Why we like people less as we age — science explains

I’ll never forget my first family reunion in my thirties: standing among dozens of distant cousins, I found myself ducking out early, craving a quiet cup of tea rather than another round of small talk. It turns out, I’m not alone. Researchers analysed anonymised call logs from a European mobile-operator, covering some 3.2 million users, to map how social engagement shifts over the life course¹. Their findings suggest that as we grow older, our appetite for superficial chit-chat genuinely declines. In fact, what looked for years like an adult version of teenage aloofness may instead be a natural shift in our life stages.

According to the study, by midlife, many of us are unknowingly sieving out relationships that feel futile, reserving our energy for the people who truly matter. This isn’t about turning into curmudgeons; it’s about focusing on authentic connections rather than chasing every invitation that comes our way.

Are we less sociable over time?

Delving deeper, the researchers tracked call-frequency data and discovered a steady drop in total contacts after the mid-twenties, balanced by a sharper rise in calls to top-ranked alters². In other words, while the size of our social circle shrinks, the quality of interactions goes up. This “unconscious filtering” kicks in as early as our thirties and intensifies through middle age.

Why does this happen? Partly, it’s a matter of selectivity. With responsibilities piling up—careers, mortgages, family commitments—people become less patient with small talk that doesn’t enrich their lives. Instead of saying “yes” to every gathering, many now ask: “Will this add value, or just eat into my free time?” It’s not bitterness; it’s wisdom, backed by socioemotional selectivity theory, which shows that as we perceive our time as shorter, we prioritise emotionally meaningful goals over broad social exploration³.

By recognising this natural evolution, we can let go of any guilt about skipping that tenth party of the month. After all, as the study authors point out, prioritising the right people is simply a healthier way to navigate adulthood—and one that science fully supports.
