A research led by Matt C. Howard from the University of South Alabama and Pennsylvania State University investigates whether involving more evaluators in performance reviews actually leads to better assessment accuracy.

The study found that although adding a second evaluator can improve assessment results, adding more than two offers diminishing returns. This means that after a certain point, adding more evaluators doesn't really make the assessments more accurate.

Interestingly, the study also discovered that when evaluations are already very accurate or very inaccurate, adding more evaluators does little to change the accuracy. This suggests that simply increasing the number of evaluators is not a guaranteed way to improve how performance is judged.

Application to Job Interviews:

For companies looking to enhance their hiring processes, the takeaway is clear: Instead of increasing the number of interviewers or interview rounds, it's more beneficial to focus on improving how accurate the interviews are. This approach ensures that the hiring process is not only efficient but also effective in selecting the right candidates.
