As the importance of interdisciplinary and transdisciplinary research approaches becomes more widely recognised, how can we overcome the danger that they are seen to be all that is needed for tackling complex problems? What are the limitations of these approaches? What else might be required?
My starting point is that improved understanding of, and action on, a complex societal or environmental problem usually requires a number of research questions to be addressed. Different questions require different kinds of research approaches. Let’s illustrate this by considering the following complex problem:
As effort goes into making cities more sustainable, how can we incorporate illicit drug users into a more sustainable city X?
Here I review six approaches, each through an example of a research question it is well suited to address. The approaches are interdisciplinarity, transdisciplinarity, monodisciplinarity, multidisciplinarity, systems thinking and action research. Each of these approaches encompasses a range of practices, so to keep things simple, I focus on only one practice here.
Interdisciplinarity
Practice considered: experts in two or more disciplines working together to address a research question.
Example research question: How does the illicit drug market work in city X?
Insight into this question could be produced by a combination of economists, sociologists and anthropologists, combining the economists’ interest in markets with the sociologists’ and anthropologists’ interest in the activities and behaviours of users and dealers.
Transdisciplinarity
Practice considered: disciplinary experts, along with stakeholders (those affected by the problem and those in a position to do something about the problem), work together to understand the problem and make improvements.
Example research question: Can we make illicit drug use safer in city X?
Insight into this question could be produced by a combination of:
- epidemiologists and criminologists looking, respectively, at health and criminal problems and their frequency
- illicit drug users providing lived experience of health and criminal problems and ideas for change
- social service providers and police providing insights into the practical impact of, respectively, health and criminal problems and ideas for change
- government policy makers providing an assessment of what is possible from a policy perspective.
The disciplines and stakeholders work together to define the approach/es to the problem, as well as to conduct the research and bring about improvements.
Monodisciplinarity
Practice considered: demography.
Example research question: How many illicit drug users are there in city X?
Insight into this question could be produced by demographers with specific skills in estimating hidden populations.
Multidisciplinarity
Practice considered: experts from a number of different disciplines, along with various stakeholders, each independently address a common research question, with some process at the end of the research that brings these insights together.
Example research question: What would life for illicit drug users look like in a sustainable society in city X?
A range of useful insights into this question could be produced, independently, by anthropologists, criminologists, sociologists, drug users, parents of drug users, ex-users, service providers, police, government policy makers, and non-government organisational leaders. The perspectives could come from individuals or small groups. A common multidisciplinary practice is to produce a book with a chapter from each of these perspectives. It can then be up to readers to integrate the insights in their own way. Another possible end point is to bring the contributors together to see what joint understandings they can come up with. For more on multidisciplinarity, see my i2Insights contribution In praise of multidisciplinarity.
Systems thinking
Practice considered: system dynamics mapping and modelling.
Example research question: How can the use of needles and syringes be made more sustainable?
Insight into this question could be produced by a system dynamics expert working with those who have specific insights into this question, such as researchers who have investigated needle and syringe use, illicit drug users, needle and syringe manufacturers, services that provide needles and syringes to illicit drug users, garbage collectors, government policy makers overseeing relevant policies, and police and others charged with implementing the policies. The system dynamics expert would use these inputs to map different “life cycles” of needles and syringes, looking particularly for reinforcing and balancing feedback loops. Models to look at the effects of possible changes in policy or practice among any of the involved groups could also be built.
Action research
Practice considered: researchers work with marginalised groups to empower them to find effective ways of addressing specific issues.
Example research question: How can the stigma associated with illicit drug use be reduced?
Insight into this question could be produced by illicit drug users being empowered to identify sources of stigma and develop countervailing strategies. This requires one or more researchers trusted by illicit drug users and skilled in supporting them in an empowering way to undertake their own research into stigma and ways to counteract it, as well as to implement the findings.
Conclusion
The aim of this i2Insights contribution is to demonstrate that understanding and acting on complex societal and environmental problems requires a range of research questions, with different questions suited to different research approaches. In particular, while interdisciplinarity and transdisciplinarity are important, those approaches cannot address all of the relevant research questions.
Furthermore, the research landscape would be immeasurably poorer if any of these approaches was not available. And finally, only some of the useful approaches to tackling complex societal and environmental problems are considered here. For more see my i2Insights contribution Finding expertise in research integration and implementation to tackle complex problems.
What do you think? How can we ensure that all useful approaches are recognised and maintain a healthy balance among them?
