About TraitLab


I'm Greg, creator of TraitLab.

I had my first experience with modern personality tests as a PhD student studying psychometrics. My results created a huge "a-ha!" moment of personal insight and major turning point in my life.

As I reflected on the results, I noticed how they related to several aspects of my life that weren't working out as I'd expected. And I realized that some of my perceived weaknesses were actually strengths.

I wanted even more insights about my personality, but the world of personality testing was overwhelming and confusing. There were so many competing tests, theories, and "experts," and I couldn't decide which was best.

So, I relied on my training and did my own research.

I spent hundreds of hours combing through published scientific articles. I searched for the most reliable, research-backed assessments. I studied how these assessments connected to important areas of life, like career, relationships, health, and well-being. And I combined them into one powerful platform: TraitLab.

I've learned that I'm not alone. Since I made it publicly available, TraitLab has helped thousands of people learn more about their personalities.

What is TraitLab?

TraitLab provides research-based assessments of personality, strengths, interests, and other important dimensions of individuality. TraitLab was founded in 2020 and is based in Ohio, U.S.A. One of TraitLab's primary goals is to improve awareness of personality science.

Who created TraitLab?

TraitLab was created by Greg Park — that's me! 👋

I earned a PhD in psychology (focused on quantitative methods) from Vanderbilt University, worked 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.
