    Bidirectional causality of hostile media effects in political polarization3 questions

    1. Causal ordering of following politicians on social media, campaign emotions, and hostile media perceptions

    2. Durability and mechanisms of the 2016 election-driven polarization in perceived media bias

    3. Generalizing the friendly media phenomenon–hostile media effect (FMP–HME) reinforcement cycle across issues, political systems, and media environments

    Whether negative news bias is driven by supply or demand3 questions

    1. Does risk-averse demand drive the negative slant of news? Testing the McCluskey–Swinnen–Vandemoortele bad-news mechanism and its interaction with supply-side framing

    2. Sources of individual-level variation in negativity biases in psychophysiological reactions to news

    3. Do audiences reward sensational news? The unresolved causal drivers of social-media engagement with online news articles across platforms and countries

    Scale differences of echo chamber effects in cross-platform measurements2 questions

    1. Causal attribution of echo chambers on social media: recommender algorithms versus user-driven selection

    2. Causal mechanisms and cross-context generality of echo-platform fragmentation in the social media ecosystem

    Dispute over replication on whether corrective information triggers backfire effect4 questions

    1. Worldview-Motivated Resistance to Misinformation Corrections: Boundary Conditions, Mechanisms, and Genuine Belief Change Versus Strategic Expression

    2. When do corrections of political misperceptions succeed, fail, or backfire? Open boundary conditions, mechanisms, and durability after the backfire-effect debate

    3. Boundary Conditions of the Backfire Effect: When Do Factual Corrections Strengthen Political Misperceptions, and How Durable Are Corrected Beliefs?

    4. When and why do corrections backfire? Boundary conditions and mechanisms of the misinformation backfire effect

    Law of decay of media framing effects over time3 questions

    1. The duration of news framing effects: what governs their persistence and decay over time?

    2. Temporal dynamics of news framing effects: decay curves, accumulation, and recency in repetitive and competitive framing, and their psychological mechanisms

    3. The decay function of persuasion effects from mass political communication: how fast mass-communication persuasion fades, why, and how it varies across contexts

    Whether generative AI news labeling can change trust without changing discernment ability3 questions

    1. External validity and boundary conditions of the implied truth effect: does partial fact-check labeling increase belief in and spread of untagged misinformation in naturalistic social media environments?

    2. Implied-Truth Side Effects of Provenance Labels on AI-Generated Images: Generalization, Mechanisms, Tolerable Error Rates, and Design Trade-Offs

    3. Durable skill or dependency: which AI-dialogue pedagogies build lasting unassisted misinformation-detection ability, for whom, and how far the dependency effect generalizes

    Accuracy gains and counter-effects of fact-checking labels4 questions

    1. Boundary conditions of the tainted truth effect: which factors determine when retrospective misinformation warnings correct false political information versus taint accurate information

    2. Generalization and moderators of the implied truth effect: does selective fact-check labeling of misinformation backfire outside the laboratory?

    3. External validity and evidence-based design of entity-referenced fact-checking labels for online misinformation

    4. Durability and External Generalizability of Partisan Fact-Checkers' Corrective Effects on Political Misinformation

    Short-term increase and long-term narrowing of content diversity by algorithmic recommendations2 questions

    1. Single-user escape from collaborative-filtering echo chambers: algorithmic (im)possibility and robustness of diversity contraction in recommender feedback loops

    2. Filter Bubbles and Homogenization in Recommender Ecosystems with Strategic Content Producers and Competing Platforms

    Whether false news propagation is mainly driven by bots or a few highly active users2 questions

    1. Generalizing bot-versus-human reactions to deceptive and trusted news sources: longer timescales, infrequent users, and non-Twitter platforms

    2. Bot-driven amplification of social media content: generality across news classes, elections, and platforms, and the feasibility of platform-scale mitigation

    Causal distinction between agenda-setting effects and audience self-selection2 questions

    1. Causal identification of partisan news effects on vote choice: separating activation, conversion, and reinforcement from selective exposure

    2. Intermedia influence versus shared exogenous forcing: causal identification of Granger-type lead-lag links in large-scale network agenda-setting analyses
