Well if this was possible, Photoreading, than that would be amazing. I tried it and never got it really to work.
Derren brown could have used trickery, (but he also did this with this average joe, he taught it to him and made him almost win a pubquiz), so i read a bit of the book of paul, and it’s interesting. but it’s not just flicking through the book. you also have to analyze it quite deeply by checking out chapter titles, other headings, words that appear a lot. so there is more preparation to it than you would hope.
Still kim peek, a real genius (R.I.P), i saw him do something similar when memorizing material. he can read like 2 pages atime in also like 8 seconds? something. I believed that, cause the guy simply knew almost everything he read.
So as a psychologist student, i can’t say it is absolutely impossible. but it’s highly unlikely.
even photographic memories we have never really experienced in real life, yeah really great amazing ridiculous memories for citys or maps or numbers or autobiographical stuff. But not for everything i think? unless someone proves me wrong.
BTW. i gave up photoreading & speedreading as well, i don’t think that will help you read a philosophy book for example. or any study material.
