This study aimed to investigate whether dispositions to positive affect (PA), mindfulness, and flow states predict a disposition toward insight. Using a sample of 1069 participants, two structural equation models (SEMs) were performed; the first included positive affect, mindfulness, and flow as the predictors. The second SEM repeated this, but with the nine components of flow included separately. In the first model, mindfulness and flow significantly predicted insight; PA showed no effect. In the second model, PA and mindfulness showed an effect. The subcomponents of flow—merging of action and awareness, unambiguous feedback, and transformation of time—had the strongest effect on insight, followed by autotelic experience. Clear goals negatively affected insight.
