Connecting the Dots: Rectifying the Disconnect Between the Situational Strength and Situational Substance Literatures

Despite considerable and ever-growing interest in situational influences on behavior, research on situational strength remains siloed from research on situational substance (i.e., content). This review paper examines the complex interplay between situational strength and substance, bridging existing disciplinary boundaries. Through an analysis of contemporary person-situation interaction theories and models, we identify and elaborate on two competing perspectives: one positing situational strength and substance as relatively orthogonal concepts, and the other suggesting a linear or quadratic functional association between the two concepts. Our examination reveals significant gaps in current understanding of situational strength and substance, particularly regarding how different situational characteristics interact to shape behavioral outcomes. By synthesizing insights from varied theoretical frameworks, such as Trait Activation Theory (Tett & Burnett, 2003), Cognitive-Affective Processing System theory (Mischel & Shoda, 1995), and Nonlinear Interaction of Person and Situation theory (Blum et al., 2018), we argue for a more nuanced, integrated approach to studying situations. To accelerate progress, we propose research strategies that bridge existing theoretical divides, emphasizing the need for more sophisticated methodological approaches aimed at examining the essence of situations.
