IT consumerization has brought social media (SM) and personal mobile devices into many workplaces. This has prompted researchers to examine the benefits and risks of this trend. However, little research has examined how personal experiences with technology such as social media may affect decision making on the job. This study examines the potential impact of individuals' trusting beliefs (competence, benevolence, and integrity) regarding algorithms and social media communities (SMC) on initial trust in SM-based business analytics (BA), as well as on relative advantage over non-SM based BA. Study results suggested that the initial trust was influenced by the belief in the competency of personal algorithms as well as trust in SMC. It also indicates that increased trust in SMC influences relative advantage. Implications and suggestions for further research are discussed.
