From The Wall Street Journal, How Science Lost the Public’s Trust, by Tunku Varadarajan:

He asks: “If you think biological complexity can come about through unplanned emergence and not need an intelligent designer, then why would you think human society needs an ‘intelligent government’?” Science as an institution has “a naive belief that if only scientists were in charge, they would run the world well.” Perhaps that’s what politicians mean when they declare that they “believe in science.” As we’ve seen during the pandemic, science can be a source of power.

But there’s a “tension between scientists wanting to present a unified and authoritative voice,” on the one hand, and science-as-philosophy, which is obligated to “remain open-minded and be prepared to change its mind.” Mr. Ridley fears “that the pandemic has, for the first time, seriously politicized epidemiology.” It’s partly “the fault of outside commentators” who hustle scientists in political directions. “I think it’s also the fault of epidemiologists themselves, deliberately publishing things that fit with their political prejudices or ignoring things that don’t.”

One motivation: Pessimism sells. “You don’t get blamed for being too pessimistic, but you do get attention. It’s like climate science. Modeled forecasts of a future that is scary is much more likely to get you on television.” Mr. Ridley invokes Michael Crichton, the late science-fiction novelist, who hated the tendency to describe the outcomes of models in words that imply they are the “results” of an experiment. That frames speculation as if it were proof.
