This study presents a novel examination of changes in attributions about individuals via information obtained from online sources within the context of hiring decisions. An experiment had 127 participants examine dossiers collected about a job applicant, in some conditions containing either positively or negatively valenced information about the applicant, obtained from the Internet. Results indicated online information significantly increases attributional certainty and positively valenced online information led to more favorable impressions of the applicant's perceived fit and employability. Surprisingly, results also violate assumptions of the increased magnitude of attributions due to negative information. Findings are discussed with respect to uncertainty reduction strategies, the negativity effect of online information, and implications for job seekers and employers.Key words: online information, attributional certainty, uncertainty reduction, hiring decision, information seeking, social media. doi:10.1111/jcc4.12072Given the growing prominence and ubiquity of access to and information on the Internet, one area of interest to computer-mediated communication (CMC) scholars is how information found online is used to form impressions of another person. Significant research has explored the process of online impression formation, including how individuals virtually signal real-world attributes (Ellison, Hancock, & Toma, 2012) and how cues generated by others or computer systems themselves are integrated into interpersonal attributions (Tong, Van Der Heide, Langwell, & Walther, 2008). Although research has enhanced our understanding of what and how impressions are formed with online information, we know relatively little about the certainty of those impressions.Unfortunately, CMC theories have been hard-pressed to conceptualize the cognitive aspect of interpersonal attributions (Lee, 2001). Previously, Walther et al. (2011), noted new phenomenon may be effectively conceptualized by applying older concepts to help frame them in a way that can be * Accepted by previous editor Maria Bakardjieva
