More on the crisis in research: Feynman on 'cargo cult science'

By Michael Hiltzik

After reading my weekend column about the crisis in life science research, Hajime Hoji of USC's linguistics department reminded me of the late Richard Feynman's brilliant deconstruction of the flaws and pitfalls of science as it's done in the modern age.

"Cargo Cult Science" was adapted from Feynman's 1974 commencement speech at Caltech, where his spirit reigns as one of that institution's two certified saints. (The other is Robert A. Millikan, Caltech's first president.) The text appears in his 1985 book, "Surely You're Joking, Mr. Feynman!" Here are some excerpts, but the talk is worth reading in its entirety, both for Feynman's lucid, engaging style and the depth of his thinking.

In the talk, Feynman discussed how much laypersons and scientists themselves take for granted about research results. "We really ought to look into theories that don't work, and science that isn't science," he said. "Cargo cult science" was his term for research that never seemed to yield provable results, but acquired public acceptance because they possessed the veneer of rigorous methodology.

What cargo cult science lacked was something that, he observed, was never actually taught to Caltech students. "It's a kind of scientific integrity...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....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."
