What really happened when the world's two greatest superpowers went head to head during the Cold War? We Now Know is a major reappraisal of the struggle for political and ideological supremacy between the United States and the Soviet Union from 1945 to the Cuban Missile Crisis of 1962.

Kenneth Waltz's Theory of International Politics created a "scientific revolution" in international relations, starting two major debates. In the 1980s it defined the controversy between the neorealists, who believed that competition between states was inevitable, and the neoliberals, who believed that states could cooperate with each other. As the debate wound down with the end of the Cold War in the 1990s, a second more fundamental debate began.

In his 1936 book The General Theory of Employment, Interest and Money, Keynes argued that traditional economics has misunderstood the causes of unemployment. Employment is not determined by the price of labor; it is directly linked to demand in the economy. Keynes believed market economies are by nature unstable and so require government intervention. Spurred on by the social catastrophe of the Great Depression of the 1930s, Keynes set out to change the way the world thinks about economics.

US psychologist Abraham Maslow's 1943 essay "A Theory of Human Motivation" established his idea of humanistic psychology as a "third force" in the field. He outlined a new approach to understanding the mind, saying humans are motivated by their need to satisfy a series of hierarchical needs, starting with the most essential first. He thought it important for the advancement of psychology to identify, group, and rank them in terms of priority.

Michael R. Gottfredson and Travis Hirschi's 1990 work, A General Theory of Crime, assessed contemporary work in criminology, while also introducing a new, comprehensive theory of crime. At the time, researchers tended to focus on environmental factors that led to crime, not on the criminals themselves. Additionally, crime researchers came from different disciplines and inclined towards thinking about crime only from their particular perspective. This meant ideas about what caused crime, and how to prevent it, were often in conflict.
