The study employed the trust game paradigm and a task where participants were asked to evaluate the safety of tour guides to examine the interactive effects of name recognizability and reduplication on the perceived trustworthiness of the investee and the perceived safety of tour guides. The results revealed that in both tasks, name recognizability has an impact on individuals' perceived trustworthiness. Specifically, individuals with easily recognizable names are perceived as more trustworthy compared to those with difficult-to-recognize names. Moreover, in the task of evaluating tour guide safety in hazardous scenic areas, it was found that the reduplication feature of names influences the perceived trustworthiness of tour guides. Tour guides with non-reduplicated names receive higher safety ratings and are perceived as more trustworthy than those with reduplicated names. Although the interaction between name recognizability and reduplication is not statistically significant, simple effects analysis indicated that the impact of reduplicated names on tour guides' trustworthiness is modulated by name recognizability. When names are difficult to recognize, the effect of reduplication on trustworthiness diminishes.
