The Presenter's Paradox: More Is Not Always Better
研究发现，在沟通中增加低价值信息会降低整体效果，因为接收者倾向于平均评价而非累加。对经管学者而言，投稿时添加过多控制变量、分析或图表可能反而削弱论文价值。
The presenter's paradox is a phenomenon wherein adding low-value information alongside high-value information reduces the overall effectiveness of communication. This is because receivers tend to evaluate messages using an averaging, rather than additive, approach. In the context of journal submissions, the presenter's paradox arises when authors undermine their papers’ value by adding extra components that fail to maintain the high standard established in the core of the paper. These additions might take the form of excessive control variables, supplementary analyses, hypotheses, words, tables, figures, or citations. We argue that authors should construct journal submissions with the presenter's paradox in mind––because in many cases, less is more.
