You’d have to be a fucking moron not to recognize the colloquial use of 90%. I’ve been in the trenches. I’ve published (in Science, is that good enough?) and seen forced retractions due to fraud. A LOT of the literature is shit. I’m not saying science is shit. I’m a scientist, I assert there is no way to understand the world other than through science. I’m saying the majority of the literature is shit.
