Disabled and Romani passengers face similar levels of discrimination but different levels of open hostility in the sharing economy.

This multimethod project investigates discrimination against members of two populous minority groups in the European Union: the Roma (numbering 6 million) and the disabled (numbering 100 million) on a leading Hungarian carpooling platform. In a field experiment, 1005 ride requests were sent to drivers, with passenger group membership (control, disabled, Roma) manipulated between participants. Widespread discrimination against both groups was apparent in significantly lower approval rates for disabled (56%) and Roma passengers (52%) relative to control (70%). Mechanisms driving anti-disabled and anti-Roma discrimination were probed using an experimental manipulation, natural language processing analysis of driver-passenger interactions, and an online survey (N = 398). Individuating information in the form of reviews did not mitigate unequal treatment, thus providing evidence against statistical (stereotype-based) discrimination. Militating against taste-based (attitudinal) discrimination, respondents reported negative attitudes toward Roma passengers but positive attitudes toward disabled passengers. Moreover, despite equivalent approval rates, disabled passengers were more likely to receive a response from drivers and received more polite responses than Roma passengers did. Overall, the observed patterns are most readily explained by intergroup emotions: Contempt toward Roma passengers likely engenders both passive and active harm, whereas pity toward disabled passengers likely engenders passive harm and active facilitation.
