Norm Bias

The cognitive tendency to unconsciously favor, trust, and perceive as correct those ideas, behaviors, and people that align with the dominant social norms of one's group or culture. It creates a mental shortcut where "normal = good/safe/true." This bias makes it difficult to even see alternative ways of thinking as legitimate, framing them automatically as threats, errors, or absurdities before they are evaluated on their own merits.

Example: In a corporate culture that values aggressive confidence, a quiet, reflective contributor's ideas are consistently overlooked in meetings due to Norm Bias. Their style doesn't match the "norm" of how good ideas are presented, so the ideas themselves are filtered out as weak, regardless of their actual quality.
