Inconsistency-Avoidance Tendency
The mind resists change: it conserves prior conclusions, habits, loyalties, and commitments, making them hard to alter even in the face of contrary evidence. This is the engine behind commitment-and-consistency effects. One of Charlie Munger’s 25 causes of human misjudgment.
Examples
- Defending a public stance long after the evidence has turned against it
- Sticking with a strategy because “we’ve always done it this way”
- Escalating commitment to a failing project to stay consistent with past choices
Why It Happens
Holding stable conclusions conserves cognitive energy and protects identity. Once a belief is adopted — especially publicly — reversing it feels like a costly admission of error.
How to Counteract
- Hold beliefs as provisional and update explicitly when evidence shifts
- Avoid premature public commitment before you’ve examined the evidence
- Reward yourself for changing your mind, not just for being right
