Which cognitive biases were evident in MoviePass / Helios & Matheson's collapse?

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

Did these cognitive biases cause MoviePass / Helios & Matheson'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. Planning 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.

MoviePass Subscription Collapse

Estimated impact: $300M+ investor losses

F16

Decision Quality Index (simulated)

Critical · 4 biases detected, 2 toxic combinations

MoviePass offered unlimited movie tickets for $9.95/month when single tickets cost $12+, assuming scale would force theaters to share revenue. Burned through $40M/month with no path to profitability.

Decision context

CEO Mitch Lowe and parent company HMNY leadership believed subscriber volume would create negotiating leverage with AMC and Regal. They rejected financial models showing unsustainable burn rate, citing "disruption" narratives.

■ Failure■ Partial■ Success

Lessons learned

The subscription was priced below the per-user cost of the underlying tickets, so every new subscriber increased the loss; growth was read as validation while it was mechanically the burn rate, and the model had no lever to invert once scaled.
Platform negotiating leverage requires genuine alternatives for counterparties
Disruption narratives cannot override basic financial math
