Abstract
Although there is usually agreement about the ethical principles that should govern research on children, there may be little agreement on how those principles should be interpreted into research procedures in some instances. Empirical research on ethical issues that arise in research on children can often elucidate ways to improve on existing research practices and ways to resolve debates about best practices. Following in the success of evidence-based medicine, evidence-based ethical problem solving in human research can enable investigators to avoid such poor alternatives as doing nothing, endlessly debating, or acting on the basis of hunch or time-honored but dubious research practices. A variety of approaches to evidence-based ethical problem solving are illustrated in this article.
