EXPRESS: Guardians of Trust: How Review Platforms Can Fight Fakery and Build Consumer Trust

As customers increasingly rely on online reviews for making consumption decisions, the dangers arising from misinformation and fakery have become an acute source of concern for consumers, firms, and society at large. Many online review platforms claim a role as guardians of trust in the information exchange process. Yet, little is known about the practices they can utilize to design platforms that build and safeguard consumer trust. We draw on governance and identity disclosure literatures to propose five practices that mitigate fakery and build trust in the platform: monitoring, exposure, community building, status endowment, and identity disclosure. Five studies (1) establish the individual and joint effects these practices have on platform trust, (2) identify the mediating processes by which the practices build trust, (3) verify the ecological value of the conceptual framework, (4) provide support of the salience of the practices, and (5) show how the practices build trust above-and-beyond review content-level characteristics. Interaction effects suggest that exposure, community building and status endowment obviate the need for identity disclosure in building platform trust, a finding that mitigates related privacy concerns. Collectively, our findings can improve platform design, enabling review platforms to fulfill their promise of mitigating fakery and increasing trust.
