Which cognitive biases were evident in Groupon's failure?

5 bias patterns are documented in this case, led by Recency Bias. The full set: Overconfidence Bias, Anchoring Bias, Recency Bias, Bandwagon Effect, Hindsight Bias. Each is mapped to Decision Intel's 22-bias R²F taxonomy with stable IDs and academic citations.

Did these cognitive biases cause Groupon's failure?

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. Recency 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

Groupon rejected Google's $6B acquisition offer and IPO'd at a $13B valuation. The daily deals model proved unsustainable as merchants saw no repeat customers, and Groupon's accounting metrics were questioned by the SEC. The company lost 90%+ of its market cap.

Decision context

Whether to accept Google's $6B acquisition offer or proceed with an IPO at a higher valuation, betting that the daily deals model had sustainable economics.

Lessons learned

Recency bias: explosive 2010-2011 growth was extrapolated as the new normal rather than a novelty-driven spike
Anchoring to the $6B Google offer as a floor rather than treating it as a genuine exit opportunity
Daily deals failed because they attracted deal-seekers who never became regular customers — the business model had negative retention
