Mapping and Measuring Deliberation: Towards a New Deliberative Quality

Deliberative democracy has challenged two widely-accepted nostrums about democratic politics: that people lack the capacities for effective self-government
and that democratic procedures are arbitrary and do not reflect popular will
indeed, that the idea of popular will is itself illusory. On the contrary, deliberative democrats have shown that people are capable of being sophisticated, creative problem solvers, given the right opportunities in the right kinds of democratic institutions.

But deliberative empirical research has its own problems. In this book two leading deliberative scholars review decades of that research and reveal three important issues. First, the concept 'deliberation' has been inflated so much as to lose empirical bite
second, deliberation has been equated with entire processes of which it is just one feature
and third, such processes are confused with democracy in a deliberative mode more generally. In other words, studies frequently apply micro-level tools and concepts to make macro- and meso-level judgements, and vice versa.

Instead, Bachtiger and Parkinson argue that deliberation must be understood as contingent, performative, and distributed. They argue that deliberation needs to be disentangled from other communicative modes
that appropriate tools need to be deployed at the right level of analysis
and that scholars need to be clear about whether they are making additive judgements or summative ones. They then apply that understanding to set out a new agenda and new empirical tools for deliberative empirical scholarship at the micro, meso, and macro levels.
