The Spritz Method: What Science Actually Says About Speed Reading (And What It Doesn't)

Speed reading promises miracles: 1000 words per minute, full comprehension, a few weeks of training. It sounds great. It's also, for the most part, false. Here's what decades of psycholinguistic research actually show — and when the Spritz method genuinely has value.

The promise that's too good to be true

Search "speed reading" on Google and you'll find dozens of sites promising to triple your reading speed while keeping comprehension intact. Apps like Spritz, Spreeder, and ReadQuick advertise speeds of 700, 1000, sometimes 1500 words per minute.

The reality? When serious researchers actually tested these claims, they found something different. The landmark paper is from 2016: Keith Rayner and his team published a comprehensive review in Psychological Science in the Public Interest^[1]. Their conclusion leaves no room for ambiguity:

"There is no magic bullet that allows people to read faster without a concomitant loss in comprehension." — Rayner, Schotter, Masson, Potter & Treiman (2016)

Not a great sales pitch. But honest. Before we understand why, we need to know how reading actually works.

How reading actually works

Contrary to what most people think, your eyes don't glide smoothly across the line. They jump — these are called saccades — with pauses in between called fixations. During saccades (about 20 to 40 milliseconds each), your brain is effectively blind. It's during fixations (about 200 to 250 ms) that information is processed.

At each fixation, your eye perceives a narrow area: about 3 to 4 letters to the left of the fixation point and 7 to 8 letters to the right. Anything further is blurry^[2].

Another important detail: about 10 to 15% of eye movements are regressions — going back to re-read a word or phrase. This isn't inefficiency. It's a natural, essential mechanism for comprehension.

On speed itself: Marc Brysbaert's 2019 meta-analysis^[3], which aggregates dozens of studies, gives solid reference numbers:

• Silent non-fiction reading: ~238 words/minute
• Silent fiction reading: ~260 words/minute
• Reading aloud: ~180 words/minute

These are the real numbers for an educated adult. Not 100, not 1000. Between 200 and 300.

What is the Spritz method?

Spritz is a reading app that uses a well-known research technique: RSVP, or Rapid Serial Visual Presentation. The principle is elegant: instead of moving your eyes across a text, the text flashes past, one word at a time, at a fixed position on the screen.

The idea: eliminate saccades (your eye no longer moves), suppress regressions (there's nothing to go back to), and align each word on its Optimal Recognition Point (ORP) — the exact letter where your eye naturally fixates during normal reading.

On paper, it saves time. In practice, it gets complicated.

The problem Spritz didn't solve

In 2014, Elizabeth Schotter, Randy Tran, and Keith Rayner published in Psychological Science a study with a blunt title: "Don't Believe What You Read (Only Once)"^[4]. The researchers compared two reading conditions:

• Normal reading, where participants could go back.
• "Blocked" reading, where already-read text was hidden — like in RSVP.

The result: comprehension drops significantly in the condition without backward movement. And not just a little: for questions about ambiguous or syntactically complex sentences, the differences are substantial.

Eye regressions aren't a bug. They're a feature. Your brain uses them to disambiguate complex sentences, lock information into memory, catch a word it misread. RSVP, by eliminating them on principle, amputates an essential cognitive tool.

And the famous "focal point" — the ORP?

The existence of a preferred fixation zone within a word has been documented since the 1970s — researchers call it the preferred viewing location, slightly to the left of center. On this point, Spritz is correct: aligning words on this optimal fixation point does reduce visual effort.

But let's not overstate the impact. It makes reading a bit more efficient at a given speed. It doesn't magically turn your brain into a 1000 words/minute machine. The bottleneck isn't in your eyes, it's in the linguistic processing that follows.

So what is RSVP actually useful for?

It would be dishonest to say the method is useless. It isn't — just not for what's being marketed. Here are the real use cases where RSVP brings genuine value:

1. Skimming — filtering what's worth reading

Before investing 30 minutes in a long article, 90 seconds of RSVP at 500 words/minute gives you the topic, tone, and structure. Not the nuance, not the subtleties. Just enough to decide: dive in or skip.

2. Simple, familiar content

Emails, news, light blog posts, summaries. On text where you don't need to go back, RSVP delivers on its promise. You do read faster, with comprehension sufficient for the purpose.

3. Training against excessive subvocalization

Many readers "vocalize" each word mentally, which caps their speed around 200–250 words/minute (the maximum speed of inner speech). RSVP, by imposing a higher rhythm, forces the brain into direct recognition mode. Used as exercise, it's a good tool for breaking that habit.

4. When your hands aren't free

Crowded subway, waiting in line, transit. RSVP reads with a single point of attention, no scrolling, no page-turning. Practical.

5. Some dyslexic profiles

Several studies suggest RSVP can help some dyslexic readers by reducing visual load and problematic eye jumps. The topic is still debated, but results are promising for this specific population.

How to use RSVP smartly

Drop the "read faster all the time" goal. See RSVP as one more tool in your box, with its specific use cases. A few principles:

• Start at 300 words/minute. Slightly above your natural speed — comfortable to begin.
• Match speed to content. 500 WPM to skim a newsletter. 300 for a deep article. Not more for technical text.
• Don't confuse speed with learning. To retain information, you'll need to return to it — which RSVP prevents by design. Use it for the first pass, not for study.
• Take breaks. RSVP demands sustained, uninterrupted attention. Beyond 10–15 minutes, cognitive fatigue makes comprehension drop faster than speed gains it.

What to remember

Speed reading, as it's sold, is a myth. Realistic speed gains exist, but they come at the cost of reduced comprehension — except when the content allows for it. RSVP isn't a magic pill: it's a targeted tool, useful for skimming, simple content, and training, much less so for study or complex texts.

The good news: once you know this, you can use it intelligently. And there's nothing scammy about that.
