Asking better questions to build better models Sharon Dawes
Some policy questions Should we eradicate polio? How can schools help third graders become good readers? What kinds of public investments lead to urban vitality? What is the optimal approach to immigration? How does health insurance coverage affect health care costs? Can a ban on large sugary drinks reduce obesity and diabetes? Does public posting of sanitary inspections lead to cleaner restaurants?...
All models are wrong, some are useful. Box, 1979
Why models are wrong Complexity Boundaries Dynamics Data Time
Boundaries Organizations, jurisdictions, sectors Groups, individuals and their interests Existing policies and laws Contextual factors Processes Practices Geography Behaviors What goes in the model, what is left out, and why and how do the choices matter?
Dynamics Feedback structure of URBAN1, Ghaffarzadegan, et al.
The “best available data” (BAD) is inherently flawed Knowledge problems Meaning Explicitness Codifiability Embeddedness Dynamics Data problems Accuracy Completeness Bias Timeliness Availability...
Time Problem definition Goal setting Policy formulation Strategy formulation Design Development Deployment Implementation Operations Performance assessment Evaluation
Policy modeling over time Problem definition Goal setting Policy formulation Strategy formulation Design Development Deployment Implementation Operations Performance assessment Evaluation Understanding the problem and the options Exploring alternative approaches Understanding the policy system Evaluating and interpreting policy impacts
Stakeholders bring Different knowledge and points of view Different goals and preferences Different capabilities and authority to act Different cultures (national, organizational, professional) Different amounts and kinds of power and autonomy Different levels of confidence and trust Different amounts of tolerance for risk
An example: eradication of polio with thanks to Dr. Kimberly Thompson & colleagues

Some suggestions Build relationships with policy makers and policy advisors Treat models as learning objects to be improved by interaction with the people who own the policy problem. Adopt techniques that engage stakeholders group model building, participatory design, value-sensitive design Learn and speak the language of practice Custom-make presentations for policy makers and managers Consider multiple methods to understand context and complexity case studies, test beds, evaluation studies Update, iterate, adjust, repeat
Many questions, many answers, better models Policy makers Other analysts Policy stakeholders Policy modelers The big policy question ÷ Elements of complexity Boundary questions Data challenges Dynamic interactions Time considerations X Multiple iterations Plain language = Insights, better understanding of policy options and effects
