“Modeling contributed little to policymaking during the last crisis because few of us understand that process and even fewer policymakers understand ours. I attended several SARS workshops, one right here. One could infer – from our presentations – we believed policymakers wanted to know what R0 was and if the equilibria of arbitrary models were locally, if not globally stable. As they actually needed help deciding what to do, we contributed very little to their global response."
