I have never been very comfortable with the concept of root causes. I do see the need to go below the surface and not just look at the ‘symptoms’. Yet, it seems to me that the concept of root causes – one problem causing one or a number of symptoms – is at odds with the idea of complex systems, where patterns emerge as a result of a number of different interconnected and interdependent elements and structures.

The idea or root causes is linked to a linear cause-effect kind of thinking. This often plays out as follows: development agents going into a country, observing an undesirable pattern or symptom, doing some analysis to find a root cause, fixing it, and assuming the symptom will disappear – a linear causal chain is assumed from the root cause to the symptom. This is also the reason why many projects use results chains – chains of boxes and arrows indicating steps in a causal chain from the root cause to the symptom.

The problem with this type of thinking is that it does not reflect how the world really works. Still, this is how development generally approaches complex problems. Complexity thinking offers a different way of thinking about intractable or ‘messy’ issues such as getting stronger and more inclusive economies. One concept in particular seems helpful to replace the linear causal logic from root causes to symptoms: the concept of modulators. Continue reading →
