A separate study of the different behavioral biases does not allow for a full understanding of the complexity and stability of the heterogeneity of beliefs. Therefore, through a more global view of these anomalies, the authors wish to show that they can converge on a single concept, which is the heterogeneity of beliefs.

It is therefore essential to stress that the importance of this study is mainly reflected in the methodological approach used in the construction and analysis of the map and not only in the results achieved. This contribution states that structural analysis, as a means of building the cognitive map, can facilitate the task of investors and other decision-makers, in the identification and analysis of the heterogeneity of beliefs that can therefore guide investors' strategy in decision-making.

The authors have studied the behavior of the investor and its way of interpreting the information and the authors have emphasized the value of studying the concept of heterogeneity of beliefs in its complexity. So that part of the work seems to be relevant and crucial to filling, if you will, that void. In this sense, the authors have shown that behavioral abnormalities are multidimensional concepts: “self-deception”, “cognitive bias”, “emotional bias” and “social bias”.

In particular, this article will aim to achieve the objective of proposing a model for measuring the heterogeneity of beliefs. Thus, the authors want to show that the heterogeneity of beliefs can be measured directly through the different behavioral anomalies.

This study aims to determine the effect of cognitive biases, that is, anchoring effect, illusion of control, and endowment effect, on customer satisfaction.

An experimental design was applied using 524 undergraduate students as participants. A three-way ANOVA was employed for data analysis.

Positive relationships were found between cognitive biases and customer satisfaction. However, no such relationships were found between the interactions of various types of cognitive bias and customer satisfaction, except the interaction between illusion of control and endowment effect.

This study focuses only on three types of cognitive biases; thus, it cannot be generalized to other such systematic patterns.

Marketers can introduce cognitive bias when implementing marketing campaigns to boost customer satisfaction.

This study expands the knowledge boundary by addressing the impact of the interaction between various aspects of cognitive bias that drive customer satisfaction.

The purpose of this paper is to scrutinise the effectiveness of four derivative exchanges’ enforcement efforts since 2007. These exchanges include the Commodity Exchange Inc. and ICE Futures US from the United States and ICE Futures Europe and the London Metal Exchange from the UK.

The paper examines 799 enforcement notices published by four exchanges through a behavioural science lens: HUMANS conceived by Hunt (2023) in Humanizing Rules: Bringing Behavioural Science to Ethics and Compliance.

The paper finds the effectiveness of the exchanges’ enforcement efforts to be a mixed picture as financial markets transition from the digital to artificial intelligence era. Humans remain a key cog in the wheel of market participants’ trading operations, albeit their roles have changed. Despite this, some elements of exchanges’ enforcement regimes have not kept pace with the move from floor to remote trading. However, in other respects, their efforts are or should be, effective, at least in behavioural terms.

The paper’s findings are arguably limited to exchanges based in Anglophone jurisdictions. The information published by the exchanges is variable, making “like-for-like” comparisons difficult in some areas.

The paper makes several recommendations that, if adopted, could help exchanges to increase the potency of their enforcement programmes.

A key aim of the paper is to shift the lens through which the debate concerning the efficacy of exchange-level oversight is conducted. Hitherto, a legal lens has been used, whereas this paper uses a behavioural lens.

The study explored various dimensions of overconfidence bias (OB) among retail investors in Indian financial markets. Further, these dimensions were validated through formative assessments for OB.

The study applied exploratory factor analysis (EFA) to 764 respondents to explore dimensions of OB. These were validated with formative assessments on 489 respondents by the partial least square path modeling (PLS-PM) approach in SmartPLS 4.0 software.

The major findings of EFA explored four dimensions for OB, i.e. accuracy, perceived control, positive illusions and past investment success. The formative assessments revealed that positive illusions followed by past investment success among retail investors played an instrumental role in orchestrating the OBs that affect investment decisions in financial markets.

The formative index of OB has several practical implications for registered financial and investment advisors, bank advisors, business media companies and portfolio managers, besides individual investors in the domain of behavioral finance.

This research provides a novel approach to provide a formative index of OB with four dimensions. This formative index can acts as an overview for upcoming researchers to investigate the OB of retail individual investors.

1. Overconfidence bias is an important predictor of retail investors' behavior

2. Formative dimensions of the overconfidence bias index.

3. Accuracy, perceived control, positive illusions and past investment success are important dimensions of overconfidence bias.

4. Modern portfolio theory and illusion of control theory support this study.

The broader analytical framing of systematically distorted communication (SDC) helps extract value out of the enormous amount of scholarship on fake news.

The massive literature on fake news has been the subject of handbook overviews, systematic literature reviews, summaries, taxonomies, citation studies and so on. Deploying these tools, the approaches that the literature takes can be characterized, Habermas' concept of systematically distorted communication (SDC) will then be presented in its context, reviewed and put to work to frame fake news research to tell us new things that individual pieces of specific analysis and research do not. Conclusions will be offered from this analysis.

Fake news research has become repetitive, revolving around themes such as the fate of journalism, the role of technology, remediating its effects and deep dives into definitional components (disinformation, misinformation, lies and so on). A broader framing of systematically distorted communication allows us to arrive at some conclusions about contemporary fake news: that it is a power strategy with a particular right-wing slant and it creates a sociology – that is, its own interpretive environment – hostile to democratic functioning. It answers the question: what is fake news for?

A perspective on fake news research is much needed and Habermas' concept is a useful framing mechanism for the large corpus of research. Systematically distorted communication asks – and answers – different questions of the research. Meanwhile, SDC itself is modified by its application to fake news research and contemporary conditions.

This paper highlights an assignment in a combination upper-division undergraduate and graduate civic leadership class at a Midwestern state comprehensive university. The three-part assignment challenges students’ critical thinking skills and research capabilities while simultaneously necessitating the exploration of contrasting viewpoints on contentious issues.

Intentionally exposing students to diverse perspectives in a controlled environment.

We posit that the severity and frequency of these issues can be mitigated through focused efforts.

Students are better prepared to engage in civil debate on controversial topics, which continuously divide our communities, after completing a class using this pedagogical strategy.
