Sexual Attractiveness: Waist not, want not

The book delves into the significance of the waist-to-hip ratio (WHR) as a reliable indicator of female health and fertility, challenging previous studies that relied on 2D representations. Utilizing innovative 3D stimuli, the research involved participants rating computer-generated female figures based on various attributes, revealing that a lower WHR (0.5) was consistently perceived as more attractive. The findings support evolutionary theory, highlighting WHR as an adaptive signal of health and reproductive potential, while also considering cultural influences on body perception.
