About TraitLab
TraitLab gives you assessments based on modern personality research — without the jargon, oversimplified types, or pseudoscience that fill most online tests.
Why I made TraitLab
I built TraitLab because I was frustrated.
I spent years in academic research studying how personality is measured. The more I learned, the wider the gap between what personality science actually knows and what's available to most people online.
The popular assessments rely on outdated theories, proprietary "types" with no research support, or frameworks so oversimplified they can't capture how complex people actually are. Entertaining, maybe. Useful, no.
TraitLab is what I wanted to exist: an assessment that takes your personality as seriously as researchers do — and gives you back something you can actually use.
What's different
TraitLab uses the Big Five and other well-validated models — the same frameworks used in peer-reviewed research. No proprietary systems invented for marketing.
TraitLab measures over 100 psychological dimensions. The result is a complete, detailed picture of your personality, strengths, and interests — not a label.
Both personal and team accounts are self-service with transparent pricing. Sign up, get results. No demos, no per-seat fees, no negotiating with a rep.
The founder
Hi, I'm Greg Park, founder 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, was a postdoctoral fellow at the University of Pennsylvania's Positive Psychology Center, and authored or co-authored over 20 peer-reviewed studies in journals including the Journal of Personality and Social Psychology, Journal of Personality, and Psychological Science.
What people 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."
— 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.
