“Voice-Pitch Bias in Political and Economic Environments”
by
Özgür Kıbrıs
Sabancı University
Abstract
We present two studies that respectively analyze the implications of voice pitch in political and economic decisions. In the first study, we use an online experiment to analyze the relative effect on voter behavior of a candidate’s voice pitch and policy stance. We demonstrate a strong voice-pitch bias: between candidates who are identical in every other aspect, voters are more likely to choose the one with the lower voice-pitch, and more so in elections between men than women candidates. We then introduce a novel phenomenon: persistence of voice-pitch bias is the amount of policy difference needed to compensate for voice-pitch bias. While persistence is also gender-dependent, the effect is now reversed: voice-pitch bias is more persistent in elections between women than men candidates. As a possible mechanism, we show that voters perceive candidates with lower voice-pitch as more competent and trustworthy. The second study is an > ongoing project where we aim to experimentally analyze whether employers’ evaluation of current or potential employees is subject to a voice-pitch bias. If this is the case, we aim to measure the premium an employee receives/foregoes in response to a unit change in her voice pitch, the so-called voice-pitch premium. We present the design of our experiment as well as some preliminary findings from its first stage.
