Using new data from the National Sports and Society Survey ( N = 3993), this study first examines the extent to which US adults recognize that sports teach love of country, competition as a way of life, respect for the military, and how to be American. We characterize this sport and society process as American Institutionalized Sports Nationalism. Then, multiple regression analyses are used to assess the extent to which dominant statuses, indicators of traditionalism, and sports fandom are associated with beliefs about American Institutionalized Sports Nationalism and its component values. Results suggest that US adults commonly agree that sports teach love of country, competition as a way of life, respect for the military, and how to be American; they are especially likely to agree that sports teach competition as a way of life and love of country. Many US adults also recognize sports as teaching respect for the military and how to be American, but most do not. In addition, as expected, identifying as male, heterosexual, Christian, Republican, and as more of a sports fan is consistently and positively associated with agreeing that sports teach patriotic, capitalistic, militaristic, and nationalistic values. In contrast to expectations, we find evidence that White adults are less likely than Black and Latinx adults to recognize American Institutionalized Sports Nationalism and its component values; college educated adults are also less likely than those with a high school education or less to agree that sports teach patriotism, capitalism, militarism, and nationalism. This may be because sports have traditionally been perceived to offer rather inclusive and fair social and economic opportunities for non-Whites and the less educated. Regardless, it is important to continue to research which cultural messages are promoted through sports, why, and to what effect. The present study advances this research initiative.
