Social intervention in Curaçao: Using behavioral science technologies for social and economic development, 1969-1971

This article examines how the American psychologist David McClelland advocated a quasi-colonial interventionist view to social science, shaped by his understanding of scientific progress, economic development, and social change. In the 1960s, he saw real-world experiments as a means both to test his theories and to generate knowledge efficiently and quickly-all with the ultimate aim of improving the human condition. While his primary focus was knowledge production rather than social transformation, his dual roles as professor and consultant carried an interventionist dimension, grounded in the belief that psychological measuring instruments could serve as tools for psychological training. By reconstructing this stance and the interstitial space McClelland created between academia and consultancy, I aim to show that his drive to intervene-exemplified by his company's work in Curaçao-stemmed less from a pre-scientific conviction than from a distinctive mode of scientific practice.
