Recommendation systems are ubiquitous and impact many domains; they have the potential to influence product consumption, individuals{\textquoteright} perceptions of the world, and life-altering decisions. These systems are often evaluated or trained with data from users already exposed to algorithmic recommendations; this creates a pernicious feedback loop. Using simulations, we demonstrate how using data confounded in this way homogenizes user behavior without increasing utility.
