The ethical and practical error of believing that the will of the numerical majority (50%+
1) should always prevail, not just in elections, but in determining what is fair, true, or just in a
society. It is the operational engine of "tyranny of the majority," where minority rights, interests, and truths are sacrificed on the altar of
popular sentiment. This bias confuses quantity with quality and power with justice.
Example: A town votes to
ban the construction of a mosque because the majority are Christian and uncomfortable with it. Defenders say, "It's the will of the
people." This Majoritarian Bias uses the majority's cultural preference to justify religious discrimination, treating
democracy as a weapon rather than a protection.
