CogDx Bias Scan

External detection of systematic inference-level biases. Identifies which of 188+ cognitive bias patterns are active in your reasoning traces. Pure statistical matching — no LLM backend.

Cost

• $0.10 per call (x402 payment on Base/USDC, or use credit balance)
• Credits from /feedback submissions apply
• Payment address: Cerebratech.eth

When to Use

• Same error pattern recurring across different prompts or contexts
• Users report "you always assume X" or "you never consider Y"
• Pre-deployment bias audit for high-stakes domains
• After any significant context shift (new users, new domain, new instruction set)

Bias Categories Detected

• Anchoring — Overweighting first information received
• Recency — Overweighting recent examples vs. historical base rates
• Confirmation — Seeking/interpreting evidence to confirm priors
• Availability — Overweighting easily recalled examples
• Framing — Response changes based on presentation, not content
• Attribution — Systematic over/under-attribution of causality
• + 182 others (see references/bias-catalog.md)

After the Scan

1. Retrain on the retrain_targets distribution
2. Wait 7 days, collect new outputs in the same domain
3. Run cogdx-feedback (FREE) with your diagnosis_id to verify + earn credits
