In this month's episode we look at sexuality: why do people who identify as straight sometimes hookup with partners of the same gender? We'll also find out if straight men prefer women who are attracted to other women. This episode also features an interview with Sydni Huxman of Kansas State University, who presented her research on backup partners at the recent HBES conference.

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!).

In a belated attempt to understand the results of the recent US elections, we harness the power of attractiveness psychology (because polling doesn't seem to work). Do we vote for candidates based on their voices? Is our party political preference linked to our sexual behaviour? We find out in this month's show.

With gay marriage now legal in the USA (not to mention, Sweden, New Zealand, Uruguay, and the Pitcairn Islands), let’s look at how same-sex attraction develops during adolescence. Is same-sex attraction stable during teenage years, and what are lesbians’ first memories of same-sex attraction?

A graph illustrating Plant's finding that people who are especially worried about being perceived as gay (high contagion) and who undergo a mating prime (being made to think about romantic partners) are more likely to express anti-gay attitudes. Note that warmth is lower amongst both the high contagion group and the mating prime group, but that it is only very low amongst those who are high contagion AND mating primed.

Pazhoohi and Hosseinchari reported this month that men find women who wear a full veil (chador) are less attractive than women who wear clothes that don't conceal the body. But does the effect depend on the body shape of the wearer, or whether men judge women's attractiveness for a long- or short-term relationship?

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.

When adult movie star Mary Carey stood for election as governor of California, it seemed more than a little bizarre (even when she lost to a cyborg bodybuilder). But new research by Markey and Markey shows that politics and porn might be more closely linked than even Carey had considered.
