      Falsificationism falsifies itself: it is a theory scientists refuse to abandon despite mountains of observations that falsify it

      (Falsificationism is the theory that scientists abandon a theory when they find evidence against it. This essentially never happens.)

      Agree about the sociology of science here, but to me falsification is about the conditions under which knowledge grows.

      Falsification is the ideal towards which science (and scientists) should strive. Whether they live up to it is a secondary question.

      I think the actual issue is whether a group is open to the possibility of adopting an alternative theory—not “falsification” as such.

      The processes by which an epistemologically sane group considers & eventually adopts a better theory are complex, >

      and are, empirically, not well-described by falsificationism.

      isn't it driven by "weight of evidence" in some sense? Don't you think any formalism ever captures this reasonably well?

      Falsificationism considers a single theory in isolation. A weight of evidence theory is about comparing two theories.

          So you disagree with Deborah Mayo then? Shouldn't we ever abandon a theory without something ready to turn to?

          I think we sometimes should. But falsificationism is the claim that scientists actually do [they don’t] or always should [usually wrong].
