Relative Objectivity Bias

The comfortable middle-ground fallacy that truth is simply whatever emerges from averaging all available perspectives. It's objectivity via committee. The Relativist assumes that if you gather enough different viewpoints and split the difference, you'll naturally arrive at something approximating truth. This ignores that some perspectives are more informed than others, some are actively malicious, and the average of many wrongs rarely makes a right. It's the bias of people who think both sides in every debate are equally valid and the truth must live peacefully somewhere in the no-man's-land between them.
