Scientific communication poses a challenge: To clearly highlight key conclusions and implications while fully acknowledging the limitations of the evidence. Although these goals are in principle compatible, the goal of conveying complex and variable data may compete with reporting results in a digestible form that fits (increasingly) limited publication formats. As a result, authors' choices may favor clarity over complexity. For example, generic language (e.g., "Introverts and extraverts require different learning environments") may mislead by implying general, timeless conclusions while glossing over exceptions and variability. Using generic language is especially problematic if authors overgeneralize from small or unrepresentative samples (e.g., exclusively Western, middle-class). We present 4 studies examining the use and implications of generic language in psychology research articles. Study 1, a text analysis of 1,149 psychology articles published in 11 journals in 2015 and 2016, examined the use of generics in titles, research highlights, and abstracts. We found that generics were ubiquitously used to convey results (89% of articles included at least 1 generic), despite that most articles made no mention of sample demographics. Generics appeared more frequently in shorter units of the paper (i.e., highlights more than abstracts), and generics were not associated with sample size. Studies 2 to 4 ( = 1,578) found that readers judged results expressed with generic language to be more important and generalizable than findings expressed with nongeneric language. We highlight potential unintended consequences of language choice in scientific communication, as well as what these choices reveal about how scientists think about their data.
既要清晰地突出关键结论和影响,又要充分承认证据的局限性。尽管这些目标在原则上是一致的,但传达复杂多变的数据的目标可能与以易于理解的形式报告结果相竞争,这种结果要适应(日益增长的)有限的出版格式。因此,作者的选择可能更倾向于清晰而非复杂。例如,通用语言(例如,“内向者和外向者需要不同的学习环境”)可能会通过暗示普遍的、永恒的结论来误导读者,而忽略了例外和可变性。如果作者从小样本或代表性不足的样本(例如,仅限于西方、中产阶级)中过度概括,那么使用通用语言尤其成问题。我们提出了 4 项研究,考察了通用语言在心理学研究文章中的使用和影响。研究 1 是对 2015 年和 2016 年在 11 种期刊上发表的 1149 篇心理学文章的文本分析,研究考察了标题、研究重点和摘要中通用语言的使用。我们发现,通用语言被广泛用于传达结果(89%的文章至少包含 1 个通用语),尽管大多数文章没有提到样本人口统计学信息。通用语在论文的较短单元(即重点比摘要)中出现得更频繁,而且通用语与样本大小无关。研究 2 至 4(=1578)发现,读者认为用通用语言表达的结果比用非通用语言表达的结果更重要和更具普遍性。我们强调了科学交流中语言选择的潜在意外后果,以及这些选择如何反映科学家对其数据的看法。
