“But the most interesting part of Thorne’s experiment was how much the two types appreciated each other. Introverts talking to extroverts chose cheerier topics, reported making conversation more easily, and described conversing with extroverts as a “breath of fresh air.” In contrast, the extroverts felt that they could relax more with introvert partners and were freer to confide their problems. They didn’t feel pressure to be falsely upbeat. These are useful pieces of social information. Introverts and extroverts sometimes feel mutually put off, but Thorne’s research suggests how much each has to offer the other. Extroverts need to know that introverts—who often seem to disdain the superficial—may be only too happy to be tugged along to a more lighthearted place; and introverts, who sometimes feel as if their propensity for problem talk makes them a drag, should know that they make it safe for others to get serious.”
