Short Summary
Main recommendation: Do not rely on popular speed reading tricks such as peripheral-vision page scanning or silencing your inner voice; instead, build language processing skills and use skimming with a systematic structure when you need to extract information quickly. The video argues that reading speed is limited by cognitive processing rather than eye movement, and that faster reading generally involves a trade-off with comprehension.
Key Points
- Peripheral-vision reading is biologically limited: words become unreadable about 3 degrees from the point of fixation, so the foveal area (roughly the width of a thumb at arm's length) is what allows reading.
- The inner voice (subvocalization) aids comprehension and word recognition, so silencing it tends to reduce understanding.
- Regressions (going back to reread) are common even among skilled readers, and research links them to better comprehension; RSVP apps that eliminate them trade away understanding.
- Saccades last about 20 milliseconds, and fixations about 250 milliseconds; the bottleneck is cognitive processing, not eye movement.
- Skimming can increase reading speed two to three times but reduces comprehension.
Details Worth Noting
- Concrete instructions:
- To build reading speed, practice with language and expand vocabulary, since familiar words get shorter fixations and some are skipped entirely.
- When skimming a book, first read the table of contents to understand its structure, then read the headings, and the first and last paragraph of each chapter.
- If focusing on a particular section, read the first and last sentence of each paragraph.
- Approach skimming systematically rather than zigzagging the eyes across the page, which the research describes as a poor strategy.
- Do not try to suppress the inner voice or avoid rereading when you need comprehension.
- The speaker tested himself speed reading a biography of Elon Musk and jokingly said afterward only that 'it's about Elon Musk,' not reporting real comprehension.
- Anne Jones read all 784 pages of Harry Potter and the Deathly Hallows in about 4.7 minutes (over 4,200 words per minute), but the research cited does not explain how such readers achieve this.
- A 2014 University of California San Diego study used a trailing mask that hid words after the eye moved past them; the paper found regressions crucial to comprehension.
- The cited paper on skimming suggests effective speed readers are often knowledgeable about the topic and accept lower comprehension when skimming.
Bottom Line
Faster reading mostly comes from stronger language and vocabulary skills, while speed techniques that cut out rereading or the inner voice tend to cost understanding.
