Which cognitive biases were evident in ValuJet Airlines's collapse?

5 bias patterns are documented in this case, led by Status Quo Bias. The full set: Status Quo Bias, Authority Bias, Cognitive Misering, Hindsight Bias, Loss Aversion. Each is mapped to Decision Intel's 22-bias R²F taxonomy with stable IDs and academic citations.

Did these cognitive biases cause ValuJet Airlines'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. Status Quo Bias 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.

Critical · 5 biases detected, 2 toxic combinations

ValuJet Flight 592 crashed into the Everglades, killing 110 people, when improperly packaged oxygen generators ignited in the cargo hold. The FAA had documented serious safety concerns about ValuJet's rapid expansion but delayed grounding the airline due to political pressure.

Decision context

Whether the FAA should have grounded ValuJet based on its own inspectors' findings of systemic safety deficiencies before the crash, and whether outsourced maintenance oversight was adequate.

■ Failure■ Partial■ Success

Lessons learned

Status quo bias in FAA oversight: regulatory action against airlines is culturally difficult because the FAA sees its role as promoting aviation
Outsourced maintenance to lowest-cost providers without adequate oversight created systematic safety gaps
Hindsight: FAA inspectors had documented the exact risks months before the crash, but the system had no mechanism to force action
