Definition: Sunk Cost Defense is the reflex to keep funding legacy training or tooling because “we’ve already paid,” even when execution data shows drift persists and impact is illusory. The mindset protects optics (budgets, certificates) instead of outcomes (behavioral consistency).
Why it Matters: This defense freezes change, diverts budget from reinforcement, and normalizes inconsistency as “good enough.” Over time, drift compounds quietly while leadership convinces itself progress is happening.
Leadership Execution System Fix: Treat Sunk Cost Defense as a risk signal. Name it, surface behavior-level evidence, and re-allocate spend toward reinforcement mechanisms that produce visible, repeatable alignment—measured by consistency, not completions.
Common Mistake: Saying, “We’ve already invested too much to stop now.”

Sample Usage: “Leadership resisted change, saying we’d already spent millions. The Sunk Cost Defense ended once behavior evidence showed zero alignment gains.”
