“Tracking the Leakage of Development Goods Using iBeacon Technology”
with Jenny Hamilton and Muthoni Nganga

The leakage of development goods—defined broadly as deviations from program guidelines about who should receive the items in question—is a major challenge for governments and a preoccupation of development practitioners and academic researchers. Although commonly reported and lamented, leakage is challenging to quantify and trace. We address this evidentiary blind spot by piloting the use of iBeacon technology to track how village elders distribute solar lanterns within off-grid communities in western Kenya. We provide evidence on the efficacy of the technology for detecting the lanterns and tracking their movement. We analyze why some households received lanterns and others did not, finding compelling and unexpected patterns. Nearly all lanterns remained within the participating communities, contrary to expert predictions. Although we find some evidence for the salience of social connections between village elders and lantern recipients, most households with a lantern met the priority distribution criterion. We find also evidence of lantern distribution to households with needs along dimensions beyond our designated criterion. Our findings run against common depictions of local African elites as predatory actors and suggest the need to rethink the common equation of “leakage” with malfeasance. They also underline the potential for political economy research leveraging this technology at scale.

“Urbanization and Interethnic Relations in Africa”

I leverage data from urban and rural Kenya to learn about the impact of urbanization on interethnic relations, complementing prior work that focuses on urban populations alone or that characterizes interethnic relations via a narrower set of survey-based outcome measures. While I find evidence that both urban and rural participants expect outgroup members to harbor ethnic biases, I find no evidence for differential altruism or cooperation across coethnics and non-coethnics, either among urban or rural participants—including when coding those participants using a measure that captures the continuous nature of urban-rural connections. I do, however, find evidence of cross-group bias along a dimension of interethnic relations rooted in like/dislike, captured via a different measurement strategy. Moreover, I find that this bias differs across urban and rural domains, with stronger preferences for coethnics among rural participants. The results point to a potential weakening of cross-group bias due to urbanization.

“The Backstory Matters: Reducing Anti-Herder Bias Among Displaced Farmers in Benue State, Nigeria”
with Adejumo Oluwabunmi, Efobi Uchenna, and Jiyoung Kim

Do farmers displaced by farmer-herder conflicts in Nigeria update their views about herders when they are informed about the circumstances outside of the herders’ control that forced them to leave their traditional grazing areas and encroach on the farmers’ lands? We address this question by randomizing the exposure of nearly 2,000 displaced farmers to a video depicting the devastating impact of climate change on the herders’ traditional grazing lands. Farmers exposed to the video are more compassionate about the herders’ plight, report greater comfort with a range of hypothetical social interactions with herders, reduce their negative stereotypes about herders, become more trusting of herders, and voice greater support for policies that might improve herders’ livelihoods. Our findings have important implications for improving social cohesion following climate-related conflict and displacement. They also underscore a broader phenomenon: that victims’ responses to harm can be shaped by a deeper appreciation of the circumstances that drove the behavior of the perpetrators.

“Can a Distraction Task Reveal Hidden Bias in Economics Games?”
with Jennifer A. Hamilton and Chad Hazlett

Social scientists widely use behavioral economics games such as the Dictator Game (DG) to measure inter-group biases, including ethnic discrimination. Yet, in numerous contexts where ethnicity is thought to be extremely salient, the DG has failed to detect any evidence of ethnic bias. One explanation is that economics games like the DG permit participants to alter their behavior to fit social norms that discourage ethnic bias or discrimination, thereby masking biases that are nevertheless relevant to real-world and political behavior. We test this explanation by experimentally reducing self-monitoring through a cognitive load manipulation. In a within-subjects design, 555 Kikuyu and Luo adults in Nairobi, Kenya played multiple DG rounds under varying levels of cognitive load induced by a spatial delayed recall task (SDRT). If self-regulation explains the lack of ethnic bias in the DG and is meaningfully impaired through this demanding distraction task, we anticipate stronger evidence of ethnic bias under cognitive load. Despite evidence that our manipulation increased cognitive load, we find no evidence of differential ethnic bias across DGs conducted at varying cognitive loads. These results suggest that participants are not suppressing ethnic bias through effortful self-control. We argue instead that the intergroup bias in this context may arise from dislike, fear, or threat perception, which are not well measured by the DG.  

“Broken Pipeline: Higher Education and the Production of African Development Researchers”
with Annet Adong

Any meaningful effort to address the underrepresentation of African voices in development research must begin with the teaching, mentorship, and inspiration of young scholars that happens in African universities. This is where the pipeline of African researchers is created and where scholars are equipped with the training required to produce research that can shape policy debates and guide decision making. In this paper, we draw on original survey and interview data to characterize the challenges faced by African universities in producing development researchers. We discuss the factors that cause so many promising scholars at the undergraduate level to choose not to continue their training at the graduate level. We assess the quality of the training that is available for the students who do elect to continue their studies. And we discuss the attractiveness of, obstacles to, and implications of acquiring graduate training outside of Africa. 

“Modulating Our Better Angels: A Brain Stimulation Study of Cognitive Processes Underlying Effortful Control of Racism”
with Chad Hazlett, Marco Iacobini, and Akila Kadambi

Efforts that many people make to avoid showing biases toward other ethnic or racial groups, while not always sufficient or effective, are critically important to how we treat each other and to the functioning of our diverse society. While this “effort to control racism” has long been studied in social psychology, we know little about  its neurocognitive underpinnings. Our previous work shows that two prefrontal areas of the brain modulate generosity towards others, with the DLPFC particularly operative in controlling racist impulses. We posit they may also control racism. Using multiple assessments of bias and Transcranial Magnetic Stimulation (TMS) we aim to show  that transient inhibition of these areas may reduce the ability to override implicit biases, enhancing racially biased behavior. These results will contribute to an early understanding of how to modulate functional mechanisms to overcome racial bias.

“Ethnic Identification and Ethnic Deception: Experimental Evidence from Uganda, South Africa, and the United States”
with Adam S. Harris, Daniel L. Nielson, Lily Medina, Clara Bicalho, Michael G. Findley, Jeremy M. Weinstein, James Habyarimana, and Macartan Humphreys

Social scientists widely believe that ethnicity has special ability to demarcate political cleavages. First, people can generally discern others’ ethnicity by sight or brief interaction. And second, people cannot easily change their ethnicity. While scholars tend to agree that both of these traits are disproportionately associated with ethnicity, the conditions under which ethnic group memberships are more or less visible and sticky have not yet been systematically investigated. This article formalizes ethnic identifiability, operationalizes its key concepts, and tests its causes through 59,000 observations in lab-in-the-field experiments in Uganda, South Africa, and the United States. The results indicate significant differences across and within country contexts in both the discernability and the mutability of ethnic identity. Critically, we find that people can successfully pass as other ethnicities at moderate to very high rates, depending on country and ethnicity. The findings suggest substantial grounds for treating a bedrock assumption in social science with greater conceptual nuance and more empirical rigor.
