Deep voices can sway voters

The depth of a political candidate's voice can have an impact on whether or not people choose to vote for them. This is the suggestion of new research published in the journal Proceedings of the Royal Society B: Biological Sciences, which revealed individuals often prefer politicians with lower-pitch tones.

Investigators from the University of Miami and Duke University observed the findings could have serious implications for females who are aiming to hold positions of power in the political world.

According to the investigation, both men and women with deeper voices were thought of as being more trustworthy, competent and stronger than those who speak in higher pitches.

Casey Klofstad, Associate Professor of Political Science in the College of Arts and Sciences at the University of Miami - which was established in 1925 - noted the research was the first to look at the voices of both men and women hoping to head into office.

The expert noted: "Only men perceive lower pitched male voices to be more competent and stronger."

Dr Ashley Weinberg, a Chartered Psychologist and Senior Lecturer in Psychology at the University of Salford, commented: "The power of how we speak is often underestimated, but this research clearly bears out the potential for influential paralinguistic messages to be conveyed to audiences.

"There has been work to show that we are fairly accurate at judging a whole range of things about a person from their voice, including their sexual history, so clearly our instincts for picking up social messages, such as who might make a good leader, are finely attuned.

"The test is whether such messages appeal to all voters and whether this determines actual election outcomes."
