The deliberative model of democracy, as presented by Jürgen Habermas and others, claims to reconstruct the normative content of the idea of democracy. However, since it overemphasises the epistemic facet of decision‐making, the model is unable to take into account other valuable aspects of democracy. This is shown in reference to two concrete phenomena from political reality: majority voting and the problem of the dissenter. In each case, the deliberative model inevitably fails to account for several normatively desirable features of (...) democracy, such as formal political equality and proper respect for the judgement of each citizen.

ABSTRACT The rise of social media has correlated with an increase in political polarization, which many perceive as a threat to public discourse and democratic governance. This paper presents a framework, drawing on social epistemology and the economic theory of public goods, to explain how social media can contribute to polarization, making us collectively poorer, even while it provides a preferable media experience for individual consumers. Collective knowledge and consensus is best served by having richly connected networks that are epistemically (...) integrated: individuals with diverse levels of expertise should be relatively well connected to each other. In epistemically segregated networks, by contrast, we have reason to predict collective epistemic failures. Expert knowledge will be isolated from the majority, leading average opinion to be less informed than is socially optimal, and entrenching disagreements. Because social media enables users to very easily adopt homophilous network connections – connections to those with similar opinions, education levels, and social backgrounds – it is likely to have increased epistemic segregation compared to older media platforms. The paper explains the theoretical foundations of these predictions, and sketches regulatory measures – such as taxes – that might be employed to preserve the public good of a well integrated social media network.
