How social norms come into being
Fifteen years ago, the name “Aiden” was hardly on the radar of Americans with new babies. It ranked a lowly 324th on the Social Security Administration’s list of popular baby names. But less than a decade later, the name became a favorite, soaring into the top 20 for five years and counting. Now, a new study provides a scientific explanation for how social conventions — everything from acceptable baby names to standards of professional conduct — can emerge suddenly, seemingly out of nowhere, with no external forces driving their creation.
