A technique designed to reduce response bias in self-report measures of attitudes or emotions by convincing the respondent that the researcher has a reliable and valid means, usually in the form of a sham lie detector attached to the respondent's body, of checking the truthfulness of the verbal responses. The technique was introduced by the US psychologists Edward Ellsworth Jones (1926–93) and Harold Sigall (born 1943) in an article in the journal Psychological Bulletin in 1971.
