However, some news sources make some effort to reduce bias and otherwise function within an ethos that bias is something that reporters should try to avoid unless there's good reason for apparent bias. (For example, stories about smoking causing lung cancer, or about plate tectonics, don't require "balance" and contribution from opposing viewpoints because the opposition viewpoints are a tiny fringe without support.)

Other news sources, like Fox, don't even bother.
