Episode 140: Immunizing Stratagems

from The Theory of Anything · host Bruce Nielson and Peter Johansen

Ad hoc saves and immunizing stratagems are phrases Karl Popper used to describe moves humans make when we try to protect our theories from refutation. We all do this every day in one way or another.But immunizing stratagems hurts theories in that this move makes our ideas overall less convincing to other people. Marxism and psychoanalysis are the classic areas where Popper saw true believers bend over backward to save these theories from refutation from the real world. This was the main topic of The Myth of the Closed Mind by Ray Scott Percival, who we interviewed a few episodes ago. So when ideas come into contact with human minds, theories or memes that move us closer to truth have a survival advantage. So as flawed as we are, humans—all humans—cannot help but seek truth, fallibly of course. Bruce reads a lot from Ray’s book on this episode, especially from chapter 4, “Ideologies as Shapeshifters.” Please consider ordering Ray’s excellent book, which is also available on Audible. ⁠⁠⁠⁠⁠⁠⁠⁠Support us on Patreon⁠⁠⁠⁠⁠⁠⁠⁠
