Most literature on sport fan behaviors has focused on highly identified or loyal sport fans. While the literature has found that factors influencing current sport fans and their behaviors are related to, and based on, various psychological, social, and cultural factors, only a limited number of studies have investigated what factors initially attract individuals to consume sport. Curiosity has been found to be one of the crucial motivators that initially influence human exploratory behaviors in many domains. Using theories of curiosity, the present review aims to shed light on the role of curiosity in explaining various sport fan behaviors.
