How is sensitive data protected?

All documents are encrypted with AES-256-GCM at rest and TLS 1.2+ in transit. A GDPR anonymization layer removes PII before any AI processing. Hosted on Vercel + Supabase (both SOC 2 Type II); Decision Intel’s own product-level audit is targeted for Q4 2026.

How long does integration take?

Less than 30 minutes. Upload documents directly, connect via OAuth for Slack, or use our REST API for bulk processing.

How does outcome tracking work?

Outcomes are detected automatically from follow-up documents, Slack messages, and web intelligence. You confirm with one click. Each reported outcome makes your future analyses more accurate.

How is Decision Intel different from ChatGPT or a general AI assistant?

ChatGPT gives one opinion from one model: ungoverned, untraceable, unaudited. Decision Intel is the reasoning audit platform. Most tools audit your data; we audit your reasoning — and catch the fatal blind spots in strategic memos before the committee does. It measures the noise in your reasoning the same way Kahneman did in the insurance underwriter study, simulates an AI boardroom of CEO, CFO, and board personas, runs what-if interventions against a 143-case public reference library, and compounds every confirmed outcome back into a calibrated Decision Quality Index your audit committee can defend. Not a chatbot; a reasoning audit, checkable from memo to outcome.

Which cognitive biases caused Massey Energy's collapse?

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

What is Decision Intel's reasoning audit?

Decision Intel runs a 12-node Recognition-Rigor Framework (R²F) pipeline 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.

Massey Energy

Massey Energy Upper Big Branch Mine Disaster

Estimated impact: 29 deaths; $210M settlement; CEO imprisoned

F14

Decision Quality Index (simulated)

Critical · 5 biases detected, 2 toxic combinations

An explosion at the Upper Big Branch coal mine in West Virginia killed 29 miners. Massey Energy had accumulated 515 safety violations in the prior year. CEO Don Blankenship created a culture where production targets overrode safety protocols, and managers who raised safety concerns were transferred or fired.

Decision context

Whether to address hundreds of documented safety violations and ventilation problems at Upper Big Branch or continue prioritizing coal production volume.
