You may think you’re casting your vote for the candidate that best represents your political, economic and social views, but it could be something else that attracts you to that individual: the tenor of his or her voice. Voters prefer candidates with a deeper voice, according to a study from the University of Miami and Duke University. This isn’t a new finding. Previous research has shown that the pitch of a person’s voice can strongly influence how he or she is perceived by others. But how does the human voice affect how we choose our leaders? After listening to the recordings, research volunteers were more likely to “vote” for the candidate with the deeper voice. And this held true whether the speaker was a man or a woman. In fact, women with lower voices were perceived to be stronger, more trustworthy and more competent than those whose voices were higher.
