The risk factors for rape: is sexual assault indiscriminate or are some women at greater risk than others? I speak with Carin Perilloux to find out.

The Slut Walks that were held worldwide earlier this year demonstrate that advice about how women might avoid sexual assault is often unwelcome, especially if it focuses on changing women's behaviour. However, as Carin Perilloux told me in this month's interview, "it should be presented as 'here is all the information; you're educated women, you can make your own choices, you decide what you want to do.'" Listen in to discover more about Carin's research on the risk factors for rape.

In this special episode I talk with biological anthropologist Mark Shriver, Nanjala Nyabola, an Oxford graduate student who wrote a comment piece for the Guardian about Kanazawa's article, and psychologists Scott Barry Kaufman and Jelte Wicherts, who blogged about the controversy here and here and also reanalysed the original data. You can read Kanazawa's blog post here.

Georgia O'Keeffe's "Black Iris III". Rudski showed pictures by O'Keeffe to women when they were in the fertile and non-fertile phases of their menstrual cycle. 31% of fertile women interpreted the pictures as sexual, but only 9% of non-fertile women saw the sexual double-meaning (for the record, O'Keeffe herself always denied her art had sexual connotations. She would say that, though, wouldn't she?).
