Science, Schmience

From Paul Krugman’s newsletter:

. . .  I’ve sometimes regretted having gone into economics, a field in which getting the story right all too often offends powerful players, who in turn intervene to prop up zombie ideas that should have died long ago.
 
But I also realized some time back that politics can and will intrude into any area of scholarly research where some people have strong motivations for getting the story wrong. This has obviously been the case for climate research, where an overwhelming scientific consensus has had to struggle against a whole industry of climate denial, which is almost entirely supported by fossil-fuel interests and has effectively taken over the Republican Party.
 
In fact, in some ways the climate scientists have had it worse than the economists; mainstream Keynesian economists (which is pretty much what I am) get a lot of abuse, but as far as I know none of us has had politicians trying to criminalize our work, the way Ken Cuccinelli, now a top official at the Department of Homeland Security, did to climatologist Michael E. Mann [ten years ago].
 
I used to think, however, that climate change was a subject uniquely vulnerable to anti-science propaganda and intimidation. After all, the effects of greenhouse gas emissions are invisible and gradual, taking decades to unfold; it’s always possible to mock the science because it happens to be snowing today, while accusing the scientists of taking jobs away from salt-of-the-earth coal miners.
 
Surely, I thought, it wouldn’t be that easy to politicize a science, to claim that all the experts were part of a vast conspiracy, in an area in which experts’ predictions could be validated and the conspiracy theorists revealed as phonies in a matter of weeks.
 
But I was wrong.
 
Epidemiology, like climatology — or for that matter economics — involves trying to model complex systems, so that no prediction ends up being exactly right. And the chains of cause and effect are long enough that the consequences of bad policy take some time to become completely apparent: Florida began reopening in early May, but Covid-19 deaths didn’t spike until July.
 
But we’re talking about weeks, not decades, and the story of the coronavirus is as clear as such things ever get.
 
Experts warned that a rush to resume business as usual, without social distancing and widespread use of face masks, would lead to a surge in new cases. The usual suspects on the right dismissed these concerns, insisting either that Covid-19 was a hoax or that its dangers were being greatly exaggerated by scientists who wanted to bring down Dxxxx Txxxx. Sunbelt states decided to believe the skeptics, not the scientists — and the result was a huge, deadly viral surge.
 
So that put an end to the politicization, right? Wrong. Not only are Txxxx officials still pressuring health experts to minimize the dangers, the top communications official at the Department of Health and Human Services accused his own agency’s scientists of “sedition.”
 
The moral here is that there’s no such thing as a safe subject when you’re dealing with people who have a totalitarian mind-set — and that is, in fact, what we’re dealing with. I suspect that in the early days of the Soviet Union plant geneticists imagined that they were working in a low-risk field; I mean, who would politicize that? In the end, however, thousands of them were sent to labor camps or executed for questioning the theories of Trofim Lysenko, a quack who somehow became one of Stalin’s favorites.
 
The fact of the matter is that we’re now struggling over where there’s even such a thing as objective truth. And staying out of politics is no longer an option for anyone.
 
Unquote.
 
I wouldn’t say we’re struggling over whether there’s objective truth. It’s real. What we’re struggling with are people who don’t respect it (like the chairman of the Republican Party who claimed that Biden’s record on the virus is worse than Txxxx’s). But Prof. Krugman is right about not staying out of politics. Voting — and supporting candidates in other ways — matters.
 
Which reminds me. Has anybody seen my Biden/Harris lawn sign? It still hasn’t been delivered. Maybe the crooked Postmaster General arranged for it to be confiscated?
