Episode 50! An extended interview with Barnaby Dixson of the University of New South Wales. We discuss research on facial hair and attractiveness, both Barnaby's own work and the wider research area. We cover the evolution of facial hair, the history of facial hair research, detail some of the ways Barnaby works to control confounding variables in his experiments, and find out whether researching facial hair has made Barnaby more or less likely to cultivate his very own chin warmer.
