"The rapid spread of online misinformation poses an increasing risk to societies worldwide. To help counter this, we developed a ‘fake news game’ in which participants are actively tasked with creating a news article about a strongly politicized issue (the European refugee crisis) using misleadi ... more
"The various practices of constructive journalism have the common objective to achieve certain effects on the audience: on the micro-level, the users’ information and emotion, on the meso-level the loyalty towards a media company, and on the macro-level the progress of society. Taking a holistic d ... more
"This memo presents evidence based on a survey experiment embedded in a national survey of Ukrainians and a laboratory experiment conducted with Ukrainian university students. The findings indicate that anti-Corruption messaging that emphasizes the success of anti-Corruption campaigns (i.e., a “po ... more
"This paper is based on a qualitative study of couples living in SASA communities and secondary analysis of endline quantitative data collected as part of a cluster randomised control trial designed to evaluate the impact of the SASA! intervention. The primary trial was conducted in eight communitie ... more
"Redistribution programs in developing countries often “leak” because local officials do not implement programs as the central government intends. We study one approach to reducing leakage. In an experiment in over 550 villages, we test whether mailing cards with program information to targeted ... more
"Media campaigns can potentially reach a large audience at relatively low cost but, to our knowledge, no randomised controlled trials have assessed their effect on a health outcome in a low-income country. We aimed to assess the effect of a radio campaign addressing family behaviours on all-cause po ... more
"Does social influence exerted through role modeling of collective action impact social change in contexts that are not conducive to collective action, such as long-lasting violent conflicts? We examined this question in two field experiments in the Eastern Democratic Republic of Congo. We created t ... more
"When we hear stories of distant humanitarian crises, we often feel sympathy for victims, but may stop short of taking action to help. Past research indicates that media portrayals of distant suffering can promote helping behavior by eliciting sympathy, while those that prompt a more rational respon ... more
"Five weeks prior to the 2011 general election in Liberia, women in randomly selected villages were allocated radios and organized into groups to listen regularly to radio programs on the electoral process broadcast by the United Nations Mission in Liberia (UNMIL). The field experiment was designed ... more
"Narrative is essential for public engagement with global poverty. Stand Up Planet, a documentary about global development, was produced to evaluate the effects of a little-utilized nonfiction comedy narrative. Using a pretest–posttest experimental design, this study examines shifts in U.S. audien ... more
"How does media influence beliefs, attitudes, and behaviors? We know surprisingly little about this influence and I argue that two mechanisms account for its impact. Media provides new information that persuades individuals to accept it (individual channel), but also, media informs listeners about w ... more
"The present study (N= 1074) examined the impact of a theory-driven media intervention aimed atviolence prevention and intergroup reconciliation in Burundi. We used a novel methodology utilizing audio-based surveys to assess attitudes related to intergroup conflict and reconciliation among community ... more
"Poor-quality data about conflict events can hinder humanitarian responses and bias academic research. There is increasing recognition of the role that new information technologies can play in producing more reliable data faster. We piloted a novel data-gathering system in the Democratic Republic of ... more
"This study provides insights that can inform disaster communication management, policymaking, and theory building through a nationally representative field experiment (N = 2,015 U.S. adults) grounded in media richness theory, information and communication technologies (ICTs) succession theory, and ... more
"Can the mass media cause changes in an audience’s knowledge, attitudes and intention to practise behaviours? At BBC Media Action, we have just successfully conducted a randomised control trial (RCT) to investigate this chain of causality in a prime time health TV drama in Bangladesh." (Introducti ... more
"We use a “natural experiment” in media markets in Benin to examine the impact of community radio on government responsiveness to citizens. Contrary to prior research on the impact of mass media, in this experiment government agents do not provide greater benefits to citizens whose exposure to c ... more
"This article presents and discusses the results of an experiment in which television viewers were exposed to either a war journalism (WJ) or a peace journalism (PJ) version of two news stories, on Australian government policies towards asylum seekers and US-sponsored ‘peace talks’ between Israe ... more
"Partisan media are often blamed for polarization in newly liberalized regimes. However, there is little empirical work on the subject, and information-processing theories suggest that extreme position taking is only one possible response to opinionated news. Rather, we theorize that partisan media ... more
"Many people recognise that mass media is important in promoting public health but there have been few attempts to measure how important. An ongoing trial in Burkina Faso (ClinicalTrials.gov, NCT01517230) is an attempt to bring together the very different worlds of mass media and epidemiology: to me ... more
"We report on a field experiment and a focus group interview study that examine the impact of a media-based intervention (i.e., radio drama) aimed at promoting peaceful intergroup relations in the Eastern Democratic Republic of Congo (DRC). In Study 1, we used a priming paradigm to assess the causal ... more
