Sortition and cognitive ability

There is a growing sense that representative democracy is in crisis, leading to renewed interest in alternative institutional designs. One popular proposal—what I call legislative sortition —says we should replace elected legislators with randomly selected citizens. While legislative sortition has drawn both numerous supporters and critics, one objection has received little attention: that ordinary citizens’ lower cognitive abilities, relative to elected officials, will diminish the quality of governance. This paper articulates and evaluates this concern, distinguishing between several versions of it. I argue that some forms of the objection are implausibly strong, but that a suitably qualified version can be defended. Although this does not provide a decisive reason to reject legislative sortition, it meaningfully shapes how we should assess its promise.
