Moonwalking with Einstein: The Art and Science of Remembering Everything is the account of that year, and it might be the most honest self-improvement narrative written in the last two decades. Not because everything works exactly as advertised — Foer is careful to note that winning a memory championship did not stop him from forgetting where he left his keys — but because it sits with a genuinely uncomfortable question: if the cognitive capacities we treat as fixed limits are actually ceilings nobody ever tried to raise, what else have we been wrong about ourselves? Extrapolated carefully from memory research and expertise science, the answer is: quite a lot.
Bottom Line on Moonwalking with Einstein
Moonwalking with Einstein is a genuinely excellent book — rigorous, funny, self-aware, populated with ideas that reach far beyond competitive memorization. It’s the rare popular science book that uses a journalist’s own experience as a real analytical instrument rather than a storytelling prop. Foer doesn’t just describe the techniques. He traces what happened to him, cognitively and psychologically, as he trained — the plateaus, the frustration, the unexpected revelations about intelligence and expertise that showed up along the way.
The first half — the history of memory, the ancient techniques, the neuroscience of encoding and retrieval — is about as good as popular science writing gets. The second half, Foer’s own training arc and competition run, is less consistently gripping but honest in a way most self-improvement narratives simply aren’t. He doesn’t oversell the results. He wins the championship and then spends the last pages questioning what he actually learned, what transferred to ordinary life, and what was essentially just sport — impressive inside its own rules, not infinitely extensible beyond them.
The honest caveat here: competitive memorization is a highly specific skill domain. The memory palace technique dramatically improves performance on exactly the kind of information it’s optimized for — ordered sequences, arbitrary associations, numbers, names and faces. Its transfer to the messier, more conceptual, more relational kinds of memory that matter most for deep learning is less direct than the book sometimes implies. Foer gestures at this. The careful reader should take the gesture seriously. Use the techniques for what they’re actually built for, apply the underlying principles where they genuinely transfer, and don’t mistake championship performance for general cognitive transformation.
Cold Open: The Window That Changed a Memory Champion
Ed Cooke is one of Britain’s most accomplished competitive mnemonists, a Grand Master of Memory who’d spent years training his recall to a level most people would call impossible. He agreed to coach Foer through the year, and the two of them developed an odd sort of working relationship — part coach and athlete, part intellectual sparring partners investigating what memory even is.
Early on, Foer asked Cooke a question that sounded naive and turned out to be the real inquiry of the whole book. What’s the point? You can memorize a shuffled deck of cards. You’ve competed at the highest level of memory competition that exists. Does any of it make you actually smarter? Does it transfer to what you actually want to do with your life — your writing, your thinking, your understanding of anything?
Cooke’s answer — worked out over many conversations across the book — is the thesis of Moonwalking with Einstein, stated in its most honest and qualified form. The competitive skills themselves don’t transfer widely. Not that one. But investigating those skills illuminates something real about how memory works, how learning works, and what memory and thought actually have to do with each other. The ancient teachers who developed the memory arts weren’t building party tricks. They were operating on a belief — one cognitive science now supports — that a well-trained, richly structured memory is the foundation of all higher cognitive performance. The party tricks are what survived, because they’re demonstrable. The deeper argument got lost somewhere along the way.
The Ancient Art: Why the Greeks Built Memory Palaces
The memory palace — the method of loci, the technique at the heart of Moonwalking with Einstein — is credited to the Greek lyric poet Simonides of Ceos. The story, preserved across multiple ancient sources, goes like this: around 477 BC, Simonides performed at a banquet. He stepped outside briefly to take a message, and while he was gone, the building collapsed and killed everyone inside. The bodies were crushed badly enough that identification looked impossible. Simonides managed it anyway, because he could mentally walk through the room and recall exactly where each guest had been sitting. The insight he pulled from that experience became the foundation of the entire Western memory tradition.
Spatial memory — the ability to recall the layout of environments, to work through mentally through familiar places — is one of the oldest and strongest memory systems the human brain runs. The hippocampus, the structure most critical for forming new memories, evolved largely to support spatial navigation. “Place cells” in the hippocampus fire when an organism occupies a specific physical location. “Grid cells” in the entorhinal cortex build a coordinate system for mapping space. The whole system is ancient, biologically expensive, and highly resistant to interference and forgetting, because navigational memory was survival-critical for our ancestors in a way that remembering arbitrary lists never was.
Simonides’ insight was to use that spatial system as scaffolding for arbitrary information. Walk mentally through a familiar space, deposit vivid and unusual images at specific points along the route, and you can retrieve the information later by retracing the route and running into the images in order. The Greeks and Romans called it the “method of loci” — method of places — and refined it over centuries into a fairly sophisticated practice. It wasn’t a party trick in antiquity. It was how orators memorized hours-long speeches, how lawyers memorized entire cases, how philosophers memorized treatises, how educated men in a world before the printing press kept the intellectual libraries their work actually depended on.
The printing press changed all that. Once external memory — books, written records, indexed references — got cheap and widely available, the old argument that memory training underpinned thought itself got slowly set aside. The techniques survived in fragments: magicians’ guidebooks, the eccentric practices of competitors at the mental Olympics of Renaissance Europe. By the twentieth century they’d all but vanished from mainstream education. What Foer found when he showed up at the memory championship was a community that had quietly preserved and refined the ancient techniques — and that what those techniques could do to an ordinary person’s memory was, genuinely, extraordinary.
“Before the printing press, educated men memorized entire books. They didn’t have filing systems — they had memory palaces. The intellectual tradition they built was carried in their minds, not their libraries. When external storage became cheap, we outsourced our memory and forgot the techniques for building memory. We also, Foer argues, forgot something about what memory is actually for.”
The Neuroscience: Why the Method of Loci Works
- Spatial memory is our most strong system. The hippocampus evolved primarily for spatial navigation, and the spatial memory system is correspondingly strong — resistant to forgetting, easily retrievable, highly organized. Using a memory palace means attaching new information to a system millions of years of evolution optimized for durability. The information rides along on the retrieval architecture of a system built for exactly this: precise, ordered, reliable recall of spatially organized information.
- Episodic memory beats semantic memory. Semantic memory stores facts and concepts in isolation — Paris is the capital of France, the mitochondria is the powerhouse of the cell. Episodic memory stores personally experienced events, wrapped in spatial, temporal, emotional, and sensory context. It’s more durable and more reliably retrievable than semantic memory, because it comes encoded with multiple contextual cues, each one its own retrieval pathway. The memory palace converts semantic information into episodic form — it becomes embedded in a personally navigated spatial story, with all the contextual richness episodic encoding provides. That conversion is what produces the dramatic jump in retention.
- Emotion and bizarreness enhance encoding. The amygdala interacts with the hippocampus during memory formation to flag emotionally significant events for enhanced encoding. Evolution predicts this: dangerous things, sexually relevant things, socially significant things, novel things — these all mattered more for survival than neutral information, and got remembered more reliably as a result. The memory palace technique exploits this directly by encoding information as bizarre, funny, gross, violent, or sexually suggestive images — the more extreme and unusual, the better. That’s not an accident of the technique. It’s neurological engineering. You’re feeding the memory system exactly the signal it evolved to prioritize.
- Multi-sensory encoding creates more retrieval pathways. Information encoded across multiple sensory channels — visual, auditory, kinesthetic, olfactory — sticks better than information run through a single channel. Skilled practitioners of the memory palace technique don’t just use visual images. They layer in vivid sensory detail: the smell of the room, the texture of the objects, the sounds tied to the images. Every added sensory channel becomes another retrieval pathway, and any one of them can lead you back to the full encoding.
OK Plateau: The Ceiling That Practice Alone Won’t Break
One of the most practically useful ideas in Moonwalking with Einstein has nothing to do with memory specifically. It’s the “OK Plateau” — the point where a regularly practiced skill hits acceptable automaticity and simply stops improving. Foer’s go-to example is typing: most adults type at roughly the same speed they typed at twenty-two, despite decades of daily use. The skill has gone automatic, the brain has filed it away as background processing, and ordinary practice — just doing the thing over and over — no longer moves the needle.
The OK Plateau is where most people live with most of the skills that actually matter to them. Competent. Good enough to function. Stuck at that level for years, sometimes decades, without meaningful improvement. This isn’t laziness. Automaticity is the natural, appropriate endpoint of early learning — you want skills to become automatic so cognitive resources free up for higher-level functions. The trouble starts when automaticity gets mistaken for mastery, and ordinary practice gets assumed to be producing ongoing improvement when it’s actually just maintaining a ceiling.
The fix — identified by Ericsson, illustrated by Foer, and consistent across every domain of expertise research anyone’s bothered to check — is to deliberately break automaticity by pulling specific elements of the skill back under conscious control and practicing them with focused attention on the gap between where you are and where you want to be. The typing example: researchers told skilled typists to slow way down, on purpose, forcing the skill back out of automatic execution and into conscious attention. Performance jumped.
The slowdown created exactly the deliberate attentiveness automaticity had quietly eliminated.
Translated to memory: most people practice “normal use” memory — they go about their lives, things stick or they don’t, and whatever sticks gets accepted as “their memory” while everything else gets written off as forgetting. The memory palace competitors practiced differently. They deliberately encoded information using techniques that demanded conscious attention during encoding, tested their own retention regularly, and systematically pushed against the ceiling of what they could hold and retrieve. The same principle that produces expertise in chess, surgery, music, and athletic performance — deliberate practice aimed squarely at the ceiling — produces expertise in memory too. The OK Plateau isn’t a natural limit. It’s just the plateau ordinary, undeliberate practice produces, and mistakes for a limit.
The Proprietary Framework: The SPACE System for Durable Memory
Out of Foer’s investigation of the ancient memory arts, the neuroscience of encoding, and the practices of competitive memorists, a coherent framework emerges — one that applies to any situation where durable retention matters, not just the memory palace technique specifically. This is the set of neurological requirements for memory formation the memory palace optimally satisfies, and that apply, in varying degrees, to all effective encoding.
- S — Spatial Grounding. Attach information to physical locations, whether that’s a formal memory palace or just the simple act of noticing where you are and what you’re doing while you encode something. Spatial memory is the brain’s most durable filing system. Using it on purpose — even imperfectly — beats purely abstract encoding. For ordered lists and sequences, a formal memory palace is worth the effort of building. For everyday information, simply attending consciously to your spatial and environmental context during encoding creates retrieval cues that noticeably improve recall.
- P — Personal and Bizarre Imagery. Convert abstract information into concrete, vivid, personally resonant, or bizarre images before encoding it. The brain prioritizes unusual information over neutral information, full stop. The conversion from abstract — a name, a number, a concept — into concrete and bizarre — a specific, unusual, emotionally resonant scene — takes seconds and produces dramatically better retention. The more personal the imagery, the more it connects to things you already care about or find funny or find disturbing, the better it sticks.
- A — Active Retrieval, Not Passive Review. The single most important, and most consistently ignored, finding in memory research: retrieving a memory strengthens it more than reviewing it does. After learning anything worth keeping, close the source and actively recall everything you can. Test yourself. Write down what you remember without peeking. The effort of retrieval — including the partial forgetting and reconstruction that comes with it — is the actual mechanism behind lasting memory. Re-reading material is far less effective than testing yourself on it, even when the test reveals significant forgetting. Especially when it does.
- C — Contextual Elaboration. Information sticks better when it’s encoded with rich connections — to existing knowledge, personal experience, related concepts, sensory context. Every connection formed between new information and what you already know builds an additional retrieval pathway and embeds the new material more deeply into your existing knowledge network. Don’t just store facts. Ask how they connect to what you already know, what they explain, what explains them, why they matter. The understanding elaborative encoding produces isn’t separate from the memory it creates. It’s the same event.
- E — Extended Spacing with Retrieval Attempts. Distribute practice, with retrieval attempts, at increasing intervals rather than cramming review into a single sitting. The spacing effect — distributed practice beating massed practice for long-term retention — is one of the strongest findings in the field. The mechanism is what Robert Bjork calls “desirable difficulty”: slight forgetting between attempts forces the memory to be reconstructed, and that reconstruction builds the trace more durably than reviewing something while it’s still fresh and requires no real effort. Roughly optimal spacing: one day, three days, one week, two weeks, one month, recurring after that. Spaced repetition software — Anki, Remnote — automates this protocol for fact-based learning.
These five principles aren’t memory-palace-specific. They’re the underlying neurological requirements for durable memory formation, which the memory palace happens to satisfy exceptionally well but which apply to any learning situation whatsoever. The memory palace is the ancient engineers’ answer for encoding arbitrary, unstructured information. SPACE is the framework for encoding anything at all.
Memory and Understanding: The Argument the Ancients Were Making
The most philosophically loaded thread running through Moonwalking with Einstein is Foer’s investigation of what the ancient memory tradition actually believed memory was for — and his argument that modern education’s dismissal of memory training, in favor of “critical thinking” and “conceptual understanding,” rests on a false dichotomy that cognitive science flatly doesn’t support.
Foer interviews scholars of classical rhetoric and medieval education, and what falls out is striking: the ancient teachers didn’t draw a sharp line between memory and thought. The ars memorativa — the art of memory — wasn’t a filing system for facts in their eyes. It was the foundation of all higher cognitive function. Memory was the database of the mind. You can’t think with knowledge you can’t access. You can’t reason about a problem whose component parts you’ve never internalized. You can’t be genuinely creative in a domain until its vocabulary, patterns, and history are encoded deeply enough to be available effortlessly for recombination.
The modern dismissal of rote memory in progressive education — don’t memorize facts, learn to think critically — rests on an implicit assumption that critical thinking can run independently of a rich base of internalized knowledge. That assumption is empirically wrong. Daniel Willingham at the University of Virginia has combed this literature exhaustively: the cognitive science consistently shows critical thinking is domain-specific, and thinking critically about a domain requires extensive factual knowledge in that domain, encoded in long-term memory. You can’t think critically about history without knowing a lot of history. You can’t problem-solve in mathematics without having automated the foundational operations so thoroughly they demand no working memory at all. Background knowledge isn’t the alternative to critical thinking. It’s the prerequisite.
Foer’s own year of memory training demonstrated this personally. As his encoding techniques sharpened, he became aware of just how much of what he read and heard he was actually retaining — and how much had simply been sliding off without a trace before. The problem wasn’t reading comprehension. It was an encoding habit of passively receiving information without doing the work of connecting it to existing knowledge, encoding it in retrievable form, or deliberately retrieving it to strengthen the trace. Most educated adults read a lot and retain very little of it — not because they’re unintelligent, but because they’ve never built an active encoding practice.
The practical implication lines up with what every serious study of expertise has found: building an extensive, well-organized base of internalized knowledge in a domain isn’t the opposite of original, creative thinking in that domain. It’s the prerequisite for it. The composer with the most original voice is usually the one with the deepest knowledge of the tradition. The scientist who makes the unexpected connection is usually the one carrying the broadest encoded base of domain knowledge. Memory and intelligence don’t trade off against each other. They feed each other.
Expert Memory Architecture: How Masters Store Information Differently
The classic demonstration is chess. Shown board positions from real games for five seconds, chess grandmasters can reconstruct them with near-perfect accuracy — recall that looks like it requires supernatural memory or photographic processing. Shown randomly arranged pieces — positions that couldn’t occur in an actual game — grandmasters perform barely better than beginners. The expert advantage evaporates entirely the moment the information violates the meaningful patterns expert memory is organized around. This isn’t photographic memory. It’s expert schema activation. The grandmaster isn’t storing individual piece locations. They’re recognizing meaningful configurations — patterns of board positions that encode tactical and strategic content — and storing those configurations as unified chunks. Five seconds is enough to activate pattern recognition for a real position. It’s nowhere near enough for a random configuration that can’t be assimilated into any meaningful schema at all.
This finding — replicated across chess, radiology, computer programming, music — reveals something real about what expertise actually is. Expert performance in complex domains isn’t primarily about superior processing speed or raw memory capacity. It’s about the richness and organization of the pattern library that years of domain-specific experience have built. The expert radiologist doesn’t see more pixels. They see more meaningful configurations, because their library of pattern templates is deeper. The expert chess player doesn’t calculate more moves ahead. They recognize meaningful configurations that narrow the relevant search space and point attention at the positions that actually matter.
The memory palace technique addresses a specific slice of this bigger picture: it provides a spatial scaffold for arbitrary information that has no inherent meaningful structure of its own. Names and faces, card orders, digit sequences — these are informationally random from the memory system’s point of view, which is exactly why ordinary memory handles them so poorly. The memory palace supplies the structure that converts arbitrary information into the spatially grounded, episodic form memory actually handles well. For domain knowledge — for the pattern libraries expertise depends on — the right architecture is the schema-building that genuine, sustained engagement with a domain’s real patterns produces over years of deliberate practice. The memory palace is the tool for information with no inherent structure. Expert schema development is the tool for information that has plenty. Both matter. Neither substitutes for the other.
What Competitive Memorization Reveals About Intelligence
Foer’s year as a competitive mnemonist raises a question he never fully resolves, but one worth sitting with anyway: if remarkable memory performance is a learnable skill rather than an innate capacity, what does that suggest about intelligence more broadly? The popular conception treats intelligence as roughly fixed — something you have more or less of, something that shows up consistently across domains, something cognitive tests can measure with reasonable accuracy. The memory championship experience suggests a more unsettling picture than that.
The competitors Foer trained alongside weren’t uniformly high-IQ people with exceptional general cognitive ability. They were people who’d developed one very specific, highly cultivated skill — the real-time translation of arbitrary information into spatially grounded, emotionally vivid, bizarre imagery — through deliberate practice. Their championship performances owed as much to their training as to any general cognitive capacity underneath it. On standard intelligence tests that don’t allow memory palace techniques, most of them would score competently but not extraordinarily. Their championship performances weren’t a display of general cognitive superiority. They were a display of trained, domain-specific skill.
This lines up with expertise research across every domain that’s been checked. What looks like general cognitive superiority in experts often turns out, on closer inspection, to be the expression of domain-specific trained capability rather than a general intelligence edge. The grandmaster’s exceptional chess memory doesn’t generalize to exceptional face recognition or exceptional digit span. The expert radiologist’s diagnostic edge doesn’t reflect generally superior visual processing — it reflects trained pattern recognition inside one specific domain. Viewed through the lens of expertise research, intelligence looks less like a fixed general-purpose capacity and more like a portfolio of developed domain-specific capabilities, each one requiring its own cultivation.
The implication Foer is careful not to overstate — but that the year clearly points toward anyway — is that the ceiling on most people’s cognitive performance in most domains isn’t primarily set by innate capacity. It’s set by whether they’ve put in the deliberate practice required to build the domain-specific capability high performance actually demands. The memory championships are the most compressed, most visible demonstration of the principle, but the principle runs through every domain where performance matters. The question Foer leaves hanging is the one worth sitting with: which areas of your own performance have you quietly accepted a ceiling on that was never actually there?
Solomon Shereshevsky and the Cost of Perfect Memory
The most haunting character in Moonwalking with Einstein isn’t a memory champion. It’s Solomon Shereshevsky, a Russian journalist with hyperthymestic memory — near-perfect recall of nearly everything he experienced — documented by Alexander Luria across the 1920s through the 1950s in the famous case study The Mind of a Mnemonist.
S, as Luria calls him, could hear a long series of words or numbers once and recall it perfectly decades later. He remembered what he’d been wearing, what the room smelled like, what the weather was doing outside, on what felt like any day of his life you could name. His memory was essentially unlimited, essentially permanent, and essentially involuntary.
It destroyed him. S couldn’t hold a job because the flood of involuntary memory kept interfering with present-moment functioning. He couldn’t form abstract concepts, because he couldn’t forget the specific instances that any generalization would have to override. He couldn’t regulate his emotional response to bad memories, because he couldn’t let them fade the way ordinary forgetting gradually dampens the emotional charge of a negative experience. He ended up working as a mnemonist-performer — a circus act, essentially — because his memory made him unemployable at anything requiring ordinary cognitive functioning. He died in obscurity, his extraordinary capacity having built him an extraordinary prison.
Foer uses S’s case to make an important point: forgetting isn’t a failure of memory. It’s a function. Forgetting is what lets us form abstract concepts by filtering out the irrelevant variation between instances. It’s what lets us move past bad experiences as their emotional intensity gradually fades. It’s what lets us function in the present at all, instead of drowning in the specifics of every past moment simultaneously. Memory without forgetting is not an unqualified good. The memory palace techniques competitive memorists use are, in that light, exactly the right answer to the question: they hand over exceptional voluntary recall for the specific things you choose to encode, without disrupting the forgetting that keeps ordinary cognition working for everything else. The goal was never to remember everything. It’s to remember the right things with the right fidelity, and let everything else fade at whatever rate keeps you functioning now.
What Moonwalking with Einstein Gets Right
- The history of memory is genuinely illuminating. The chapters on ancient memory practice, the medieval memory tradition, and the shift the printing press produced are original, well-researched, and genuinely change how you think about what memory is for. Most readers will finish these sections believing something meaningfully different than they believed going in. That’s the mark of genuinely good intellectual writing.
- The first-person account of training is honest about what it actually involves. Foer doesn’t make the journey look easy, and he doesn’t inflate the results past what they were. He writes about the tedium of practice, the plateaus, the uncertainty over whether any of the training was doing anything real. That honest ambivalence about what he achieved and what it means makes the book more credible than triumphalist self-improvement narratives — and more genuinely informative about what deliberate practice actually feels like from the inside.
- The memory palace technique is well-explained and genuinely applicable. The explanation of the method of loci and its neurological basis is clear enough for a motivated reader to actually go apply it. The technique works. For the specific domain it’s optimized for — ordered sequences, arbitrary associations — it produces dramatic improvement in ordinary people with a fairly modest amount of practice time.
- The connection to broader expertise and learning research is sound. The OK Plateau, the role of deliberate practice in expertise, the retrieval practice effect, the relationship between memory and intelligence — all of it is presented accurately and tied together in ways that illuminate the underlying picture. This is the part of the book with the widest practical reach, and it’s handled well.
Where Moonwalking with Einstein Falls Short
- The transfer claims run a little optimistic. The book sometimes implies that developing exceptional competitive memory translates into broader cognitive improvement — a sharper mind generally, better learning, a richer intellectual life. The honest evidence for that is thin. The memory palace dramatically improves competitive memorization tasks. Its transfer to the everyday cognitive functions most people actually care about — understanding complex ideas, retaining what they read, performing better at work — is a lot less direct than the book suggests in its more enthusiastic moments. The underlying principles — retrieval practice, spaced repetition, elaborative encoding — do transfer broadly. The specific competitive technique transfers narrowly.
- The competitive memorization world gets presented as more interesting than it is. Foer is a genuinely engaging writer, but the subculture he’s documenting is small and peculiar, and some of the time he spends on its personalities and its politics serves the narrative more than the reader’s insight. The sections on the world memory championship could run considerably shorter without losing any analytical value.
- The relationship between memory and understanding could go further. Foer’s argument that memory and thought are entangled rather than opposed — his most important philosophical claim in the whole book — is made somewhat tentatively, given how much it implies for modern education and pedagogy. The cognitive science backing it up is substantial and available. A more direct engagement with that research would have made the argument both more credible and more actionable for readers who want to actually apply it.
Key Lessons from Moonwalking with Einstein
- Remarkable memory is a learnable skill, not an innate talent. The competitive memorists Foer studied were ordinary people who learned specific techniques. The techniques are ancient, teachable, and available to anyone willing to put in the practice. The ceiling on your own memory performance, in the domains these techniques apply to, is set mostly by whether you’ve practiced them — not by whatever you were born with.
- The memory palace exploits spatial memory — our most strong system. Attaching information to locations in a mentally navigated space converts fragile semantic memory into durable episodic memory by borrowing the brain’s best long-term storage architecture. That’s why it works. It speaks the memory system’s native language.
- Emotion, bizarreness, and sensory vividness enhance encoding. The brain prioritizes unusual and emotionally resonant information. Deliberately encoding things as bizarre, extreme, or personally resonant images exploits neurological prioritization mechanisms evolution built for survival-relevant information in the first place.
- Test yourself rather than study more. The retrieval practice effect — active recall strengthens memory more than passive review does — is bigger and more consistent than almost any other learning intervention on record. Replace re-reading with self-testing. The effort of retrieval, including the partial forgetting that makes it effortful, is the actual mechanism behind lasting memory.
- The OK Plateau is where practice without deliberate intention ends up. Most skills plateau not for lack of ability but because practice has gone automatic and stopped targeting the ceiling of performance. Breaking automaticity — pulling specific elements of a skill back under conscious attention — is how the plateau gets broken.
- Memory and understanding are entangled, not opposed. The ancient claim that memory training is the foundation of thought is backed by cognitive science. Rich, accessible internalized knowledge is the raw material creative and critical thinking actually run on. Training memory is training thought — not a substitute for it.
- Forgetting is a feature, not a bug. S’s case shows perfect memory isn’t the advantage it sounds like. Forgetting enables abstraction, emotional regulation, and present-moment functioning. The goal was never to remember everything. It’s to remember the right things with the right fidelity, and to develop the active encoding practices that produce retention for what actually matters.
Books Similar to Moonwalking with Einstein
Make It Stick by Peter Brown, Henry Roediger, and Mark McDaniel — The research-based guide to effective learning, covering the retrieval practice and spaced repetition findings Foer’s book gestures toward. Essential companion reading for the cognitive science behind the intuitions memory training surfaces. More practically oriented, less narratively engaging.
The Talent Code by Daniel Coyle — A neurological account of skill building through deep practice and myelin development, which runs parallel to Foer’s account of memory building through targeted training. Both books are making the same underlying argument about the plasticity of apparently fixed abilities and the mechanism deliberate practice actually exploits.
Peak by Anders Ericsson and Robert Pool — The source text for deliberate practice theory, from the researcher whose work underlies both Foer’s OK Plateau section and Coyle’s deep practice framework. More rigorous and less narrative-driven than Foer — essential for the full theory of expertise development.
Why Don’t Students Like School by Daniel Willingham — Willingham’s account of what cognitive science actually says about learning, including the central role background knowledge plays in enabling critical thinking. The scholarly foundation for Foer’s argument about memory and understanding, more direct and better referenced than Foer’s own treatment of the same material.
The Mind of a Mnemonist by Alexander Luria — Luria’s original case study of Solomon Shereshevsky, the man with the perfect and paralyzing memory. Short, strange, and genuinely unsettling in ways that make the necessity of forgetting — and the difference between a well-trained memory and an uncontrolled one — hard to miss.
Who Should Read Moonwalking with Einstein
Read Moonwalking with Einstein if you’re curious what cognitive science actually says about learning, memory, and intelligence — especially if you already suspect, correctly, that the gap between what the research shows and what education actually does is large and consequential. The book is accessible without being dumbed down, narratively engaging without going fluffy, and honest about the limits of its own conclusions in a way that makes it more credible than most popular science writing manages.
Read it if you want the memory palace technique specifically — the explanation is clear enough to start practicing from. Just go in knowing the competitive memorization context is a demonstration of underlying principles that transfer more broadly, and that those underlying principles matter more than the specific technique for most of what you’ll actually want to do with your memory.
Read it if you care about expertise and performance and want a first-person account of what deliberate practice actually feels like from inside it — the plateaus, the frustration, the unexpected breakthroughs, the honest ambivalence about what got achieved. Foer’s account is more honest than most about the gap between process and results, and that honesty is worth more than the triumphalism most self-improvement narratives default to.
Skip it if all you want is practical memorization technique without the intellectual scaffolding around it. Harry Lorayne and Jerry Lucas’s The Memory Book is more technique-dense and less philosophically ambitious — it’ll get you to usable memory palace practice faster if that’s genuinely all you’re after.
Integration: Applying What Foer Found
The memory palace is worth learning for a specific handful of applications: memorizing speeches and presentations (far more effective than note cards), learning names and faces (probably the most practically valuable memory skill for most professionals), encoding numerical data you actually need to retain (account numbers, statistics, data sets), and anywhere ordered-sequence retention matters. For each of these, put in an afternoon building a basic palace out of a familiar location, practice encoding a list of twenty items, and test your recall the next day. The technique is more accessible than it sounds. Initial practice produces surprising results fast.
For daily learning — what gets read, what gets heard in meetings, what gets learned in courses — the retrieval practice principle matters more than the memory palace ever will. After any significant learning event — a chapter, a lecture, a meeting — spend five minutes writing down everything recallable without looking at your notes. Then review the notes, flag what got missed or gotten wrong, and encode those specific gaps. That five-minute active recall habit, applied consistently, will more than double long-term retention of material worth caring about. It costs five minutes. It’s backed by more research than nearly any other learning intervention on the books. Most people skip it anyway, because passive review just feels more comfortable than the effort and partial failure baked into active recall — and that discomfort is precisely the desirable difficulty that makes the whole thing work.
For domain expertise — the kind of deep knowledge that enables genuine creative and critical performance in fields that matter — neither the memory palace nor spaced repetition is the primary tool. The primary tool is extensive, deliberate engagement with a domain’s real patterns and structures, through the reading, practice, analysis, and teaching that actually builds the schema library expert performance runs on. The memory techniques accelerate and support that process. They don’t replace it. Treat them as force multipliers on real learning, not shortcuts around it.
Moonwalking with Einstein Q&A
Can anyone learn the memory palace technique, or does it require exceptional spatial ability?
Research shows it’s broadly teachable across the normal range of spatial ability. Studies have successfully taught the technique to children, elderly adults, people with average spatial recall, and even some individuals with mild cognitive impairment. The barriers are motivational, not aptitudinal. That said, people with strong natural spatial visualization will find it easier at first, and will be able to build more complex and durable palaces sooner. If the technique feels effortful initially, that’s completely normal — it gets easier with practice, and early struggle isn’t a sign of where the ceiling actually sits.
Does competitive memorization transfer to better everyday memory?
Modestly, and selectively. Foer is honest about this — he still lost track of his keys after winning the championship. The memory palace is optimized for ordered sequences and arbitrary associations, the specific challenges competition throws at you. Everyday memory runs on different machinery: prospective memory (remembering to do things), source memory (where you learned something), everyday episodic memory (what happened yesterday). These benefit less directly from competition-specific training. The broader principles — elaborative encoding, retrieval practice, paying attention during initial encoding — transfer a lot more widely than the specific technique does, and applying them to ordinary learning produces more practical benefit for most people than competitive memorization practice ever would.
Is a digital spaced repetition system like Anki a substitute for the memory palace?
Complementary, not a substitute. Spaced repetition software optimizes the timing of retrieval practice to squeeze out maximum retention efficiency — it’s the scheduling tool. The memory palace, and techniques like it, optimizes the quality of initial encoding — it’s the storage architecture. For factual learning at scale — vocabulary, medical terminology, historical names and dates, legal definitions — spaced repetition software is dramatically more efficient than manual review. For ordered sequences and arbitrary associations, memory palace encoding supplies the structural scaffold that spaced repetition then maintains. The best learning protocols for demanding material use both: memory palace encoding at first learning, spaced repetition for maintenance afterward.
How long does it take to build a functional memory palace?
A basic palace built from a familiar location — home, a regular commute — can go up in an afternoon and get used for simple ordered lists in the very first session. You can likely recall a list of twenty items the next morning after just one round of practice. Competitive-level performance — a shuffled deck under two minutes, hundreds of digits held in memory — takes months of dedicated training. For practical everyday use: useful results inside the first week, meaningful proficiency within a month of regular practice, real competency within three months. The entry barrier is genuinely low. The ceiling is very high.
Is there a dark side to exceptional memory?
Solomon Shereshevsky’s case makes the question impossible to dodge. S could remember nearly everything he experienced, and found it paralyzing — he couldn’t abstract away from specific instances to see the pattern, couldn’t regulate the emotional intensity of bad memories, couldn’t function normally at present-moment tasks. Memory and forgetting are both essential: forgetting enables abstraction (filtering out irrelevant variation to spot the pattern underneath), emotional regulation (letting the intensity of a bad experience fade over time), and present-moment functioning (not drowning in the specifics of every past moment at once). Exceptional voluntary recall, the kind the memory palace produces, isn’t the same as involuntary hyperthymesia — you’re choosing what to encode deeply, not remembering everything indiscriminately whether you want to or not. But the underlying principle holds: the goal was never maximum retention. It’s appropriate retention of what actually matters.
What’s the connection between memory training and creativity?
Deeper than most people expect. The classical memory tradition — Cicero, Thomas Aquinas, the Renaissance memory theatre — understood memory training as primarily in service of creative and rhetorical output. You memorized material not to recite it back verbatim but to have it sitting ready as raw material for new combinations and original arguments. The richness of your internalized knowledge directly sets the density of associations your creative process has to draw from. Modern creativity research backs this up: the “prepared mind” that apparently random insights seem to land on is a mind carrying a rich, deeply encoded knowledge base in the relevant domain. The jazz musician who improvises most originally is usually the one who’s internalized the most musical vocabulary. The essayist who makes the most unexpected connections is usually the one who’s read the most widely and actually retained it. Memory and creativity feed each other because creativity is recombination — and you can only recombine what you’ve actually internalized in the first place.
What does Foer say about how education should change?
He argues, carefully, that the pedagogical pendulum has swung too far away from memory training in contemporary education. The reaction against rote memorization — mindless repetition of facts with no understanding or application attached — was a justified response to a genuinely impoverished style of teaching. But it overcorrected into an anti-memory stance that dismisses memory training entirely in favor of “critical thinking” and “learning how to learn” — skills cognitive science shows simply can’t run without extensive internalized domain knowledge underneath them. His recommendation isn’t Victorian rote learning brought back wholesale. It’s teaching memory techniques alongside conceptual understanding, giving students the encoding and retention tools that make learning actually stick, and correcting the false dichotomy between memory and thought that current educational practice is still built on. A practical, research-supported position that neither the traditionalists nor the progressives have fully implemented yet.
What’s the single most useful thing from this book for someone who doesn’t want to compete in memory championships?
The retrieval practice principle. After any learning event worth retaining — a book chapter, a lecture, a meeting, a conversation — spend five minutes writing down everything recallable without checking notes or the source. Then review only what got missed or gotten wrong. This one habit, applied consistently, will more than double long-term retention of material worth caring about. Costs five minutes per learning event. Backed by more consistent research evidence than almost any other learning intervention around. Most people still skip it, because passive review just feels more comfortable. The discomfort of retrieval — the partial forgetting, the effortful reconstruction — isn’t a sign the technique is failing. It’s the mechanism that makes it work. Do the uncomfortable thing anyway.
What Foer discovered over his year of training wasn’t just a set of techniques for memorizing playing cards. He discovered that the cognitive capacity he’d accepted as his fixed endowment — average, unremarkable, the kind of memory that loses keys and forgets what got read last week — wasn’t a ceiling at all. It was a plateau. The real ceiling sat somewhere else, higher than he’d assumed, reachable through training he’d never bothered trying because it had never once occurred to him that trying was an option. And if that was true of memory, the obvious next question was whether it was true of other cognitive capacities he’d quietly written off as fixed too.
That question is the one that sticks around after the specific techniques have already faded from immediate recall — which they will, if nobody keeps practicing them. The book’s lasting contribution isn’t the method of loci, genuinely valuable as the method of loci is. It’s the demonstration, lived from the inside, that the limits most of us accept without ever examining them aren’t actually where we think they are. The ancient teachers knew this. The competitive memorists know it. Foer knows it now. The question he leaves the reader holding is whether they’re willing to go find out where their own ceilings actually sit.
For more on how deliberate practice reshapes cognitive capacity, and what the expertise research says about the relationship between practice, pattern recognition, and high performance, the connection to Foer’s findings adds up to a consistent picture: human capability is more malleable than the default assumption suggests, and that malleability is reachable through specific, evidence-grounded work.
