Human communication has shifted to texts from phone calls - in the U.S. the number of text messages exploded from 14 billion in 2000 to 188 billion in 2010. Prof. Balázs Kovács from Yale University gave a lecture at CNS about the role of language style in human interactions.
It is known that homophily, the tendency that friendship is more likely to form between similar people, shapes social networks. Prof. Kovács demonstrated in two examples how linguistic similarity enforces network tie formation and friends exhibit linguistic convergence over time.
