, We discussed decision-making processes, how "idealized" modeling prevents an adequate understanding of these processes, and alternative methodologies for a new understanding of them. The meeting was funded by the EU FP7 Co-ordination Action grant 266723 Global System Dynamics and Policy (GSDP), whose support is gratefully acknowledged. David Tuckett also wishes to acknowledge support from the Institute of New Economic Thinking (grant no. IN01100025) and the Anna Freud Centre. A follow-up meeting was generously aided by the University Paris 1 Panthéon-Sorbonne and the EU Co-ordination Action, 296777.
