In this episode of Hidden Brain, host Shankar Vedantam talks with University of Chicago psychologist Nicholas Epley about the paradox of modern life: we are deeply social beings yet often avoid everyday interactions. Epley introduces the term “undersociality,” describing the tendency to miss opportunities for connection. He recounts personal anecdotes—his routine of ignoring fellow commuters, a spontaneous conversation with a woman on a train, and the emotional shock of learning his unborn daughter would have Down syndrome—to illustrate how reaching out can improve mood and provide unexpected support. The conversation then moves to a series of field experiments: a Chicago Metra study where commuters were assigned to talk, stay silent, or act as usual; a London Tube replication; and follow‑up studies showing that people consistently underestimate how enjoyable, rewarding, and informative stranger interactions will be. Personality (introversion/extroversion) does not predict the benefit; acting more extroverted improves well‑being for everyone. Epley also discusses related work on compliments, gratitude letters, repeated compliments, and deep‑vs‑small‑talk interventions, all showing that people over‑predict awkwardness and under‑predict positive impact. He explains the “approach‑avoid” motivational tension and offers practical advice: look for social affordances (e.g., a pear‑picking party, a “compliment calendar,” or a simple observation like an open door) and act on them. Experiments with hedge‑fund executives and scavenger‑hunt style prompts demonstrate that deep conversations can be initiated quickly and are surprisingly well‑received. The episode concludes with strategies for overcoming the initial hesitation to reach out, emphasizing that the cost of avoidance is higher than the perceived risk, and that small changes in mindset can unlock richer, healthier social lives.
