Earlier this year I posted a bonus episode featuring contributions from students in my undergraduate seminar here at Basel University. It proved to be one of the more popular episodes of the podcast. This semester I taught a masters level class on the evolutionary psychology of mate preference and, again, gave the students the task of summarising the research papers they found most interesting for a special bonus episode. As before, most of the students are not native English speakers, nor have they recorded audio before. I am super grateful they agreed to be a part of the podcast (especially after I freaked them out by telling them how many people listened to the previous bonus episode!).

Is blonde and red hair attractive because of how it looks, or because it’s rare? Also, “my genes made me do it”: can men (or women) blame their cheating ways on their genetic inheritance? And we also continue last month’s foray into the murky world of mate-poaching, and discover the differences between the sexes when it comes to detecting potential partner pilferers.

Some have theorised that red and blonde hair is attractive because it is rare. New research by Zinnia Janif tests this idea. Image credit: qsimple on flickr.com

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.

Ryan Gosling, you bastard. One man who looks great whether clean shaven, stubbled, or heavily bearded. The rest of us look at our best when we're clean shaven. Or is that heavily bearded? Or stubbled? Barnaby Dixson clears it up in this special episode.

This month, is gaydar real? Can we tell whether a person is gay or straight, or even whether they adopt particular sexual roles, purely from their facial appearance? I talk to Konstantin Tskhay to find out. I also talk to Barnaby Dixson and discover what type of facial hair is the most attractive, and whether men with bushier beards make better fathers.

In HBO's new Liberace biopic, Behind the Candelabra, Matt Damon short circuits even the least sensitive gaydar. But does gaydar really exist? Maybe. New research by Konstantin Tskhay suggests that, not only can we tell if a person is straight or gay, we can even accurately guess their preferred sexual role.

I speak to Tyler Stillman of Florida State University about whether we can identify violent criminals just by looking at their faces. We also find out whether electoral candidates who appear more powerful or trustworthy can expect more votes, and how a woman's menstrual cycle can affect her preferences for hairy men.

I talked this month about Francis Galton, pioneer physiognomist and creator of composite portraiture. That's when you combine two or more facial photos into a single image. His photography skills are pretty amazing when you consider that he was working 125 years ago and was able to come up with some convincing results.

Francis Galton's composites of violent criminals. The images on the top are the real criminals, and the ones on the bottom are composites.

The image above shows images of Gordon Brown (a), that have been composited using Galton's method (b) and the modern method (c). In Galton's method, the images are rotated and scaled so that the eyes lie on top of each other before being combined. In the modern, computerised method, the locations of over 150 points are averaged before the images are combined. This gives a much clearer image. Galton's more primitive method could explain why he failed to find a 'criminal type', or it could just be because criminals don't look that different to everybody else.

Physiognomy is currently undergoing a resurgence, although most researchers study whether attractiveness, or personality traits such as trustworthiness, can be detected from faces. Perhaps because physiognomy is so closely associated with Galton, who founded eugenics and held typically 19th century views on race, attempts to extend study into areas such as criminality are often met with some resistance.
