There is one feature I notice that is generally missing in 'cargo cult science'... It's a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty —a kind of leaning over backwards... For example, if you're doing an experiment, you should report everything that you think might make it invalid —not only what you think is right about it... Details that could throw doubt on your interpretation must be given, if you know them.
