Since 2019 the German Research Foundation (DFG) has had a binding code of good scientific practice. Its first guideline obliges researchers alle Ergebnisse konsequent selbst anzuzweifeln, to consistently doubt all their own results. They must einen kritischen Diskurs in der wissenschaftlichen Gemeinschaft zuzulassen und zu fördern, allow and promote critical discourse in the scientific community, and keep strikte Ehrlichkeit, strict honesty, about their own contributions and those of others.
