CfP special issue of "Social Choice and Welfare" on deliberation & aggregation, Deadline: 15 Nov 2020

*Call for Papers: Special Issue of Social Choice and Welfare: Deliberation 
and Aggregation*

Authors are invited to submit papers that contribute to understand how, 
and when, deliberation and aggregation can be conjoined in order to arrive 
at better processes of collective attitude formation. Social Choice and 
Welfare (SCW) mainly publishes high-quality papers studying models of 
welfare economics and collective choice. Conceptual or philosophical 
papers that are of exceptional quality and close to the core topics of the 
journal will also be considered for this special issue.

Deadlines:
Paper Submission Deadline: November 15th, 2020

Submit complete papers for peer review through the SCW online submission 
system. Submissions should be prepared following the SCW submission 
guidelines: https://www.springer.com/journal/355/submission-guidelines.

Submissions accepted before the completion of the issue will be publicly 
available on SCW?s  ?Online First? section.

Background.

Preferences and beliefs are routinely attributed to groups. A jury can
believe the accused to be guilty, and a professional board can
officially voice its disapproval of certain practices by its members.
The special issue aims at putting together contributions that take steps
towards bridging the gap between the two main paradigms in formal
philosophy and economics on the formation of such collective attitudes:
the deliberative and aggregative views. On the deliberative view, group
attitudes stem from a consensus reached after a (more or less)
structured exchange of opinions. On the aggregative view, group
attitudes are formed by putting together the possibly diverging views of
individuals, through a formal voting procedure for instance.

Deliberation and aggregation are typically both involved in collective
attitude formation. We cannot deliberate endlessly. When disagreements
persist, aggregating, e.g. by voting, might be the only way to arrive at
a group opinion. So deliberation and aggregation are not competing, but
complementary approaches. Up to now, however, they have mostly been
studied separately. This is an important limitation, and many authors
have defended the view that deliberation and aggregation can enhance
each other: Deliberation can support meaningful aggregation, for
instance by preventing preference cycles. On the other hand specific
forms of aggregation can possibly help overcome some of the negative
effects of deliberation, for instance by minimizing strategic behavior
in deliberation, or attenuating the effects of polarization and groupthink.

The goal of this special issue is to put together a number of original
articles that further our understanding of how, and when, deliberation
and aggregation can be conjoined in order to arrive at better processes
of collective attitude formation. The overarching question is how
deliberation can be better geared towards aggregation, and how to enrich
current models of belief and preference aggregation to make them more
amenable to the results of deliberation.
