Which cognitive biases were evident in U.S. Army / Boeing / Sikorsky's collapse?

5 bias patterns are documented in this case, led by Sunk Cost Fallacy. The full set: Sunk Cost Fallacy, Planning Fallacy, Status Quo Bias, Overconfidence Bias, Anchoring Bias. Each is mapped to Decision Intel's 22-bias R²F taxonomy with stable IDs and academic citations.

Did these cognitive biases cause U.S. Army / Boeing / Sikorsky's collapse?

Decision Intel identifies reasoning-risk indicators correlated with poor outcomes — it does not claim to establish causation. That honesty is the procurement weapon: a CSO can defend a score that names the risk indicators a committee should pressure-test, not one that pretends to prove the cause. Sunk Cost Fallacy and the other documented patterns were detectable in the reasoning before the outcome was known; whether they caused it is a question no audit can settle — too many other factors (market, timing, execution) are in play. A reasoning audit names the risk indicators a committee should pressure-test, not a verdict it should accept.

What is Decision Intel's reasoning audit?

Decision Intel runs a Recognition-Rigor Framework (R²F) audit on strategic memos, detecting cognitive biases from a 22-bias canonical taxonomy and producing a Decision Quality Index (DQI) score. The audit produces a hashed, tamper-evident Decision Provenance Record (DPR) suitable for audit-committee review.

Decision Quality Index (simulated)

Critical · 5 biases detected, 2 toxic combinations

After 22 years of development and $6.9B spent, the U.S. Army cancelled the RAH-66 Comanche stealth reconnaissance helicopter without producing a single operational aircraft. Requirements changed repeatedly, and the program survived through continuous congressional support despite failing to deliver.

Decision context

Whether to continue funding a program that had been in development for two decades, consumed $6.9B, and still had no production-ready aircraft.

Lessons learned

Sunk cost fallacy in defense procurement: each year's investment made cancellation seem more wasteful than continuation
Requirements creep over 22 years meant the original mission need evolved while the program tried to hit a moving target
Status quo bias: the program survived annual budget reviews because cancelling it required active political courage while continuing it was the default
