In a recent conversation with my spouse, I found myself reflecting on my time in the Marine Corps and the unique way in which Marines interact with each other. My wife, often taken aback by the stories of insults and roughhousing among Marines, questioned why we were always so harsh towards one another. My immediate response? “For the same reason monkeys poke each other in the eyes.”
This seemingly cryptic explanation stems from a book I had recently read titled “Games Primates Play: An Undercover Investigation of the Evolution and Economics of Human Relationships.” The book delves into the social behaviors of primates and how they mirror human interactions. One common behavior among primates is loyalty signaling through the infliction of minor harms. By allowing another monkey to prod or poke vulnerable areas without causing harm, trust and alliance are built. This concept of signaling trust through controlled harm was evident in Marine culture as well.
In the Marines, insults and rough play were not signs of animosity, but rather signals of camaraderie and trust. The unspoken agreement was that one could insult or engage in physical roughhousing with a fellow Marine, knowing that it was all in good fun. This behavior, while extreme in the military, follows a similar pattern seen in friendships outside of the military. As relationships deepen, teasing, joking, and pranking become ways to signal closeness and trust.
However, these forms of friendly antagonism also serve a vital purpose in building social cohesion, especially in high-pressure environments like the military. The ability to let down walls and engage in playful banter creates a bond that is crucial for survival in life-and-death situations. This bonding process, while seemingly harsh to outsiders, is essential for fostering a sense of unity and camaraderie among individuals.
Despite efforts to promote a kinder and gentler form of social interaction, the deeply ingrained nature of these behaviors in our evolutionary psychology suggests that they serve a crucial purpose in building and maintaining social bonds. Attempts to suppress or eliminate mildly antagonistic forms of friendship signaling may actually weaken the fabric of social cohesion rather than strengthen it.
In conclusion, the unique way in which Marines interact with each other, characterized by insults, rough play, and practical jokes, serves a deeper purpose beyond mere amusement. It is a form of signaling trust, camaraderie, and unity that is essential for navigating the challenges of military life. This behavior, rooted in our evolutionary past, highlights the importance of understanding the role of friendly antagonism in building strong social bonds.
