Finally, a personality test that takes you seriously.

Why I made TraitLab

I built TraitLab because I was frustrated.

For years, I worked as an academic researcher studying personality measurement. The more I learned, the wider the gap seemed between what personality science actually knows and what's available to most people.

The most popular assessments often rely on outdated theories, proprietary "types" with no research support, or frameworks so oversimplified they can't capture how complex people actually are. They can be entertaining, but they're not useful.

I wanted an assessment that was both rigorous and useful — one that views your personality with the same nuance and rigor that researchers do.

What makes TraitLab different?

TraitLab combines modern psychological research with intuitive tools to personalized, straightforward results. Here’s what sets TraitLab apart:

• Grounded in established science: TraitLab uses the Big Five and other well-validated models — the same frameworks used in peer-reviewed research. No proprietary systems invented for marketing.
• Rigorous and comprehensive: Our assessments are exacting and thorough, because TraitLab measures over 100 psychological dimensions. The result is a complete, detailed picture of your personality, strengths, and interests.
• No consultants, no sales calls: Need assessments for your business or team? TraitLab Pro is completely self-service with simple, transparent pricing. Sign up, invite your team, and get results without waiting on a demo or negotiating with a rep.

What people say about TraitLab

"What I love most about TraitLab is that it understands that personality is complex. I have taken several other personality tests, but I felt that they were very surface level, and I didn’t fit any of the results I received. TraitLab is so comprehensive that I feel like I can really trust the results — it gave me what I was looking for, which is truth and accuracy. I felt like the test really understood who I was. And I really enjoyed looking at the careers too — I definitely wish I had TraitLab as a resource when I was in college." — G. N.

"Compared to every other test I've taken, I'd say that TraitLab is my favorite one. Mostly for its comprehensiveness, its ease of use, the fact that it's really well thought-out ... I feel like it comes from a genuine, research-oriented perspective." — Luke H.

"I love the different personality classifications TraitLab provides, from scientific models to more philosophical ones or those frameworks most popular in industry. I also love the level of detail on the Big Five results, the well-explained descriptions, and the intuitive data visualisations. Overall, it's the most comprehensive, accurate, and data-driven online tool I've ever seen." — M. T.
