This article discusses Internet research ethics, which promises to become an ever-more robust and significant field within information ethics, on the one hand, and research ethics more broadly, on the other. As new venues emerge for human–human and human–machine interaction, it seems certain that new ethical conundrums will emerge. But the overall history of Internet research ethics includes at least some convergence on key values and rights, while at the same time preserving important local differences with regard to approaches to ethical decision making and implementation of basic rights and principles – even across East–West divides. This trajectory suggests not the certainty of finding resolutions to every ethical problem that comes along, but rather the sense of finding such resolutions in the face of new difficulties, with sufficient frequency and success to encourage further efforts to do so.
