New research shows that the sound of a person’s voice alone can help reveal if a person has cheated on a partner.
In this research, both men and women simply had their voices recorded while counting from 1 to 10. Half of the speakers had cheated on a partner while the other half had not. Other participants were asked to rate the voices and evaluate whether the person speaking engaged in some type of infidelity. The participants were able to more accurately identify cheaters by simply listening to the sound of a person’s voice. The research took into account a wide range of factors that may have influenced the results such as a speaker’s attractiveness, body composition, and weight. It’s not clear exactly how listeners made their judgements — it’s not clear what aspects of a person’s voice reveal the tendency to cheat. The research simply shows that the tendency to engage in infidelity is somehow conveyed through the sound of a person’s everyday voice.
