A new mathematical model evaluates the influence of social learners in group decision-making and how a critical threshold is key to informed choices.
Researchers used data of active COVID-19 case rates from China to set the parameters for the model. Applying the formula to other counties, including the UK, France, and Brazil, they found a match in the evolution of active cases and fatality rates over time.
A new model sheds light on the evolutionary origins of empathy and other associated phenomena. The model explains observed patterns of emotional cognition between social group members.
