Can Inoculation Withstand Multiple Attacks

This investigation introduced multiple competitive attacks in order to assess the effectiveness of inoculation treatments in protecting established attitudes in a natural setting. A four-phase experiment was conducted involving 433 participants. The results revealed that the effectiveness of refutational inoculation messages dissipated some in the face of an additional attack. Still, refutational inoculation messages proved to be more effective than supportive, restoration, and control (no message) conditions in protecting established attitudes in the face of multiple attacks. The content of an additional attack (the same as the first attack or different) did not affect the capacity of inoculation refutational messages to confer resistance to competitive attacks.

The Attitude Base as a Moderator of the Effectiveness of Inoculation Strategy

This investigation introduced the attitude base (cognitive or affective) as a moderator in the resistance domain and effectively partitioned the role of affect from cognition by properly delineating its function. A three-phase experiment was conducted involving 290 participants. The results confirmed the role of the original elements in the process of resistance introduced by McGuire: threat and counterarguing output. Furthermore, the results indicated that inoculation messages were most effective when their content matched the attitude base. Cognitive inoculation messages generated greater resistance to counterattitudinal attacks when presented to individuals whose attitude base was primarily cognitive, rather than affective, in nature. The reverse was also found to be true as affective inoculation messages generated greater resistance to counterattitudinal attacks when presented to individuals whose attitude base was primarily affective, rather than cognitive, in nature.

Untangling Threat during Inoculation-Conferred Resistance to Influence

Threat plays a pivotal role in many theoretical explanations for how inoculation confers resistance, but some empirical data raise questions about threats role in inoculation. Our study explores some of the unresolved dimensions of threat in inoculation theory. Results indicate that an explicit forewarning included in an inoculation treatment message generates threat, as does the presence of counterarguments and their refutations. Follow-up tests suggest that the forewarning component may be most responsible for generated threat in inoculation, and that a prompt to consider experienced threat may lead to enhanced resistance to subsequent attack messages.

Examining the “Blanket of Protection” Conferred by Inoculation: The Effects of Inoculation Messages on the Cross-protection of Related Attitudes

Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection.

The General Content of Postinoculation Talk: Recalled Issue-Specific Conversations Following Inoculation Treatments

For much of inoculation theorys 50-year history, research has focused on intrapersonal processes of resistance such as threat and subvocal counterarguing. More recently, attention has shifted to interpersonal processes of inoculation-conferred resistance, specifically, postinoculation talk (PIT). This study examined the substance of PIT, and how people may talk to one another for reassurance and advocacy following an inoculation. Findings indicate advocacy attempts were significantly greater within the inoculation condition. Those inoculated were more likely to a) pass along material included in the inoculation treatment, b) share issue-relevant novel material, c) talk about topics related to the target issue, and d) be challenged by conversational partners when attempting advocacy. Results help explain what inoculated individuals talk about following an inoculation treatment, and how PIT may spread the process of resistance along social networks.

Beyond Simple Inoculation: Examining the Persuasive Value of Inoculation for Audiences with Initially Neutral or Opposing Attitudes

It is well established that—among individuals who hold an attitude toward a topic—inoculation messages can help promote resistance to counterattitudinal attacks. Yet, the utility of inoculation theory for communication campaigns may ultimately depend upon the effects inoculation messages have on individuals who are initially opposed or neutral regarding the topic. A three-phase experiment (N = 282) was conducted to examine the effects of inoculation and supportive messages among individuals with neutral and opposing attitudes. The results revealed that, compared to the control groups, inoculation and supportive messages moved neutral and opposing attitudes in the message-advocated direction. Moreover, inoculation and supportive messages protected these attitudinal gains from attack-message-induced slippage. Since inoculation messages outperformed supportive messages, inoculation has potential utility for communication campaigns.

Leading the Way in New Product Introductions: Publicity's Message Sequencing Success With Corporate Credibility and Image as Moderators

This investigation further nuanced previous designs in comparing the effectiveness of 4 IMC message sequencing strategies (publicity–publicity, publicity–advertising, advertising–publicity, and advertising–advertising) by introducing them into a new context—new product introductions. In addition, this investigation introduced corporate image and credibility as moderators of the effectiveness of sequence strategies. A 2-phase experiment was conducted involving 423 participants. The results revealed the publicity–publicity sequence strategy is most effective in generating positive product attitude and purchase intent, followed by either sequence of publicity and advertising, with the advertising–advertising strategy being least effective. Positive corporate image and high credibility attenuated the effectiveness of the publicity strategy.

Vaccinating Voters: Surveying Political Campaign Inoculation Scholarship

Inoculation theory has seen dramatic theoretical development since it was first introduced in the early 1960s, and applied research has explored its efficacy in such domains as politics, health, and commerce. This chapter notes a dearth in political campaign inoculation scholarship in recent years and calls for renewed interest. A survey of inoculation research offers a nuanced portrait of how inoculation has functioned in campaigns, yet several findings remain unexplained by the theory. The chapter concludes with proposals for future political campaign inoculation research, exploring new campaign technologies and new insights into how inoculation functions in political campaigns.

Using an inoculation message approach to promote public confidence in protective agencies

ABSTRACT This investigation tested the effectiveness of inoculation as a pre-crisis strategy in combating the effects of politically motivated violent acts. A four-phase experiment was conducted involving 355 national consumer panel participants. The findings indicate that inoculation can be an effective pre-crisis message strategy as it was successful in enhancing public beliefs in the ability of government agencies to prevent, and minimize the effects of, violent acts. This strategy also created a ‘blanket of protection’ that extended beyond the focal politically motivated attack event as it enhanced the confidence in government agencies to manage national crises in general. Inoculation was also effective in lowering the intensity of experienced fear evoked by the threat of violent attacks and it enhanced the ability of individuals to cope with the aftermath of a crisis.

Using Postinoculation Talk to Strengthen Generated Resistance

This study builds on the burgeoning concept of integrating a vocal component into inoculation-generated resistance. Specifically, this research attempts to isolate the vocal and subvocal components of the inoculation process to clarify recent research that has raised questions about the long-standing proposition that inoculation-motivated counterarguing is an exclusively subvocal process. Furthermore, it separately measures belief levels and belief certainty. The pattern of results indicates that postinoculation talk (PIT) following exposure to the inoculation message can boost belief certainty. These findings complement recent work that suggests that the content of PIT serves reassurance and advocacy purposes.
