Which cognitive biases were evident in DePuy Orthopaedics (Johnson & Johnson)'s collapse?

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

Did these cognitive biases cause DePuy Orthopaedics (Johnson & Johnson)'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. Loss Aversion 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

J&J recalled the DePuy ASR metal-on-metal hip implant after failure rates reached 13% within 5 years. Internal documents showed J&J knew about elevated metal ion levels and high revision rates but delayed recall, settling 8,000+ lawsuits for $2.5B.

Decision context

Whether to recall the ASR hip system when internal data showed failure rates significantly above the industry average, or wait for more definitive evidence.

■ Failure■ Partial■ Success

Lessons learned

Loss aversion around a profitable product line delayed a recall that internal data warranted years earlier
Selective perception in interpreting post-market surveillance data allowed J&J to dismiss adverse signals
Metal-on-metal hip implants were adopted industry-wide based on theoretical advantages without adequate long-term human data
