From: A meta-analysis of the persuasive power of large language models
Forest plot of effect sizes (Hedges’ g) comparing the persuasive effects of LLMs vs humans. Each line represents one effect size estimate with its \(95\%\) confidence interval. The orange shaded area indicates the \(95\%\) confidence interval of the pooled effect. Study weights are shown on the right. Positive values indicate that LLMs were more persuasive than humans, whereas negative values indicate that humans were more persuasive. The overall effect size was very small and non-significant (\(g = 0.02\), \(p =.530\), \(95\%\) CI [\(-0.048\), 0.093]). Substantial heterogeneity was observed (\(I^2 = 75.97\%\)).
