A Conversation on Social Brain Theory and School Size

In a 1993 study, Robin Dunbar, a British anthropologist, theorized that humans could have no more than 150 meaningful relationships, a measure that became known as “Dunbar’s Number.”

Join ISM Consultant Andrew Taylor, Ed.D., and ISM Consultant and Director of Faculty and Curriculum, Josh Nelson, Ph.D., as they discuss this theory as it relates to school size and depth of relationships.
