Speed Reading: What Is Achievable and What Is Not

Speed reading claims run into a physiological constraint that no technique removes.

The constraint

Reading involves saccades - rapid eye jumps - and fixations, during which information is actually acquired. The perceptual span for useful information is limited to a small number of characters around the fixation point, and this is a property of the visual system rather than of training. Techniques promising to expand it dramatically, or to read whole lines or pages at a glance, are working against that constraint rather than around it.

What the research finds

Studies of speed reading have generally found that large gains in words per minute come with corresponding losses in comprehension, particularly for unfamiliar or complex material. What trained speed readers often do is skim more effectively - using headings, topic sentences and structure to sample the text intelligently. That is a genuine and useful skill, and it is not the same as reading everything faster with full comprehension.

What actually helps

Reducing subvocalisation helps modestly for easy material and not for difficult material, where the inner voice supports comprehension. Prior knowledge is the largest determinant of reading speed for a given text, so building background knowledge speeds future reading in a domain far more than any technique. Deciding what not to read carefully is the highest-value skill: skim to determine relevance, then slow down for what matters.

Where a supplement fits here

If you have worked through the behavioural and medical options above and want to add a supplement, Cognizil is a stimulant-free liquid formula available from the Cognizil official website. We would rather you addressed sleep, activity and any underlying medical cause first — those have stronger evidence than anything in a bottle, including ours.
