The Story Behind TraitLab

I started TraitLab to bridge the gap between modern personality science and everyday tools that anyone can use. After years of academic research in psychology, I realized there was a growing demand for assessments that were not only scientifically rigorous but also accessible and easy to use.

The idea behind TraitLab is simple: make powerful personality insights available to everyone — whether you’re navigating your career, improving your relationships, or leading a team. Founded by a Ph.D. in psychology, TraitLab combines expertise with practical tools for personal and professional growth.

Why Customers Love TraitLab

What do the people who use TraitLab say?

"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.

Hi, I'm Greg Park, creator of TraitLab. 👋

As you can see from my own personality profile, I'm a deeply curious researcher who loves investigating complex problems.

Before starting TraitLab, I earned a Ph.D. in quantitative psychology from Vanderbilt University, conducted research as a postdoctoral fellow at the University of Pennsylvania's Positive Psychology Center, and authored or co-authored over 20 peer-reviewed studies in scientific journals such as the Journal of Personality and Social Psychology, Journal of Personality, and Psychological Science.
