If your data set was compiled by a single person, well, easy enough.

If your data set was compiled by thousands of mechanical turk workers, well, you got a lot of people to blame a little bit. As it goes, "everybody is a little racist sometimes..." and apparently that shows on a big enough data set.

amazing, how when even more people are involved with selecting and tagging the input, it becomes even less likely any one person was to blame.
