You know your a Nonconformist when.... [insert Jeff Foxworthy type joke]
Apparently later in the game, when you need to build a Flagship, you have to prove to the workers building it that your not just another sheep. So it's thought that voting opposite the majority will get you the reputation you need to get your Flagship built.
Now, if everyone starts being a Nonconformist, they'll end up being Conformists and no one will get their Flagships built. But we'll get our Unity Money... maybe.
