Self-reported data about communication, trust and sympathy in a newly formed team have been gathered with the intention of evaluating the influence of sympathy and trust on communication patterns in the team. The principal component analysis shows that most of the variation across all studied aspects can be explained by one factor that is best interpreted as sympathy.
However, the greater reliability of the sympathy measure indicates that the frequency of communication between people is not driven only by sympathy but by other factors as well. It is discussed that the influence between sympathy and communication may work in both directions.
Finally, based on the correlations and PCA it is argued that the self-reported desired frequency of communication can be a good proxy for mutual sympathy in case people are reluctant to report it
