To this end, academics have created successively more explanatory professional skepticism models. One factor known to cause variations in professional skepticism is affect, yet how it causes these variations is still not understood as the most current models cannot explain why negative affect has been found to both increase and decrease professional skepticism. The purpose of this dissertation is to build a more explanatory model of professional skepticism with respect to affect by asking and answering the question, how does affect produce variations in professional skepticism? To answer the question, I first conduct a review of professional skepticism literature and relevant affect literature to identify affect regulation as a notable theory currently excluded from professional skepticism models. Affect regulation predicts people anticipate affect as it is being generated and change their behaviour to either up- or down-regulate the affect in service of some goal. This is notable as it can explain the contradictory results with respect to negative affect and professional skepticism observed in the literature. I further investigate this with an interview study, the results of which further support the inclusion of affect regulation into a new model of professional skepticism. Then, these insights are combined to create a new model of professional skepticism. Finally, I calibrate the model with an online experiment, the results of which fail to find significant results. Taken together, the new model of professional skepticism developed herein better explains how variations in professional skepticism occur and is of use to those looking to better manage affect to optimize professional skepticism.Author owns copyright, except where explicitly noted.
