Popular selection methods such as the traditional resume and unstructured interviews are susceptible to the influence of personal biases in evaluating applicants. This promotes inequality of opportunity. It was investigated whether a more objective letter selection and structured interviewing can lead to greater equality of opportunity for ethnic-culturally diverse applicants. More objective and structured selection methods include job requirements and questions that are relevant to the position, determined in advance based on a job analysis. More than two hundred HR professionals from different sectors and regions participated in the research.
The researchers conclude that objectifying and structuring selection methods helps to increase equality of opportunity for all’applicants, regardless of their migration background. This is caused by reducing random noise. For example, noise can arise if an assessor is distracted by something that reduces agreement between all the assessors. Objectification and structuring also reduces systematic differences between assessors in their assessments. Reducing noise and bias improves selection decisions.
Previous scientific meta-studies show that structuring the job interview also improves the prediction of work performance. Structuring therefore not only promotes equality of opportunity but also the predictive power of the interview.
Design of the intervention studies
Two intervention studies were conducted. In the first intervention study, 127 job seekers responded to a fictitious vacancy, sending their CV and completing a structured form (the intervention). 112 HR professionals assessed the job seekers on their job suitability. They also answered a number of questions about their personal views and beliefs about diversity and about their similarity to the applicants. The use of a standardized form instead of the traditional CV appeared to reduce the influence of coincidental assessment differences (noise) and of differences between individual HR professionals in the perceived equality with applicants (bias), because the assessors had to work in a more structured way.165 HR professionals participated in the second intervention study, including the 112 professionals mentioned before. Using fictitious job interviews - that is, videos with fictitious applicants who were equally suitable for the job but differed in their ethno-cultural profile - the results showed that the influence of random assessment differences (noise) and of differences between individual HR professionals’ motivations to be unbiased (bias) disappeared when structuring the interview.
