This month, why seeing red might have less to do with anger than attraction. We also discover if opposites attract when it comes to bodyweight, and find out how the way you walk is tied to your hormones.

If 14 minutes of me blathering on isn't enough for you, I gave an extended interview to Jose Drost-Lopez of Psychtalkradio.com this month. You can download a podcast of that interview here.

An experiment that shows we really do like what we see. Also, how voices can cycle from attractive to unattractive and back again, and why you’re more likely to remember a fish if you see it next to an attractive man’s face. Yep, that's not a typo...

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.
