Someone who desires to live outside of established social hierarchies is actually Sigma meaning. Sigma guys are lone wolves, autonomous, self-sufficient, and frequently introverted, in contrast to Alpha males who take the lead or Beta males who follow. They are self-assured and goal-oriented, but they don't look for attention or acceptance. Sigma guys prefer independence to dominance and flourish in solitude. People who value sincerity and personal development over conformity or social climbing would find this personality type appealing.
