In addition to a code of conduct for researchers, it is desirable to implement a code of conduct for funders of research. This is because researchers often behave unethically as a result of direct and/or indirect pressure from funders. The paper provides an expansion of the first proposal for such a code of conduct and includes several elements such as “policy relevant research should not be contracted and supervised by a client with an interest in the outcomes”, and “policy relevant (...) research should always be examined by an independent institute”.
