Dear User,

Twenty years ago, on the back of Richard Peterson's Stanford neuroeconomics post-doc, we posted our first free financial psychology tests online. Over the ensuing years we added and refined 12 tests. Around 40,000 investors and traders took the tests and were given profiles. We appreciated the interest and we sincerely hope they have proven beneficial and worthwhile for our users.

The technology to support such tests has evolved, and rather than update them, we’ve decided to take them down and discontinue maintenance. Our business now focuses primarily on natural language processing, media's effects on market prices, and quantitative analytics. Feel free to see more about our primary business on

Best wishes in your trading (and life) journey,

Richard Peterson
