Publication bias
Publication bias is a type of bias that occurs in published academic research. It occurs when the outcome of an experiment or research study influences the decision whether to publish or otherwise distribute it.
Pronunciation

Etymology
The term "Publication bias" is derived from the English words "publication" and "bias". "Publication" comes from the Latin word "publicare", which means "to make public", and "bias" comes from the Greek word "epikarsios", which means "oblique".
Definition
Publication bias refers to the tendency of researchers, editors, and pharmaceutical companies to handle the reporting of experimental results that are positive (i.e., showing a significant finding) differently from results that are negative (i.e., supporting the null hypothesis) or inconclusive, leading to a misleading bias in the overall published literature.
