Episode notes

In recent years it's been found that results which people took to be secure in textbooks don't replicate. This prompted a strong reaction from the scientific community and social sciences statistics especially. It also led to a bunch of problems being uncovered with the way science was done or these things which people were pretty clear could be improved upon. Now this is a sort of quite broad reform movement sweeping through to social sciences which is trying to address the problems that I've identified.

Everybody talks about the truth, but nobody does anything about it. And to be honest, how we talk about truth — what it is, and how to get there — can be a little sloppy at times. Philosophy to the rescue! I had a very ambitious conversation with Liam Kofi Bright, starting with what we mean by “truth” (correspondence, coherence, pragmatist, and deflationary approaches), and then getting into the nitty-gritty of how we actually discover it. There’s a lot to think about once we take a hard look at how science gets done, how discoveries are communicated, and what different kinds of participants can bring to the table.
