Personality tests in the workplace: pros and cons

Team workshops, leadership programs and hiring processes often include personality tests. Some uses are helpful, some questionable, and the difference depends on purpose, validity and consent.

The short answer

Personality tests at work can help people understand their working styles and communicate better, especially in voluntary development settings. The risks arise when tests are used for hiring, promotion or performance decisions without evidence that they are valid for those purposes, or when results are shared without consent. The Enneagram, in particular, isn't validated for employment decisions.

Pros and cons by use

Voluntary self-developmentSelf-awareness, reflectionOveridentifying with a label
Team workshopsShared language for differencesStereotyping, pressure to share
CoachingStructured conversationsRelying on the tool over the person
HiringNone validated for the EnneagramUnfairness, legal and ethical concerns
Promotion or evaluationNot appropriate for typologiesBias, loss of trust

What's actually going on

Validity depends on purpose. A tool can be reasonable for starting a conversation and completely unsuitable for deciding who gets a job. Professional assessment guidance stresses matching tools to purposes supported by evidence and considering fairness. Workplace tests also raise privacy questions: personality information can feel sensitive, and people may worry about how it will be used.

Questions to ask about any workplace test

QuestionWhy it matters
What is the purpose?Determines whether the tool is appropriate
Is participation voluntary?Protects autonomy and trust
Who sees the results?Protects privacy
Is there evidence for this use?Ensures fairness and accuracy
Will results affect decisions about me?Identifies higher-risk uses

An example of the line being crossed

A team workshop uses the Enneagram to discuss working styles, which most people find useful. Months later, a manager suggests promoting someone because their type seems "a natural leader." At that point, a reflective tool has become an evaluation tool it was never designed to be.

Using tests well at work

  • Keep participation voluntary.
  • Let individuals control whether they share results.
  • Use results to open discussions, not end them.
  • Never use typologies in hiring, promotion or pay decisions.
