[19] Studies have shown that volunteers tend to come from a higher social standing than from a lower socio-economic background. [20]
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.
In science research, experimenter bias occurs when experimenter expectancies regarding study results bias the research outcome. [122] Examples of experimenter bias include conscious or unconscious influences on subject behavior including creation of demand characteristics that influence subjects, and altered or selective recording of ...
Academic bias has also been argued as a problem due to discrimination against conservative students.
