Relative Rank Theory: A Computational Model of Preferences, Choices, Attitudes and Opinions (EU Horizon 2020 Project)

Our differing preferences and attitudes make each of us unique. But how are our everyday choices related to our preferences, and how are the opinions that we express related to our underlying attitudes? In particular, how can we understand the phenomenon of opinion polarisation (as seen, for example, in people's opinions since the Brexit referendum in the UK), and how can we understand stable individual differences in people’s everyday choices when those choices are so strongly influenced by the context that the market provides?

This page summarises progress on our European Research Council (ERC) grant awarded under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 788826) which is addressing these and related questions. Information will be added to this website as the project progresses.
