(people need to upvote parent). You started from the lowest-level (reading word by word) but I started at the highest: after skimming the first couple of sentences I scrolled down trying to get an "overview", I tried to take in the main things, to read a Conclusions section, to read something that would put all these things in perspective. (The "background" first section and the couple of sentences that precede it aren't any kind of good abstract, or if they are then I missed it while skimming.) But I didn't see it - I couldn't "see the forest for the trees." So take it as strike two against the author and therefore against nootropics: while there might be a wealth of detail that it uncovers, too many details will make you lose the perspective, and, indeed, the whole point. Like when someone writes a groundbreaking optimizing compiler or something, but can't even tell you why.
