John H. Miller, Scott E. Page.
Complex Adaptive Systems: an introduction to computational models of social life.
Princeton University Press. 2007

This book provides the first clear, comprehensive, and accessible account of complex adaptive social systems, by two of the field’s leading authorities. Such systems—whether political parties, stock markets, or ant colonies—present some of the most intriguing theoretical and practical challenges confronting the social sciences. Engagingly written, and balancing technical detail with intuitive explanations, Complex Adaptive Systems focuses on the key tools and ideas that have emerged in the field since the mid-1990s, as well as the techniques needed to investigate such systems. It provides a detailed introduction to concepts such as emergence, self-organized criticality, automata, networks, diversity, adaptation, and feedback. It also demonstrates how complex adaptive systems can be explored using methods ranging from mathematics to computational models of adaptive agents.

John Miller and Scott Page show how to combine ideas from economics, political science, biology, physics, and computer science to illuminate topics in organization, adaptation, decentralization, and robustness. They also demonstrate how the usual extremes used in modeling can be fruitfully transcended, allowing the investigation of systems composed of moderate numbers of interacting and thoughtful, but not perfect, agents across a variety of important domains. Finally, they outline a twenty-first-century research agenda for the social sciences based on these ideas.

The Difference: how the power of diversity creates better groups, firms, schools, and societies.
Princeton University Press. 2007

In this landmark book, Scott Page redefines the way we understand ourselves in relation to each other. The Difference is about how we think in groups, about how our collective wisdom exceeds the sum of its parts. Why can teams of people find better solutions than brilliant individuals working alone? And why are the best group decisions and predictions those that draw upon the very qualities that make each of us unique? The answers lie in diversity—not what we look like outside, but what we look like within, our distinct tools and abilities.

The Difference reveals that progress and innovation may depend less on lone thinkers with enormous IQs than on diverse people working together and capitalizing on their individuality. Page shows how groups that display a range of perspectives outperform groups of like-minded experts. Diversity yields superior outcomes, and Page proves it using his own cutting-edge research. Moving beyond the politics that cloud standard debates about diversity, he explains why difference beats out homogeneity, whether you’re talking about citizens in a democracy or scientists in the laboratory. He examines practical ways to apply diversity’s logic to a host of problems, and along the way offers fascinating and surprising examples, from the redesign of the Chicago “El” to the truth about where we store our ketchup.

Page changes the way we understand diversity—how to harness its untapped potential, how to understand and avoid its traps, and how we can leverage our differences for the benefit of all.
