Crowdsourcing projects that engage intrinsically motivated volunteers and are aimed at endeavors such as policy making, research, and social activism, need to understand how to create sustained engagement in their initiatives. We explore what happens when a group of homogeneous volunteers are exposed to heterogeneous beneficiaries. Previous research has presented anecdotal evidence suggesting that truck drivers have strong opinions against foreigners. However, our study finds no support for such notion, as it appears that truck drivers' view their profession as a stronger group in line with social identity theory.
