I have a theory that unicyclists are Sensation Seekers, due to the nature of our minority sport.
I also thing that those of us who hate the random non-unicyclists comments are Introverts and those that don’t care are Extroverts.
If anyone would like to try out my theory, you can take Zuckerman’s Sensation Seeking scale at http://www.bbc.co.uk/science/humanbody/mind/surveys/sensation/index.shtml
and a personality test at http://www.bbc.co.uk/science/humanbody/mind/surveys/whatamilike/index.shtml
to find out about the intorversion/extraversion thing.
If you do have a go, I would love it if you posted your results on this thread.
Edit: My overall Sensation seeking score is 26/40. I scored high in Thrill & Adventure Seeking, Experience Seeking and Disinhibition and low on boredom suseptability. I also come out as an introvert.
