This project develops a new theory of how persuasive communications influence social attitudes. The new theory challenges many prevailing views of persuasion and attitude change. Most contemporary theories of persuasion identify two distinct ways in which persuasive influence occurs: (1) through the persuasive message itself, based on the force of the arguments it contains, or (2) through features external to the message, such as the communicator's status or prestige, or the number of different people supporting a certain position. These theories also suggest that persuasion accomplished through message arguments is more robust, long-lasting, and resistant to subsequent change than is persuasion achieved through external features. The current project introduces a new theory in which the two seemingly different modes of persuasion actually constitute special cases of the same underlying process. These cases differ in the contents of evidence by which one may be persuaded, but not in the way those contents function to change people's attitudes. Seven experimental studies test this novel theory of persuasion. The experiments are based on an analysis showing that prior experiments have confounded general informational features (such as length/complexity, order of presentation, and relevance) with whether the information is contained inside (vs. outside) the message itself. By controlling for these confounds, it should be possible to demonstrate the functional equivalence for persuasion of these different types of information. A significant implication of the new theory is that robust, long-lasting, and resistant persuasion may be accomplished on the basis of external cues. This analysis has fundamental implications for a large number of areas in which persuasion plays a role, such as education, therapy, health and environmental-protection advocacy.

这个项目发展了一个关于说服性沟通如何影响社会态度的新理论。这个新理论挑战了许多关于说服和态度改变的流行观点。大多数当代的说服理论都确定了说服性影响发生的两种不同方式：(1)通过说服性信息本身，基于它所包含的论点的力量，或(2)通过信息的外部特征，如传播者的地位或声望，或支持某一立场的不同人的数量。这些理论还表明，通过信息论证完成的说服比通过外部特征完成的说服更有力、更持久、更能抵抗随后的变化。目前的项目引入了一种新的理论，其中两种看似不同的说服模式实际上构成了相同潜在过程的特殊情况。这些案例的不同之处在于可以说服人们的证据的内容，而不是这些内容改变人们态度的方式。七项实验研究验证了这一新颖的说服理论。这些实验基于一项分析，该分析表明，先前的实验混淆了一般信息特征（如长度/复杂性、呈现顺序和相关性）与信息是否包含在消息本身内部（vs.外部）。通过控制这些混淆，应该有可能证明说服这些不同类型信息的功能等效。新理论的一个重要含义是，强有力的、持久的、抵抗性的说服可能是在外部线索的基础上完成的。这一分析对说服发挥作用的许多领域具有根本意义，例如教育、治疗、健康和环境保护宣传。
