I was considering perception versus projection, when I had an idea; why not test it?
The game is simple: mention those who know you best, and get them to take a test as they imagine you would answer. I Have gathered a few tests under the spoiler, but feel free to use whichever tests you please.
EDIT: A simpler more personal alternative is to pick a few words that you think describe you. Place them under a spoiler; then compare them with those you mention.
