The Invisible Influences on Decision-Making explores the often unseen factors that influence decision-making in both everyday life and various professional settings, with a particular focus on policing, medicine, education, and counselling. Chitpin and Dougan present key findings and trends in decision-making research, then go on to explore the concept of indecisiveness before examining decision-making processes in these specific professions. The authors employ qualitative research methodologies, such as case studies and phenomenology, alongside social influence theories, to provide a nuanced and current understanding of decision-making within these fields. By incorporating perspectives from professionals, chapters aim to enhance public understanding and confidence in how decisions are made in these critical areas, especially within a Canadian context. While there is existing literature on decision-making in community service professions, it often remains discipline specific. The Invisible Influences on Decision-Making addresses the need for more inter-professional and interdisciplinary research, highlighting the collaborative nature of these professions and the complexities of their decision-making processes. By integrating real professional examples with research and theory, this study offers a compelling and insightful narrative that will engage researchers, practitioners, and graduate students across various fields.
