In the digital age, periods of political crisis are critical moments when misinformation intensifies and weakens public reasoning. For this reason, understanding the role of individuals’ susceptibility to misinformation within the context of political behavior is vital for designing effective counter-disinformation strategies. This study aims to how political communication during a crisis window shapes citizens’ accuracy judgments and online sharing intentions, using the Misinformation Susceptibility Test (MIST) as a measurement tool and situating effects within individual cognitive dispositions.

In the mixed-methods research design, first, the discourses of ruling and opposition actors during the crisis window (pre–core–post) will be analyzed according to discourse analysis principles. Then, selected discourses will be presented to participants to measure perceived truthfulness and sharing intentions. Cognitive and emotional tendencies, as well as attitudes related to media and politics, will be considered in this process.

The expected contribution of this study is to provide context-sensitive and causal evidence on how political discourse circulating during times of crisis intersects with citizens' truth-evaluation processes and online behavioral intentions. The findings aim to clarify the micro-dynamics between political communication and individual evaluative processes and to inform policy and educational initiatives that seek to strengthen the quality of the democratic public sphere.
