80/20 Rule in
Speed Reading
The app promises twice the speed and the same understanding. Your eyes are not the bottleneck it describes.
About 20% of a page, the part you need, carries 80% of the use. The other 80% can be skimmed only when you do not need it. That is a rule of thumb for purpose. It is not a trick of the eyes.
The review of the science says you will not double your speed and keep the same grasp. Match the speed to the job. Leave the course that deletes your inner voice.
Normal speed is already a few hundred words
Keith Rayner, Elizabeth Schotter, Michael Masson, Mary Potter, and Rebecca Treiman reviewed what is known about reading, and what speed-reading products claim (Psychological Science in the Public Interest, 2016; the review). Educated adults who read well usually move at about 200 to 400 words a minute. The review's example of a false hope is going from around 250 words a minute to 500 or 750, and understanding the text as well as before. They say that double or triple is unlikely if the goal is real comprehension.
If you do not need a thorough reading, skimming gets you through faster, with moderate comprehension. That is a choice about the job, not a broken eye. The way they name to stay fast and still understand is practice, and a stronger grip on the language, especially vocabulary. Reading, they write, is language. It is not a purely visual sport. Speech came first. The page is a recent trick stacked on top of it.
So the old advice to kill subvocalization, the little voice that sounds the words, aims at the language system and calls it waste. The review's picture is the opposite. Word identification is what sets the pace. A study they cite found word-identification ability, not eye-movement control, was the strongest factor in reading speed. Faster readers do make shorter fixations and fewer looks back. Those eye facts come with skill. They are not a setting you flip.
The look back is doing work
Readers look back. Speed courses often tell you not to. Devices that flash one word at a time in the center of a screen make the look back impossible, because the previous word is gone. The review treats that as a bug if the sentence was ambiguous. People repair a bad parse by rereading. Take the reread away and the repair fails. A garden-path sentence is the plain demo: the first reading is wrong, and the second is how you notice.
Eyes also skip. About 30% of the time a reader jumps past the next word. The word "the" is skipped about half the time or more, because it is short, common, and predictable. A skip is not a failure to read. The word was handled in the edge of vision, or from the sentence. Training yourself never to skip, or to take in a whole line as a picture, fights the way the system already saves time on easy words.
The concentrated skill is knowing which page needs the look back. A contract, a proof, a paragraph you must use tomorrow: slow, and allow the regress. A newsletter you will not quote: skim, and accept moderate grasp. The ignored majority is one speed for every page, sold as a personal record. The reading page is about what you retain. This page is about not paying a course to go faster than comprehension allows. Studying has the same shape. The chapter you will be tested on is not the chapter you skim.
What to do with a page, by the job
| The job | The speed | What you give up |
|---|---|---|
| You must use the argument later | Ordinary pace, about 200 to 400 words a minute if you are already skilled | The fantasy of 1,000 words with the same grasp |
| You only need the gist | Skim | Detail, and the right to claim you understood it |
| A sentence just went wrong | Look back | The rule that regressions are always waste |
| You want to be faster and still precise | More reading, and a larger vocabulary | An app that hides the previous word |
80/20 example: the useful split is purpose, not a percent of eye movements. About a fifth of your pages, the ones you must use, deserve the slow reading. The rest can be skimmed. Rayner and colleagues do not publish that fifth as a lab result. They publish the trade-off. Use the fifth as a sorting rule. Do not use it as a measured law of the retina.
Sort ten pages before you buy a course
For the next ten things you open, write one word before you start: use, or gist. If it is use, read at a normal pace and allow yourself to look back. If it is gist, skim, and do not quote it later as if you had studied it. After ten, count how many "use" pages you still raced. Those are the losses. The gist pages you savored are the other waste.
Illustrative: a student marked eight messages as gist and two papers as use. They had been reading all ten at a guilty medium speed. The two papers got the look back. The eight got a skim and a closed tab. Nothing was purchased.
8020 move: keep the sort. Drop the drill that tells you to silence the inner voice. The review's route to speed with comprehension is language skill, built by reading, not a visual hack.
Try the sort on a real stack before you argue with the review. Take the next thing you were going to "get through." If you will be asked what it said, or you will act on a number inside it, it is a use page. Read it at the pace where you can look back. If you only need to know whether it is worth a use-reading later, it is gist. Skim the headings and the first lines. Close it. Do not feel guilty, and do not quote it. Guilt is how gist pages steal the time the use pages needed.
Vocabulary is the unglamorous half of the review's advice, and it is why a course feels faster than it is. A known word is identified while you are still on it. An unknown word stops the line. The fix is not a wider eye. The fix is having met the word before, in other sentences, which is what ordinary reading does. A week of real pages in the field you work in will move you more than a weekend of flashing words. The flashing drill removes the look back. The review treats that removal as a cost when the sentence was hard.
Keep one number in your head so the ads stay the right size. About 200 to 400 words a minute is already the band for skilled adult reading. A promise of 1,000, or of a novel in an hour, is the advertisement the reviewers put at the front of the paper and then declined. You can be quicker inside that band by knowing the words. You should not expect to leave the band and keep the page.
After the ten-page sort, one more check. Pick a use page you finished. Close it. Write three sentences you could hand to someone who must act. If the sentences are missing, or they are only the title, the pace was a skim wearing a serious face. Read that page again and allow the look back. That second pass is not failure. It is the repair the review says speed tools take away. A gist page does not get this check. You already decided not to use it.
Misreads the course depends on
"Silence the voice and you will triple your speed." The review says a jump from about 250 to 500 or 750 words a minute, with the same understanding, is unlikely. The voice is tied to language. Language is the engine.
"Looking back is the bad habit." Looking back is how a wrong first reading gets fixed. A display that will not let you return makes that fix impossible.
"Skimming is the same as reading, only faster." Skimming is faster with moderate comprehension, when thorough understanding is not the goal. Call it skimming. Do not call it the same grasp.
Champions who claim thousands of words a minute are in the review as the advertisement, not as the result to copy. A Harry Potter book in under an hour is a stunt with a summary afterward. Your standard is whether you can use the page tomorrow without opening it again. If you cannot, you were not fast. You were elsewhere.
