Publication bias can be contained through better-powered studies, enhanced research standards, and careful consideration of true and non-true relationships. [46] Better-powered studies refer to large studies that deliver definitive results or test major concepts and lead to low-bias meta-analysis.
A funnel plot is a graph designed to check for the existence of publication bias; funnel plots are commonly used in systematic reviews and meta-analyses. In the absence of publication bias, it assumes that studies with high precision will be plotted near the average, and studies with low precision will be spread evenly on both sides of the ...
Funding bias, also known as sponsorship bias, funding outcome bias, funding publication bias, and funding effect, is a tendency of a scientific study to support the interests of the study's financial sponsor. This phenomenon is recognized sufficiently that researchers undertake studies to examine bias in past published studies.
However, confirmation bias might be getting in your way, and the kicker is that you may not even know it. "With confirmation bias, we basically see what we want to see," says Dr. Craig Kain, Ph.D ...
In popular media, there is another element of publication bias: the desire to make research accessible to the public led to oversimplification and exaggeration of findings, creating unrealistic expectations and amplifying the impact of non-replications. In contrast, null results and failures to replicate tend to go unreported.
The problem of publication bias is not trivial as it is suggested that 25% of meta-analyses in the psychological sciences may have suffered from publication bias. [120] However, low power of existing tests and problems with the visual appearance of the funnel plot remain an issue, and estimates of publication bias may remain lower than what ...
Research has shown that volunteers tend to come from families with higher socioeconomic status. [8] Furthermore, another study shows that women are more probable to volunteer for studies than men. [9] Funding bias may lead to the selection of outcomes, test samples, or test procedures that favor a study's financial sponsor. [10]
The publication or nonpublication of research findings, depend on the nature and direction of the results. Although medical writers have acknowledged the problem of reporting biases for over a century, [12] it was not until the second half of the 20th century that researchers began to investigate the sources and size of the problem of reporting biases.
