Opinion vs Evidence
A Practical Playbook for Data-Driven Talent Reviews
About whitepaper

This playbook explains how HR managers and leaders can run data-driven talent reviews that support promotion, succession planning, and leadership development decisions. Using behavioral science and evidence-based assessment principles, it shows how to move beyond opinion, performance ratings, and subjective labels by focusing on the behavioral capabilities that best predict future performance, adaptability, and growth.

What you’ll learn:

  • Why traditional talent reviews struggle to predict future capability
  • The limitations of performance ratings, engagement scores, and gut feel
  • Which behavioral signals are most useful for forward-looking talent decisions
  • How to redesign talent reviews around evidence, not labels
  • A practical, decision-first workflow for more defensible talent reviews
