Neural mechanisms of the continued influence effect of misinformation: Analysis based on fMRI causal connectivity

The continued influence effect of misinformation (CIEM) can negatively affect individuals’ reasoning and judgment processes. This research aims to enhance the correction of misinformation and foster rational judgement by investigating the internal brain mechanisms involved in the processing of the CIEM through the use of task-based functional magnetic resonance imaging combined with Granger causality analysis. Our findings demonstrate notable effective interactions in varying directions between the left inferior frontal gyrus and middle temporal gyrus during the encoding phase, and between the right anterior cingulate gyrus and left inferior occipital gyrus in the retrieval phase. These insights elucidate the roles of mental model updating and retrieval failure in the processing of CIEM, offering more granular evidence to support the differentiation in processing phases.

Misunderstanding the harms of online misinformation.

The controversy over online misinformation and social media has opened a gap between public discourse and scientific research. Public intellectuals and journalists frequently make sweeping claims about the effects of exposure to false content online that are inconsistent with much of the current empirical evidence. Here we identify three common misperceptions: that average exposure to problematic content is high, that algorithms are largely responsible for this exposure and that social media is a primary cause of broader social problems such as polarization. In our review of behavioural science research on online misinformation, we document a pattern of low exposure to false and inflammatory content that is concentrated among a narrow fringe with strong motivations to seek out such information. In response, we recommend holding platforms accountable for facilitating exposure to false and extreme content in the tails of the distribution, where consumption is highest and the risk of real-world harm is greatest. We also call for increased platform transparency, including collaborations with outside researchers, to better evaluate the effects of online misinformation and the most effective responses to it. Taking these steps is especially important outside the USA and Western Europe, where research and data are scant and harms may be more severe.

Factors Influencing COVID-19 Vaccine Confidence and Uptake in Australian Adults.

In January 2021, Australia initiated a national COVID-19 vaccine rollout strategy but faced setbacks, leading to negative press and media controversy, which may have diminished vaccine confidence. This study aimed to assess the factors influencing vaccine confidence in Australian adults (≥18 years of age) following the administration of a COVID-19 vaccine. Conducted at Blacktown Hospital, Sydney, a cross-sectional survey with 1053 respondents gauged vaccine confidence and influencing factors. The results showed overall high confidence (mean score 33/40). Trusted sources included the Australian Department of Health (77.8%), NSW Health (76.7%), and general practitioners (53.7%), while social media was distrusted (5.9%). The motivations for vaccination varied: university-educated individuals prioritised personal health (X2 = 17.81; p < 0.001), while religious and/or older respondents (≥50 years of age) emphasised community (X2 = 11.69; p < 0.001) and family protection (X2 = 17.314; p < 0.001). Multivariate logistic regression revealed use of the Australian Department of Health website as a trusted source of COVID-19 information as the strongest predictor of high confidence (>30; OR 1.43; p = 0.041), while exposure to fake news decreased confidence (OR 0.71; p = 0.025). The study underscores the importance of reliable health information sources in bolstering vaccine confidence and highlights the detrimental effects of misinformation. Promoting awareness of trustworthy health channels is crucial to combat vaccine hesitancy in Australia.

Investigating the Effects of Misinformation as Infopathogens: Developing a Model and Thought Experiment

Previously, it has been shown that transmissible and harmful misinformation can be viewed as pathogenic, potentially contributing to collective social epidemics. In this study, a biological analogy is developed to allow investigative methods that are applied to biological epidemics to be considered for adaptation to digital and social ones including those associated with misinformation. The model’s components include infopathogens, tropes, cognition, memes, and phenotypes. The model can be used for diagnostic, pathologic, and synoptic/taxonomic study of the spread of misinformation. A thought experiment based on a hypothetical riot is used to understand how disinformation spreads.

Misinformation and Disinformation: Unravelling the Web of Deceptive Information

In the current digital era, misinformation and deception spread quickly, posing serious problems for civilizations everywhere. Online platforms and social media networks have become a haven for misinformation, which is defined as the unintended distribution of erroneous or inaccurate information, and disinformation, which is the deliberate spread of misleading information with the intent to deceive. This essay examines the subtle distinctions between misinformation and disinformation, highlighting their crucial roles in influencing public opinion and public debate globally. Examining the effects of misinformation and disinformation on people, groups, and democratic processes, the difficulties brought about by the quick dissemination of erroneous information and the decline in public confidence in traditional media and institutions are highlighted. Furthermore, an analysis is conducted on the legal and regulatory frameworks in India and throughout the world that deal with misinformation and disinformation. The analysis identifies important policies and laws that are meant to stop the spread of lies. The paper concludes with suggestions and solutions for dealing with misinformation and disinformation. It emphasises the value of fact-checking programmes, media literacy education, and cooperative efforts between governments, media outlets, and civil society to protect democratic values and advance information integrity in the digital age.

Trusted sources of information on COVID-19 vaccine in Uganda

BackgroundThe COVID-19 pandemic has dramatically impacted communities worldwide, particularly in developing countries. To successfully control the pandemic, correct information and more than 80% vaccine coverage in a population were required. However, misinformation and disinformation could impact this, thus increasing COVID-19 vaccine hesitancy in communities. Several studies observed the effect of misinformation and disinformation on COVID-19 vaccine acceptance and other responses to the pandemic in the African continent. Thus, the most trusted sources of information on COVID-19 vaccines are critical for the successful management and control of the pandemic. This study aimed to assess the most trusted sources of information on COVID-19 vaccines during the pandemic in Uganda.MethodsWe conducted a cross-sectional study on 587 adult population members in northern Uganda. Single-stage stratified and systematic sampling methods were used to select participants from northern Uganda. An interviewer-administered questionnaire with an internal validity of Cronbach’s α = 0.72 was used for data collection. An Institution Review Board (IRB) approved this study and Stata version 18 was used for data analysis. A Pearson Chi-square (χ2) analysis was conducted to assess associations between trusted sources of COVID-19 vaccine information and selected independent variables. Fisher’s exact test considered associations when the cell value following cross-tabulation was < 5. A P-value < 0.05 was used as evidence for an association between trusted sources of information and independent variables. All results were presented as frequencies, proportions, Chi-square or Fisher’s exact tests, and P-values at 95% Confidence Intervals (CI).ResultsIn a study of 587 participants, most were males, 335(57.1%), in the age group of 25–34 years, 180(31.4%), and the most trusted source of COVID-19 vaccine information were the traditional media sources for example, Televisions, Radios, and Newspapers, 349(33.6%). There was no significant association between sex and trusted sources of COVID-19 vaccine information. However, by age-group population, COVID-19 vaccine information was significantly associated with internet use (14.7% versus 85.3%; p = 0.02), information from family members (9.4% versus 90.6%; p < 0.01), and the Government/Ministry of Health (37.9% versus 62.1%; p < 0.01). Between healthcare workers and non-health workers, it was significantly associated with internet use (32.2% versus 67.8%; p = 0.03), healthcare providers (32.5% versus 67.5%; p < 0.018), the Government/Ministry of Health (31.1% versus 68.9%; p < 0.01), and scientific articles (44.7% versus 55.3%; p < 0.01).ConclusionThe most trusted sources of COVID-19 vaccine information in northern Uganda were Televisions, Radios, and Newspapers. The trusted sources of COVID-19 vaccine information were not significantly different between males and females. However, there were significant differences among age groups and occupations of participants with younger age groups (≤ 44 years) and non-healthcare workers having more trust in Televisions, Radios, and Newspapers. Thus, for effective management of an epidemic, there is a need for accurate communication so that misinformation, disinformation, and malinformation in the era of “infodemic” do not disrupt the flow of correct information to communities.

Free entropy minimizing persuasion in a predictor–corrector dynamic

Persuasion is the process of changing an agent’s belief distribution from a given (or estimated) prior to a desired posterior. A common assumption in the acceptance of information or misinformation as fact is that the (mis)information must be consistent with or familiar to the individual who accepts it. We model the process as a control problem in which the state is given by a (time-varying) belief distribution following a predictor–corrector dynamic. Persuasion is modeled as the corrector control signal with the performance index defined using the Fisher–Rao information metric, reflecting a fundamental cost associated to altering the agent’s belief distribution. To compensate for the fact that information production arises naturally from the predictor dynamic (i.e., expected beliefs change) we modify the Fisher–Rao metric to account just for information generated by the control signal. The resulting optimal control problem produces non-geodesic paths through distribution space that are compared to the geodesic paths found using the standard free entropy minimizing Fisher metric in several example belief models: a Kalman Filter, a Boltzmann distribution and a joint Kalman/Boltzmann belief system.

Digital visions: the experience of self and others in the age of the digital revolution

The digital technological revolution shifted the balance of world perceptual experience, increasing exposure to digital content, introducing a new quality to our perceptual experiences. Embodied cognition offers an ideal vantage point to study how digital technologies impact on selves and their social relations for at least two reasons: first, because of the bodily performative character of the relations and interactions these new media evoke; second, because similar brain-body mechanisms ground our relations with both the physical world and its digital mediations. A closer look is taken at the possible effects of digitization on social communication, on politics, as well as on the constitution of the self and its world relations, especially in the context of the ever-increasing amount of time spent online, with a focus on digital natives. As we explore the complexities of the digital age, it is imperative to critically examine the role of digital technologies in shaping social life and political discourse. By understanding the interplay between content, emotional context, delivery methods, and shareability within digital media landscapes, we can develop strategies to mitigate the negative effects of misinformation and promote informed decision-making in our increasingly digital world.

False memories in forensic psychology: do cognition and brain activity tell the same story?

One of the most important problems in forensic psychology is the impossibility of reliably discriminating between true and false memories when the only prosecution evidence comes from the memory of a witness or a victim. Unfortunately, both children and adults can be persuaded that they have been victims of past criminal acts, usually of a sexual nature. In adults, suggestion often occurs in the context of suggestive therapies based on the belief that traumatic events are repressed, while children come to believe and report events that never occurred as a result of repeated suggestive questioning. Cognitive Researchers have designed false memory paradigms (i.e., misinformation effect, Deese-Roediger-McDermott paradigm, event implantation paradigm) to first form false memories and then determine whether it is possible to reliably differentiate between false and true memories. In the present study, we review the contribution of cognitive research to the formation of false memories and the neuropsychological approaches aimed to discriminate between true and false memories. Based on these results, we analyze the applicability of the cognitive and neuropsychological evidence to the forensic setting.

Toolbox of individual-level interventions against online misinformation.

The spread of misinformation through media and social networks threatens many aspects of society, including public health and the state of democracies. One approach to mitigating the effect of misinformation focuses on individual-level interventions, equipping policymakers and the public with essential tools to curb the spread and influence of falsehoods. Here we introduce a toolbox of individual-level interventions for reducing harm from online misinformation. Comprising an up-to-date account of interventions featured in 81 scientific papers from across the globe, the toolbox provides both a conceptual overview of nine main types of interventions, including their target, scope and examples, and a summary of the empirical evidence supporting the interventions, including the methods and experimental paradigms used to test them. The nine types of interventions covered are accuracy prompts, debunking and rebuttals, friction, inoculation, lateral reading and verification strategies, media-literacy tips, social norms, source-credibility labels, and warning and fact-checking labels.

Teaching Evidence-Based Practice Competencies to Meet Professional Practice Needs.

Evidence-based practice (EBP) is a major concept threaded throughout nursing education, yet competencies are not clearly identified in The Essentials. Nurse leaders'EBP competency expectations for professional practice were explored to inform competency-based education for students and practicing nurses. A secondary aim explored potential effects of misinformation on EBP. Descriptive qualitative inquiry was performed with a focus group of 6 clinical nurse leaders. EBP expectations were identified, discriminating between novice entry level and advanced-level nurses. Participants emphasized asking questions, linking evidence to practice, and acknowledging that evidence changes over time. All advanced-level nurses were expected to apply, lead, and teach EBP. Post pandemic, nurses need to reclaim evidence-based practices, critically appraise evidence, and educate patients and families to address misinformation. Information learned will inform competency-based EBP education for students and nurses in academic and clinical settings.

Do cognitive abilities reduce eyewitness susceptibility to the misinformation effect? A systematic review.

The fact that memories can be distorted by post-event misinformation has cast considerable doubt over the dependability of eyewitness evidence in legal contexts. However, despite its adverse practical implications, the misinformation effect is likely an unavoidable distortion stemming from the reconstructive nature of episodic memory. Certain cognitive abilities have been reported to offer protection against misinformation, suggesting that mechanisms aside from episodic memory may also be underpinning this type of memory distortion. The purpose of this review was to collate findings of associations between eyewitness misinformation susceptibility and individual differences in cognitive ability in adults aged 18 and over. Nine studies met the eligibility criteria for this review, including 23 distinct associations. Using a narrative synthesis, three categories of cognitive ability were identified as influencing susceptibility to misinformation: general intelligence and reasoning, perceptual abilities, and memory abilities. Across almost all categories, higher levels of ability were associated with reduced susceptibility to misinformation. While there is no indication that any one trait provides total immunity to the misinformation effect, there is a reasonable amount of evidence to suggest that several cognitive abilities create variance in individual levels of susceptibility. Future research should investigate not only if but how these cognitive abilities protect against misinformation distortions, for example, by contributing to more detailed encoding of the memory, enhancing discrepancy detection in the face of post-event misinformation, or improving source-monitoring during an eyewitness memory test.

Double misinformation and eyewitness performance: An experimental replication

AbstractEyewitnesses may be exposed to multiple pieces of misinformation concerning the same original detail. The two misleading details contradicting each other enable detecting a discrepancy between them, which, given that only one of them can be true, should reduce credibility of the misinformation source(s) and improve reporting. This, however, can only happen at sufficiently high levels of misinformation availability (i.e., encoding of misinformation and its subsequent accessibility): with low misinformation availability, double misinformation should instead increase the misinformation effect, providing multiple chances of yielding to misinformation. To test these predictions, we experimentally manipulated misinformation availability (high vs. low) and presented double or single misinformation. However, double versus single misinformation presentation did not affect performance or interact with misinformation availability and participants frequently reported misinformation while fully detecting discrepancies between items. Therefore, discrepancy detection alone may not be sufficient in reducing the misinformation effect, with various decision‐making processes involved in reporting.

Reading Medium and Epistemic Emotions in the Continued Influence Effect of Misinformation

It is well known that misinformation’s effects on memory linger, referred to as the continued influence effect, even after reading corrections. However, it is uncertain how the reading medium and epistemic emotions (relevant to knowledge construction) relate to the continued influence effect. In this study, college students (N = 84) read about fictional news events, each with the first article stating misinformation and the second providing corrected updated information and then indicated their emotions experienced. This was a within-subjects experiment in that two events were read on paper and two on screen to compare effects of reading medium. There were no reliable differences in the continued misinformation effect by reading medium. However, the associations between epistemic emotions and misinformation ratings appeared to be more robust when reading from paper than screens. There were no reliable differences in epistemic emotions experienced by reading medium. The findings indicate that reading news online does not appear to relate to susceptibility of misinformation.

Gaming with health misinformation: a social capital-based study of corrective information sharing factors in social media.

Correction is an important tool to reduce the negative impact of health misinformation on social media. In the era of "I share, therefore I am" social media, users actively share corrective information to achieve the "anti-convincing" effect of health misinformation. Focusing on the local Chinese context, this study constructs a structural equation model using social capital as a mediating variable to explore whether usage of Chinese users' social media can promote corrective information sharing by influencing the structural, cognitive, and relational dimensions of social capital and the role of health literacy in corrective information sharing. It was found that social media use did not significantly affect corrective information share willingness but significantly influenced share willingness through social interaction connections, trust, and shared experiences, and share willingness significantly influenced sharing behavior. The moderating effect showed that health literacy played a significant moderating effect in the influence of corrective information share willingness on sharing behavior. This study introduces the three dimensions of social capital at the theoretical level and finds that users will share corrective information for the purpose of social capital accumulation. It also provides empirical evidence for specific practices, including improving users' health literacy and actively mobilizing them to participate in the blocking and management of health misinformation in social media.

Managing the oil market under misinformation: A reasonable quest?

We examine the type and quality of information OPEC needs to successfully stabilize the oil market. Our analysis considers the impact of observational errors regarding market shocks as well as erroneous judgments of demand and supply elasticities. Actual prices resulting from OPEC's historical efforts to dampen volatility are compared to counterfactual prices that would have prevailed had OPEC remained passive. Despite the potentially confounding effect of misinformation, the elevated counterfactuals indicate that OPEC has managed to substantially decrease price volatility. Indeed, during the 2017–2021 OPEC+ period we estimate price volatility would have been up to 100% greater than actual without the actions of OPEC and its allies.

Code of silence: cyber security strategies for combating deepfake disinformation

At a time when deepfake technology is extensively employed, this study explores the serious problems produced by deepfake misinformation and recommends a comprehensive cyber security architecture to lessen its effects. Deepfakes are a serious threat to the authenticity of digital information because they use sophisticated artificial intelligence algorithms that have outlived their original novelty. This study examines the psychological effects of manipulated media, sheds light on the intricacies of creating deepfakes, and examines actual incidents that highlight the pervasive effects of deepfake misinformation. Our suggested cyber security plans include cutting-edge detection algorithms, blockchain technologies and extensive outreach programmes. Through promoting a shared dedication to openness and truth, symbolised by the figurative ‘code of silence’, this study seeks to strengthen the digital environment against the ubiquitous impact of misleading content, thereby adding to the larger conversation about preserving authenticity and trust in an increasingly digital age.

Does presenting perpetrator and innocent suspect faces from different facial angles influence the susceptibility of eyewitness memory? An investigation into the misinformation effect and eyewitness misidentification.

This study investigated the effects of face angle congruency across stages of a misinformation paradigm on lineup discrimination accuracy. In a between-subjects design, participants viewed a mock crime with the perpetrator's face from the front or profile angle. They then read a news report featuring an innocent suspect's image from the same or different angle as the perpetrator had been shown. A subsequent lineup manipulated perpetrator presence and viewing angle of the lineup members, who were all shown either from the front or in profile. No significant difference emerged in identification errors based on angle congruency between stages. However, accuracy was higher when faces were shown from the front angle, both during the initial event and the lineup, compared to the profile angle. The results of this research underscore the importance of considering viewing angles in the construction of lineups.

Risk factors related to the SARS-CoV-2 vaccine additional doses hesitancy among pregnant and non-pregnant people of reproductive age and partners: A Brazilian cross-sectional study.

The aim of this study was to assess the predictors of acceptance and hesitancy of additional doses of any SARS-CoV-2 (COVID-19) vaccine among pregnant or recently pregnant and non-pregnant people of reproductive age and partners in Brazil. We conducted an online cross-sectional study from June 2022 to April 2023 and invited women and partners between 18 and 49 years old to participate. We employed a snowball strategy to reach all potential eligible participants. Our primary outcome was the acceptance rate of the COVID-19 booster vaccine. We estimated the frequency and percentage for the three groups and compared categorical variables using the Chi-square test. Moreover, bivariate, backward stepwise regression, and subgroup analyses were performed to evaluate risk factors and predictors of COVID-19 vaccine booster hesitancy. We reported the effect size as OR with a 95% CI. We included 1487 participants, and among them, 334 (22.5%) were pregnant or recently pregnant people, 905 (60.8%) were non-pregnant people, and 247 (16.6%) were male partners. Pregnant and recently pregnant people showed greater hesitancy for the COVID-19 vaccine booster than non-pregnant people (28% vs 15%, P < 0.001) and male partners (28% vs 16%, P < 0.001). Non-pregnant women accepted the COVID-19 vaccine more often than pregnant or recently pregnant people (OR 1.75; 95% CI: 1.13-2.70). The associated factors to the reduced COVID-19 vaccine booster acceptance were family income between US$ 566-945.00 (54%), evangelic religion (65%), concern about vaccine safety (80%) and perceived common vaccine importance (93%). Pregnant people were more hesitant than non-pregnant people to accept the COVID-19 booster vaccine. Family income, religious beliefs, vaccine safety concerns, and perceived common vaccine importance were significant barriers to accepting COVID-19 booster vaccines. The impact of these factors was more evident among pregnant or recently pregnant people, emphasizing the harmful effect of misinformation among this vulnerable population.
