From the WSJ:
“Conformity,” Mr. Ridley says, “is the enemy of scientific progress, which depends on disagreement and challenge. Science is the belief in the ignorance of experts, as [the physicist Richard] Feynman put it.”
Mr. Ridley reserves his bluntest criticism for “science as a profession,” which he says has become “rather off-puttingly arrogant and political, permeated by motivated reasoning and confirmation bias.” Increasing numbers of scientists “seem to fall prey to groupthink, and the process of peer-reviewing and publishing allows dogmatic gate-keeping to get in the way of new ideas and open-minded challenge.”
In Mr. Ridley’s view, the scientific establishment has always had a tendency “to turn into a church, enforcing obedience to the latest dogma and expelling heretics and blasphemers.” This tendency was previously kept in check by the fragmented nature of the scientific enterprise: Prof. A at one university built his career by saying that Prof. B’s ideas somewhere else were wrong. In the age of social media, however, “the space for heterodoxy is evaporating.” So those who believe in science as philosophy are increasingly estranged from science as an institution.
