I found I could really relate to the things she spoke about in her book about the social bias in society that benefits extroverts, and makes introverts feel they must act more extroverted than they are naturally. Having studied psychology at school I was able to easily make sense of the research in the book and I think that the messages contained in the book should really be widely recognised.
Having read her book I also followed Susan Cain on twitter, and I enjoy reading her tweets and the articles and research she often posts. Today she shared an article about research that suggests that being a good listener helps you to exert influence over people. I think this is an important point for PR practitioners to remember and that a lot of her research can be taken into account for the practice of PR. It is likely that introverts and extroverts may respond differently to PR campaigns.
