RS 216 - Diana Fleischman on "Being a transhumanist evolutionary psychologist"

Release date: September 2nd, 2018

Diana Fleischman

On this episode of Rationally Speaking, professor Diana Fleischman makes the case for transhumanist evolutionary psychology: understanding our evolved drives, so that we can better overcome them. Diana and Julia discuss sexual preferences, jealousy, and other drives -- how immutable are they? How do we know? And how would it change society, if we could change the distribution of people we find attractive, or normalize new relationship structures such as polyamory?

Release date: August 5th, 2018

Anthony Aguirre

This episode features physicist Anthony Aguirre discussing Metaculus, the site he created to crowd-source accurate predictions about science and technology. For example, will SpaceX land on Mars by 2030? Anthony and Julia discuss details such as: why it's useful to have predictions on questions like these, how to measure Metaculus' accuracy, why Anthony chose not to run it like a traditional prediction market, and how to design incentives to reward good forecasters.
