Policies are selected in order to bring about some desired social outcome or to prevent an undesired one. Medical treatments are applied in order to cure a disease or to ameliorate its effects. In each case an intervention is performed in the belief that this intervention will causally interact with a larger system in such …
System tendencies?
A central theme of many of the posts here is the contingency, heterogeneity, and path dependency of social processes. I used the metaphor of a "constrained random walk" in an earlier posting to characterize many social processes. This figure is intended to stand in contrast to the idea of an inevitable development towards an optimum …
What social science can do
Quite a few postings here emphasize the limits of social science knowledge. Prediction of the behavior of large social wholes is difficult to impossible. There are few strong regularities among social phenomena. Social entities and processes are heterogeneous, plastic, and path-dependent. So the question arises: what can the social sciences do that takes them beyond …
Social surprises
The near meltdown of the US financial system this week came as a surprise to most of us -- experts, legislators, and citizens alike. That isn't to say that the components of the disaster were unknown -- the subprime crisis, the earlier financial undoings of Fannie Mae and Bear Stearns this summer, and the sudden …
What is social scientific knowledge?
The social and behavioral sciences endeavor to describe, explain, and interpret the range of the social and behavioral facts that surround us. To refer to this body of findings as “science” is to claim a set of epistemic values about the nature of the methods of inquiry and evaluation that are used to arrive at …
Realism for the social sciences?
Scientific realism is the idea that scientific theories provide descriptions of the world that are approximately true. This view implies a correspondence theory of truth -- the idea that the world is separate from the concepts that we use to describe it. And it implies some sort of theory of scientific rationality -- a theory …
Social science and social problems
Several of the interviews that I’ve conducted in recent weeks have agreed on an important point: that the social sciences ought to be directed towards addressing important social problems, and that the research agenda for social science ought to be influenced or shaped by the constituencies in society who are most affected by these social …
Agent-based modeling as social explanation
Logical positivism favored a theory of scientific explanation that focused on subsumption under general laws. We explain an outcome by identifying one or more general laws, a set of boundary conditions, and a derivation of the outcome from these statements. A second and competing theory of scientific explanation can be called "causal realism." On this …

What does rational choice theory explain?
Rational choice theory could be advanced as a pure set of axioms embodying a formal representation of individual choice under circumstances of uncertainty and strategic interaction. Decision theory incorporates the idea of maximizing utility under circumstances of uncertainty and risk. The basic rule is that the decision-maker could collect information about the utility and probability …
