Yale study reveals class bias among hiring managers
The study shows how speech patterns give away a person's income, education, and occupation status.
A Yale University study has found that recruiters and hiring managers tend to favour job candidates from higher social classes. The research is based on five separate studies, four of which examine the extent that people accurately perceive social class based on a few seconds of speech. Michael Kraus, assistant professor of organisational behaviour at the Yale School of Management co-authored the paper and says a person's speech patterns shape the way people perceive them, including assessing their competence and fitness for a job.
"While most hiring managers would deny that a job candidate's social class matters, in reality, the socioeconomic position of an applicant or their parents is being assessed within the first seconds they speak - a circumstance that limits economic mobility and perpetuates inequality,” he says, adding that they found that reciting seven random words is sufficient to allow people to discern the speaker's social class with above-chance accuracy.
The study, which is to be published in the Proceedings of the National Academy of Sciences, demonstrates that people can accurately assess a stranger's socioeconomic position - defined by their income, education, and occupation status - based on brief speech patterns.
The fifth study examined how these speech cues influence hiring. Twenty prospective job candidates from varied current and childhood socioeconomic backgrounds were recruited from the New Haven community to interview for an entry-level lab manager position at Yale. Prior to sitting for a formal job interview, the candidates each recorded a conversation in which they were asked to briefly describe themselves. A sample of 274 individuals with hiring experience either listened to the audio or read transcripts of the recordings. The hiring managers were asked to assess the candidates' professional qualities, starting salary, signing bonus, and perceived social class based solely on the brief pre-interview discussion without reviewing the applicants' job interview responses or resumes.
The hiring managers who listened to the audio recordings were more likely to accurately assess socioeconomic status than those who read transcripts, according to the study. Devoid of any information about the candidates' actual qualifications, the hiring managers judged the candidates from higher social classes as more likely to be competent for the job, and a better fit for it than the applicants from lower social classes. Moreover, they assigned the applicants from higher social classes more lucrative salaries and signing bonuses than the candidates with lower social status.
"We rarely talk explicitly about social class, and yet, people with hiring experience infer competence and fitness based on socioeconomic position estimated from a few second of an applicant's speech," says Michael.
"If we want to move to a more equitable society, then we must contend with these ingrained psychological processes that drive our early impressions of others. Despite what these hiring tendencies may suggest, talent is not found solely among those born to rich or well-educated families. Policies that actively recruit candidates from all levels of status in society are best positioned to match opportunities to the people best suited for them."
