As someone who is more of a lefty, I liked it. But as someone who works in a UX agency, it feels like the statements are written with a left-leaning bias to them, with a few others thrown in for "balance". Where the statements researched individually, and as a whole?
Also, it would be good to see the site state upfront that it is US-based. As someone who is in the UK :)
I love it. It was really fun to take, and I learned a lot about myself. I love the progress bar, and the actions I can take after analyzing the results. I wonder what the implications of excluding"Strongly agree / Strongly disagree" are. It might reduce the % of people testing for strong personalities.
