Overview
The purpose of this research was to evidence the higher susceptibility of potential appraisals to age and gender bias in comparison to performance appraisals.
​
To test our hypothesis empirically, we analysed two large archival datasets, one from a German chemical multinational and one from a Belgian finance company, using regression analyses and structural equation modelling. We also conducted a vignette experiment to replicate our findings, while keeping all other factors constant.
​
Our results
​
Showed that potential appraisals were biased against older employees who received systematically lower ratings than younger employees, and that this negative age effect was stronger for potential than for performance appraisals. Moreover, age also affected pay raises and promotions in the next year via potential ratings. Our experiment showed that the different scores of older and younger employees could not be attributed to differences in competence level, meaning that they reflected actual bias. For gender, effects were largely absent.
In conclusion
Our results suggest that potential appraisals entail a serious risk for age discrimination in organisations, because they structurally limit the career opportunities of older employees, creating a so-called ‘silver ceiling’.
