Google Photos was making the same mistakes. Why? The answer is right back in those tech-company offices we encountered in Chapter 2. If you recall, Google reported that just 1 percent of technical staff was black in 2016. If the team that made this product looked like Google as a whole, it would have been made up almost entirely of white and Asian men. Would they have noticed if, like COMPAS, their failure rates disproportionately affected black people?
