Republican governors with a particularly high charisma signaling score impacted the outcome more relative to Democratic governors in comparable conditions. Our results also suggest that one standard deviation higher charisma signaling in governor speeches could potentially have saved 5,350 lives during the study period (02/28/2020–05/14/2020). Next, in an incentivized laboratory experiment we found that politically conservative individuals are particularly prone to believe that their co-citizens will follow governor appeals to distance or stay at home when exposed to a speech that is high in charisma; these beliefs in turn drive their preference to engage in those behaviors. These results suggest that political leaders should consider additional “soft-power” levers like charisma—which can be learned—to complement policy interventions for pandemics or other public heath crises, especially with certain populations who may need a “nudge.”</p></div>","PeriodicalId":48434,"journal":{"name":"Leadership Quarterly","volume":"34 6","pages":"Article 101702"},"PeriodicalIF":7.5,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10201331/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10074229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, there is a trend towards more behavior-based research, with interaction coding as one promising method. By precisely analyzing recordings of leader–follower interactions, interaction coding helps quantify verbal and non-verbal behavioral patterns that unfold between leaders and their followers, thereby providing access to the behavioral dynamics that are at the core of leadership. Yet, analyzing leader–follower interactions is much less straightforward than it might appear. Bold claims like “objective data” and “actual behavior” frequently used in such studies tend to paint a somewhat tainted picture of the opportunities and challenges associated with interaction coding. To synthesize the existing empirical knowledge concerning the use of interaction coding in leadership research, we present the findings from a critical review of the current research landscape. This review highlights that questions related to observer inference, standards for observer agreement, and the validity of interaction coding are often not sufficiently addressed in empirical work. Drawing on these findings, we identify questionable research practices and juxtapose these with best-practice recommendations. Finally, we provide a discussion and outlook on how behavior-based methods can move the leadership field forward by facilitating theoretical advancements and deriving actionable guidance for practitioners.</p></div>","PeriodicalId":48434,"journal":{"name":"Leadership Quarterly","volume":"34 6","pages":"Article 101751"},"PeriodicalIF":7.5,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1048984323000772/pdfft?md5=1a3f6b64e43b9e11829f2856eb8a1bb0&pid=1-s2.0-S1048984323000772-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71417081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
