If everyone is thinking alike then somebody isn't thinking.

The line is a pointed warning against groupthink: unanimous agreement can signal conformity, intimidation, or unexamined assumptions rather than genuine analysis. Attributing it to Patton fits his reputation for blunt leadership and insistence on initiative, but the sentiment is broadly applicable beyond military settings—healthy organizations need dissent, independent judgment, and the courage to challenge prevailing views. The quote also implies a practical epistemic claim: complex problems rarely yield a single obvious answer, so uniformity should prompt leaders to ask what perspectives are missing and whether people feel safe to disagree.
