Attracting highly skilled IT talent has become a priority and an immense burden for government organizations—especially when they have other—higher paying—employment opportunities. We set out to explore why IT professionals choose a government job to make an impact on society. We aim at disentangling the effects of different types of motives, such as extrinsic, intrinsic, and other-oriented motivational forces on the decision to accept a challenging government IT job. We use self-determination theory (SDT) to analyze publicly available statements of former private sector IT professionals reporting their reason for joining 18F. Our study is one of the first attempts to use SDT as a comprehensive framework for conducting qualitative research into work motivation in the public sector. We shed light on the conceptual and empirical distinctiveness of motives, behaviors, and perceptions of prosocial impact, which are often lumped together in the public service motivation (PSM) literature. We contribute novel empirical evidence to a nascent stream of research that uses SDT to disentangle the intrinsic, prosocial, and purely extrinsic motives that drive individuals' decisions to join public-sector organizations
