Psychology, Scientific Control, Chicago, and the Impact of European émigrés

After a long hiatus, psychology and economics today are back in conversation with each other: active research programs in behavioral economics, neuro-economics, and the economics of happiness bespeak a thriving cross-disciplinary discussion. Yet for most of the twentieth century, economists distanced themselves from psychology; when they spoke of science, they referred, in the first instance, to the physical sciences, then perhaps to the biological sciences. A hundred years ago, however, American intellectuals viewed psychology as a progressive science and economics as traditionalist – mired in the antiquated notions of laissez-faire and individualism. A social science that assumed individuals knew their preferences, directed their actions toward fulfilling them in a rational manner, and in the process engaged others in dispassionate exchange, was clearly not speaking to the issues of the modern world. The death of progressivism in the wake of WW I only reinforced the rise of psychology: good intentions weren’t enough, motives were suspect, rational individuals went mad in the midst of conflict and turmoil, complex emotions ruled. Careful psychological analysis could, however, enable society to gain some degree of control over the fundamental irrationality of human action.
