Friendships are key to our well-being, but what kind of friendships do we really want? Despite being such a foundational part of the human experience, the science of friendship is still mysterious. Assistant professor of psychology Jessica Ayers is trying to fill in the blanks. While it’s long been assumed that people want either a few close friends or a large network of friendships, her recent research shows that many people need a mix of both friendship types to feel connected. Her research points to new ways we can understand our own friendship styles and gives insight to the loneliness epidemic.
