1. There’s something ironic about the fact that the received wisdom about science is that science teaches us not to trust received wisdom. Or, to paraphrase a recent blog post that seems oblivious to this irony: “Scientific expert opines, ‘Science is the belief in the ignorance of experts.’”
I should be fair to Daniel Lemire, the author of that blog post. He does a good job of spelling out the received wisdom about science, as well as of reflecting the orthodox opinion about the scientific expert that Lemire takes as his authority, the Nobel prizewinning physicist, lock-picker, and bongo-player, Richard Feynman.
Unfortunately, Lemire is wrong on both points: the received wisdom about science is hopelessly naive and, far from being a univocal opponent of the importance of expert opinion, Feynman was himself rather confused about the role of iconoclasm in science.
2. Let me begin by tackling the second, in some sense less interesting, point concerning Feynman interpretation.
Far from being of the opinion that all scientists should be iconoclasts who question the experts, the bulk of Feynman’s writing is far more nuanced than the pull-quotes that are turned into the posters that adorn undergraduate science majors’ dorm rooms.
Before appealing to Feynman as an authority on the nature of science, it is worthwhile to keep in mind that Feynman’s field of expertise isn’t the nature of science itself, but theoretical physics. This is important, since, as Feynman himself noted, “In order to talk about the impact of ideas in one field on ideas in another field one is always apt to be an idiot of one kind or another. In these days of specialization, there are few people who have such a deep knowledge of two departments of our understanding that they don’t make fools of themselves in one or the other.” (“The Uncertainty of Science,” John Danz Lecture Series, 1963)
With that in mind, we can appreciate the ways in which slogans like, “science is the belief in the ignorance of experts,” do an injustice to Feynman’s own insights about the nature of science. I’ll briefly sketch five ways in which this is true. Read more »
