Sharing of research code would greatly benefit neuroscience, but this practice is hampered by a collective action problem. Since the development of the internet, conditional pledge platforms (e.g., Kickstarter) have increasingly been used to solve globally-dispersed collective action problems (Hallam, 2016). However, this strategy has yet to be implemented within academia. In this brief paper, we introduce a general purpose conditional pledge platform for the research community: Project Free Our Knowledge. We highlight a new conditional pledge campaign that was initiated at Brainhack 2021 and aims to motivate a critical mass of neuroscientists to share their research code. Crucially, this commitment activates only when a user-defined threshold of support is reached. We conclude by sharing our vision for how the research community could use collective action campaigns to create a sustained, evidence-based movement for social change in academia.
