The evaluation of personnel selection methods by HR practitioners: The effect of reference and its interaction with information about validity
The study was an online administered between-subjects experiment. The online survey was completed by 173 Czech HR professionals who were recruited through Linkedin. Dependent variables: Participants assessed the suitability and quality of 6 personnel selection methods. Treatments: One of four randomly selected versions of the survey appeared. These versions differed in the presence or absence of a positive reference (to companies that use the method) and the presence or absence of information on the predictive validity of the selection methods. Control variables: The participants were asked whether they were familiar with each of the methods before completing the survey.
