit
Union or directly from my trigger, it doesn’t happen in words. It’s more like a
holodeck movie on fast-forward. A sequence of this length takes ten seconds at
most. And the more often I play it, the more targeted become the details.
Before long I’ve distilled it down to a handful of powerful symbols—not by any
directed effort of my own, but just by the nature of remembering. So in
practice, it’s more like this:
Memory-weirdness? 404-search-Palace. Biases portal, trap door, search, found: wheel, bizarreness. Carnival sensations, hand-dancing-flashy-moves-falling-over. Logic-goats. Trigger: boring-things-spinning. Action: bother-to-remember-wheel-rolls-away.
The story also means a lot more to me than it does to you. I
chose handles for several abstract concepts out of my association network,
and picked examples that I cared about. For instance, I’ve watched dance
students retain the flashy stuff while neglecting the basics again and again,
and I’ve been frustrated with their resulting frustration. If you haven’t
grasped the boring fundamentals, all the crazy awesome moves in the world won’t
help you progress much as a dancer—but unfortunately, the flashy stuff is
easier to remember. So for the first guise of bizarreness, I chose a concrete
example with a strong emotional effect for me. And I did the same with my
example of the other guise. This is why no one can build your memory palace but
you.
