Complexity and evaluation

Here is the abstract of my latest article on complexity and evaluation, which you can find here:

This article offers a critical review of the way in which some scholars have taken up the complexity sciences in evaluation scholarship. I argue that there is a tendency either to over claim or under-claim their importance because scholars are not always careful about which of the manifestations of the complexity sciences they are appealing to, nor do they demonstrate how they understand them in social terms. The effect is to render ‘complexity’ just another volitional tool in the evaluator’s toolbox subsumed under the dominant understanding of evaluation, as a logical, rational activity based on systems thinking and design. As an alternative I argue for a radical interpretation of the complexity sciences, which understands human interaction as always complex and emergent. The interweaving of intentions in human activity will always bring about outcomes that no one has intended including in the activity of evaluation itself.


Complex, but not quite complex enough

During the last 10-15 years there have been repeated appeals to the complexity sciences to inform evaluative practice in books and journals about evaluation. This partly reflects the increased ambition of many social development and health programmes which are configured with multiple objectives and outcomes and the perceived inadequacy of linear approaches to evaluating them. It could also be understood as a further evolution of the methods vs theories debate  which has led to theory-based approaches becoming much more widely taken up in the evaluative practice. It is now very hard to avoid using a ‘theory of change’ both in programme development and evaluation. What kind of theory informs a theory of change, however?

Although the discussion over paradigms has clearly not gone away, the turn to the complexity sciences as a resource domain for evaluative insight could be seen as another development in producing richer theories better to understand, and make judgements about, complex reality. However, some evaluators are understandably nervous about the challenge of what they perceive as being the more radical implications of assuming that non-linear interactions in social life may be the norm, rather than the exception. In a variety of ways they try to subsume them under traditional evaluative orthodoxies, which is just as one might expect any thought collective to respond. Continue reading
