Traditional social choice has concerned itself with aggregating discrete outcomes via voting. Increasingly, there is a need to aggregate opinions. For instance, consider the problem of designing the capital budget of a city or country. Or eliciting what trade-offs are worth making to mitigate the effect of climate change. On such issues, there are a spectrum of opinions, most of which are quite complex, and many of which are ill-informed.
At the same time, crowdsourcing and complex polling are in increasing use for subjective opinion: examples are prediction markets, peer assessment, and Bayesian opinion elicitation in the presence of incentives.
This leads to questions like:
The goal of this workshop is to bring together participants from diverse fields that are relevant to such problems -- social choice theory, prediction markets, opinion dynamics, and fair resource allocation in order to foster a lively interchange of ideas. The two essential features of work discussed at this workshop are:
Papers from a rich set of empirical, experimental, and theoretical perspectives are invited.
