Coded Bias exposes prejudices and threats to civil liberty in facial recognition algorithms and artificial intelligence.
Understanding research bias allows readers to critically and independently review the scientific literature and avoid treatments which are suboptimal or potentially harmful. A thorough understanding of bias and how it affects study results is essential for the practice of evidence-based medicine.

Information bias, also called measurement bias, arises when key study variables are inaccurately measured or classified. Information bias occurs during the data collectionstep and is common in research studies that involve self-reporting and retrospective data collection. It can also result from poor interviewing techniques or differing levels of r...
Interviewer biasstems from the person conducting the research study. It can result from the way they ask questions or react to responses, but also from any aspect of their identity, such as their sex, ethnicity, social class, or perceived attractiveness. Interviewer bias distorts responses, especially when the characteristics relate in some way to ...
Publication bias occurs when the decision to publish research findings is based on their nature or the direction of their results. Studies reporting results that are perceived as positive,statistically significant, or favoring the study hypotheses are more likely to be published due to publication bias. Publication bias is related todata dredging (...
Researcher bias occurs when the researcher’s beliefs or expectations influence the research design or data collection process. Researcher bias can be deliberate (such as claiming that an intervention worked even if it didn’t) or unconscious (such as letting personal feelings, stereotypes, or assumptions influence research questions). The unconsciou...
Response bias is a general term used to describe a number of different situations where respondents tend to provide inaccurate or false answers to self-report questions, such as those asked on surveys or in structured interviews. This happens because when people are asked a question (e.g., during aninterview), they integrate multiple sources of inf...
Selection biasis a general term describing situations where bias is introduced into the research from factors affecting the study population. Common types of selection bias are: 1. Sampling or ascertainment bias 2. Attrition bias 3. Self-selection (or volunteer) bias 4. Survivorship bias 5. Nonresponse bias 6. Undercoverage bias
Cognitive biasrefers to a set of predictable (i.e., nonrandom) errors in thinking that arise from our limited ability to process information objectively. Rather, our judgment is influenced by our values, memories, and other personal traits. These create “ mental shortcuts” that help us process information intuitively and decide faster. However, cog...
While very difficult to eliminate entirely, research bias can be mitigated through proper study design and implementation. Here are some tips to keep in mind as you get started. 1. Clearly explain in yourmethodology section how your research designwill help you meet the research objectives and why this is the most appropriate research design. 2. In...
Dec 23, 2021 · In terms of research, “bias is any trend or deviation from the truth in data collection, data analysis, interpretation and publication which can cause false conclusions” (Simundic, 2013, p. 12). From this definition it can be determined that bias may occur in any part of the research process.
Jan 17, 2021 · Bias, perhaps best described as ‘any process at any stage of inference which tends to produce results or conclusions that differ systematically from the truth,’ can pollute the entire spectrum of research, including its design, analysis, interpretation and reporting. 1 It can taint entire bodies of research as much as it can individual ...
Nov 8, 2021 · In academic research, bias refers to a type of systematic error that can distort measurements and/or affect investigations and their results.[1] It is important to distinguish a systematic error, such as bias, from that of random error.
Research bias, often unavoidable, is a systematic error that can creep into any stage of the research process, skewing our understanding and interpretation of findings. From data collection to analysis, interpretation, and even publication, bias can distort the truth we seek to capture and communicate in our research.
