File drawer effect
If null and inconclusive results remain unpublished, the visible literature begins to systematically overestimate the strength and stability of the effect.
Registration of studies against bias
The more studies that are registered before a result is published, the more difficult it is for the literature to quietly lose negative and null findings in the file drawer.
Funnel plot and displacement features
A funnel plot does not provide a definitive verdict, but it does allow one to notice asymmetries that may indicate publication bias or other systematic distortions in the corpus.
