What are the ethical considerations linked to publication bias? Should you always publish your results in open sources, irrespective of the conclusions and the methodological quality of the study? Is it dierent in dierent research areas? For example, if you conducted a twin study and found that there is a strong genetic predisposition to depression, but later realized that there might have been sampling bias in your study, should the results be published? Should you openly warn the readers about the potential sampling bias?
