Why Default Nudges Work: Identifying Cognitive Mechanism with fMRI , Junichi Chikazoe; Kohei Kawaguchi; Kanji Suzuki; Kosuke Uetake; Yasutora Watanabe; Katsunori Yamada , 2025年9月1日
概要：<p>Default nudges are widely used and effective, but their mechanisms remain unclear. We test whether ease, endowment, or endorsement effects drive choices. In an online randomized experiment, the endowment channel emerges as the principal driver. We then use a novel fMRI approach that constructs brain activity maps of cognitions and uses them to trace their variation in each cognition during decision-making. This approach validates treatments by confirming they elicit the intended cognitions and uses them as instruments to identify the causal effect of cognition on choice. Results show that endowment drives default nudge effectiveness, suggesting policy designs should leverage it.</p>

Misperception and Accountability in Polarized Societies , Shuhei Kitamura; Ryo Takahashi; Katsunori Yamada , 2025年6月23日
概要：<p>Elections are a primary mechanism through which citizens can hold politicians accountable for misconduct. However, whether voters actually punish corruption at the ballot box remains an open question, as electoral decisions often involve strategic considerations, including beliefs about how others think and behave. To better understand how such strategic considerations operate in this context, we conducted a pre-registered information intervention during a major political corruption scandal in Japan. The treatment provided information about the prevailing social norm—specifically, the perceived social intolerance of the scandal. The treatment increased turnout and support for a challenger, particularly among swing voters who initially believed that others were intolerant of corruption. Among party loyalists with more lenient prior beliefs, the same information backfired, increasing support for the incumbent. The turnout effect among swing voters was sizable—approximately six percentage points—comparable in magnitude to benchmark mobilization interventions involving personalized contact or social pressure. To account for these patterns, we develop a simple model that incorporates mechanisms—notably *moral reinforcement* and *identity reinforcement*—that generate predictions consistent with the observed heterogeneity in responses. By highlighting how perceptions of prevailing norms shape voter behavior in the presence of strategic considerations, this study contributes to a broader understanding of how democratic institutions can remain resilient in the face of political misconduct.</p>
