The aim of this work is to relate discussions of ideology and science within the Radical Science movement of the 1960s-1980s with present conversations on the integration of biology, psychology, and education. The argument is that an ideological analysis yields useful direction with respect to how a learning science might develop and how we might appeal to our best aspirations while avoiding our worst. The ideology of "how" in the title refers to beliefs about research strategies: In an ideology of "how," the aim is discovery and there is an appreciation of complexity. This stands in opposition to an ideology of "what," which focuses on diagnosis and categorization.
