  • 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
