Internet dating and ethnicity, with Melinda Mills; selfies and self-esteem. 29 Dec 2015

I recently attended the Galton Institute's conference on mate choice, and was lucky to grab an interview with Prof. Melinda Mills, head of The University of Oxford's Department of Sociology. We spoke about Melinda's research on ethnicity and internet dating, why attitudes to migration shape who we are willing to date, and discussed some of the difficulties inherent in studying dating preferences on the web. I also talk about some new research on selfies and who takes them.

The images Alex and I mentioned in the show

Richard Russell's "The Illusion of Sex" placed third in the 2009 Illusion of the Year Contest. Most people perceive the face on the left as female, and the face on the right as male. In fact, the photographs show the same face (a computer-generated androgynous face): the only difference is that the contrast of the face on the left is higher than the that of the face on the right. The effect is so strong, it is difficult not to see a woman and a man.

A figure from Alex's paper. The white lines encircle the 'features' (eye, eyebrow, and mouth) and the black lines the surrounding areas. It was the contrast between the features and the surrounding skin that Alex measured. He confirmed that facial contrast is higher in women than in men. His other research showed that women exaggerate these sex differences with make up.

This figure is from the Lewis paper, and shows how he manipulated back curvature. Men preferred a curvature of around 45 degrees. Listen in to find out why.

Penis size, with Brian Mautz; eat fruit to get a tan. Aug 2014

Stay out of the sun! New research suggests that the skin colour change associated with sun tanning isn't as attractive as the effects of eating carotenoid-rich fruits and vegetables, like tomatoes, pumpkins, and spinach. Can an attractive personality make you appear more attractive? And we find out why when women see red, women see red.

Plus, as a special summer surprise, Hannah Rowland of the Behavioural Ecology and Evolution Podcast interviews Brian Mautz at the ISBE2014 conference about his research on penis size and attractiveness.

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.
