Politicians With Deeper Voices Win More Votes, Study Suggests

According to a new US study, candidates who have deeper voices are more likely to win over political elections.

Two biologists together with a political scientist examined the association of voice pitch on voter's preferences. Rindy Anderson, a biologist of Duke University, Durham, in North Carolina stated in their study that our voices influence more than the words we utter.

"We often make snap judgments about candidates without full knowledge of their policies or positions. These findings might help explain why." Anderson said.

This may suggest why only a few women get elected to higher positions in politics.

Earlier studies revealed a strong link between the pitch of a human voice as to how the speakers are perceived. However, little information supports the association between pitch and the voter's way of selecting political leaders.

Together with Casey A. Klofstad, a political scientist at the University of Miami and colleague Susan Peters, the team went on to determine the answer to this question.


First, the team recorded men and women saying:

"I urge you to vote for me this November."

Then digitally manipulated the voices into higher and lower pitches.

Volunteers from both universities were then invited to listen to the modified versions and then cast a vote for either of the two pitches.


The results revealed that both sexes selected male and female voices with lower pitches.

"These findings suggest that men and women with lower-pitched voices may be more successful in obtaining positions of leadership. This might also suggest that because women, on average, have higher-pitched voices than men, voice pitch could be a factor that contributes to fewer women holding leadership roles than men," concluded the authors.
