Widely varying contexts, rapidly accumulating changes to our environments and technological progress make Interaction Design for International Development (IDID) a challenging endeavour where it is essential to have a body of scientifically acceptable principles as disciplinary commons. Scientific principles can be formulated as theorisations, including rules, guidelines, models, methods, taxonomies, frameworks or theories which can guide research design, processes, development and improvement of interaction design practices and technologies. Many Global South countries have vast reserves of precious metals, which could be used to generate much needed funding for socio-economic development if the environmental impact and beneficiation are managed sustainably. Beneficiation in the mining industry is a process whereby impurities are removed to abstract a higher value product. Missing out on the beneficiation opportunities in the mining industry is a compelling problem for many Global South countries. Similarly, researchers and specifically Global South researchers miss out on the benefits of theorising as a beneficiation mechanism in research. Acknowledging the historic isolation and marginalisation of researchers from the Global South and the inhibition of alternatives to mainstream knowledge production. This paper focuses on a different aspect, the potential of theorisation to mobilise and amplify the voices of developing country researchers specifically by considering the potential of synthesising and abstracting findings beyond isolated insights. This question is investigated by a systematic literature review of papers published from 2020 to 2024 in the Computer-Human Interaction Conference. While the number of papers mentioning theory has increased since 2020, most findings report insights as the contribution; few papers abstracting theorisations like criteria, principles, guidelines or models, which would make the research knowledge more accessible and transferable. While acknowledging the challenges to theorisation this could imply an underused opportunity for value addition through theorisation.
