The equal odds baseline is a parsimonious model that describes the relationship between quantity and quality of output in scientific creativity. Specifically, it is posited that quality is a linear function of quantity, and therefore, strong positive correlations between these two variables are expected. Strong positive correlations also play a crucial role in a recurring issue in divergent thinking research: the fluency contamination effect. This effect refers to the problem that any other summative scoring of divergent thinking tests such as the number of original responses (i.e., quality of responses) is confounded by fluency (i.e., quantity of responses). The current work sheds further light into the conceptual overlap between the equal odds baseline, and the fluency contamination effect by demonstrating that a recent formalization of the fluency contamination effect can be used to derive the equal odds baseline. This result is then utilized within a structural equation modeling approach with simulated datasets to thoroughly examine the equal odds baseline. The findings of the structural equation modeling approach are discussed with respect to their potential to better understand the relationship between quantity and quality of productions in creativity research.

论不同思维成绩中的流利性污染效应与科学创造力机会观之间的概念重叠

等赔率基线是一个简约的模型，描述了科学创造力中产出的数量和质量之间的关系。具体而言，假定质量是数量的线性函数，因此，可以预期这两个变量之间的正相关性很强。强烈的正相关在不同思维研究的一个反复出现的问题中也起着至关重要的作用：流利性污染效应。这种影响是指这样的问题，即发散性思维测验的其他任何累加评分（例如原始回答的数量（即，响应的质量））都与流利程度（即，响应的数量）相混淆。当前的工作为等赔率基线之间的概念重叠提供了更多信息，通过证明最近可以将流利污染效应的形式化用于得出等赔率基准，从而实现了流利污染效应。然后，在结构方程建模方法和模拟数据集中利用此结果，彻底检查均等基线。讨论了结构方程建模方法的发现，探讨了它们可能在创意研究中更好地理解产品数量与质量之间的关系的潜力。
