Persuasive Messages Will Not Increase COVID-19 Vaccine Acceptance: Evidence from a Nationwide Online Experiment.

Although mass vaccination is the best way out of the pandemic, the share of skeptics is substantial in most countries. Social campaigns can emphasize the many arguments that potentially increase acceptance for vaccines: e.g., that they have been developed, tested, and recommended by doctors and scientists; and that they are safe, effective, and in demand. We verified the effectiveness of such messages in an online experiment conducted in February and March 2021 with a sample of almost six thousand adult Poles, which was nationally representative in terms of key demographic variables. We presented respondents with different sets of information about vaccinating against COVID-19. After reading the information bundle, they indicated whether they would be willing to be vaccinated. We also asked them to justify their answers and indicate who or what might change their opinion. Finally, we elicited a number of individual characteristics and opinions. We found that nearly 45% of the respondents were unwilling to be vaccinated, and none of the popular messages we used was effective in reducing this hesitancy. We also observed a number of significant correlates of vaccination attitudes, with men, older, wealthier, and non-religious individuals, those with higher education, and those trusting science rather than COVID-19 conspiracy theories being more willing to be vaccinated. We discuss important consequences for campaigns aimed at reducing COVID-19 vaccine hesitancy.

Explainable AI meets persuasiveness: Translating reasoning results into behavioral change advice.

Explainable AI aims at building intelligent systems that are able to provide a clear, and human understandable, justification of their decisions. This holds for both rule-based and data-driven methods. In management of chronic diseases, the users of such systems are patients that follow strict dietary rules to manage such diseases. After receiving the input of the intake food, the system performs reasoning to understand whether the users follow an unhealthy behavior. Successively, the system has to communicate the results in a clear and effective way, that is, the output message has to persuade users to follow the right dietary rules. In this paper, we address the main challenges to build such systems: (i) the Natural Language Generation of messages that explain the reasoner inconsistency; and, (ii) the effectiveness of such messages at persuading the users. Results prove that the persuasive explanations are able to reduce the unhealthy users' behaviors.

Designing information provision to serve as a reminder of altruistic benefits: A case study of the risks of air pollution caused by industrialization.

A well-known phenomenon is that humans perceive risks to threaten future generations as more dangerous in many cases. However, this tendency could be changed depending on certain conditions and could potentially be explained by the evolution of altruism. Our multi-agent simulation model, which was constructed to identify attributes contributing to subjective assessment of a risk source based on kin selection theory, showed that support from relatives can affect the agents’ subjective risk assessment. We utilize this insight, which has never been explored in the context of nudge, to show that real-world messages reminding respondents that they are supported by their relatives can moderate the perception of a risk source as extremely dangerous. A randomized control trial based on an internet questionnaire survey was conducted to identify the intervention effect of such messages, using air pollution caused by industrialization as the risk source for the case study. Our analysis suggests that messages moderate extreme attitudes. Presentation of additional visual information can boost the sense of familial support and increase the effect of a message compared with a message comprising only textual information. The attributes and personality traits of the respondents who are responsive to the intervention message are also discussed.

PROPAGANDA OF SUCCESS IN THE AREA OF THE STATE’S SOCIAL AND ECONOMIC POLICY

An attentive observer of the social and political life in Poland has certainly noticed changes in the way the government communicates with the public since the United Right (Zjednoczona Prawica) came to power at the end of 2015. Media messages, saturated with persuasive elements, have ceased to have an exclusively informative function. The government, with the help of the media, especially the public media, has begun to practise propaganda on a large scale. One of its manifestations is the impression created in the society that success has been achieved in the social and economic sphere. However, this is often at the expense of a breach of ethical standards in terms of content and form. The aim of this study is to examine whether and to what extent respondents critically analyse the content of media messages related to the “Family 500+” (Rodzina 500+) programme, as well as to the unemployment rate and the GDP dynamics. A survey conducted by the author shows that the government’s propaganda has not been very effective in shaping the knowledge and attitudes of the interviewees. The limited effectiveness of such messages can be linked to the sources of information used by young people participating in the survey.

Strategies to customize responsible gambling messages: a review and focus group study

BackgroundResponsible gambling messages are widely used as a tool to enable informed choice and encourage appropriate gambling behavior. It is generally accepted that gamblers have different levels of risk of developing gambling problems and require various harm minimization tools and resources. Therefore, it is reasonable to expect that responsible gambling messages should be customized and target specific groups of gamblers. This project aimed to understand hypothesized differences between cohorts of gamblers and receive qualitative feedback on archetypal targeted messages used to increase use of responsible gambling tools.MethodsFocus groups were held to test messages for specific cohorts: young adults (18–24 years), seniors (60+ years), frequent gamblers (weekly), and gamblers of skill-based games (poker, sports betting).ResultsCohorts exhibited different preferences and responses to message archetypes. Seniors preferred messages about limit setting, whilst young adults and frequent gamblers responded to messages about their own play and expertise. Skill game gamblers were interested in the odds of winning and their own outcomes over time. However, all groups agreed that using positive, non-judgmental language in messaging is important.ConclusionsThis research makes an important contribution to the field by demonstrating that the wording of message content will likely influence the effectiveness of such messages differentially across various groups of gamblers for engaging gamblers in harm reduction tools. Guidance is provided on themes that can be used by public health marketers.

Two observational studies examining the effect of a social norm and a health message on the purchase of vegetables in student canteen settings

There is some evidence from laboratory-based studies that descriptive social-norm messages are associated with increased consumption of vegetables, but evidence of their effectiveness in real-world settings is limited. In two observational field studies taking an ecological approach, a vegetable-related social norm (e.g. “Did you know that most students here choose to eat vegetables with their meal?”), and a health message (e.g. “Did you know that students who choose to eat vegetables have a lower risk of heart disease?”) were displayed in two different student canteens. Purchases were observed during three stages: baseline, intervention (when the posters were displayed) and immediate post-intervention (when the posters had been removed). Study 1 (n = 7598) observed the purchase of meals containing a portion of vegetables and Study 2 (n = 4052) observed the purchase of side portions of vegetables. In Study 1, relative to baseline, the social-norms intervention was associated with an increase in purchases of vegetables (from 63% to 68% of meals; OR = 1.24, CI = 1.03–1.49), which was sustained post-intervention (67% of meals; OR = 0.96, CI = 0.80–1.15). There was no effect of the health message (75% of meals at baseline, and 74% during the intervention; OR = 0.98, CI = 0.83–1.15). In Study 2, relative to baseline, there was an effect of both the social norm (22.9% of meals at baseline, rising to 32.5% during the intervention; OR = 1.62, CI = 1.27–2.05) and health message (rising from 43.8% at baseline to 52.8%; OR = 0.59, CI = 0.46-0.75). The increase was not sustained post-intervention for the social norm intervention (22.1%; OR = 0.59, CI = 0.46-0.75), but was sustained for the health intervention (48.1%; OR = 0.83, CI = 0.67–1.02). These results support further testing of the effectiveness of such messages in encouraging healthier eating and indicate the need for larger-scale testing at multiple sites using a randomised-controlled design.

Effect of Health Messages on Alcohol Attitudes and Intentions in a Sample of 16-17-Year-Old Underage Drinkers.

Background: Responsible drinking messages (RDMs) are a key component of many education-based interventions for reducing alcohol harms. The evidence base for the effectiveness of RDMs is extremely limited, with some recent research suggesting iatrogenic effects of such messages. Objective: To examine the effects of exposure to health messages on attitudes towards drinking and drunkenness, and intentions to drink and get drunk, amongst underage drinkers. Methods: Ninety-four underage drinkers were recruited from colleges in the UK. Participants were either actively or passively exposed to one of two health messages (RDM or general wellbeing). Measures of attitudes and intentions towards drinking and drunkenness were obtained one week before and immediately after participation in the study. A unit estimation task was also included. Results: Active exposure to RDMs led to more positive attitude towards drunkenness, while passive exposure led to more negative attitudes. Passive RDM exposure led to increased intentions to get drunk in future. Wellbeing posters produced the opposite effect in some but not all of these measures. Conclusions: Exposure to RDMs may have some beneficial effects in terms of creating more negative attitudes towards alcohol consumption, but we also identified potential iatrogenic effects regarding attitudes and intentions towards drunkenness amongst an underage sample of drinkers. Further research is required to better understand optimal ways of framing RDMs to produce positive changes in attitudes, intentions, and prospective drinking behaviour.

Los efectos de la comunicación política en el compromiso político de los jóvenes en la elección presidencial mexicana de 2012

Do modern forms of political communication generate political engagement or rather political disaffection among young citizens? While media malaise theories argue that media and campaigns messages have a negative impact on citizens’ political involvement, cognitive mobilization theories contend that the effects of such messages on political engagement is rather positive. This article analyzes the effects that media and campaign messages had on civic engagement of young people during the 2012 Mexican presidential election in the light of mobilization and media malaise theories, by using multiple regression analysis with data from the National Survey of Political Culture of the Youth 2012. [n general, the results of the analysis lend more support to the mobilization theories than to theories of media malaise.

Negative Campaigning, Fundraising, and Voter Turnout: A Field Experiment

Negative campaigning is a recurring feature of political competition, though its persistence is puzzling in light of research showing that the public dislikes it. Why do candidates risk alienating voters by going negative? One answer may lie in the large empirical literature on persuasion indicating that negative messages are more effective than positive messages in getting individuals to do many things, including voting and purchasing goods. Negative messages may work better because they contain more information, and individuals use this to update beliefs when making decisions. Or, the tone of the message may change preferences, without providing additional information. Which element, information or tone, underlies the effectiveness of such messages has not been clearly identified. We attempt to do so by using a field experiment in two elections for local office. We test the effect of a negative letter, a positive letter, or no letter sent to partisans on two measurable activities: campaign donations and voter turnout. We find no effect of message tone on campaign donations. However, we do find that tone is important in driving voter turnout, and this effect is separate from the effect of information. In our environment, going negative never hurts the candidates.

Self-Deprecating Humor Versus Other-Deprecating Humor in Health Messages

Humor is sometimes used in health messages. However, little is known about contingencies under which different types of humor may or may not be effective. This experiment crossed humorous versus nonhumorous and self- versus other-deprecating messages about binge drinking, and tested how differences in personal investment in alcohol use moderates the effects of such messages on college binge drinkers. Results showed significant 3-way interaction effects on subjective norms and behavioral intentions largely consistent with hypotheses. Assessment of significant differences in the interactions indicated that for binge drinkers who were not high in personal investment in alcohol use, other-deprecating humor tended to reduce their perceived subjective norms about the acceptability of binge drinking behavior and their behavioral intentions. The effect of the experimental manipulation on subjective norms among these binge drinkers was shown to mediate the effect on intentions to binge drink in the future. Theoretical and practical implications are discussed.

E-mail to Promote Colorectal Cancer Screening Within Social Networks: Acceptability and Content

Effective techniques to encourage colorectal cancer screening in underscreened populations have included social support interventions and e-mail reminders from physicians. Personalized e-mail messages to promote colorectal cancer screening within social networks could be even more effective but have not been studied. The authors interviewed 387 e-mail users, aged 42–73 years in Georgia, Hawaii, and Massachusetts. Participants were asked to edit a sample message in which the sender shares a recent colonoscopy experience and urges the recipient to discuss colorectal cancer screening with a doctor. For those reporting willingness to send this message, changes to the message and suggested subject lines were recorded. Edited text was analyzed for content and concordance with original message. The majority of participants (74.4%) were willing to e-mail a modifiable message. Of those willing, 63.5% edited the message. Common edits included deletion (17.7%) or modification (17.4%) of a negatively framed sentence on colon cancer risks and addition or modification of personalizing words (15.6%). Few edits changed the meaning of the message (5.6%), and even fewer introduced factual inaccuracies (1.7%). Modifiable e-mail messages offer a way for screened individuals to promote colorectal cancer screening to social network members. The accuracy and effects of such messages should be further studied.

Ballot Secrecy Concerns and Voter Mobilization

Recent research finds that doubts about the integrity of the secret ballot as an institution persist among the American public. We build on this finding by providing novel field experimental evidence about how information about ballot secrecy protections can increase turnout among registered voters who had not previously voted. First, we show that a private group’s mailing designed to address secrecy concerns modestly increased turnout in the highly contested 2012 Wisconsin gubernatorial recall election. Second, we exploit this and an earlier field experiment conducted in Connecticut during the 2010 congressional midterm election season to identify the persistent effects of such messages from both governmental and non-governmental sources. Together, these results provide new evidence about how message source and campaign context affect efforts to mobilize previous non-voters by addressing secrecy concerns, as well as show that attempting to address these beliefs increases long-term participation.

The perceived value of maths and academic self-efficacy in the appraisal of fear appeals used prior to a high-stakes test as threatening or challenging

Previous work has examined how messages communicated to students prior to high-stakes exams, that emphasise the importance of avoiding failure for subsequent life trajectory, may be appraised as threatening. In two studies, we extended this work to examine how students may also appraise such messages as challenging or disregard them as being of little relevance. In study one we piloted a questionnaire with students studying for their school leaving qualification in maths. Threat appraisals were correlated with low academic self-efficacy, high attainment value and low intrinsic value. Challenge appraisals were correlated with high academic self-efficacy, and high intrinsic, extrinsic and attainment value. In study two, we manipulated attainment value and academic self-efficacy in a series of vignettes. High value and high academic self-efficacy lead to challenge appraisals, high value but low academic self-efficacy lead to threat appraisals and low value lead to a disregarding of messages. These findings show that the relevance of messages is judged on attainment value in a primary appraisal and as a challenge or threat in a subsequent appraisal, based on the expectation of success or failure. These findings also highlight how the effectiveness of such messages may differ depending on student characteristics.

Pass the popcorn: “Obesogenic” behaviors and stigma in children's movies

ObjectiveTo determine the prevalence of obesity-related behaviors and attitudes in children’s movies.Design and MethodsWe performed a mixed-methods study of the top-grossing G- and PG-rated movies, 2006–2010 (4 per year). For each 10-minute movie segment the following were assessed: 1) prevalence of key nutrition and physical activity behaviors corresponding to the American Academy of Pediatrics obesity prevention recommendations for families; 2) prevalence of weight stigma; 3) assessment as healthy, unhealthy, or neutral; 3) free-text interpretations of stigma.ResultsAgreement between coders was greater than 85% (Cohen’s kappa=0.7), good for binary responses. Segments with food depicted: exaggerated portion size (26%); unhealthy snacks (51%); sugar-sweetened beverages (19%). Screen time was also prevalent (40% of movies showed television; 35% computer; 20% video games). Unhealthy segments outnumbered healthy segments 2:1. Most (70%) of the movies included weight-related stigmatizing content (e.g. “That fat butt! Flabby arms! And this ridiculous belly!”).ConclusionsThese popular children’s movies had significant “obesogenic” content, and most contained weight-based stigma. They present a mixed message to children: promoting unhealthy behaviors while stigmatizing the behaviors’ possible effects. Further research is needed to determine the effects of such messages on children.

Using Nonpecuniary Strategies to Influence Behavior: Evidence from a Large-Scale Field Experiment

Policymakers are increasingly using norm-based messages to influence individual decision making. We partner with a metropolitan water utility to implement a natural field experiment to examine the effect of such messages on residential water demand. The data, drawn from more than 100,000 households, indicate that social comparison messages had a greater influence on behavior than simple prosocial messages or technical information alone. Moreover, our data suggest that social comparison messages are most effective among households identified as the least price sensitive: high users. Yet the effectiveness of such messages wanes over time. Our results thus highlight important complementarities between pecuniary and nonpecuniary strategies.

An Empirical Test of the Materialist Framework for Understanding the General Population's Reaction to Nonpersonalized Genetic Health Messages

Genetic health messages are increasingly prevalent in our society. The materialist framework of laypeople's genetic knowledge may provide a good basis for understanding the effects of such messages on preventive behavior and related health cognitions. This study provides an empirical test of the predictions of this framework. We presented 929 participants who were aware or unaware of the existence of genetic risk factors for salt sensitivity with either a genetic health message or a general health message about salt sensitivity. Baseline, immediate follow-up, 1-month follow-up, and 6-month follow-up questionnaires assessed risk perception, intention, and salt consumption. Compared with the general health message, previously unaware participants reported lower susceptibility to, and lower severity of, salt sensitivity and lower intentions to restrict salt intake immediately after reading the genetic health message, but not at the 1- and 6-month follow-ups. No such effects were observed for previously aware participants. In addition, the authors observed no effect of health message type on self-reported salt consumption. The authors' findings support the validity of the materialist framework for understanding laypeople's knowledge of genetics. On the basis of the results, several implications were deduced for public education of genetics.

The Persistence of Treatment Effects with Norm-Based Policy Instruments: Evidence from a Randomized Environmental Policy Experiment

Policymakers increasingly use norm-based messages to promote conservation efforts. Despite the apparent success of such strategies, empirical analyses have thus far focused exclusively on short-run effects. From a policy perspective, however, whether and how such strategies influence behavior in the long-run is of equal interest. We partner with a metropolitan water utility to implement a natural field experiment examining the effect of such messages on longer-run patterns of water use. Empirical results are striking. While appeals to pro-social preferences affect short-run patterns of water use, only messages augmented with social comparisons have a lasting impact on water demand.

Tailored messages, external barriers, and women's utilization of professional breast cancer screening over time

The efficacy of tailored messages on women's utilization of professional breast screening over time has not been examined often or in combination with external barriers (e.g., costs and access). The objectives of this study were to test the effects of alternative messages on mammography and clinical breast examination (CBE) utilization over time and to examine the combined effects of such messages and external barriers. In a randomized, controlled trial, three message conditions were compared: no message (control group), recommendations about screening, or recommendations plus tailored discussion (on beliefs, feelings, costs, and access). Messages were delivered by advanced practice nurses over the telephone. Participants were women ages 51-80 years who had not had mammography in the prior 13 months. Outcome measures were women's mammography and CBE utilization 3-6 months postintervention (short-term follow-up) and 13-16 months after short-term follow-up (long-term follow-up). Both messages promoted mammography and CBE utilization at short-term follow-up. Utilization increased over time in all groups. Mammography utilization was greater for the tailored-message group compared with the recommendations-only group at long-term follow-up. Messages and external barriers had combined effects (Ps < 0.01). Among participants with high external barriers, participants in the message conditions-especially the tailored message-had the highest screening rates; among participants with low barriers, screening rates were similar across conditions. Clinicians can tailor discussions on beliefs, feelings, cost, and access about screening to promote professional breast screening over time, especially with women who have not had mammograms as recommended and who have external barriers to screening.

Directed forgetting and feedback in written instruction

In three experiments, we examined the effects of directed forgetting messages on item recall. Using a variety of materials and conditions, we observed no main effects of such messages on recall. However, analyses of question and feedback study time, response certitude, and conditional probability revealed a number of significant effects. Effects of feedback were consistently strong and may have masked the benefits of directed forgetting. Other results were consistent with previous research in the feedback paradigm.
