Majority Bias

A cognitive and social tendency to instinctively side with, trust, and defer to the perceived majority opinion within a group, regardless of the opinion's factual or ethical merits. It's the mental shortcut that "if most people believe it, it must be true/safe/right." This bias underpins conformity, groupthink, and the chilling effect where dissenting voices are silenced not by law, but by the sheer social weight of assumed consensus.

Example: In a meeting, even members who privately doubt a plan will remain silent and eventually agree once they perceive (rightly or wrongly) that "most people" are for it. This Majority Bias creates false unanimity and leads to disastrous decisions because the actual distribution of critical thought is hidden by the fear of being the outlier.

Majority Neutrality Bias

The belief that the most common or popular position on an issue is automatically the most neutral one—that consensus equals objectivity. The Majority Neutralist assumes that if most people believe something, that belief must be free of bias, because bias is deviation from the norm. This flips the actual relationship: majorities have the most powerful biases, the ones that get to dress up as "common sense" precisely because they're invisible to those who hold them. The majority view isn't neutral—it's just the bias you don't have to defend.

"Most people in this country agree with me, so I'm obviously not biased—I'm just normal." That's Majority Neutrality Bias: mistaking the water you're swimming in for the absence of water.
