Julian Matthews @quining.bsky.social · 30/09/2025The result: negligible effect ⚡ Metacognitive efficiency is robust to report order—it need not constrain study design and secondary analysis...

Julian Matthews @quining.bsky.social · 30/09/2025We tested this directly, 2 experiments (perception & memory, n=175) controlling for ⏱️ timing and ✋ motor preparation. 7 registered hypotheses and 3 different measures unpacked order bias from all angles. 110
