A lot of comments are voicing opinions about politeness, but I&#x27;d like to focus on the study. In particular, I&#x27;d like to disagree with the conclusion. If you look at their stats and box plots, its a mess. They should run the Wilson test on all their data, not split it up by project. Also, the effect size is miniscule. In a couple of cases, it&#x27;s negative, though p &gt; 0.05 for those.<p>Before reading this study, I thought politeness helped fix issues faster. Now, I&#x27;m of the opinion that it has little or no effect. Of course, polite discourse is more pleasant, so I&#x27;ll continue to be nice when communicating.
