Personality assessments are everywhere in today’s workplace: used for hiring, leadership development, team effectiveness, and coaching. But not all assessments are created equal, and choosing the wrong one can lead to oversimplification, misinterpretation, or even unintended harm.
Before adopting a personality assessment, leaders should pause and ask these five critical questions:
-
What decisions will this assessment inform?
Is it being used for development, selection, team insight, or coaching? An assessment designed for self-reflection may not be appropriate for hiring or promotion decisions. Clarity of purpose should come first.
-
Is it grounded in well-established research?
Look beyond marketing claims. Is the tool based on a widely accepted psychological model? Has it been validated through peer-reviewed research and workplace studies? Scientific rigor matters, especially when real people and real decisions are involved.
-
Does it measure stable traits or temporary states?
Effective personality assessments focus on relatively stable traits rather than moods, preferences, or situational behaviors. This distinction is essential if you want insights that are reliable over time.
-
How will the results be interpreted and applied?
An assessment is only as useful as the context provided around it. Who will debrief the results? What training do they have? Without skilled interpretation, even good data can be misunderstood or misused.
-
Does it support development, or justlabeling?
The goal should never be to box people in. Strong assessments help leaders understand patterns, strengths, and potential derailers while reinforcing growth, adaptability, and responsibility.
Bottom line: Personality data can be a powerful tool for leadership and organizational development, but only when used thoughtfully, ethically, and with the right expertise.
For leaders, coaches, and HR professionals who want to use personality data well, working with research-backed tools and practitioners trained to interpret them makes all the difference.
