• The Credibility Revolution 2.0 shifts focus from design to full‐process transparency. • Code sharing is a key component of the ongoing “Credibility Revolution 2.0.” • I argue code sharing benefits individual researchers and the scientific community • I offer concrete steps for journals, funders and institutions to promote code sharing This opinion piece argues that code sharing is a key yet underutilized component of research transparency and the ongoing “Credibility Revolution 2.0.” It outlines the benefits of providing replication code for both individual researchers and the broader scientific community, and explains why alternative methods of documenting the details of the research process fall short. The opinion piece concludes with concrete recommendations for how different groups in the scientific community can help make code sharing the norm in empirical research.
