Mapping collective emotions to make sense of collective behavior.
Taquet M., Quoidbach J., de Montjoye Y-A., Desseilles M.
While Bentley et al.'s model is very appealing, in this commentary we argue that researchers interested in big data and collective behavior, including the way humans make decisions, must account for the emotional factor. We investigate how daily choice of activities is influenced by emotions. Results indicate that mood significantly predicts people's decisions about what to do next, stressing the importance of emotional state on decision-making.
