研究者必須盡可能地做到不傷害，包括把預期利益最大化，風險最小化。在履行不傷害的準則時，研究者必須評估研究過程中之風險及預期利益（包括受試者所渴望獲得的利益、研究過程中所預期產生的知識發展，以及研究成果在科學上的價值）的性質及範圍。

1. The ethical obligation to do good and avoid causing harm.
2. Persons are treated in an ethical manner not only by respecting their decisions and protecting them from harm, but also by making efforts to secure their well-being. Such treatment falls under the principle of beneficence. The term “beneficence” is often understood to cover acts of kindness or charity that go beyond strict obligation. In this document, beneficence is understood in a stronger sense, as an obligation. Two general rules have been formulated as complementary expressions of beneficent actions in this sense: (1) do not harm and (2) maximize possible benefits and minimize possible harms.
