The researchers used a 3D optical scanner to create detailed images of the body shape of 77 volunteers. Among them 40 were male and 37 were female.
The results of the scan were shown to a separate group of 87 volunteers who were asked to rate their attractiveness. A majority of them responded by saying symmetric bodies were more attractive than asymmetric ones.
"The 3D body scanner accurately extracts hundreds of measurements of the human body, including volume, in six seconds and removes a potential source of measurement error, the human experimenter," said lead author Dr William Brown.
