Here we study Menlo as a case of what we call ethics governance in the making, finding that this process examines past controversies and enrols existing networks to connect the everyday practice of ethics with ethics as a form of governance. To create the Menlo Report, authors and funders relied on bricolage work with existing, available resources, which significantly shaped both the report's contents and impacts. Report authors were motivated by both forward- and backward-looking goals: enabling new data-sharing as well as addressing past controversies and their implications for the field's body of research. Authors also grappled with uncertainty about which ethical frameworks were appropriate and made the decision to classify much network data as human subjects data. Finally, the Menlo Report authors attempted to enrol multiple existing networks in governance through appeals to local research communities as well as taking steps towards federal rulemaking. The Menlo Report serves as a case study in how to study ethics governance in the making: with attention to resources, adaptation, and bricolage, and with a focus on both the uncertainties the process tries to repair, as well as the new uncertainties the process uncovers, which will become the site of future ethics work.
