How scientific is it? What I mean is I just read Surely You're Joking, Mr. Feynman! and in the very last section on "cargo cult science" he says: He goes on later to talk about a psychology experiment with rats which he says "discovered all the things you have to do to discover something about rats" that was largely ignored by other researchers. So has it changed in the last 50 years or so? Has it become more scientific, have the experiments become more repeatable (or rather, do they repeat them more now)? Or is it still pretty cargo-cultish at times?
