Is there a limit on the rate at which incoming information can be comprehended?
I have tried speed reading myself in the past. From the research papers I have read back then, it seemed like there is no basis or evidence to the claim that with practice, reading speed can increase to more than 600-700 words per minute without any loss of comprehension (Some of the most bizarre claims include 25,000 words per minute. I would have been more impressed if the person claiming it wasn't selling online courses about speed reading for large sums of money).

I can't find the studies I found back then, but a meta-analysis by Keith Rayner†, Elizabeth R. Schotter, Michael E. J. Masson, Mary C. Potter, Rebecca Treiman (2016) seems to show that reading pace is highly determined by language skills and an extensive vocabulary. They show that generally there is a trade off between pace and comprehension, and some of the claims for a very high reading pace were based on prior knowledge of the texts. However, mild improvements can be achieved with practice. This article looks extremely fascinating and I wish I had the time to read all of it.

Edit: Only now do I realize how ironic my last remark was.
