Ep 162: Steven Pinker’s ”Rationality” Chapter 7 ”Hits and False Alarms” Part 1

Here we consider whether when collecting data we are able to distinguish between the signal (hits) and noise (false alarms). I make the case the author early on is doing a good job of explaining "random error" when conducting experiments. However, broadly speaking this is an issue of increasing precision in our measurements. No mention seems to be made, crucially, in understanding the possibility of systematic error (a problem for accuracy). How do precision and accuracy differ? Why won't repeating our experiments and collecting more data help guard against certain kinds of errors? All this and more discussed in this episode.

Om Podcasten

This is a podcast primarily about the work of philosopher and physicist David Deutsch and related matters (such as Popperian epistemology). I read from and comment upon the books ”The Beginning of Infinity” & ”The Fabric of Reality” (both by Deutsch), ”The Science of Can & Can’t” (by Deutsch’s collegue Marletto) and ”Rationality” by Pinker (so far). In addition I make stand alone episodes about topics like resources, environmentalism, economics, science, philosophy, epistemology (especially explanations) and reason broadly.
