This study analyzed the effects of an individual's propensity to trust on the successful collaboration in distributed software projects. The researchers collected data on 218 pull requests from one open source project involving 6 integrators. They used integrators' email language and the Big 5 personality model's agreeableness trait as a proxy for propensity to trust. Logistic regression found integrators with high propensity to trust were 34% more likely to accept pull requests, even after controlling for other factors. However, the study had limitations including focusing on one project and using agreeableness as the sole measure of propensity to trust. Further research on more projects is needed.
