Richard Feynman
Nobel physics, safecracking on the side
Science

Feynman worked on the bomb at twenty-four, won the Nobel for quantum electrodynamics, and later found the O-ring flaw that destroyed Challenger by dropping a piece of rubber into ice water on television. He is the great enemy of sounding clever: if you cannot explain it simply, he thought, you do not understand it, and pretending otherwise is the one unforgivable move.
We've learned from experience that the truth will out.

Details that could throw doubt on your interpretation must be given, if you know them.

The first principle is that you must not fool yourself—and you are the easiest person to fool.
"Cargo Cult Science", Caltech 1974 commencement address
You must do the best you can—if you know anything at all wrong, or possibly wrong—to explain it.

So it's the implication which has been conveyed, not the fact, which is true, and the difference is what we have to deal with.

Never say that you'll give a talk unless you know clearly what you're going to talk about and more or less what you're going to say.

And it's this type of integrity, this kind of care not to fool yourself, that is missing to a large extent in much of the research in Cargo Cult Science.

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.
