Subclaims¶

q2 i? Collective intelligence as measured by score improvement emerged for the large group G1 on question 1 but the improvements were not significant in the smaller groups G2 and G3. → Tatiana Íñiguez-Berrozpe 2025

q2 · i? · causal · r1

Mixed model repeated-measures analysis of mean answer scores across the seven phases in the Collective Learning experiment, comparing G1 (n = 123), G2 (n = 18) and G3 (n = 20). The authors state "we observed a significant effect in group G1 from phase 5 onward"; no effect size is printed.

"For question 1, we observed a significant effect in group G1 from phase 5 onward (phase 4–5; p < 0.001), whereas such an effect was not significant in the smaller groups G2 and G3."

Discussion¶

Related Claims¶

• Mean answer scores in the large group rose continually across the interaction phases, especially from phase 4 onward, but stagnated on question 3 — possibly the same claim (merge candidate)
• The small groups did not improve on questions 1 and 4, G2 declined on questions 2 and 3, and G3 improved only on question 2 — possibly the same claim (merge candidate)
• Omnibus tests found significant group, phase and group-by-phase effects on questions 1 and 2, and predominantly group effects on questions 3 and 4
