Publication bias refers to the tendency for researchers, reviewers, and publishers to favor studies with statistically significant results, positive findings, or significant effects, while rejecting or ignoring studies with null, nonsignificant, or inconclusive results. This may lead to an overestimation of the effect size or significance level of a certain intervention, treatment, or phenomenon, and may result in biased conclusions, recommendations, or policies. Confirmation bias refers to the tendency for individuals to seek or interpret information in a way that confirms their preexisting beliefs, expectations, or hypotheses, while ignoring or rejecting evidence that contradicts them. Overreaching bias and enterprise bias are not commonly used terms to describe this phenomenon.
