The Big Five Project

Take the big five personality test here!

Over the years, I’ve worked on a number of collaborations with researchers at universities, creating websites that give personality test takers information about themselves while at the same time gathering data for researchers to learn more about human personality.

Over 15 million people have learned about their personality from my work. The original site,, will slowly be transitioned to this domain, using a name that better reflects the nature of these collaborations.

In the mean time, I invite you to visit the original site to learn more about my personality research work.
