bias

(BY-us) In a scientific research study or clinical trial, a flaw in the study design or the method of collecting or interpreting information. Biases can lead to incorrect conclusions about what the study or clinical trial showed.

A systematic difference between an estimate of and the true value of a parameter.

A prejudice based on experiences or a particular worldview. Any media channel, publishing format, organization, or person is biased by how and why they were created and their own experiences the current set of social standards in which they exist other markets they operate in the need for self preservation how they interface with the world around them their capital, knowledge, status, or technological advantages and limitations Search engines aim to be relevant to users, but they also need to be profitable. Since search engines sell commercial ads some of the largest search engines may bias their organic search results toward informational (ie: non-commercial) websites. Some search engines are also biased toward information which has been published online for a great deal of time and is heavily cited. Search personalization biases our search results based on our own media consumption and searching habits. Large news organizations tend to aim for widely acceptable neutrality rather than objectivity. Some of the most popular individual web authors / publishers tend to be quite biased in nature. Rather than bias hurting one's exposure The known / learned bias of a specific author may make their news more appealing than news from an organization that aimed to seem arbitrarily neutral. I believe biased channels most likely typically have a larger readership than unbiased channels. Most people prefer to subscribe to media which matches their own biases worldview. If more people read what you write and passionately agree with it then they are more likely to link at it. Things which are biased in nature are typically easier to be cited than things which are unbiased. See also: Alejandro M.

A systematic deviation of a value from a reference value. 2. The amount by which the average of a set of values departs from a reference value. 3. Electrical, mechanical, magnetic, or other force (field) applied to a device to establish a reference level to operate the device. 4. In telegraph signaling systems, the development of a positive or negative dc voltage at a point on a line that should remain at a specified reference level, such as zero. Note: A bias may be applied or produced by (i) the electrical characteristics of the line, (ii) the terminal equipment, and (iii) the signaling scheme.
