①We tend to think that friends and family members are our biggest sources of connection, laughter, and warmth. ②While that may well be true, researchers have also recently found that interacting with strangers actually brings a boost in mood and feelings of belonging that we didn't expect.
①In one series of studies, researchers instructed Chicago-area commuters using public transportation to strike up a conversation with someone near them. ②On average, participants who followed this instruction felt better than those who had been told to stand or sit in silence. ③The researchers also argued that when we shy away from casual interactions with strangers, it is often due to a misplaced anxiety that they might not want to talk to us. ④Much of the time, however, this belief is false. ⑤As it turns out, many people are actually perfectly willing to talk—and may even be flattered to receive your attention.
