  • Do sectarian differences affect support for armed non-state actors? Evidence from survey experiments in Lebanon, Iraq, and Yemen

    Open Access•Kota Suechika, Dai Yamao•ARTICLE•Politics and Religion•2026

    Sectarian cleavages are widely seen as central to Middle Eastern conflict, and Iran-backed armed non-state actors (ANSAs)—Hezbollah, the popular mobilization units, and the Houthis—are often portrayed as sectarian militias. Yet there is little empirical evidence that public support for these actors systematically varies along sectarian lines. Drawing on original survey experiments conducted in Lebanon, Iraq, and Yemen during the 2023–2025 Gaza wa…

  • Support for Protests in Post-conflict Societies

    Open Access•Dai Yamao•ARTICLE•Humanities and Social Sciences…•2026

    This paper examines which types of protest are more likely to garner public support in fragile post-conflict states, drawing on evidence from survey experiments conducted in Iraq in 2023. While a substantial body of research has examined protest under democratic and authoritarian regimes, less attention has been paid to how citizens evaluate different forms of protest in post-conflict contexts characterized by weak state capacity, fragmented auth…

  • Why anti-LGBTQIA+ law is supported in Iraq? An evidence from conjoint analysis

    Open Access•Shingo Hamanaka, Dai Yamao•ARTICLE•British Journal of Middle Eastern…•2026

    On April 27, 2024, Iraq’s National Assembly, established after the country’s 2003 transition to democracy, passed a controversial anti-LGBTQIA+ law. This development raises critical questions about public support for such policies in a democratic system expected to protect sexual minority rights. Why has intolerance toward LGBTQIA+ individuals increased alongside democratization? Is this trend linked to the political system itself or independent …

  • Heroes inciting political unrest

    Open Access•Dai Yamao•ARTICLE•Cogent Social Sciences•2025

    This article endeavors to examine the extent to which individuals perceive the Popular Mobilization Units (PMUs), a prominent former militia umbrella organization in Iraq and a typical example of armed semi-non-state actors, as a primary catalyst for political turmoil and its associated issues, drawing insights from the outcomes of a list experiment conducted within the framework of our original survey. Based on the results of the list experiment…

  • How do Islamists represent nation state? A comparative studies of the Islamic state and Taliban based on a quantitative text analysis

    Open Access•Yutaka Takaoka, Dai Yamao•ARTICLE•Cogent Social Sciences•2025

    This article compares the evolving perceptions of modern states and nationalism held by two Islamist organizations—the Islamic State (IS) and the Taliban—both of which aim to establish an Islamic state. Using a quantitative text analysis, the study examines the factors shaping non-state actors’ views of the state and how these views change over time. A corpus consisting of the Taliban’s journal al-Sumud and IS’s journal al-Nabaʾ was compiled, and…

  • Do Elections Promote Conflict? A Quantitative Text Analysis of Postwar Iraqi News Coverage

    Open Access•Dai Yamao•ARTICLE•The Developing Economies•2025

    This article seeks to investigate whether conflict‐motivating coverage in newspapers increases during the election period, employing a quantitative text analysis of several major newspapers in postwar Iraq. In the aftermath of the war in Iraq, the exclusion or inclusion of the former Baathist regime emerged as one of the most contentious issues in elections. Consequently, this study analyzes how the exclusion or inclusion of the former regime was…

  • Measuring the evolution of Arab States’ perceptions of the Iranian threat

    Dai Yamao, Kota Suechika•ARTICLE•British Journal of Middle Eastern…•2024

    After the Arab Uprisings, inter-state relations in the Middle East became polarized between the two camps of the Saudi-led Gulf Cooperation Council (GCC) and Iran and its allies, which strengthened the threat perception of Iran among Arab states. This study aims to empirically elucidate the changes in the perception of threats against Iran among Arab states through a quantitative text analysis of major state media in 10 Arab states. Through this …

  • Political mobilization and its impact on voter turnout

    Open Access•Dai Yamao, Shingo Hamanaka•ARTICLE•Asian Journal of Comparative…•2021•References: 22

    This article clarifies how political mobilization affects voter turnout in a post-conflict society by analyzing the Iraqi case using survey data. Voter turnout was high in post-war Iraq. However, the voter turnout in the fourth election, held in May 2018, declined by 20 percentage points from the previous one in 2014, mainly because of widespread political distrust due to corruption among political elites and their embezzlement of public funds, n…
