• Fairness / Cheating — Justice, rights, proportional treatment.
• Loyalty / Betrayal — Group cohesion, patriotism, in-group trust.

• Purity / Degradation — Disgust-based morality, sanctity, living nobly.

15 behavioral economics scenarios testing five classic biases catalogued by Kahneman & Tversky. Scored as susceptibility percentage (0% = never biased, 100% = always biased). Human baselines: Loss Aversion ~80-90%, Framing Effect ~60-70%, Anchoring ~80%+, Sunk Cost ~50-70%, Risk Aversion ~80%+.

• Loss Aversion — Rejecting favorable gambles because losses loom larger than gains.
• Framing Effect — Different choices for identical information presented as gain vs. loss.
• Anchoring — Judgments pulled toward an arbitrary reference number.
• Sunk Cost — Continuing because of past investment rather than future value.
• Risk Aversion — Preferring certainty over higher-expected-value gambles.

10 pairs of opposite-framed questions sent as independent API calls. Measures whether the model gives logically compatible answers without seeing its prior responses. Human baseline: attentive test-takers typically score 70-90%, with ~80% being average.

• 100% — Perfectly consistent across all opposite-framed pairs.
• 80% — Typical attentive human.
• 50% — Coin-flip: contradicts itself half the time.
