middle_ground
The middle ground fallacy assumes that the truth must lie between two extreme positions, or that a compromise is always the most reasonable solution. While moderation and compromise are often pragmatically wise, they are not always logically correct. When one side is right and the other wrong, splitting the difference yields an incorrect answer. Truth is not determined by averaging competing claims.
"Scientists say the Earth is 4.5 billion years old. Young Earth creationists say it's 6,000 years old. The truth probably lies somewhere in between -- maybe a few million years."
During a vaccine safety debate, a talk-show host concludes: 'Medical experts say vaccines are safe and effective, but some guests tonight say they're dangerous. I think the sensible position is that vaccines are probably somewhat risky — the truth is always in the middle.'
A manager mediating a workplace dispute says: 'One employee says the project deadline is completely unrealistic, and another says it's perfectly fine. So let's just cut the timeline in half — that's the fair compromise.' (Even though the original deadline may have been genuinely impossible.)
Position(A) AND Position(B) -> True(Midpoint(A, B))

Truth is not determined by averaging competing claims.
Compromise feels fair and balanced, and people associate moderation with wisdom and extremism with error. The middle position appears reasonable by default, especially to those who want to avoid conflict.
Point out that truth is not determined by averaging positions. If one side has strong evidence and the other does not, the middle is still wrong. Evaluate each position on evidence, not on its position relative to the other.
Common in media 'both-sides' coverage, political centrism for its own sake, dispute mediation where splitting the difference is default, and negotiations where fairness is confused with accuracy.
