Good point! I didn’t mean to propose it as a solution, but rather as an enumeration or one possibility I’ve considered, and ruled out because it doesn’t work for everyone.
We've had quite a lot of discussions about this internally, and even with humans at the helm with best of intentions about being unbiased, its really easy for a lot of bias to slip in. Even things like the phrasing of questions can introduce bias (i.e. the ol' apocryphal SAT word association problem that had 'regatta:boat').
