Social intelligence, a neurological system?

Social intelligence has been researched for almost 70 yr. without definitive findings. During this period almost no attempts have been made to consider the complexity of the brain's anatomy and functions responsible for social competence. An ecological model focusing on social abilities within a biopsychosocial context is discussed along with supporting literature and an hypothesis for research. This argument invokes social intelligence as an independent brain system. It is suggested that neurological structures and chemical activities controlling social skills are directly influenced by the environment, individual beliefs, personal goals, and physiology.
