Abstract

In this ‘age of information’, some worry that we get our news from online ‘echo chambers’, news feeds on our social media accounts that contain information from like‐minded sources. Filtering our information in this way seems prima facie problematic from an epistemic perspective. I vindicate this intuition by offering an explanation of what is wrong with online echo chambers that appeals to a particular kind of motivated reasoning, or bias due to one’s interests. This sort of bias affects, not which evidence one is exposed to, but how one makes use of the evidence that one has, on the basis of one’s interests. I argue that consulting an online echo chamber often facilitates and amplifies this bias. I then draw some general conclusions about the potential downside of having ready access to so much information.
