Examines the relation between political knowledge & interest in public affairs, after George Bishop's (1987) observation that an inability to answer a political knowledge question decreased self-reported interest in public affairs. This effect was unaffected by the introduction of up to 101 unrelated buffer items. Explanations for the effect are tested here by providing 454 respondents (Rs) to a national telephone survey with an alternative explanation to lack of knowledge. Results reveal that a single buffer item giving Rs an external explanation for their lack of knowledge greatly reduced the context effect. Implications for the operation of buffer items are discussed. 1 Appendix, 11 References. Adapted from the source document.
