Most recently, in "Studying Human Behavior: How Scientists Investigate Aggression and Sexuality" (2013), Longino examines five scientific approaches to human aggression and sexuality in terms of their epistemological frameworks, the types of knowledge that they produce, and their pragmatic goals. She argues that different approaches begin from and build upon different causes, each of them producing partial knowledge about the subject. As such, they cannot be reduced to a single perspective. From her perspective in social epistemology, Longino argues that scientific research will be more useful as a guide to public policy makers if the plurality of different approaches to knowledge is acknowledged. Increasing awareness of the range of perspectives to be examined can benefit policy by more thoroughly informing decisions, and also encourage caution about too quickly adopting policy positions based on a limited perspective.
