data-contrast=\"auto\">This paper investigates whether Voting Advice Applications (VAAs), by exposing voters to a diverse set of politically relevant alternatives, can reduce affective polarization. While VAAs are primarily designed to inform electoral choices and increase political knowledge, we argue that their personalized presentation of ideologically diverse parties may also mitigate negative attitudes toward political outgroups. Drawing on a randomized field experiment conducted in 2024 in Japan, a context characterized by\u00a0a long-term\u00a0reign\u00a0of a governing party\u00a0and\u00a0a\u00a0dominant-party system, we find that exposure to a VAA significantly reduces affective polarization. Notably, the effect is strongest among voters who typically rely on valence-based evaluations rather than issue-based reasoning, i.e. supporters of the dominant Liberal Democratic Party (LDP). These findings suggest that VAAs, beyond their intended informational and educational functions, can serve as effective tools for mitigating partisan hostility by broadening\u00a0voters\u2019\u00a0perceived political choice set. However, the effect\u00a0appears to be\u00a0short-lived, fading after the election period.<\/span><\/p>\n<p><strong>\u5171\u50ac\uff1a<br \/>\n<\/strong><span data-contrast=\"auto\">\u65e9\u7a32\u7530\u5927\u5b66\u9ad8\u7b49\u7814\u7a76\u6240<\/span><span data-ccp-props=\"{&quot;134245417&quot;:false,&quot;335551550&quot;:1,&quot;335551620&quot;:1}\"><br \/>\n<\/span><span data-contrast=\"auto\">Waseda Institute for Advanced Study (WIAS)<\/span><span data-ccp-props=\"{&quot;134245417&quot;:false,&quot;335551550&quot;:1,&quot;335551620&quot;:1}\"><br \/>\n<\/span><span data-contrast=\"auto\">\u73fe\u4ee3\u653f\u6cbb\u7d4c\u6e08\u7814\u7a76\u6240\u3000\u4e16\u8ad6\u30fb\u30e1\u30c7\u30a3\u30a2\u30c7\u30fc\u30bf\u7814\u7a76\u90e8\u4f1a<br \/>\n<\/span><span data-contrast=\"auto\">Public Opinion and Media Data Research Group, WINPEC, Waseda University<\/span><\/p>\n<p><strong>Contact\uff1a<\/strong><span data-ccp-props=\"{&quot;134245417&quot;:false,&quot;335551550&quot;:1,&quot;335551620&quot;:1}\">\u00a0<\/span><span data-contrast=\"auto\">\u65e5\u91ce\u611b\u90ce\uff08\u65e9\u7a32\u7530\u5927\u5b66\uff09\u00a0<\/span><span data-contrast=\"auto\">Airo Hino\u00a0(Waseda University)<\/span><span data-contrast=\"auto\">\u00a0\u00a0<\/span><a href=\"mailto:airo@waseda.jp\"><span data-contrast=\"none\">airo@waseda.jp<\/span><\/a><span data-ccp-props=\"{&quot;134245417&quot;:false,&quot;335551550&quot;:1,&quot;335551620&quot;:1}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;134245417&quot;:false,&quot;335551550&quot;:1,&quot;335551620&quot;:1}\">\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u30ea\u30fc\u30eb\u30fb\u30ab\u30c8\u30ea\u30c3\u30af\u5927\u5b66\u306eMarta Gallina\u51c6\u6559\u6388\u3068\u30eb\u30fc\u30f4\u30a1\u30f3\u30fb\u30ab\u30c8\u30ea\u30c3\u30af\u5927\u5b66\u306eStefano Camatarri\u535a\u58eb\u3092\u304a\u8fce\u3048\u3057\u3001\u30ef\u30fc\u30af\u30b7\u30e7\u30c3\u30d7\u3092\u958b\u50ac\u3057\u307e\u3059\u3002 \u3069\u306a\u305f\u3067\u3082\u3054\u53c2\u52a0\u3044\u305f\u3060\u3051\u307e\u3059\u3002\u4e8b\u524d\u767b\u9332\u306f\u4e0d\u8981\u3067\u3059\u3002\u305c\u3072 [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":11917,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[104,105],"tags":[99,102,18,101],"class_list":["post-11920","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-other-en","category-other","tag-events-en","tag-general-en","tag-events","tag-general"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/posts\/11920","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/comments?post=11920"}],"version-history":[{"count":1,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/posts\/11920\/revisions"}],"predecessor-version":[{"id":11924,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/posts\/11920\/revisions\/11924"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/media\/11917"}],"wp:attachment":[{"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/media?parent=11920"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/categories?post=11920"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.waseda.jp\/fpse\/winpec\/wp-json\/wp\/v2\/tags?post=11920"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
