When a clean scent soothes the soul: Developing a positive attitude toward sharing service space with strangers

In the context of sharing services, this research examines how ambient scent can improve the perception of the presence of other sharers. Four experiments conducted in real conditions (open-plan workspaces, car-sharing services, rail-stations, and library) show that the diffusion of a clean scent promotes positive attitudes toward sharing space with others. Three alternative explanations are assessed: 1) perceived cleanliness of the space; 2) other users' behaviors; and 3) user's mood. The results indicate that throughout the four experiments, the effect of scents is mediated only by the positive mood induced by the scent. Co-written with N. Fleck-Dousteyssier & J. Grobert.
