This paper explores how a particular form of regulation—prior ethical review of research—developed over time in a specific context, testing the claims of standard explanations for such change against more recent theoretical approaches to institutional changes, which emphasize the role of gradual change. To makes its case, this paper draws on archival and interview material focusing on the research ethics review system in the UK National Health Service. Key insights center on the minimal role scandals play in shaping changes in (...) this regulatory setting and how these depend upon the absence of a single coherent profession associated with biomedical research.

Experimental design is one aspect of a scientific method. A well-designed, properly conducted experiment aims to control variables in order to isolate and manipulate causal effects and thereby maximize internal validity, support causal inferences, and guarantee reliable results. Traditionally employed in the natural sciences, experimental design has become an important part of research in the social and behavioral sciences. Experimental methods are also endorsed as the most reliable guides to policy effectiveness. Through a discussion of some of the central concepts (...) associated with experimental design, including controlled variation and randomization, this chapter will provide a summary of key ethical issues that tend to arise in experimental contexts. In addition, by exploring assumptions about the nature of causation and by analyzing features of causal relationships, systems, and inferences in social contexts, this chapter will summarize the ways in which experimental design can undermine the integrity of not only social and behavioral research but policies implemented on the basis of such research.
