摘要
En 中文
How many interviewers per job applicant are necessary for a company to achieve the highest hit rate? Are two better than one? Condorcet's Jury Theorem and the wisdom of the crowd suggest that more is better. Under quite general conditions this study shows, surprisingly, that two interviewers are on average not superior to the best interviewer. Adding further interviewers will also not increase the expected collective hit rate when interviewers are homogeneous (i.e., their hits are nested), only doing so when interviewers are heterogeneous ( i.e., their hits are not nested). The current study shows how these results depend on the number of interviewers, their expertise, and the chance of free riding, and specify the conditions when less is more. This analysis suggests that the best policy is to invest resources into improving the quality of the best interviewer rather than distribute these to improve the quality of many interviewers.
