Building Bridges in the Digital Age: How online platforms foster trust during a crisis
研究了中国新冠疫情期间互助平台如何通过可验证性、可定位性和可保护性三种数字功能建立制度信任，进而促进情感信任，并扩展至更广泛的社会信任。
Trust has long been studied as a key factor in explaining why an actor is willing to risk vulnerability to others amid uncertainty and potential risks. While various forms and antecedents of trust have been explored, its development between strangers during periods of heightened uncertainty remains under-examined. To address this gap, we conducted a qualitative study of a mutual aid platform launched during the Covid-19 pandemic in China. Our process model identifies three core digital affordances—verifiability, targetability, and protectability—that foster institution-based trust among platform users. Additionally, our findings suggest that institution-based trust acts as a critical precursor to emotional trust. This indicates that digital platforms not only activate impersonal, system-based trust as previously theorized, but also enhance interpersonal and emotional trust. Moreover, we show that positive platform interactions during times of crisis can lead users to extend their trust to a broader range of societal members and social activities beyond platform interactions. Lastly, our study highlights that while uncertainty is essential for trust to emerge, trust building on platforms also depends on the platform provider’s established reputation, which aids trust transfer and facilitates the initial exploration of the platform.
