This document discusses research on the impact of cultural diversity on trust development in virtual collaboration. It reviews prior studies that have found a lack of granularity in analyzing how cultural factors like individualism vs. collectivism influence trust between individuals from different cultures collaborating virtually. The researcher proposes to investigate this issue by studying real-world virtual collaborative projects between cultures like Brazil, the US, and UK. Hypotheses are presented that perceptions of similarity and trust will differ for individuals from collectivist versus individualist cultures. The methodology will involve measuring relevant constructs while controlling for dispositional trust and other variables.
