Vocal characteristics of presidential candidates can predict the outcome of actual elections

During political elections, voters rely on various cues that signal good social leadership, such as indicators of physical strength and masculinity. In adult men, masculine traits are related to testosterone levels, and one of those traits is low-pitched voice. Hence, lower pitch in a presidential candidate may be related to the election's outcome. This prediction is supported by experimental evidence showing that people prefer to vote for a candidate with a low- pitched voice. The aim of this study was to investigate the relationship between presidential candidates' vocal characteristics and actual election outcomes in 51 presidential elections held across the world. After analysis of the voices of opposing candidates, results showed that winners had lower-pitched voices with less pitch variability. Moreover, regression analysis revealed an interaction effect of voice pitch and voice pitch variability on the election outcome. Candidates with lower-pitched voices had greater likelihood of winning the election if they had higher pitch variability. This study extends previous findings, shows the importance of assessing vocal characteristics other than voice pitch, and offers external validity for the experimental evidence that candidates' vocal characteristics are related to the election outcome.
