I am just wondering does the author alao distrust science when it comes to medical treatments and the law of gravity, or does is his distrust highly selective.
pretty selective. Maths has proofs. Logical reasoning from first arguments that a thing is true or not. It either is, or is not, proven. End of. Physics as applied maths, pretty solid. We need to conduct experiments to verify that nature agrees with our mathematical constructs, but on the whole these are simple and unequivocal. e.g . gravity. Particle physics gets dodgy because of the vast range of collision results…
The subject in question is not some fuzzy social science: this is a straightforward assessment of reading ability for a given color scheme. You access objective metrics like ability to detect errors, reading speed, accuracy, etc.
Arguing with this is like disputing the fact that high heels make for terrible running shoes. Research in question with be quite similar.
