The article is so close to a direct Feynman quote that it makes me wonder if the author was subconsciously plagiarizing Feynman. Normally, I wouldn't mind (subconscious plagiarism is everywhere). But in an article about intellectual honesty I would expect the author to "bend over backwards" to identify and declare potential sources of plagiarism. ;-)

Especially as while Feynman said that I highly doubt he was the first to think it. He was, very likely, merely distilling things he'd heard before much as the current author was.

"Cargo Cult Science", adapted from a commencement address given at Caltech (1974)

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; other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked — to make sure the other fellow can tell they have been eliminated.

Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can — if you know anything at all wrong, or possibly wrong — to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it...

In summary, the idea is to try to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another.
