Independent meta-analyses on the same topic can sometimes yield seemingly conflicting results. For example, prominent meta-analyses assessing the effects of violent video games on aggressive behavior have reached apparently different conclusions, provoking ongoing debate. We suggest that such conflicts are sometimes partly an artifact of reporting practices for meta-analyses that focus only on the pooled point estimate and its statistical significance. Considering statistics that focus on the distributions of effect sizes and that adequately characterize effect heterogeneity can sometimes indicate reasonable consensus between "warring" meta-analyses. Using novel analyses, we show that this seems to be the case in the video-game literature. Despite seemingly conflicting results for the statistical significance of the pooled estimates in different meta-analyses of video-game studies, all of the meta-analyses do in fact point to the conclusion that, in the vast majority of settings, violent video games do increase aggressive behavior but that these effects are almost always quite small.

在暴力视频游戏的元分析“战争”中找到共同点。

对同一主题进行独立的荟萃分析有时可能会产生看似矛盾的结果。例如，评估暴力视频游戏对攻击行为的影响的著名荟萃分析得出了明显不同的结论，引发了持续的辩论。我们建议，此类冲突有时在某种程度上是针对荟萃分析的报告实践的产物，这些实践仅侧重于汇总点估计及其统计意义。考虑专注于效应大小分布并充分表征效应异质性的统计数据有时可以表明“ warring”荟萃分析之间的合理共识。通过新颖的分析，我们证明了视频游戏文学中的情况似乎如此。
