Abstract: | Bishop (1987) observed that being unable to answer a politicalknowledge question decreased self-reported interest in publicaffairs. This effect was unaffected by the introduction of upto 101 unrelated buffer items. In contrast, a single bufferitem that provided respondents with an external explanationfor their lack of knowledge greatly reduced the context effectin the present study. Implications for the operation of bufferitems are discussed. |
