Correlation, causation – and reason for precaution

“Correlation is not the same as causation.” This is a core catechism that is drilled into most of us scientists, along with “I might be wrong,” and “build your competitive science reputation by demolishing the half-baked work of others.”

Alas, “Correlation is not the same as causation” has become an incantation parroted by Fox-Watchers, as part of the Murdochian campaign to undermine science and claim that nothing can ever be proved. In fact, sifting for correlations is how experimental science begins. A strong correlation demands: “hey, check this out!”

But it’s more than that. A strong correlation shifts the Burden of Proof. When we see a strong correlation, and the matter at-hand is something with major health or safety or security implications, then we are behooved to at least begin taking preliminary precautions, in case the correlation proves to be causative. Sometimes the correlation is later demonstrated not to be causal and a little money has been wasted. But this often proves worthwhile, given long lead times in technology.

For example, we were fortunate that work had already begun on alternative refrigerants to CFCs, when their role in ozone damage was finally proved. Indeed, valid concerns over the health and environmental effects of tobacco and leaded gasoline were dismissed for years. Two must reads: Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming by Naomi Oreskes and Erik Conway, as well as the story of Clair Patterson and the obstructionism of the oil industry.

Another example: terrorism experts sift for correlations and apply intelligence resources to follow up, while giving potential targets cautious warnings. Many correlations don’t pan out. But a burden falls on those saying “ignore that.”

Parse this carefully. Strong correlation demands both closer examination and preliminary precautions.

But the underlying narrative of the crazy, anti-science right is: “Correlation is not the same as causation… and any ‘scientist’ who talks about a correlation can thus be dismissed as a fool. And since that is most of science, this incantation lets me toss out the whole ‘science’ thing. Yippee!”

Those who spout this incantation aren’t all fools, but you can tell by watching to see if they follow “Correlation is not the same as causation” with… curiosity! And acceptance of both precaution and burden of proof. Those who do that are “Skeptics” and welcome to the grand, competitive tussle known as science.

Those who use “Correlation is not the same as causation” as a magic incantation to dismiss all fact-using professions are fools holding a lit match in one hand and an open gas can in the other, screaming “one has nothing to do with the other!”

See my earlier list of examples  – including well-justified concerns over tobacco, smog and leaded gasoline – where this and other incantations delayed the proper application of science to public policy, leading to hundreds of thousands… maybe millions… of deaths worldwide.

Another central mythos: We all know that:  “Just because someone is smart and knows a lot, that doesn’t automatically make them wise.”

It’s true. But in the same way that Suspicion of Authority is wholesome, till it metastasizes, this true statement has been twisted into something cancerous:  “Any and all people who are smart and know a lot, are therefore automatically unwise.”

The first statement is true and we all know it. The second is so insanely wrong that anyone believing it is hence a stark, jibbering loony. And yet, the latter is now a core catechism of the confederacy, because they have been allowed to leave it implicit.

Of course, blatantly, the average person who has studied earnestly and tried to understand is wiser than those who deliberately chose to remain incurious and ignorant. When cornered, even the most vehement alt-righter admits that. But cornering them takes effort and – above all – careful parsing of the meme. It is a logical corner they’ve painted themselves into! But their memes are slippery.

Suspicion and distrust – of universities and smart people, as well as of people with knowledge and skill — now extends from the war on science to journalism, teaching, medicine, economics, civil servants… and lately the “deep state” conspiring villains of the FBI, the intelligence agencies and the U.S. military officer corps. This is bedlam. It is insanity that serves one purpose, to discredit any “elites” who might stand in the way of a return to feudalism by the super rich, which was the pattern of 6000 years that America rebelled against.

We need to be more proactive and tactically effective in fighting back against these agents of darkness and promoters of feudalism. There are clever shills who get rich providing incantations against science and other fact-professions.  We must show every uncle and aunt who parrots this nonsense how they have been hoodwinked. That is where phase 8 of the American Civil War will be won, in the trenches, getting one friend at a time to snap out of the hypnotics spells…

… by using evidence and logic and compassion to draw our neigjhbors back to a nation of progress and science and pragmatic accountability and hope for an ever-better future.
