I Was Wrong About Speed Reading: Here are the Facts

Seven years ago, I read some books and articles on speed reading and started practicing some of the methods. I found I was able to increase my reading speed from 450 word per minute to 900 in the drills, so I published an article entitled, Double Your Reading Rate, which has since become one of the most popular on this website.

When I wrote the piece, I based the article purely on my personal experience along with the how-to books I had read. I didn’t have any solid scientific research to back my experiments.

Since that time, I’ve had some lingering doubts about speed reading. In addition to seeing some flickers of research that made me suspicious about speed reading programs, I had mostly stopped using the techniques I originally advocated. My reading diet had switched from lighter self-help, to denser and more academic writing. That meant comprehension, not speed, was the bottleneck I was trying to improve.

Now, nearly a decade later, I decided to do some in-depth research into speed reading to bring you the facts.

Is It Possible to Read 20,000+ Words Per Minute?

Some speed reading claims can be tossed aside immediately. Claims that you can read a book as fast as you can flip through a phone book are completely impossible on anatomical and neurological levels.

First we have anatomical reasons to throw out absurdly high reading rates. In order to read, the eye has to stop at a part of the text, this is called fixation. Next, it must make a quick movement to the next fixation point, this is called a saccade. Finally, after you jump a few points, the brain has to assemble all this information so you can comprehend what you’ve just seen.

Eye-movement expert Keith Raynor, argues that even going beyond 500 words per minute is improbable because the mechanical process of moving your eye, fixing it and processing the visual information can’t go much faster than that.

Speed reading experts claim that they can work around this problem by taking in more visual information in each saccade. Instead of reading a couple words in one fixation, you can process multiple lines at a time.

This is unlikely for two reasons. One, the area of the eye which can correctly resolve details, called the fovea, is quite small—only about an inch in diameter at reading distance. Processing more information per fixation is limited by the fact that our eyes are rather poor lenses. They need to move around in order to get more details. This means that eyes are physically constrained in the amount of information they achieve per fixation.

Second, working memory constraints are at least as important as anatomical ones. The brain can hold around 3-5 “chunks” of information at a time. Parsing multiple lines simultaneously, means that each of these threads of information must remain open until the line is fully read. This just isn’t possible with our limited mental RAM.

What about systems like Spritz? Spritz works by trying to avoid the problem of saccades. If each word appears in the same place on the screen, your eye can stay fixed on that point while words flip through more quickly than you could hunt them down on a page. Indeed, using the application gives a strong impression that you can read very quickly.

Their website claims to have research showing faster reading speeds, but unfortunately I was not able to find any independent, peer-reviewed work substantiating these claims.

Working memory constraints here too, enforce a limit on the upper speed you could use Spritz and still be considered to be “reading” everything. Remember reading was a three step process: fixate, saccade and process. Well that processing step slows down regular reading too. If there are no pauses in the stream of words, there isn’t enough time to process them and they fall out of working memory before they’re comprehended.

Is It Possible to Make Moderate Speed Gains Through Training?

The evidence is clear: anything above 500-600 words per minute is improbable without losing comprehension. Even my own perceived gain of 900 word per minute meant that I was probably losing considerable comprehension. This was masked because the books I was reading had enough redundancy to make following along possible with impaired comprehension.

However, according to Raynor, the average college-educated reader only reads at 200-400 words per minute. If 500-600 words forms an upper bound, that does suggest that doubling your reading rate is possible, albeit as a hard upper limit. Can we still get moderate speed reading gains?

There seems to be some mild evidence here in favor of speed reading. One study of a course had some students quadruple their speed. Another study showed some speed reading experts reading around the 600 word per minute level, roughly twice as fast as a normal reader.

However there’s a trap here. Speed reading may possibly make you a faster reader, but it’s not clear the speed reading techniques are the cause. Second, speed reading trainees tended to read faster, with less comprehension, than non-speed readers. Since measuring comprehension is more difficult than speed, I believe many new speed readers can fall into the trap I did: believing they’re making an unqualified doubling of their reading rate, when in reality, they are doing so at a significant tradeoff of comprehension.

Do Speed Reading Techniques Work?

If the evidence suggests that reading faster may be possible, albeit more modestly, it casts a much harsher light on certain speed reading dogma. The most dangerous is the idea that subvocalization should be avoided to read faster.

Subvocalization is the little inner voice you have when reading that speaks the words aloud. When you started reading you probably spoke out loud with that voice, but you learned to silence it as you got older. If you turn your attention to it, however, you can still hear yourself making the sounds of the words in your head.

Speed reading experts claim that subvocalization is the bottleneck that slows down your reading. If you can learn to just recognize words visually without saying them in your inner voice, you can read much faster.

Here the evidence is clear: subvocalization is necessary to read well. Even expert speed readers do it, they just do it a bit faster than untrained people do. We can check this because that inner voice sends faint communication signals to the vocal cords, as a residue of your internal monolog, and those signals can be measured objectively.

It’s simply not possible to comprehend what you’re reading and avoid using that inner voice. So reading faster means being able to use this inner voice faster, not eliminating it. To further that, expert speed readers who were studied also subvocalized, they just did it faster.

The other main recommendation I made in my speed reading article was using a pointer. This means moving your finger or a pen to underline the text as you read it. This technique is supposed to help you make eye fixations and reduce the random wandering of the eye which can waste time. One study suggests that this apparent function isn’t realized, and that the pointer functions as a pacing device, while actual eye fixations are uncorrelated with pointer or hand movements.

If You Shouldn’t Speed Read, How Should You Read Better and Faster?

In my research for this article, I did find a couple factors that were associated with better reading speed, without sacrificing comprehension. None of these are magic fixes for your reading woes, but a mild treatment that works is better than a fantastic one which doesn’t.

Reading Tip #1: Skim Before You Read

Many speed reading courses are actually teaching skimming techniques, even if they package it as “reading” faster. Skimming is covering the text too fast to read everything fully. Instead, you’re selectively picking up parts of the information.

Skimming, isn’t actually a bad method, provided it’s used wisely. One study found that skimming a text before going on to reading it, improved comprehension in the majority of cases.

Reading Tip #2: Improve Your Fluency to Improve Your Speed

Fluent recognition of words was one of the major slowing points for readers. Subvocalization, that mythical nemesis of speed readers, is slower on unfamiliar words. If you want to speed up reading, learning to recognize words faster seems to improve your reading speed.

Fluency isn’t just an issue for reading in your non-native language. It also matters for technical documents or prose which uses unfamiliar vocabulary. If I’m reading a text that uses jargon like mRNA, or obscure words like synecdoche, I’m going to pause longer. That will slow my reading speed down.

The best way to improve fluency is to read more. If you read more of a certain type of text, you’ll learn those words faster and read better. If you’re a non-native or fluency significantly impacts your reading speed, then even a tool like Anki may be useful for learning hard words.

Reading Tip #3: Know What You Want, Before You Read It

Part of the reason skimming first might appear to help is that it allows you to map out a document. Knowing how an article or book is structured, then, allows you to pay more attention to the things you think are important.

Another tip offered in a lot of speed reading courses, which is likely good advice, is to know what you’re trying to get out of a text before you read it. Thinking about this before you start reading allows you to prime yourself to pay attention when you see words and sentences that are related. Even if you’re reading at a speed which has some comprehension loss, you’ll be more likely to slow down at the right moments.

This isn’t always possible. I read a lot of books unsure about what I want to discover in them. Fiction and reading for pleasure can’t be reduced to a mission objective. However a lot of bland, necessary reading in our lives fits this type. Speeding it up might be worthwhile if it leaves us more time for reading with curiosity.

Reading Tip #4: Deeper Processing Tasks to Improve Retention

Sometimes you don’t want speed at all—you want near full comprehension. When I was in school, I needed to read most textbooks in a way that I could retain nearly every fact and idea I encountered later. It’s not just full comprehension you want, but long-term memory of the information.

Here cognitive science offers some suggestions. A principle of memory is that we remember what we think about. So if you want to remember the ideas of a book, highlighting bolded passages isn’t the best idea. Highlighting causes you to think about bolded words, not what they means.

Some alternatives are taking paraphrased, sparse notes or rewriting factual information you want to remember as questions to self-quiz later.


I was wrong. Subvocalization shouldn’t be avoided. Doubling your reading rate may be possible from a lower range (250 to 500 words per minute, for example), but it’s probably impossible to go beyond 500-600 words and still get full retention. Speed reading may have some redemption as an alternative to skimming text, but even here the benefits come from how speed readers conceptually organize the text, and not on the mechanics of eye movements.

In terms of accuracy, my original article hasn’t aged too well. In my more recent courses, I still teach speed-reading, but I had already shifted mostly to the speed-reading-as-intelligent-skimming paradigm which is a bit more defensible. Still, I’ll be sure to include this research in any new courses I develop.

I apologize to any readers who may have gotten outsized hopes about what speed reading could accomplish. My goal, as always, isn’t to present a fixed dogma of what it takes to learn better, but to research and experiment with new ideas. Unfortunately, sometimes that’s a path that dead-ends or winds back on itself. In any case, I’ll always do my best to share whatever I find with you.

    Super glad I came across this post. A year ago, I had taken a hyped up class on speed reading and had this nagging feeling that getting rid of subvocalization was hurting me. Glad to have stumbled upon this post and to hear that an experienced speed-reader such as yourself also has issues with the “no subvocalization” dogma. If only I knew a bit earlier!

    As a side note, I’ve been really enjoying your blog. Keep it up!

    What are these techniques?

    *Sigh* It seems wherever you find an honest, skeptical, science-based critique of speed reading, you find these types of comments. Usually written by some robot that was programmed in Russian and then translated into English. And the claims! Oy Vey!
    “1,000 words per minute! Every time! 100% comprehension!”

    100%? Really? That’s like a professional basketball player saying they NEVER miss a shot and score a 100 points per game on average before the second quarter is over. Look, if you can read Pride and Prejudice in 30 minutes and break the Louvre-sprinting record by a minute and a half, fine. Just let’s not discuss art together. I’d say a proficient reader reads at between 250-400 words per minute at a clip when they LOVE what they’re reading. And then they slow down considerably to enjoy the words and paragraphs they particularly find rewarding.

    Do you know how long I take to read a simple sonnet? Somewhere between half an hour and a decade. Funny thing about poetry is, the longer it takes me, the less I realize I’ve comprehended. A poem I assumed I understood fully after a week becomes one I’d only half understood in a year. Many good, and some bad, pieces of fiction affect me the same way.

    I love Derren Brown, and he does incorporate many skills and techniques out there on the “self-improvement” circuit. But he’s not above a bit of mischief and trickery, and he admits it. Because he’s an entertainer. Pick up a copy of his “Tricks of the Mind” and you’ll realize that while he does have a fairly advanced understanding of these sorts of things, he is also highly skeptical of their claims – especially in the world of NLP and hypnotism. And he’s a goshdarn stage hypnotist!

    My suggestion to most people when it comes reading is to read your way through Mortimer Adler’s “How To Read A Book” a few times until you’ve mastered everything it has to teach. You’ll forget all about speed reading then. Some of the greatest readers in history were blind or nearly blind. They didn’t worry about how “fast” they did it any more than a potter worries about how fast they can make a piece of ceramic art. They read widely and deeply and then dipped back in for more. You’ll find that as you get older you return some tomes over and over. A great lover isn’t the man who can “finish the job” with a hundred women in an afternoon. Better the man who can satisfy the same woman every night.

    Love your avatar. Perfect in response to Bill bob’s comment. But flight? Really? Think bigger! I aim to be the first man to orbit the earth AND breathe in space wearing only my swimming trunks! It’s a very rare feat you know. But maybe not so rare after I break the barrier. I aim to be the Roger Bannister of the space race – a very literal, physical race to the top.

    2 decades ago I used spoken aloud reading devices too, today TTS narrators max about 650wpm being clarity of speech that defines easier listening speeds and some can make omission tricks in skipping vowels, stop-words to main-words, where this concept has been around for quite some time it’s know as ‘Speed-Listening’ and yes it’s a good alternative without needing to train reading speed which I still use if I’m too tired reading alone. I’ve chosen ‘Speed-Reading’ as I’ve taken manageable steps to actually build upon monitoring out my visual field and speed. My conclusion is speed-reading isn’t for most as a lot of people just don’t like doing/train as a game of mental agility, like memory feats I discovered memorizing like up to 100 unknown vocabulary words learning all like 20 minutes per lot, but demonstrating proved no interest to anyone concludes that in this day/age nobody must care for intensive use of mind/intellect and as many enjoyed Scott’s article to suit, which can only make me wonder about the guy spiffy expressionism measures to such anatomical/neurological order of things.

    Scott, I am grateful , It is clear that you doing great service to society by collaborating your experience and sharing it in a meaningful way that provides clear and more broader perspective on specific subject of speed reading.

  • Scott Young

    I would say I was wrong about subvocalization, which was one of the main advocated strategies of speed reading. Although the evidence for reading with a pointer is more mixed, I don’t do it anymore, so that’s a reversal of practice, even if not a condemnation from the literature.

  • Mike Hall

    I took a speed reading course many years ago and they basically taught us how to skim. I read pretty fast if I am just reading for pleasure, plus I skim over some of the parts that I don’t think adds much to the story. That is probably one reason I like to go back and reread some books a few months later and still enjoy them. I read very slow if I need to remember something. I think one of my biggest problems is that I keep going back and rereading parts that I have already read. Any thoughts or recommendations on how to improve that.

  • Mosbie Chiweza

    I’m glad you checked and researched and had the guts to say you were wrong. Somehow it strangely validates your work. I sometimes get tired of blogs where the writer is clearly wrong and won’t make an effort to take some research.

  • Kaci

    Thanks for being honest and direct.

  • Thanks for the honesty here. I had never had much success with speed reading – but skimming definitely works.

  • Te Wairama Renata

    Yes & he is very good apparently.

  • Ellen

    Please let me know what speed reading course you took and an online link and text that you used.

  • Jordan R G Boyer

    Yes, I don’t want to speed read. I want to get to this 500-600 wpm level of reading though! My current speed is just under 200 wpm. How do I find out more about this? I can’t search speed-reading or I get techniques on how to “read 1000 wpm” which is not my goal. Any suggestions? Anyone?

  • Guillermo Sarco

    For me always was a challenge to read faster, but I can remember some details of a paper or from a book better than my colleagues. So I prefer read slower.

  • CodeToad

    Hey Jordan,
    There’s at least one issue that Scott failed to cover. From my experience and research there’s substantial evidence indicating that the smarter you are…the slower you tend to read! You read that right. It seems that people who are smart try to extract the “most information” from what it is that they’re reading and this “mental straightjacket” only serves to slow them down.
    So, the first thing I’d recommend is that you deliberately try to read faster, just don’t go so fast that you lose “continuity” (it may feel uncomfortable at first, and that’s ok — it’s a little like lifting weights for the first time: uncomfortable, but doable). Scott’s also right-on that you can train your eyes to recognize words faster and you can intentionally push for speed AND comprehension. I disagree with him on the finger-pointer method to some extent. I felt like using a bookstand (35º IIRC) and using my finger to mark the line “I’m on” and advancing it when I finish each line seemed to help me improve my reading speed. Of course — I also use a kindle, so the bookstand method doesn’t help there 🙂
    I also agree with the “agile” idea of “starting with the end in mind”. I have plowed through many pages of documentation via skimming — only stopping where I thought it was valuable based on my objectives. This has helped me greatly in my professional career.
    Good luck!

  • Thank you for your honesty. It takes a great deal of courage, having talked and taught a particular skill or knowledge, to come back to admit you were wrong about it. So thank you. You have just saved me many hours practising ineffectual techniques.

    What you mentioned for alternatively for speed reading I sort of do it already.
    “I speed read”, as in there is many words I skip and I only read what catches my eyes. I do this for several reasons, one is if I scrupulously read things I cannot keep track easily and I try to take every thing with me. I do the same things with everything. When I go shopping I scan things instead like some other people that I have observed take almost every piece of clothing out to get a look. When I only look at it all and pick whatever attracts my eye first. Since, I do this with everything it means I cannot like some people scrupulously look at things. I do look at things meticulously, but only what has attract my eyes. I am thankful for this ability, because it saves me time, but at the same time I doubt it. Because the fear that I might something that my teachers will decide to randomly test me on. With my way of speed reading I am actually to understand much easily of what I read instead of scrupulously reading it. I believe it is because reading every single word on the page does not help your mind retain something, because reading is a procedural ability that does not require cognitive energy once learned. So when I read I am unable to have any of the words go into the thinking part of my brain. So using my method I am actually able to use my cognitive abilities and retain things. Even catch things that people don’t catch.
    I don’t know how I am able to figure things out, I know how to get other people to attain this ability and I have a thinking mind. Haha, and I’m so smart at being lazy (efficient).
    I am not being arrogant. The real definition of arrogance is not being aware of the reality and thinking you are higher, or ignoring you have faults. I just know what kind of person I am. I have use my intelligence to attack others, but only give out information (Which I really don’t do any more, because people are always stealing from me) Lol my Bio teacher wasn’t able to explain something and didn’t even understand something that I asked her, and then I figured it out myself and she ended using my words to teach the class. So I keep my mouth shut, even though I want to tell someone.
    “Wisdom, talent is useless when not recognized”
    I’m done talking.
