That personality test is powered by DatStat, and it is more powerful than the one used at eHarmony.
It has over 110 questions and it seems to be a normative personality test in English for the United States.
The Results are 5 written feedbacks, as if it was an adapted Big 5 model, but it does not show any numerical scales.
The 16PF5 normative personality test is more powerful and better than that Personality Quiz powered by DatStat.
I suspect eHarmony is going to launch a new online dating site based solely on strict personality similarity, and they are testing that Personality Quiz.
