Joober R, Schmitz N, Annable L, et al. Publication bias: what are the challenges and can they be overcome?. Editorial. Journal of Psychiatry & Neuroscience 2012;37(3):149-152
There is evidence suggesting that publication bias - withholding negative results from publication - is increasing. Psychology and psychiatry are among the disciplines in which this increase is highest. This bias may seriously distort the literature and lead to misguided research. Researchers' and editors' ethical duty should lead them to publish both positive and negative outcomes in an equitable manner. All journals should make a concerted effort to promote publication of high-quality negative studies.
