Guilty of infidelity? Try to keep your mouth shut
People can reliably spot someone who has betrayed a partner just by listening to them speak: study
Apparently all we needed to determine that Jay-Z had indeed cheated on Beyoncé was a sample of the rapper counting from one to 10.
According to a recent study published in Evolutionary Psychology — “Your Cheatin’ Voice Will Tell on You: Detection of Past Infidelity From Voice” — undergraduate students could accurately assess whether someone had cheated on their committed romantic partner just by listening to a recording of their voice.
The study notes that a person’s voice can communicate a lot of information about them, irrespective of the content: a person’s sex, race, social status, personality traits — even their height and weight and whether their body or face is symmetrical — can all be deduced by voice alone. “Voices relay important information pertaining to mating success and sexual behaviour,” the study says.
Knowing how revelatory voices can be, Susan M. Hughes, a psychology professor at Albright College in Pennsylvania, delved into a database she had of voices counting from 1 to 10. Hughes and her fellow researcher, Marissa A. Harrison, asked study participants to listen to samples of 10 women’s and 10 men’s voices.
“Half of the speakers for each sex reported that they had sexual intercourse with a person outside of a previous or current, exclusive and committed relationship at some point in their lives (i.e., were ‘cheaters’), and the other half reported never cheating on their partners,” the study noted.
To ensure that the voice samples were as similar as possible, all of the voices used were from people who reported being heterosexual, white, unmarried and in a committed romantic relationship. The researchers created two versions of each voice recording — a higher-pitch version and a lower-pitch version — to determine whether pitch played a role in how these voices were perceived. Participants then rated the voices on a scale of one (not at all likely to cheat) to 10 (very likely).
These were voices of strangers the participants didn’t know, with no content about their relationships being revealed, just a voice counting from one to 10. And yet those recordings revealed volumes about their personal lives.
“We found that participants indeed rated the voices of those who had a history of cheating as more likely to cheat,” the researchers reported. Even when the speakers’ pitch was manipulated, it didn’t seem to play a factor — except for the lower-pitched female voices, which men rated as more likely to cheat. (This could be because low female voices are perceived as sexier or more flirtatious, Hughes said in a phone interview.)
Women were influenced by perception as well; they were more likely to rate men as being untrue to their partners, but weren’t necessarily more accurate in those estimations. This might be because women are more suspicious of men than men are of women, the study noted; men also are more likely to self-report having cheated on a partner.
The study’s researchers couldn’t determine why humans are so good at reading one another’s voices, just that we are.
Interesting stuff, but how does this study relate to real life? Because voices contain so much information about a person, Hughes recommends always speaking to a romantic prospect before meeting up that first time. “It would be fine to be a blind date, but don’t go on a deaf date,” Hughes says.
And, yes, going on a first date where you matched online and made all the arrangements via text qualifies as a “deaf date.”
