Looks aren't everything: How attractive you are is down to voice and smell tooVoice and smell also play a huge role, scientists have said and this needs to be taken into consideration when designing psychology studies. "Recently, most reviews have focused on visual attractiveness for example, face or body attractiveness," explained Agata Groyecka, lead author of a review published on the subject in the journal Frontiers in Psychology. In her paper, the researcher from the University of Wroclaw in Poland analyses thirty years of scientific research, to identify studies that centred on the role of vocal and olfactory factors.
