 At the same time, Richard Pildes and Elizabeth Anderson caution against wholeheartedly adopting this analogy.

In turn, Pildes and Anderson argue that “individuals need to participate actively in democratic institutions to enable them to achieve a rational ordering of their preferences for collective choices” (1990, 2177).
