Current research

Every day, millions of humans make decisions about issues of interest for the group or the community they represent. Equivalent processes have been described well by several authors for animal societies. Group members must take decisions satisfying the majority of individuals (i.e. decision accuracy) but in a relative short period (i.e. decision speed). Much time may be required to make an accurate decision between alternatives, because evaluating information may be a lengthy process. Nevertheless, empirical studies demonstrating the conflict between speed and accuracy in decision making are mostly investigations in the field of human performance and psychology. Several factors can affect this trade-off between speed and accuracy. Better information can enhance the efficiency of the decision. However, the decision efficiency also depends on the way individuals are inter-connected, that is, according to the social network. I want to assess how the information quality and social network may enhance the collective decision-making by increasing both the accuracy and the speed of the decision.
