From The Wall Street Journal, How Science Lost the Public’s Trust, by Tunku Varadarajan:
The politicization of science leads to a loss of confidence in science as an institution. The distrust may be justified but leaves a vacuum, often filled by a “much more superstitious approach to knowledge.” To such superstition Mr. Ridley attributes public resistance to technologies such as genetically modified food, nuclear power—and vaccines.
“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.”
He notes that WHO’s primary task is forestalling pandemics. Yet in 2015 it “put out a statement saying that the greatest threat to human health in the 21st century is climate change. Now that, to me, suggests an organization not focused on the day job.”
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. It’s sure to be a costly divorce.
When you trust nothing you will believe anything.
