Bestselling author Cass R. Sunstein reveals the appeal and the danger of conformity We live in an era of tribalism polarization and intense social divisionseparating people along lines of religion political conviction race ethnicity and sometimes gender. How did this happen In Conformity Cass R. Sunstein argues that the key to making sense of living in this fractured world lies in understanding the idea of conformitywhat it is and how it worksas well as the countervailing force of dissent. An understanding of conformity sheds new light on many issues confronting us today the role of social media the rise of fake news the growth of authoritarianism the success of Donald Trump the functions of free speech debates over immigration and the Supreme Court and much more. Lacking information of our own and seeking the good opinion of others we often follow the crowd but Sunstein shows that when individuals suppress their own instincts about what is true and what is right it can lead to significant social harm. While dissenters tend to be seen as selfish individualists dissent is actually an important means of correcting the natural human tendency toward conformity and has enormous social benefits in reducing extremism encouraging critical thinking and protecting freedom itself. Sunstein concludes that while much of the time it is in the individuals interest to follow the crowd it is in the social interest for individuals to say and do what they think is best. A wellfunctioning democracy depends on it.
