The fascinating world of human behavior often leaves us with mind-boggling questions. One such intriguing aspect is the widespread human tendency towards cooperation. Unlike most animals, humans are remarkably cooperative creatures. This article delves into the reasons behind our cooperative nature, as explained by behavioral science, and explores how this understanding can be harnessed to solve global problems.

Humans: The Cooperative Species

On a daily basis, we encounter innumerable examples of cooperation. We halt our vehicles when the traffic light turns red. We share public transport with a sea of strangers without causing chaos. We even abide by taxation rules and contribute to charities. These routine actions are often taken for granted, but they highlight an extraordinary facet of human behavior: cooperation.

Contrary to other species, humans exhibit profound cooperative tendencies. According to Michael Muthukrishna, a behavioral scientist at the London School of Economics, even the least cooperative human groups outshine our closest cousins, chimpanzees and bonobos, in terms of cooperation.

The Conundrum of Cooperation

Cooperation, while being a distinguishing trait of humans, also presents an intriguing paradox. People who act cooperatively expose themselves to exploitation by others. Yet, worldwide, societies see people cooperating for mutual benefit. The key to this puzzle lies in understanding the conditions that promote cooperation.

Behavioral scientists define cooperation as bearing a personal cost (like donating to a charity) to achieve a collective benefit (a social safety net). However, freeloaders can enjoy the same benefit without bearing the cost. So theoretically, freeloaders should have the upper hand. So why then, do we see cooperation being a prevalent strategy?

Evolution and Cooperation: A Shared Journey

The answer to the cooperation paradox lies in the process of evolution. Our cultural and genetic evolution has equipped us with tools to overcome the potential drawbacks of cooperation, making it a ‘smart move’ and not a ‘sucker’s choice’. This has led to the formation of villages, cities, farms, and governments, all of which rely on extensive cooperation among individuals.

The unwritten societal rules or norms, our indignation when these norms are violated, and our concern for our reputation are all results of evolution. “Over the long haul, human psychology has been modified so that we’re able to feel emotions that make us identify with the goals of social groups,” says Rob Boyd, an evolutionary anthropologist at the Institute for Human Origins at Arizona State University.

The Power of Reputation and Norms

In large societies where people often interact with strangers, reputation plays a crucial role in encouraging cooperation. Norms, or informal rules of behavior, become important in larger groups where people can’t rely on personal experiences or knowledge of others’ reputations. Violating norms can lead to social disapproval, ranging from mild criticism to outright ostracism.

However, norms may have limitations. “The enforcement of norms depends on social disapproval of violators, so they work only within social groups. Since nations are the largest groups that most people identify strongly with, that may make norms relatively toothless in developing international cooperation for issues such as climate change,” says Erez Yoeli, a behavioral scientist at the MIT Sloan School of Management.

The Role of Gossip in Enforcing Norms

Gossip, or sharing information about a third party when they are not present, can be a powerful tool in enforcing social norms. Negative gossip can influence people’s perceptions and make them less likely to interact with those who violate norms.

The Trend Factor

Telling people what others actually do is more effective in encouraging cooperation than telling them what they should do. If most people don’t choose a socially desirable behavior, such as installing solar panels, highlighting an increasing trend towards that behavior can nudge people towards it.

The Road Ahead

While we’ve made strides in understanding cooperation, many questions remain. For instance, we know little about why certain norms prevail in cultures or how norms change over time. While the ultimate test of survival will determine the norms that endure, understanding and leveraging our cooperative nature is crucial in addressing global issues like climate change and partisan politics.
