Drawing from expectancy violation theory, we investigate how entrepreneurs' language-based expressions of their political ideology influence the performance of their crowdfunding campaigns. We argue that crowdfunding funders expect campaigns to be apolitical, suggesting that entrepreneurs' expressing their political ideologies-regardless of the specific ideology-create a negative expectancy violation that decreases funding performance. As source credibility is a central boundary condition for expectancy violation theory predictions, we also suggest this relationship is mitigated by three indicators of entrepreneurial credibility: prior successful experience, media usage, and third-party endorsements. Using a sample of 19,898 Kickstarter campaigns and a randomized experiment, we find support for our theoretical predictions. Executive summary The role of political ideology has become an important topic in entrepreneurship research (e.g., Maldonado-Bautista et al., 2021; Lewis et al., 2021; Zhou, 2013). Throughout the literature, researchers have generated significant insights showing that entrepreneurs' conservatism and liberalism serve as ideological values that ultimately guide the decisions impacting their new ventures (Chin et al., 2021; Jarrodi et al., 2019). Despite these insights, the current literature informs comparatively less about how entrepreneurs' political ideologies are perceived by others and whether expressing their political ideologies is valued throughout the new venture process. The present research explores these questions by examining how entrepreneurs' expressions of political values shape their ability to attract funding for their new venture via crowdfunding. To develop our conceptual model, we draw from expectancy violations theory (i.e., a perspective that explains how individuals respond to unexpected behavior during communication; Burgoon et al., 2002) and communication research illustrating that discussing politics is seen as unprofessional in business (Gera et al., 2020; Tillman, 2022). Based on this theoretical framework, we suggest that funders in crowdfunding expect entrepreneurs' campaigns to be generally free of political expressions. As such, entrepreneurs hurt their crowdfunding performance by violating this expectation if they express their political ideology-regardless of whether they are expressing a conservative or liberal ideology. We then examine whether the expectation for entrepreneurs to be generally apolitical in their crowdfunding campaigns depends on the credibility of the entrepreneur. Expectancy violations theory suggests that individuals with greater credibility about a topic have 2 greater freedom to violate existing expectations (Burgoon et al., 2002). Following this logic, we also examine three indicators of an entrepreneur's credibility identified in previous crowdfunding research by Courtney et al. (2017) (i.e., entrepreneurial experience, entrepreneurial media usage, third-party endorsements). We contend that these indicators of entrepreneur credibility mitigate the negative influence of political expressions on crowdfunding performance. We test our model using Kickstarter campaigns based in the United States (N = 19,898) and using a randomized experiment (N = 668). Results provide general support for our predictions. Entrepreneurs diminish the amount of funds raised in their crowdfunding campaigns by approximately 9 % and 17 % for every percentage point increase in their expressions of conservatism or liberalism, respectively. The negative influence of political expressions is mitigated when the entrepreneur had more entrepreneurial experience, more media usage in their campaigns, and a third-party endorsement (i.e., Kickstarter's 'Project We Love' badge). We also found strong evidence that funders expect entrepreneurs' crowdfunding campaigns to be apolitical in our randomized experiment and that political expressions lead to perceptions of unprofessionalism among potential funders. The overall results unveil an overlooked reality: in a society in which entrepreneurs are increasingly discussing politics and intertwining it with their businesses (Carothers and O'Donohoue, 2019; Zipkin, 2018), crowdfunding funders expect entrepreneurs to be apolitical. Our study contributes to the literature in three key ways. First, we diverge from the focus on the literature suggesting entrepreneurs' political ideologies serve as values that affect their business decisions and, instead, demonstrate the importance of how entrepreneurs' political ideologies are perceived. Second, we highlight the expectation in crowdfunding that entrepreneurs should generally avoid discussing their political ideologies, but that entrepreneurs with more indications of credibility may be granted greater latitude to discuss their political values. Finally, we contribute back to expectancy violations theory by answering calls to uncover the underlying mechanisms that explain why expectancy violations evoke specific reactions among individuals in certain settings (Bur-goon, 2015) by providing evidence that norms of professionalism form the expectation of apoliticality in crowdfunding campaigns.
