About this episode

Dr. Grajdek discusses the psychology behind hiring mistakes and offers strategies to improve the hiring process.

Hiring Mistakes Psychology: Why We Choose the Wrong Person (and How to Stop) Hiring errors are often predictable outcomes of bias—halo effect, similarity bias, pedigree bias, and the common trap of mistaking confidence for competence. In this episode, Dr. Grajdek explains why “vibe hiring” feels compelling but produces uneven results. Furthermore, she discusses a science-based process: structured interviews, behavior-anchored scorecards, work samples tied to real job tasks, and independent scoring before group discussion to reduce groupthink. Dr. Grajdek also covers reference checks that focus on patterns rather than adjectives and the post-hire validation plan (30/60/90 expectations) that catches issues early while supporting success. The takeaway: fairness and accuracy improve together when the process is designed well. Tune in to learn more.
