the ramifications of technological innovations in communication with publications such as "Forecasting Telephone and Communication Flows." He studied the rise of electronic media, noting that print media was becoming more expensive per word published, while the opposite was true for electronic media. In his 1983 publication "Tracking the flow of information science", he made a series of predictions that came to accurately describe 21st century communication: growing quickly and increasingly electronic, with people experiencing information overload and fragmented streams of information. Pool was reunited with his former mentors Roger Hurwitz and Hirshue Inose to co-author the work A Census of Japan and the US. This would become one of his last forays into the literary world. He once again defined demand toward a global information society. De Sola Pool was the chair and founder of the MIT political science department. He was often pulled away from MIT to advise the United States and other governments on various matters. In 1965, he wrote "The Kaiser, the Tsar, and the Computer," an essay about a computer-simulated international crisis. Later, his interest in quantitative analysis and communications would contribute to computer models to study human behavior. The idea of freedom in all forms was extremely important to Pool. As a young man, Pool was a devout Trotskyite, though he quickly became disillusioned with this form of politics after seeing people's ideals used to take away the freedom for which they had initially fought. Simulmatics Corporation De Sola Pool was one of the leaders of the Simulmatics Corporation, a data science firm which used algorithms to target voters and consumers. Jill Lepore wrote extensively about the Simulmatics Corporation in her 2020 book If, Then: How the Simulmatics Corporation Invented the Future. Controversies Pool's work with the Simulmatics Corporation included Department of Defense contracts to predict counter-insurgencies in Vietnam; he also was involved in Simulmatics' efforts to predict where race riots would occur in the United States. Daniel Ellsberg would later say of Pool, "I thought of him as the most corrupt social scientist I had ever met, without question." Much of the work Pool led for Simulmatics in Vietnam was also of very low quality; one of his collaborators, a PhD in psychology, believed that Pool did not know what a null hypothesis was, saying, "He didn't know why he couldn't conclude that TV was having no effect if he couldn’t measure it."
