Nonzero: The Logic of Human Destiny - Study Guide

Quiz

Answer the following questions in 2-3 sentences each.

* What is the fundamental difference between zero-sum and non-zero-sum games, according to the text?

* How does the author suggest we should view interactions between individuals or groups to understand history and evolution?

* Explain the concept of 'reciprocal altruism' as presented in the text, and give an example.

* Why does the text argue that hunter-gatherer societies do not necessarily lack social complexity?

* How does the text connect population density to economic development?

* What does the author mean when they state that "farming was no great conceptual break with traditional subsistence patterns?”

* What are some ways that the text suggests that chiefs maintain their power in chiefdom societies?

* According to the text, how does writing help overcome the trust barrier?

* Explain the relationship between entropy and the growth of structure.

* How did the industrial revolution intertwine the processing of matter and energy with information?

Quiz Answer Key

* In zero-sum games, the fortunes of the players are inversely related; if one player gains, the other loses. In non-zero-sum games, it's possible for all players to benefit, or at least not lose, simultaneously.

* The author suggests that we should view all interactions through the lens of game theory, particularly focusing on whether they are zero-sum or non-zero-sum. This perspective helps explain the direction of both human history and organic evolution.

* Reciprocal altruism involves individuals providing benefits to others with the expectation of receiving similar benefits in return. This is often seen in hunter-gatherer societies, where surplus food might be shared with the expectation of reciprocation later.

* Hunter-gatherer societies, while appearing simple, possess complex knowledge of their environment and the skills necessary for survival. Differences in social complexity are more often driven by differing environmental conditions rather than a lack of intelligence.

* Higher population density facilitates more frequent interactions and exchange between individuals, leading to increased specialisation, trade, and thus increased economic development as costs of interaction are reduced.

* The text explains that farming arose gradually through the intensification of hunter-gatherer plant cultivation practices, rather than being a complete break with the past, which saw people working harder to get food from a fixed area.

* Chiefs maintain power through co-opting religious authority, controlling access to important resources, and promoting the idea that they have special access to the divine. In doing so, they use the concept of mana, not monopolizing it, but using it to flow down through a hierachy.

* Writing helps overcome the trust barrier by providing a record of agreements and transactions. It allows for more precise and permanent documentation of loans, contracts, and laws.

* The text explains that while entropy (disorder) increases universally, life creates local order and structure by consuming energy and resources, effectively pushing entropy aside in that specific locality.

* The industrial revolution created technologies, like the locomotive, that combined the processing of energy with the processing of information. The locomotive, through its feedback loops, used information about its own state to regulate its use of energy.

Essay Questions

Consider these questions carefully, drawing on the text for evidence in your arguments.

* How does the concept of non-zero-sum interactions explain the overall trajectory of human history, as presented in the text?

* Discuss the role of technology in driving social complexity, using examples from different periods discussed in the book.

* Critically analyse the argument that the advent of agriculture was a revolutionary step, versus an evolutionary development, as put forward in the text.

* How does the text address the problem of 'cheating' or 'parasitism' in societies, and what solutions does it suggest for maintaining the benefits of non-zero-sum interactions?

* Explore the role of religion and ideology in shaping social structures, especially in the context of chiefdoms and states, based on the concepts put forth by the author.

Glossary of Key Terms

Non-zero-sum Game: A situation where multiple participants can achieve mutual benefit or where one or more can avoid a loss. Outcomes are not a win-lose scenario, meaning there can be multiple winners and losers.

Zero-sum Game: A situation where one participant's gain is equal to another's loss. Outcomes are always win-lose, with one winner and one loser.

Reciprocal Altruism: The practice of acting to benefit others with the expectation of receiving benefits in return in the future. It is often seen in situations where repeated interactions are likely.

Social Complexity: The degree of differentiation and specialization within a society’s organisation, which is measured by factors like social hierarchies, economic specialization, and political structures.

Cultural Evolution: The process of change in societies and cultures, which can be driven by technological innovations, shifts in social organization, or changes in values and beliefs, often in a way that parallels organic evolution.

Carrying Capacity: The maximum population that an environment can sustain without degradation to its resources.

Proto-agricultural: Refers to societies that cultivate plants, but have not yet domesticated them. They can therefore be seen as on a path toward agriculture.

Chiefdom: A level of social organization characterized by centralized political leadership, often with hereditary chiefs who possess substantial power, but who often must work with a council of elders and whose authority is not unlimited.

State: A complex form of social organization with a centralized government that controls a defined territory and population. States are often characterized by formal institutions, laws, and a monopoly on the legitimate use of force.

Mana: A concept in some Polynesian cultures which refers to a spiritual force or power that can be inherited or acquired. It can be associated with leadership or skill.

Meme: An idea, behaviour, or style that spreads from person to person within a culture. Memes are used here to explain how ideas can influence societal structures.

Entropy: A measure of disorder or randomness in a system. The second law of thermodynamics states that entropy in a closed system tends to increase over time, leading to an overall move toward disorder.
