information bias

Concern about the introduction of information bias by scanners (B.7).

Examples of information bias are prevalent in medical diagnosis.

Hidden profiles interact with the shared information bias to produce poor decisions.

Information bias could have arisen due to mistakes in coding, especially for medications.

The shared information bias may also develop during group discussion in response to the interpersonal and psychological needs of individual group members.

Information bias occurs due to people's curiosity and confusion of goals when trying to choose a course of action.

Information bias is also referred to as observational bias and misclassification.

Information bias is bias arising from systematic error in the assessment of a variable.

In epidemiology, Information bias refers to bias arising from measurement error.

Information bias may refer to:

JEMs may also reduce differential information bias that might occur when evaluating exposure for individuals from medical records in which their jobs are apparent.

Information bias (epidemiology)

Information bias is a type of cognitive bias, and involves e.g. distorted evaluation of information.

The occurrence of information biases may not be independent of the occurrence of selection biases.

Subjects in experiments concerning medical diagnostic problems show an information bias in which they seek information that is unnecessary in deciding the course of treatment.

Some epidemiologists prefer to think of confounding separately from common categorizations of bias since, unlike selection and information bias, confounding stems from real causal effects.

Among the biases which can negatively impact the veracity of this type of study are selection bias and misclassification or information bias as a result of the retrospective aspect.

An example of information bias is believing that the more information that can be acquired to make a decision, the better, even if that extra information is irrelevant for the decision.

The hypothesis of an association between coronary heart disease and poor oral health was not part of the design or conduct of the original or follow up studies, which would further decrease possible information bias.

Moreover, when individuals make decisions as part of a group, there is a tendency to exhibit a bias towards discussing shared information (i.e., shared information bias), as opposed to unshared information.

People with lower SES tend to gain information from TV, but the information bias to the entertainment than accurate information which make people lower SES learn poorly.

Information bias (epidemiology), bias arising in a clinical study because of misclassification of the level of exposure to the agent or factor being assessed and/or misclassification of the disease or other outcome itself.

Behavioral economists attribute the imperfections in financial markets to a combination of cognitive biases such as overconfidence, overreaction, representative bias, information bias, and various other predictable human errors in reasoning and information processing.

In support of the observations by Postmes et al. (2001), Stewart and Stasser (1998) have asserted that the shared information bias is strongest for group members working on ambiguous, judgment-oriented tasks because their goal is to reach consensual agreement than to distinguish a correct solution.

Evidence of scholarly work on this subject can be traced to the 1980s, when an article authored by Barbara J. Kostrewski and Charles Oppenheim and published in the Journal of information science, discussed issues relating to the field including confidentiality, information biases, and quality control.
