Finally, something women and men can agree on together–both genders prefer leaders with masculine voices.  The research comes from Rindy Anderson (Duke University) and Casey Klofstad (University of Miami), and was published in PLOS ONE.

…the researchers asked people to listen to the phrase “I urge you to vote for me this November” spoken by two voices that differed only in their pitch. They found that both men and women preferred female candidates with masculine voices. Men also preferred men with masculine voices but women did not discriminate between the male voices they heard. According to the authors, their results suggest that the influence of voice pitch on perceptions of leadership capacity is consistent across different domains of leadership and independent of social context.

“We often do not consider how our biology can influence our decision making,” Klofstad said. “The results of this study show that voice pitch–a physiological characteristic–can affect how we select our leaders.”

Why, then, do both genders prefer leaders with masculine voices?

“In the case of women’s voices, this bias could be a consequence of lower-pitched female voices being perceived as more competent, stronger, and more trustworthy,” the authors wrote in the study. “That is, these traits are perceived as positive in the context of leadership and could be the mechanism that leads us to prefer female leaders with lower voices. Additionally, the pitch of the female voice declines over the lifespan. Consequently, selection of female leaders with lower-pitched voices can result in the selection of women who are older, and perhaps more experienced at leading others. Stated differently, men and women may be biased to select older women as leaders, regardless of the type of position in question. In the case of men’s voices, men with lower-pitched voices are larger, stronger, and more aggressive. Again these traits are perceived as positive in the context of leadership, leading us to prefer male leaders with lower voices.”

Knowing this, would you change your vocal pitch to sound more like a leader?
