The Irredeemability of the Past: Determinants of Reconciliation and Revenge in Post-Conflict Settings
In the aftermath of violent conflict, identifying former enemy collaborators versus innocent bystanders forced to flee violence is extremely difficult. In many post-conflict settings, internally displaced persons (IDPs) risk becoming stigmatized and face difficulties reintegrating into society. This work considers the role of moral disapproval and future social value in processes of post-conflict reconciliation with stigmatized IDPs. We run experiments embedded within a large-N face-to-face survey across three areas of Iraq (n=4,500) that are experiencing the return of stigmatized IDPs, many of whom are suspected of having collaborated with the Islamic State in Iraq and Syria (ISIS). We find that immutable factors related to a stigmatized IDP’s past behavior, namely the severity of a transgression and the volition behind it, are the strongest predictors of both reconciliation and revenge. Transitional justice mechanisms signalling the IDP’s present and future redemption have little to no impact. Analyses employing cognitive and emotional statistical mediators further demonstrate that past behavior shapes justice intuitions because it simultaneously activates a past-oriented moral condemnation and a future-oriented heuristic assessment of the value and risks of associating with the stigmatized individual. This orientation towards past behavior is consistent irrespective of major individual differences including trust in the involved institutions, ISIS victimization, and ethnic identity. These findings highlight the mounting challenges involved in transitional justice in the aftermath of violent conflict and suggests that fact-finding missions are key to re-integration of the millions of displaced persons IDPs currently in Iraq and elsewhere.

Baghdad, Al Anbar, and Najaf, Iraq, 2020-2023
Civil conflicts gravely damage the state’s legitimacy. Institutions are rendered incapable of providing security; social trust among its citizenry diminishes; and non-state actors step in to fill the vacuum of power. Following conflict, the state needs to re-establish itself as the legitimate arbiter of processes aimed at bringing former rebel collaborators to justice. Unless it carefully considers subnational variation in the drivers of forgiveness and reconciliation with rebel collaborators, the state may generate new grievances among some communities, increasing the chances of rebel recidivism or the outbreak of new conflict. This project develops and tests a novel framework integrating political science theories of legitimacy with psychological theories of forgiveness, feelings of (in)justice, and desire for revenge. To test this framework, we conduct in-depth interviews, hold focus groups and implement three large-scale surveys with embedded experiments among citizens and local leaders (N=4,800) in Iraq, a country that has endured a series of civil conflicts culminating in the recent confrontation with the Islamic State in Iraq and Syria (ISIS). This project employs innovative tools to identify both the subnational drivers of violent resentment towards the state and the drivers of reconciliation. It provides policymakers with the information necessary to design successful strategies for reconciliation, re-establishment of state legitimacy, and lasting peace.

Gothenburg, Sweden, To Punish or To Pardon, 2020-2022
Thousands of European citizens who travelled to Iraq and Syria to join the Islamic State (IS) now seek repatriation and reintegration into their home communities. This project seeks to understand the conditions under which Europeans will accept the return of compatriot IS collaborators into their communities. How does variation in the social identity of an IS collaborator (e.g. gender, age) or the type of collaboration (e.g. combat, marriage to a fighter, or employment in a civilian job) affect prospects for reintegration? Can state-imposed punishments or rehabilitative measures contribute to reconciliation? Or should these transgressions result in the loss of citizenship for these Europeans, as some policymakers are promoting? Moreover, once the state decides to impose a punishment, how do injustice gaps between what a person perceives as appropriate and what the state decides affect desires for retribution and state legitimacy?
This project develops a theoretical framework integrating political theories of state legitimacy with psychological theories of (in)justice, retribution, and forgiveness. To test this framework, we will run Facebook surveys in Sweden with embedded conjoint experiments. The study includes a sample of 1500 Swedish-speaking and 1000 Arabic-speaking inhabitants of Sweden in order to allow for examination of variations across older versus newer residents of Europe. In this age of international terrorism, this project provides policymakers with information to help create safe, secure, and inclusive societies, with broader implications for others accused of criminal behaviors and the legitimacy of the state.

Legal Pluralism and Fragmented Sovereignty: A Survey Experiment in Iraq, 2018-2019
Where state and non-state legal orders coexist within the same territory, what factors determine individual preferences among alternative providers of justice and order? Are some people more prone to favor legal pluralism versus believing in the legitimacy of a single legal system for all cases? Or does it depend on factors that are specific to the case? Systematic, empirical research on this question is lacking, particularly in the Middle East. Through a series of vignette experiments conducted among Sunni Arabs in the Iraqi city of Mosul, where the population has long been exposed to numerous justice systems (state, tribal, and Islamic), this research demonstrates which types of people are most likely to prefer which type of legal systems and provides some insights as to why. The results fill a gap in the extant research by causally identifying factors across dispute cases that drive selection of one type of system over another. Disputes within the family are generally directed towards customary legal orders, though participants prefer that more costly cases go to the state legal system. Sectarian outgroup dynamics are not as impactful as one might expect. Observational data analyses demonstrate that Moslawis face a difficult choice between a highly corrupt, but highly powerful state system and less enforceable, seemingly less corrupt non-state orders. Women and respondents with lower monthly incomes tend to prefer non-state forums.
Six post-survey focus groups reveal that rather than challenging the state, non-state orders play a unique role in local level governance. Customary systems offer citizens a more restorative route for dispute resolution that focuses on the maintenance of social relationships among community members. This may explain why women tend to shun the state system, which is expected by research in other post-conflict contexts to better protect their rights. As the poor may not be able to afford the costs associated with lawyers and state court fees, their preference for customary systems may result from structural inequalities. These findings contribute to ongoing debates over how much prevailing models of peace and state-building should be reformed from championing state-centered approaches to encouraging complementarity between customary forms of dispute resolution and state ones. This research has important implications for efforts by governments and development practitioners seeking to maintain peace and order in areas where state legitimacy and sovereignty are limited.

Reintegration of Rebel Collaborators: Survey Experiments in Mosul, 2017-2018.
What are the conditions under which civilians will accept neighbors who collaborated with an insurgent group back into their community after conflict? Does punishment of rebel collaborators facilitate post-conflict reintegration? What are the effects of the identity of a rebel collaborator (e.g. gender, age, ethnicity) and the nature of her collaboration with the insurgent group (e.g. marriage to a fighter, military service, or logistical support) on the form of punishment (e.g. imprisonment, reparations, de-radicalization programs, and community service) desired by their community members to promote forgiveness and reconciliation? We address these questions through a conjoint survey experiment conducted in the Iraqi city of Mosul, which was controlled and governed by the Islamic State (IS) for more than three years. We find that people who collaborated to greater extents or are perceived as having done so willingly will be less likely to be accepted back into the community compared to those who collaborated to lesser extents or were coerced to collaborate. The findings of this research have important implications for the stabilization and reconstruction of war-torn societies around the world. The survey was administered in Mosul in March-April 2018 by an experienced and respected Iraqi research firm (N=1,450). The pre-analysis plan for this work here. With Mara Revkin.
