The study by University of Chicago Booth School of Business found that when hypothetical employers and professional recruiters listened to or read job candidates' qualifications, they rated the candidates as more competent, thoughtful and intelligent when they heard the pitch than when they read it - even when the words used were exactly the same.
As a result, they liked the candidate more and were more interested in hiring them.
However, the addition of video did not influence evaluations beyond hearing the candidate's voice, said Professor Nicholas Epley who conducted the study with PhD candidate Juliana Schroeder.
"In addition to communicating the contents of one's mind, like specific thoughts and beliefs, a person's speech conveys their fundamental capacity to think - the capacity for reasoning, thoughtfulness and intellect," said Epley.
In a series of experiments, the researchers asked a group of Chicago Booth MBA student job candidates to develop a short pitch to the company for which they would most like to work. They created written pitches and spoken pitches (videotaped).
In an initial experiment, a separate group of evaluators judged the spoken pitches by either watching and listening to the video recording, listening to the audio only, or reading a transcript of the pitch.
The evaluators who heard the pitch subsequently rated the candidate as more intelligent, thoughtful and competent than the evaluators who only read a transcript of the pitch; the evaluators who watched the video pitch did not rate any differently than those who heard the pitch.
In fact, evaluators who heard the pitch reported liking the candidate more and reported being significantly more likely to hire that person.
The study will be published in The Journal of Psychological Science.
