Social media has made people better informed but also easier to manipulate. By using literature review and observing social media, the authors found a problem about echo chamber effect. The purpose of this paper is to know how the echo chamber affects the people who consume political news and the role of media diversity in it.

To conduct this study, the authors used a structured questionnaire on the Qualtrics platform to collect data from 183 participants. The authors collected data using a simple random technique. This study is based on the cross-sectional survey; the data collection period is from October to November 2023. The authors used the SPSS software to analyze the relationships between the variables and test the hypothesis.

This study found that, echo chamber is not affected by media diversity. Because of increased political interest, people will be less influenced by echo chambers. In addition, demographic factors affect political interest. People use search engines and social media sites instead of political websites when it comes to the consumption of political news online. People like to communicate with individuals who hold conflicting political views.

Researchers have not yet been able to gain a clear understanding of whether users are in an echo chamber or not and how they are interacting in that environment. Research on this topic is still going on from different perspectives. This study helped to clarify whether or not more media consumption will affect echo chambers. The possibility of being trapped in an echo chamber exists whether we use a single medium or a variety of media. The novelty of this study lies in the use of the echo chamber scale to investigate a thorough understanding of this word through the use of many factors.

This paper engages multidisciplinary perspectives on truth, authority, expertise and belief to unpack and better understand the underlying epistemology and implications of the ACRL Frame “authority is constructed and contextual.”

Following an overview of the issues confronting us in a “post-truth world,” the paper reviews critiques of the ACRL Frame “authority is constructed and contextual” and examines the related concepts of truth, authority, expertise and belief from multidisciplinary perspectives.

While the Frame acknowledges the limitations and biases of current scholarly publishing and implicitly supports social justice, it runs the danger of promoting relativism and is ambiguous regarding the relationships between expertise and authority. The critical concepts of truth and belief are conspicuously absent. Engaging a critical discussion and understanding of these concepts is a valuable contribution to information literacy.

This paper offers an important and accessible analysis of the frame “authority is constructed and contextual” and its underlying concepts. It moves beyond the library literature to include multidisciplinary perspectives and will require the engagement of the wider library community to promote discussion of the underlying epistemology and links between the construction of authority and truth, expertise and belief. In particular, the discussion of the construction of belief and the difference between judgments of fact and judgments of value offers important additions to the library literature.

Purveyors of fake news perpetuate information that can harm society, including businesses. Social media's reach quickly amplifies distortions of fake news. Research has not yet fully explored the mechanisms of such adversarial behavior or the adversarial techniques of machine learning that might be deployed to detect fake news. Debiasing techniques are also explored to combat against the generation of fake news using adversarial data. The purpose of this paper is to present the challenges and opportunities in fake news detection.

First, this paper provides an overview of adversarial behaviors and current machine learning techniques. Next, it describes the use of long short-term memory (LSTM) to identify fake news in a corpus of articles. Finally, it presents the novel adversarial behavior approach to protect targeted business datasets from attacks.

This research highlights the need for a corpus of fake news that can be used to evaluate classification methods. Adversarial debiasing using IBM's Artificial Intelligence Fairness 360 (AIF360) toolkit can improve the disparate impact of unfavorable characteristics of a dataset. Debiasing also demonstrates significant potential to reduce fake news generation based on the inherent bias in the data. These findings provide avenues for further research on adversarial collaboration and robust information systems.

Adversarial debiasing of datasets demonstrates that by reducing bias related to protected attributes, such as sex, race and age, businesses can reduce the potential of exploitation to generate fake news through adversarial data.

This study aims to examine how digital literacy competency can mitigate misinformation in social media among young adults. In recent years, concerns over misinformation have triggered a renewed interest in the aspect of digital literacy. Many young adults in Malaysia are not able to differentiate between real news and fake news. Although there are plenty of studies examining fake news, studies examining the mitigation of misinformation through the lens of digital literacy are still rudimentary.

This research adopted a quantitative approach by conducting a cross-sectional survey among university students in Malaysia to examine how their digital literacy competency influences misinformation. The sample size was estimated GPower software. A total of 134 respondents between the age of 19 and 25 were sampled because young adults in this age group tend to show little difference in their digital literacy level. Structural equation modelling (SEM) was used to examine the proposed model.

The study results reveal that two of the three domains of digital literacy competence, technical literacy and cognitive literacy, have a positive association in reducing misinformation among university students; however, socio-emotional literacy has the opposite effect. Additionally, the survey also explicates that hedonic motivation helps in misinformation mitigation, whereas habit does not.

Theoretically, this study contributes to the literature by revealing how digital literacy can help in identifying misinformation masquerading as valid information through proper verification and analysis, especially in the digital age where everyone is susceptible to misinformation. The results of the study also contribute to the development of a new digital literacy framework that can cultivate a digitally literate generation who can navigate the informational landscape smartly and therefore distinguish between facts and fake news.
