When research participants go missing otherwise become non-responsive, it can be a big deal to a research project. It can undermine the integrity of the project or otherwise make results impossible. For some project designs (eg device-based clinical trials) it should be a matter of participants’ safety. Does your institution provide guidance on how to ethically and responsibly such participants? Hopefully it doesn’t suggest using a Goldberg machine.
