Indeed, it’s a virtue for a scientist to change their mind. The biologist Richard Dawkins recounts his experience of ‘a respected elder statesman of the Zoology Department at Oxford’ who for years had:
passionately believed, and taught, that the Golgi Apparatus (a microscopic feature of the interior of cells) was not real: an artefact, an illusion. Every Monday afternoon it was the custom for the whole department to listen to a research talk by a visiting lecturer. One Monday, the visitor was an American cell biologist who presented completely convincing evidence that the Golgi Apparatus was real. At the end of the lecture, the old man strode to the front of the hall, shook the American by the hand and said – with passion – “My dear fellow, I wish to thank you. I have been wrong these fifteen years.” We clapped our hands red … In practice, not all scientists would [say that]. But all scientists pay lip service to it as an ideal – unlike, say, politicians who would probably condemn it as flip-flopping. The memory of the incident I have described still brings a lump to my throat.25
This is what people mean when they talk about science being ‘self-correcting’. Eventually, even if it takes many years or decades, older, incorrect ideas are overturned by data (or sometimes, as was rather morbidly noted by the physicist Max Planck, by all their stubborn proponents dying and leaving science to the next generation). Again, that’s the theory. In practice, though, the publication system described earlier in this chapter sits awkwardly with the Mertonian Norms, in many ways obstructing the process of self-correction. The specifics of this contradiction – between the competition for grants and clamour for prestigious publications on the one hand, and the open, dispassionate, sceptical appraisal of science on the other – will become increasingly clear as we progress through the book.
