A March study published in Psychology and Aging, a respected American journal, tracked 100 University of Rochester students from the 1970s across key life stages—at ages 20, 30, and 50.
Participants logged their daily social interactions, noting the degree of intimacy and any associated inconveniences. At 50, they also reported on psychological well-being, including loneliness, depression, and friendship quality.
The findings? The quantity of interactions at 20 (not quality) and the quality of interactions at 30 (not quantity) best predicted psychosocial health at 50.
In our 20s, we crave connections, building broad networks. By 30, priorities shift: we prune superficial ties for deeper bonds.
Abundant interactions in your 20s benefit later life. But persistent shallow socializing post-30 correlates with greater loneliness, sadness, and poorer well-being at 50, per the research.
Though the sample was modest (just 100 participants), it raises timely questions amid social media's rise. A separate U.S. study of 25,000 people found no shift in friendship depth or perception.
