概要	Elaboration likelihood analysis applies Petty and Cacioppo's 1986 Elaboration Likelihood Model (ELM) to study persuasion through experiments that cross message argument quality with peripheral cues under varying levels of audience motivation and ability to think. It identifies whether attitude change travels the central route — effortful scrutiny of arguments — or the peripheral route, reliance on simple cues like source attractiveness or message length.	A framing effects experiment is a randomized design that isolates the causal impact of how a message is framed — which considerations it emphasizes — on people's attitudes, judgments, or behavior. By randomly assigning participants to read otherwise comparable messages that differ only in their frame, it provides the causal counterpart to the descriptive framing analysis of media content.
