Evidence from Meta-Analyses of the Facial Width-to-Height Ratio as an Evolved Cue of Threat.
The facial width-to-height ratio (FWHR) is the width of the face divided by the height of the upper face.There is mixed evidence for the hypothesis that the FWHR is a cue of threat and dominance in the human face.We conducted a systematic review and meta-analyses of all peer-reviewed studies (and 2 unpublished studies) to estimate the magnitude of
