ABSTRACT
The main bulk of this chapter is about drawing a picture of the complexities surrounding the workings of interventions. It looks into a different set of issues: implementation, nomological machines, and causal cakes. They all revolve around the possibilities of reproducibility- how to hedge our bets that an intervention will work. The chapter discusses translation of research into practice, under-determination, and fidelity. Principles that represents a generalized research-to-practice method are, Providing verbal self-prompting cues or questions to guide each subprocess in writing, Teaching well-honed schema for paragraph structure. The thesis of under-determination is general epistemology and it basically centers on confirmation of theory. The best-known version of the thesis belongs to Willard Van Orman Quine, states that under-determination permeates our entire conceptual and scientific systems. Fidelity is a demand for faithfulness. A little detour is required to clear the connection between evidence hierarchies and fidelity, the constellation generally called as EBP orthodoxy.
