Abstract: I study a Bayesian persuasion model that connects two stylized facts characterizing the Internet: a great diversity of news sources and the proliferation of disinformation. I show that competition between news sources with opposite biases reduces information quality when news consumers have limited attention because of the endogenous formation of echo chambers. According to the standard narrative, echo chambers arise because news consumers exhibit confirmation bias. I show that even unbiased and rational news consumers devote their limited attention to like-minded news sources in equilibrium. Confirmation bias thus arises endogenously because news sources have no incentive to provide valuable information.
