I have been toying with an idea about thinking of “fidelity” in terms of “attractors” as they are cast in complex adaptive systems (CAS). I have yet to convince myself that this idea makes any sense in either a formal or a metaphorical sense. I am even less convinced that even if it does make sense, that it is at all useful in helping to do better evaluation. I’m open to suggestions, so please whack away.
I got interested in this topic because now that “Evaluation in the Face of Uncertainty” has been published, I have been pondering how to advance some of the ideas I set out in that book. The “fidelity/attractor” idea is one of the trails I have been sniffing.
What is the problem?
I think there are two big ideas floating around in our field that are tugging at each other. The first is the notion of “fidelity”, i.e. the notion that for a program to be successful as it moves into different settings, it must maintain a core set of characteristics. (Let’s assume we know what those are.) The second idea is that things are never the same as they move through space and time. We know from research on innovation adoption that “reinvention” is common. And certainly, all our recent talk about developmental evaluation, systems, complexity, and so on speak to the belief that programs are in a constant state of flux. I’m groping for a way to bring “fidelity” and “change” under a single conceptual umbrella.
