The commitment to ‘leave no one behind’ has been a key feature of all the discussions on the post-2015 agenda and the Sustainable Development Goals (SDGs). The idea that ‘no goal should be met unless it is met for everyone’ is well established in the rhetoric around the goals. In theory, this means ensuring that every individual achieves the full package of rights and opportunities of the SDGs. In the spirit of the SDGs, Chambers (2017) views the Reality Check Approach (RCA) as a ‘methodological revolution’ that can bring the up-to-date realities of those who are not to be left behind credibly and persuasively to policy-makers, professionals and the public. RCA values people’s perceptions, emphasizes context and relevance by exploring the “how” and “why” questions regarding choice and behaviors rather than focusing on just the outcomes. The presentation describes two studies in Indonesia on how the RCA has been used in very different contexts to embrace and understand multiple people’s realities. (a) the first study elicits perspectives, observations and experiences of people living in poverty on their household financial management; whereas (b) the second study explores perspectives and experiences of the research culture at universities in Indonesia. The two studies demonstrate the application of the RCA in different contexts and how this method distinguishes itself from other human centered approach in reaching inclusivity.
