#Siblingrelationships

In a shift from the long-held belief that parenting is the primary force in determining a child’s outcomes, a growing body of research indicates that siblings may play an equally significant—if not greater—role in molding each other’s personalities, achievements, and life trajectories. This fresh perspective, featured in the latest cover story of The New York Times Magazine, draws on a range of recent studies examining the “sibling spillover effect,” and is prompting both researchers and families globally, including those in Thailand, to reconsider just how children influence one another within the family unit (NYTimes).

A growing body of research challenges the idea that parenting is the sole driver of a child’s outcomes. Studies on the “sibling spillover effect” indicate that brothers and sisters can influence each other’s personalities, achievements, and life paths as much as, or even more than, parents. The latest adaptation of this theme appears in a recent cover story by The New York Times Magazine, drawing on multiple studies to explore how siblings shape one another. In Thailand, as in many countries, families are rethinking how sibling relationships contribute to development and success.
