I think that helps create an ideal environment for a fun psych study. Both choices are seemingly identical, so why pick one over the other? What makes people decide to pick the top or bottom one? More people are choosing the top one than the bottom one, showing a slight bias in preference. I chose the bottom one because I like to root for the underdog, as I figured prior to voting that the top choice would out number the bottom choice 2-1. Seems I was a little off, but the point remains that people are showing a preference for the top selection, regardless of the fact that both are identical.
You can also choose both and this hardly has the makings of a psychological experiment.
