Since the beginning of time, trust holds together our communities. With technology mediating so many of our interactions, more opportunities to deceive one another exist. Is trust one of social media’s most serious casualties? Or is tech is ushering in a new era of trust? This talk draws on psychology and media studies to consider the possibilities. Jeffery Hancock is a professor of communication. He studies the psychology of online behavior, such as deception and trust, emotional dynamics, intimacy and relationships, and social support. Professor Hancock’s work on lying and technology has been featured in numerous media outlets including the New York Times, CNN, and NPR. Classes Without Quizzes are presented by the Stanford Alumni Association. This talk was filmed at Stanford Reunion Homecoming 2016.
