Episode 51: Was Karl Popper Dogmatic?

There seems to be broad agreement, even among Karl Popper's own students, that he was a deeply dogmatic individual. In this episode we ask the question 'Was Karl Popper Dogmatic?' by reviewing a humorous article in Scientific American by John Horgan on August 22, 2018. Along the way, we discuss by what means we judge dogmatism. How do we even tell if someone is dogmatic or not? Is there a litmus test for dogmatism? If so, what is it?  Link to John Horgan's article.
