TREE Opinion on confidence and collective decision-making

A new Opinion on individual confidence and collective decision-making is in press in Trends in Ecology and Evolution, authored by James together with Andy Radford (Bristol) and Gavin Brown (Manchester).

The Opinion argues for the consideration of subjective confidence and its influence on communication within collectively-deciding groups. The Opinion also draws links between confidence by individually-optimal decision-makers, and the optimal confidence-based weighting scheme for group decisions.

Collective Behaviour Minisymposium

Thomas, James and Giovanni co-organised a minisymposium on Collective Behaviour and Decision Making, at the 2017 Mathematical Models in Ecology and Evolution conference in London.

The speakers covered a diverse range of topics, from naming games to building the Matrix for fish. The full list of speakers and titles is as follows:

  • Andrea Baronchelli (City University London) – The spontaneous emergence of conventions
  • Andreagiovanni Reina (University of Sheffield) – A model of the best-of-N nest-site selection process in honeybees
  • Arianna Bottinelli (Nordic Institute for Theoretical Physics) – The breakdown of coordination and the emergence of dangerous collective motions in high-density crowds
  • Colin Torney (University of Glasgow) – Cues and collective decision-making in migrating ungulates
  • Renaud Bastien (University of Konstanz) – A simple model of collective behaviour driven by the visual field
