The present research proposes that sources in the numerical majority (vs. minority) can affect persuasion by influencing the confidence with which people hold their thoughts in response to the persuasive message. Participants received a persuasive message composed of either strong or weak arguments that was presented by a majority or a minority source. Consistent with the self-validation hypothesis, we predicted and found that the majority (vs. minority) status of the source increased the…

Multiple roles for majority versus minority source status on persuasion when source status follows the message

This research shows that numerical majority (vs minority) status of the source can affect persuasion by different processes when induced after message processing. Specifically, we argue that source

Evaluating the Message or the Messenger? Implications for Self-Validation in Persuasion

It is postulated that different foci can affect how a source validates message-related cognitions, and when participants were focused on the issue, self-validation was greater when credibility was high rather than low—regardless of argument quality.

Source Credibility and Persuasion

Highly credible communicators have been found to elicit greater confidence and attitudes that are based more on recipients’ thoughts compared with non-credible sources, and greater self-validation may emerge when a communicator lacks rather than possesses credibility.

Power and Persuasion: Processes by Which Perceived Power Can Influence Evaluative Judgments

The present review focuses on how power—as a perception regarding the self, the source of the message, or the message itself—affects persuasion. Contemporary findings suggest that perceived power can

Consumer Persuasion: Indirect Change and Implicit Balance

The present research examines two main issues relevant to consumer persuasion: (1) whether automatic evaluations can change (both directly and indirectly) in response to verbal ads that engage

Changing prejudiced attitudes, promoting egalitarianism, and enhancing diversity through fundamental processes of persuasion

ABSTRACT We review work from persuasion science relevant to reducing prejudiced attitudes. We begin by introducing the idea that the thoughts people generate – their number and valence – are critical

Tourism Marketing Stimulus Characteristics: A Self-Validation Analysis of Iran

Prior self-validation hypothesis studies suggest that an individual’s attitude toward advertising is affected by the cognitive processing of the message and the valence of emotion. Yet, the effect of

Hedonic vs. epistemic goals in processing persuasive communications: Revisiting the role of personal involvement

Practitioners and researchers interested in designing wise interventions often recommend increasing personal involvement to be successful. Early research demonstrated that personal involvement

Rejecting a Bad Option Feels Like Choosing a Good One

A novel framing effect, attribute matching, is shown to increase decision confidence and, ultimately, consensus estimates by increasing feelings of metacognitive ease by matching a salient attribute of a decision frame with that of a decisions’ options facilitates decision-making.

When do Online User-Generated Reviews Really Matter? A Self-Validation Analysis

It is proposed to show that different online consumer reviews or digital word-of-mouth could have comparable impacts in changing consumers’ expressed preferences, but under some conditions, preference shifts or attitude changes induced by online peer reviews may not necessarily reflect people’s purchase intentions.

The Effects of Minority/Majority Source Status on Attitude Certainty: A Matching Perspective

Three studies tested the hypothesis that when people receive persuasive messages from sources in the minority or majority, their attitude certainty can be determined by the extent to which source status and perceived argument quality match or mismatch, and suggest that attitudes can be high or low following minority ormajority messages, depending on processing motivation and message recipients' assessments of other persuasive evidence.

Minority Versus Majority Influence and Uncertainty Orientation: Processing Persuasive Messages on the Basis of Situational Expectancies

Individual differences in uncertainty orientation moderated strength and direction of information processing in all cases, and support for the hypothesis that was related to nonsystematic processing was less clear.

Two experiments addressed the issue of whether endorsement of a position by a numerical majority or a minority leads to greater scrutiny of the information presented in a persuasive message. In

Two experiments examined the extent to which attitudes changed following majority and minority influence are resistant to counter-persuasion. In both experiments participants' attitudes were measured

The persuasion literature has examined several mechanisms that have contributed to understanding the effectiveness of credible, attractive, similar, and powerful sources. These traditionally studied

The authors studied effects of majority and minority support on persuasion for nondiscrepant positions. In two experiments, students (N = 188) read messages on previously unknown attitude objects.

Resisting Persuasion by Illegitimate Means: A Metacognitive Perspective on Minority Influence

It is proposed that when people initially resist persuasive messages from sources in the numerical minority, they can lose attitude certainty if they perceive that they have based their attitudes on the source's minority status and also believe this is an illegitimate basis for resistance.
