Σύνοψη	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.	A motivated reasoning experiment tests whether people process political information to reach conclusions they are directionally motivated to hold rather than the most accurate ones. Building on Kunda's (1990) theory and crystallized by Taber and Lodge (2006), these designs expose partisans to attitude-congruent and incongruent arguments and measure biased assimilation, disconfirmation bias, attitude polarization, and selective exposure.
