      YEP. I see weird deficits in causal thinking (and deductive thinking more generally) when I talk to biologists and biotech people who weren't trained in math/physics/CS.https://twitter.com/dallandrummond/status/1108556522467086336 …

      This bizarre belief that establishing causality requires uncovering the mechanism is one of the most progress-inhibiting misconceptions in science. Establishing causality requires only controlled perturbations — you need not know anything about mechanism. +1 @kph3k pic.twitter.com/lIZ7Eorc4E

      In the science-fiction novel "The Three-Body Problem", all the "scientist" characters seem to think they can't draw inferences about a system unless they can characterize how every part of the system works. The only character who deduces anything is a cop.

      Real science is not saying "more research is needed" until every conceivable part of a system is mapped. It's knowing which conclusions you can draw -- and *can't* draw -- from the always limited data available.

      Sometimes that means you can draw a practical conclusion -- "this intervention improves this outcome" -- without knowing how it works!

      Sometimes I wonder if the awesome powers given to us by molecular biology -- genomics, transcriptomics, proteomics, etc -- have trained some to believe that biology is like a coloring book where you're not "done" till every piece is colored.

      Replying to @s_r_constantin

      Would argue this is a result of doing biology. Every molecular biologist has had dozens of failed hypotheses based on what appeared to be sound logic at the time, that turned out to be bullshit, because most of the time biology isn't very logical.

      Replying to @halvorz @s_r_constantin

      Causal inference in biology is *hard,* much harder than in physics. In some cases it may be easier, but there is a certain amount of learned helplessness, based on brutal experience. We don't trust mechanism free hypotheses, because even *with* a mechanism our hypotheses fail.

          all subjects more complex than biology are actually impossible i'm only half joking
