Olsen’s position takes as its point of departure the growing schism between action research and the use of randomised control trials (RCTs) and specifically argues for a realist alternative approach as one way to underpin and operationalise development research. In the following short essay, I set out the terms of the underpinning warrant for the argument, and in the conclusion suggest additional ways to elaborate.
