[2] [3] Studies have shown that interviewing techniques such as asking leading questions and closed-ended questions can influence the responses given by the interviewee. [2] [3] Many of the techniques were explored by Elizabeth Loftus, a researcher who studied eyewitness testimony, the misinformation effect, and false memories. [citation needed]
A biased question or questionnaire encourages respondents to answer one way rather than another. [20] Even questions without bias may leave respondents with expectations. The order or grouping of questions is also relevant; early questions may bias later questions. Loaded questions evoke emotional responses and may skew results.
A leading question is a question that suggests a particular answer and contains information the examiner is looking to have confirmed. [1] The use of leading questions in court to elicit testimony is restricted in order to reduce the ability of the examiner to direct or influence the evidence presented.
In psychology and cognitive science, a memory bias is a cognitive bias that either enhances or impairs the recall of a memory (either the chances that the memory will be recalled at all, or the amount of time it takes for it to be recalled, or both), or that alters the content of a reported memory. There are many types of memory bias, including:
Among the factors that impact the results of opinion polls are the wording and order of the questions being posed by the surveyor. Questions that intentionally affect a respondents answer are referred to as leading questions. Individuals and/or groups use these types of questions in surveys to elicit responses favorable to their interests. [24]
A suggestive question is one that implies that a certain answer should be given in response, [1] [2] or falsely presents a presupposition in the question as accepted fact. [3] [4] Such a question distorts the memory thereby tricking the person into answering in a specific way that might or might not be true or consistent with their actual feelings, and can be deliberate or unintentional.
Social desirability bias is a type of response bias that influences a participant to deny undesirable traits, and ascribe to themselves traits that are socially desirable. [2] In essence, it is a bias that drives an individual to answer in a way that makes them look more favorable to the experimenter. [1] [2] This bias can
The experimenter may introduce cognitive bias into a study in several ways — in the observer-expectancy effect, the experimenter may subtly communicate their expectations for the outcome of the study to the participants, causing them to alter their behavior to conform to those expectations. Such observer bias effects are near ...
