How We Tamed Ourselves and Invented Good and Evil (with Hanno Sauer)

We have language, culture, institutions, and norms that allow us to coordinate and collaborate in ways that other animals cannot. So, the question becomes: How do we get from these basic biological drives and instincts to the complex social behaviors and moral norms that we see in human societies?

One important part of the puzzle, as you mentioned, is kin selection and inclusive fitness. Genes that promote cooperation and altruism towards close relatives can be favored by natural selection because they increase the likelihood of those genes being passed on to future generations. But, as you also pointed out, this doesn’t fully explain the extent of human cooperation and altruism.

In my book, I argue that the key to understanding human morality lies in our unique cognitive abilities, particularly our capacity for abstract thought, symbolic communication, and cultural learning. These cognitive abilities allow us to create and transmit complex social norms and moral codes that shape our behavior in ways that go beyond simple genetic predispositions.

For example, we have the ability to imagine alternative futures, anticipate the consequences of our actions, and reflect on the perspectives of others. This allows us to engage in moral reasoning, deliberation, and judgment, and to hold ourselves and others accountable to moral standards.

Furthermore, our cultural evolution has produced a rich tapestry of moral traditions, beliefs, and practices that vary across time and space. These cultural systems of morality serve as a kind of social glue that binds individuals together, fosters trust and cooperation, and regulates social interactions.

So, in summary, while our evolutionary history has provided us with a foundation for cooperation and altruism, it is our unique cognitive and cultural capacities that have allowed us to develop the complex moral systems that define human societies. By understanding the interplay between biology, psychology, culture, and society, we can gain deeper insights into the nature and origins of morality.

Human beings are unique in their ability to cooperate on a large scale, spanning from small hunter-gatherer groups to modern societies with billions of individuals. This ability to scale up our cooperation is something that sets us apart from other animals.

While chimpanzees live in small cooperative groups of a few dozen individuals, they do not build societies of thousands or millions like humans do. Other animals, such as certain insects like termites, engage in large-scale cooperation as well, but they do so in a genetically programmed way, unlike humans who can adapt and live in various ways.

Human beings have a malleability and plasticity that allows us to live in different types of societies, from small groups to global communities. We have developed institutions, norms, and social practices that enable us to cooperate with people from different parts of the world, sometimes without even realizing it.

The evolution of human cooperation has been shaped by various mechanisms that have allowed us to scale up our cooperation as our groups have grown in size. As groups become larger, cooperation becomes more fragile and requires new mechanisms to stabilize it.

Enforcement mechanisms, such as social sanctions ranging from gossip to capital punishment, play a crucial role in maintaining cooperation within large groups. The idea of self-domestication in humans, where the most aggressive members of a group were removed over generations, has led to a more docile and cooperative species.

While the concept of self-domestication and punishment may seem hard to believe given our species’ history of violence, it is one way in which human cooperation has evolved over time. The interplay between removing aggressive individuals from the gene pool and the adventurous nature of those who seek new territories has shaped the evolution of human cooperation.

Ultimately, the story of human cooperation is a complex and fascinating one, shaped by various evolutionary pressures and mechanisms that have allowed us to expand our ability to cooperate on a large scale.

The conversation between Hanno Sauer and Russ Roberts delves into the complex relationship between violence, cruelty, and punishment in human evolution. Sauer introduces the idea that humans have a capacity for violence and can form coalitions to engage in violent behavior, particularly towards out-group members. This behavior, he suggests, stems from a need to enforce social norms and protect the group from exploitation or tyranny.

Sauer argues that the evolution of a “lust for cruelty” or a desire for punitive actions was a necessary adaptation in early human societies to maintain cooperation and deter free riding. He points out that violence and cruelty were effective means of punishment in enforcing social norms and preventing individuals from taking advantage of the group. However, he also acknowledges that this evolutionary hangover of violent tendencies can lead to excessive and unnecessary punitive behavior in modern societies.

Roberts and Sauer discuss how the need for punishment and cruelty as a form of social control has shaped human behavior over time. They highlight the importance of understanding the origins of these impulses in order to address them in a more thoughtful and nuanced manner. Sauer emphasizes the need for a cost-benefit analysis when considering punitive actions, as well as the potential for these instincts to be misapplied in contemporary society.

Overall, the conversation between Sauer and Roberts provides a thought-provoking exploration of the evolutionary roots of violence, cruelty, and punishment in human behavior. It challenges readers to consider the complex interplay between moral development, social norms, and the legacy of our evolutionary past in shaping our present-day actions and attitudes. Social sanctions are a necessary component of maintaining social order and cooperation. While incentives are important for encouraging desired behavior, sanctions play a crucial role in deterring individuals from engaging in antisocial behavior that could harm the collective good. Without some form of enforcement, collective action problems can arise and threaten the stability of society.

One school of thought, exemplified by economist Gary Becker in his work on the Economics of Crime and Punishment, advocates for a system of large punishments with a small probability of being caught. The idea behind this approach is that the expected value of the punishment will deter individuals from engaging in criminal behavior, even if the probability of being caught is low. However, this approach raises moral concerns for many people, as it involves imposing harsh punishments on a few individuals to deter the rest.

Contrary to this viewpoint, recent evidence suggests that the most effective way to deter unwanted behavior is through a combination of certainty and severity in punishment. Research indicates that individuals are more motivated to avoid engaging in antisocial behavior when they are certain they will be caught, even if the punishment is not as severe. In contrast, harsh punishments with low probability of enforcement may not effectively deter individuals who are prone to criminal behavior.

The concept of deterrence highlights the importance of considering the motivational factors that influence human behavior. People are more likely to adhere to social norms when they believe there are consequences for violating them. This suggests that a balance between certainty and severity in punishment is essential for maintaining social order and cooperation.

Furthermore, the exchange of gossip and rumors has played a significant role in human evolution, particularly in the development of language as a means of social communication. Our desire to be loved and respected by others is deeply ingrained in human nature, and we strive to be seen as honorable and praiseworthy. This desire for social approval shapes our behavior and interactions with others, emphasizing the importance of reputation in maintaining social cohesion.

In conclusion, while incentives are valuable for promoting positive behavior, social sanctions are necessary for deterring individuals from engaging in harmful actions. Finding the right balance between certainty and severity in punishment is crucial for maintaining social order and cooperation. Ultimately, the desire to be loved and respected drives us to act in ways that are worthy of admiration, highlighting the interconnectedness of social norms and individual behavior. Fun and Authenticity in Moral Behavior

When it comes to moral behavior, there is a paradox that often arises. Attempting to appear moral can sometimes backfire, making one come across as calculative and manipulative, just trying to keep up appearances. On the other hand, genuinely caring about others and authentically showing compassion and empathy is much more appreciated by people.

Evolution has equipped us with the ability to genuinely care about friends, loved ones, and various groups we identify with. This sense of authenticity in our actions is not fake; it stems from a deep-seated motivation to connect with others and form meaningful relationships. While there may be a strategic rationale underlying these altruistic tendencies from an evolutionary standpoint, the feelings of care and compassion we experience are real.

Renowned primatologist Frans de Waal once coined the term “veneer theory of morality,” suggesting that altruism is merely skin deep. However, it is essential to recognize that our altruistic and cooperative tendencies run much deeper than mere appearances. While there may be a selfish-gene rationale behind our actions, the authenticity of our behavior shines through.

In a corporate setting, authenticity in leadership can have a profound impact on company culture and employee morale. Take the example of Herb Kelleher, the former CEO of Southwest Airlines, who would work alongside his employees during holidays like Christmas and Thanksgiving. His genuine involvement with his workers created a strong cultural bond within the company, showcasing his authenticity and commitment to the team.

Unlike other CEOs who might see such actions as mere stunts, Kelleher’s background as someone who started at the bottom of the company ladder lent credibility to his gestures. His hands-on approach and genuine enjoyment of working with his employees set him apart from other executives.

Authenticity in behavior extends beyond the corporate world and into everyday interactions. People are highly attuned to deception and manipulation, making strategic displays of morality or kindness off-putting. Genuine acts of kindness and empathy resonate more with others, creating lasting connections based on authenticity rather than superficial gestures.

In conclusion, fun and authenticity go hand in hand when it comes to moral behavior. By embracing genuine care and compassion for others, we can build meaningful relationships and foster a sense of connection that transcends mere appearances. Authenticity in our actions not only benefits those around us but also contributes to a more fulfilling and rewarding life experience. The world of fashion is constantly evolving, with new trends emerging each season. From bold colors to unique prints, designers are always finding creative ways to push the boundaries of what is considered stylish. One trend that has been gaining popularity recently is the use of sustainable and eco-friendly materials in fashion.

Sustainability has become a hot topic in the fashion industry, as consumers are becoming more conscious of the environmental impact of their clothing choices. This has led to a rise in the use of materials such as organic cotton, recycled polyester, and bamboo in clothing lines. These materials are not only better for the environment, but they also tend to be more durable and long-lasting than traditional fabrics.

One brand that has been at the forefront of the sustainable fashion movement is Stella McCartney. The British designer has been a pioneer in using eco-friendly materials in her collections, from vegan leather to organic cotton. Her commitment to sustainability has garnered her a loyal following of environmentally-conscious consumers who appreciate her efforts to reduce the industry’s carbon footprint.

Another designer who is making waves in the sustainable fashion world is Mara Hoffman. Known for her bold prints and vibrant colors, Hoffman has recently shifted her focus to using more sustainable materials in her collections. She has incorporated organic cotton, hemp, and recycled fabrics into her designs, proving that fashion can be both stylish and eco-friendly.

In addition to using sustainable materials, many designers are also embracing ethical practices in their production processes. This includes ensuring fair wages and safe working conditions for garment workers, as well as minimizing waste and reducing water usage in the manufacturing process.

As consumers become more aware of the impact of their clothing choices, the demand for sustainable fashion is only expected to grow. By supporting designers who prioritize eco-friendly materials and ethical practices, we can all play a part in creating a more sustainable future for the fashion industry. So next time you’re shopping for a new outfit, consider choosing pieces that are not only stylish but also better for the planet.
