Previous studies have forwarded a self-fulfilling prophecy explanation for how algorithmic beliefs may shape affective and relational outcomes of online dating (Hu & Rui, 2023; Sharabi, 2021). The current work examined this self-fulfilling prophecy explanation by investigating relevant online dating correlates of algorithmic beliefs. Secondary analyses were conducted on data from a nationally representative sample of U.S. adults (N = 6034) with model comparison procedures. Collectively, results showed that, among currently single relationship-seeking online daters, algorithmic beliefs were negatively related to online dating disappointment; However, findings for online dating excitement were mixed. Additionally, among past online daters, algorithmic beliefs were positively related to being in a relationship with someone they met in online dating. Consistencies and differences between the current findings and previous findings were discussed to offer theoretical and practical implications.
