> Knowing where to draw the line is hard Not only that. If the line is way too far on one side or the other, everyone agrees that it is, and then it's shifted. If the line is approximately at the optimum, some agree it is, and those that disagree are about half convinced that it's too far this way, half it's too far that way. So, having maximum disagreement is in itself arguably an indicator that you got it approximately right.
