In an election season, prospective voters take their impressions of the candidates not only from what they say but also on the basis of other aspects of their presentation, such as intonation, gestures, and appearance. Recent studies have identified another trait that contributes subtly but significantly to voters’ impressions: the pitch of a candidate’s voice. In “How Voice Pitch Influences Our Choice of Leaders” political scientist Casey Klofstadt and biologists Stephen Nowicki and Rindy Anderson describe their interdisciplinary research, which attempts to weigh the effect of a high- or low-pitched voice on a candidate’s electoral success.
