We continue our discussion of ⁠Dwarkesh Patel's article "Contra David Deutsch on AI"⁠ compared to ⁠Brett Hall's tweet on IQ theory⁠. This time we concentrate on criticisms of Brett Hall's theory.  Along the way, we ask the ultimate question: Why did Karl Popper make his epistemology specifically about refuting empirical scientific theories instead of just generalizing it (like Deutsch does) to criticizing all theories and ideas? And why is this important? And then, we talk about how much we really like Brett's theory. --- Support this podcast: https://podcasters.spotify.com/pod/show/four-strands/support
