Realism, yes, yes.
It could clearly be a little more robust, but I know not everyone enjoys filling out 100+ questions on these kinds of things to see their method. What I would really like to see on this one is cultural bias (like pretty much every one ever). I would take any results from it with a grain of salt as any results based on pictures is going to be based on an average interpretations of a picture (or one persons interpretation lololol).
Like I said though, interesting presentation.
