  Establishing trust between developers working at distant sites facilitates
team collaboration in distributed software development. While previous research
has focused on how to build and spread trust in absence of direct, face-to-face
communication, it has overlooked the effects of the propensity to trust, i.e.,
the trait of personality representing the individual disposition to perceive
the others as trustworthy. In this study, we present a preliminary,
quantitative analysis on how the propensity to trust affects the success of
collaborations in a distributed project, where the success is represented by
pull requests whose code changes and contributions are successfully merged into
the project's repository.
