KEY FEATURES: Wide interdisciplinary applicability with step-by-step examples drawn from a number of sciences and professional fields, including defense, medicine, education, and ecology, demonstrate the powerful application of information metrics to comparative case studies. Presentation of techniques that can be used broadly allows readers to apply what they learn in settings including business, finance, health care, environmental policy, security, and other settings where consequential decisions are made under conditions of uncertainty and complexity. Clear and accessible prose illustrated by concrete and carefully explained examples makes the methods easy to understand and immediately applicable. A concise review of the exciting intellectual foundations of information theory motivates student interest by linking research with critical real-world problems, from World War II cryptography to Cold War nuclear deterrence to solving modern cyber-security and strategic challenges. Appendices available both in the book and online provide a walkthrough of Excel or Google sheets for automating simple calculations, along with sample Excel sheets (Appendix A) and an implementation of the methods in the open source language, R (Appendix B).

The Information Revolution

Information theory draws on the rich scientific and applied developments of the Information Revolution we discussed in Chapter 1. It also connects to basic concepts of probability, uncertainty, and complexity. In this chapter, we provide a deeper intellectual background for the relatively simple yet profound information analytics that we apply toward enhancing comparative case studies. We start with an overview of information theory and the conceptual groundwork for its use in comparative case study. We then introduce the information metrics and provide an intuitive review of the probability and mathematical concepts that facilitate their calculation. Finally, we highlight information theory’s multifaceted contributions and some practical benefits of our method.
