Joint Optimization of Uncorrelated Outcomes: Part 6 of 6 Posts on Evaluation, Complex Behavior, and Themes in Complexity Science

Common Introduction to all 6 Posts History and Context These blog posts are an extension of my efforts to convince evaluators to shift their focus from complex systems to specific behaviors of complex systems. We need to make this switch because there is no practical way to apply the notion of a “complex system” to … Continue reading Joint Optimization of Uncorrelated Outcomes: Part 6 of 6 Posts on Evaluation, Complex Behavior, and Themes in Complexity Science

A complexity perspective on a theory of change for long term program effects

Lately I have been spending a lot of time thinking about two subjects: 1) models (program, logic, change, etc.) and 2) complex behavior. (Not complex systems. I don’t like that subject.) It occurred to me that different models are relevant at different time scales. Most of the models one sees in the evaluation world involve … Continue reading A complexity perspective on a theory of change for long term program effects
