recommendations! Published in 2017 at "Psychological Methods"

DOI: 10.1037/met0000119

Abstract: Quantitative research literature is often biased because studies that fail to find a significant effect (or that demonstrate effects in an undesired or unexpected direction) are less likely to be published. This phenomenon, termed publication… read more here.
