    • Fallacies of Experimental Evaluation
      Whatcausessomething to happen has nothing to do with the number of timesit happens (Sayer, 1992, p.165)

    • Why Realist Evaluation
      Departure: Social problems are embedded in a stratified reality
      Rationale: Not repeating programs as a craft, but evaluating program theories as epistemic devices
      Generative causality: Knowing what works for whom in what circumstances (resources and reasoning)
      Realistic: Don’t study the program, study the inner workings

    • Another Wicked Problem: Multiple Explanations
      Making sense of it:
      Theory adjudication
      weeding out rival explanations, with focus on improvement
      Configurational
      application in practice
      Middle-range
      transferability; patterns of repeat victimization
      Provisional
      tested but not proven; soft system and wicked problems
