New special issue in the /Journal of Social Computing/, “Technology Ethics in Action: Critical and Interdisciplinary Perspectives” *Summary* This special issue interrogates the discourses and impacts of “tech ethics.” As many institutions embrace tech ethics in response to concerns about digital technology, it is necessary to consider the impacts, limits, and opportunities of these initiatives. The articles in this issue analyze tech ethics as a practical and political endeavor, rather than a primarily philosophical one. What's happened as "tech ethics" has become a widespread discourse? What are the limits of tech ethics initiatives? How can we develop better paths forward? We hope that this issue will be a useful resource for research, teaching, advocacy, and more.
