This document discusses several ethical considerations for research involving human participants. It raises questions about informed consent, costs and benefits to participants, and privacy. The key principles are that participants must provide informed consent, having been told the purpose and procedures of the research, their right to not participate or withdraw, and potential benefits. Researchers must consider external codes and laws, risks to participants, and the consequences of the research for individuals and society. The Seedhouse Ethical Grid is presented as a tool to help structure ethical analysis in research.
