概要	An issue framing experiment manipulates how a political issue is described, emphasizing different considerations, to test how framing shifts opinion. Nelson, Clawson and Oxley's (1997) classic study showed that framing a Klan rally as a free-speech issue versus a public-order issue changed tolerance judgments, and Chong and Druckman (2007) systematized framing theory and the experimental methods used to estimate framing effects.	The Political Knowledge Scale measures the range of factual information about politics that citizens hold and can retrieve, operationalized as a battery of factual quiz items. Delli Carpini and Keeter (1993, 1996) established the canonical short batteries (often five items) and argued that general political knowledge, not domain-specific information, is the most useful and reliable construct for survey research.
