We live in enormously polarized times. From politics to race, religion, gender, and class, division runs rampant. In 2020, 40 percent of each political party said that supporters of the opposing party were "downright evil." In 2019, hate crimes reached a ten-year high in the United States. One in five Americans suffers from chronic loneliness, with teenagers and young adults at increasing risk. Social ties at work, at school, and in our communities have frayed. How did we become so alienated? Why is our sense of belonging so undermined? What if there were a set of science-backed techniques for navigating modern social life that could help us overcome our differences, create empathy, and forge lasting connections even across divides? What if there were a useful set of takeaways for managers and educators of all stripes to create connection even during challenging times? Stanford University professor Geoffrey L. Cohen applies his and others' groundbreaking research to the myriad problems of communal existence and offers concrete solutions for improving daily life at work, in school, in our homes, and in our communities.
