Personality Facets: The Missing Layer

created with Envato

Most organisations assess the Big Five personality dimensions.

But the Big Five is a 30,000-foot view. Facets are where prediction happens.

Example: "Conscientiousness" is too broad for precise prediction.

But its facets tell a different story:

→ Achievement-striving predicts sales performance

→ Deliberation predicts quality control roles

→ Order predicts administrative success

→ Self-discipline predicts project management

Same trait, completely different occupational implications.

For practice leaders: Generic personality assessment leaves money on the table.

Facet-level assessment improves prediction by 20-50% in targeted roles. That's the difference between "somewhat useful" and "actually predictive."

The catch: Most personality tools don't report facets, or charge extra for deeper analysis.

Questions for your assessment vendor:

1. Do you report facet scores?

2. What's the validity evidence for facets in my industry?

3. Can we customise which facets matter for different roles?

Big Five is a starting point, not the destination.

Are you using facet-level personality data in selection decisions?
