The Difference between 'True Science' and 'Cargo-Cult Science'
“Science is the belief in the ignorance of experts” is how the great Nobel Prize-winning physicist Richard Feynman defined science in his article “What is Science?” Feynman emphasized this definition by repeating it in a stand-alone sentence in extra large typeface in his article. (Feynman’s essay is available online, but behind a subscription wall: The Physics Teacher (1969) volume 7, starting page 313.)
Immediately after his definition of science, Feynman wrote: “When someone says, ‘Science teaches such and such,’ he is using the word incorrectly. Science doesn’t teach anything; experience teaches it. If they say to you, ‘Science has shown such and such,’ you should ask, ‘How does science show it? How did the scientists find out? How? What? Where?’ It should not be ‘science has shown.’ And you have as much right as anyone else, upon hearing about the experiments (but be patient and listen to all the evidence) to judge whether a sensible conclusion has been arrived at.”
And I say, Amen. Notice that “you” is the average person. You have the right to hear the evidence, and you have the right to judge whether the evidence supports the conclusion. We now use the phrase “scientific consensus,” or “peer review," rather than “science has shown.” By whatever name, the idea is balderdash. Feynman was absolutely correct.
When the attorney general of Virginia sued to force Michael Mann of "hockey stick" fame to provide the raw data he used, and the complete computer program used to analyze the data, so that “you” could decide, the Faculty Senate of the University of Virginia (where Mann was a professor at the time he defended the hockey stick) declared this request -- Feynman’s request -- to be an outrage. You peons, the Faculty Senate decreed, must simply accept the conclusions of any “scientific endeavor that has satisfied peer review standards.” Feynman’s -- and the attorney general’s and my own and other scientists’ -- request for the raw data, so we can “judge whether a sensible conclusion has been arrived at,” would, according to the Faculty Senate, “send a chilling message to scientists … and indeed scholars in any discipline.”
According the Faculty Senate of the University of Virginia, “science,” and indeed “scholarship” in general, is no longer an attempt to establish truth by replicable experiment, or by looking at evidence that can be checked by anyone. “Truth” is now to be established by the decree of powerful authority, by “peer review.” Wasn’t the whole point of the Enlightenment to avoid exactly this?
