Key findings: -No-Have improves ethical reasoning by 19pp (p&amp;lt;0.001) and epistemic calibration by 7.4pp across all models -E-Prime improves Gemini&amp;#x27;s ethical reasoning by 42pp but collapses GPT-4o-mini&amp;#x27;s epistemic calibration by 27pp -Cross-model correlations reach r=-0.75 — the same…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2603.27626/"&gt;Paper and discussion history&lt;/a&gt;.
