Purpose: The main purpose of the study is to assess the contributions of various research components such as authors, articles, and journals etc. and the relationship between them in the research field of behavioural biases. It also seeks to understand the conceptual framework and recognize potential future research directions. Design/ Methodology: A final dataset of 501 articles extracted from the SCOPUS database analyzed in the study. By using Biblioshiny and VOSviewer, performance analysis and network analysis techniques have employed, to assess contributions and to visualize concepts and highlight potential future research directions in the field of behavioral biases. Findings: Performance analysis reveals annual publication patterns, prominent authors, main affiliations, significant articles, leading journals, and top countries in behavioral biases research. Network analysis identifies four main themes, while co-word analysis recognizes future research prospects in the domain. Originality: The present study provides novel insights by mapping existing literature in the field of behavioral biases and offering new perspectives on its dynamics and implications. Research limitations and Future Direction – The limitation of the study is that the authors utilized only one database i.e. SCOPUS database, to regulate the outcome. Future research can be conducted using different or multiple databases. Practical Implications: The present study makes a significant contribution for individuals, the corporate sector and government regulators.
In the 1980s, a new approach called behavioural finance was introduced that combined psychology and finance. Generally, the behaviour of investors is characterized by a tendency to be influenced by various psychological factors such as human attitudes, emotions and biases which deviates them from making logical or rational decisions (Kapoor and Prosad, 2017). Behavioural finance includes the study of these psychological factors to comprehend the concept of irrationality in investor’s choices (Jain et al., 2020; Mushinada, 2020). Behavioral finance is defined by Yoong and Ferreira (2013) as the study of the engagement of investor behavior through psychological and emotional causes. It mainly concerns with the effect of emotional errors as well as cognitive biases on investment decisions. (Kahneman and Tversky, 1979; Kishor, 2020). By becoming aware of these biases, investors could better manage the risks associated with their investment choices, which could result in increased returns on their investments. (Waweru et al., 2008, Agarwal et al., 2016).
According to Dhingra et al., 2024 the conventional theories explain two main ideas: market efficiency and investor rationality. They declare that markets are efficient, consisting all relevant information, and investors perform rationally by making systematic decisions after critically assessing the information available in market (Muhmd and Maheran, 2009; Kumar and Goyal, 2015; Zahera and Bansal, 2018). These theories have given widespread recognition in the past by researchers to understand the behaviour of investors and its influence on the financial market but, in the present market, these theories may not explain correctly the questions concerning the issues of the unexplained growth of the stock market and its crashes as well as multiple possible elements which bring ideas that are unpredictable. (Zahera and Bansal, 2018). These theories have also disregarded the impact of human behaviour on investment decisions. (Jain et al., 2020).
In the pursuit of achieving the maximum degree of analytical accuracy in financial decision-making, it is paramount to address the limitations of traditional finance theories by incorporating some psychological and behavioral factors of the investors. (De Bondt and Thaler, 1995; Shiller, 1999). Thus, the emergence of behavioral finance as a new branch of finance which provides solutions and alternative methods to market anomalies addressing the psychological aspects of the investors.
The traditional utility theory of finance has been substituted with the Prospect theory of behavioral finance which signifies a drastic change from conventional to behavioral strategies (Kahneman and Tversky, 1979). Tversky and Kahneman (1974) claimed that psychological biases significantly influence the investment decision-making process in uncertain circumstances. The financial judgments of investors are significantly influenced by heuristics and cognitive biases, which often lead them to non-logical and non-rational choices (Niehaus and Shrider, 2014).
The study looks at the main areas and relationships between behavioral biases and investment decisions. This review study is a very important contribution to the behavioral finance research.
The main objective of the current review study is to provide answers to the following research questions:
Sections 2 to 5 of this review study has been organized in following manner:
The study of behavioral elements affecting investment decisions has been a well-known subject discussed in the research literature on behavioral biases in investment decision making. Numerous studies like Kahneman and Tversky, 1979 have identified certain common behavioral biases among investors, such as anchoring bias, availability bias, and representativeness bias, loss aversion and regret aversion, the disposition effect and home bias, as well as the overconfidence bias, heuristics, herding, and overconfidence have been labeled by Asad et al., 2018; Baker et al., 2019; Shah et al., 2018.
Wolman, 1973 described the phenomena of cognitive biases “as the preferentiality of choice” by investors. Kalra & Arora, 2012 expressed the term “biases” as analytical insights of financial market patterns. While the biases were attributed to the rigorous decision makers that all investors make in times of uncertainty (Chen et al., 2007).
The research by Kim and Nofsinger, 2008 found that investors were also affected by behavioral as well as psychological biases, in addition to the market volatility and the profit opportunities. The study of Sahi, 2017 found out that expert bias, overconfidence bias, and self-control bias were the forces that positively affected the individual investors' behavior and their satisfaction with investments. The work of Chandra and Kumar, 2012 and Pompian, 2012 suggested that the herding and heuristics were significantly the part of investment decisions. The researchers Kengatharan and Kengatharan, 2014 also supported the statement that the anchoring biases, the herding bias, and the overconfidence bias positively correlated with the investors' behavior.
In the research done by Puaschunder, 2017, it was also stated that herding and heuristic biases are the reasons for positive influence of variable stock market performances. Fang et al., 2017 and Shah et al., 2018 are relevant in this item as well. The study of Economou et al., 2011 and that of Lao & Singh, 2011 showed that the investors followed decisions of the dominant group due to the herding bias, which significantly influenced stock market investments. According to Asad et al., 2018, the impact of herding behaviour is less impactful in developed markets but the opposite remains in developing markets.
Kahneman and Tversky, 1979; Rauf et al., 2018; Parveen & Siddiqui, 2018; Shrotryia & Kalra, 2021 pointed out the anomalies existing in the stock market and the meaningless decisions made by investors. This uninformed manner of investing does not solely affect the individual people but it can also endanger the economy and financial systems of the country (Ahmad et al., 2017). Kumar and Goyal, 2015 and Costa et al., 2019 in their study, targeted only particular biases so it is significant to explore the success of and the tie-up between the articles published relating with individual's behavioral biases.
Jain et al., 2020 reviewed 212 documents taken from the Scopus database, assessing the literature on the influence of financial biases on behavior while Dhingra et al., 2024 took advantage of the WOS database for their bibliometry studies. The current study is unique in a way that it is different from the previous two studies - Jain et al. (2020) and Dhingra et al. (2024) regarding the study of both the database and the number of articles studied. Considering in totality the total articles used in the current study which were 501 are more than double that of the articles (212) of Jain et al., 2020 and the database (SCOPUS) utilized currently is different from the database (WOS) used by Dhingra et al., 2024.
Method of Analysis
Bibliometrics is the method used in the evaluation of literature, which is concerned with the identification of highly-cited publications on the subject (Sassmanns hausen and Volkmann, 2013). The method forwards objectivity in to review of related literature by considering a large number of scholarly articles methodically. The current study employs performance analysis and science mapping techniques of bibliometric analysis as illustrated in Figure 1.
Co-citation analysis helps in mapping previous research, bibliographic coupling verifies the existing trends, while co-word analysis identifies the potential future directions of the research (Donthu et al., 2021). These techniques also uncover thematic developments in the field over time. \

3.2 Data for the Study
The researchers choose to access SCOPUS database for statistical data while conducting this study because it presents an extensive collection of articles and related citations from an enormous geographical range. Initially, the database is searched by using keywords related to ‘Behavioural biases and Investment decisions”.
A total of 805 final documents were retrieved by using search string "Bias" or “Biases” or "behavioural biases" or "Cognitive Biases" or "Psychological Biases" or " Investor's Biases" and "Investment Decisions" or "Invest Behaviour" or "Investor's Behaviour" for the period of 1975-2023. The results shown that first publication related to Behavioural biases appeared in 1975. Following that, a series of inclusion and exclusion criteria was applied by the authors to select relevant publications.
First of all, screening was focused on the articles which were published within the domain of “Business or Business Finance or Management or Economics”, reducing the total number of articles to 578, as shown in figure 2. The search was then limited to include only articles and review articles, resulting in 509 documents. Further, the search was refined to include only English-language articles, bringing the count to 505, excluded 4 additional articles were excluded, Subsequently, 4 more documents, identified as book chapters and conference papers excluded. Finally, 501 articles for the period of 1975-2023 used for review in this study as shown in Table I.

Annual Publication Patterns
The number of articles published in a specific field is a representation of the growth trends of scientific research. Figure 3 shows the annual publication patterns in the field of behavioral biases research, as documented between 1975 and 2023. The integration of psychological studies into economic models by economists in the 70s led to the start of behavioral research. The most crucial research in this area started in the 1990s.
Between 1975 and 1989, there were only 2 papers published on behavioral biases. The number of publications ranged from 0 to 10 per year between 1990 and 2008, which was a small number. Beginning in 2009, the curve has become much steeper, suggesting that among scholars, there is a great deal of concern for understanding global financial crisis issues from the investor's behavioral perspective.
After 2018, the rise of publications on behavioral biases has been notable. A total of 262 articles published from 2019 to 2023 covered 50% of the articles used in this study. In 2022, a total of 59 articles were published, and in 2023, a total of 74 articles were published in the subject area, implying the growing popularity of behavioral finance.

Prominent Articles and Authors
Table V illustrates the most important articles along with their authors' names, arranged in order of their total citations. The most significant research paper in the study of biases in behavior is 'The Nature of Information and Overconfidence on Venture Capitalists' Decision Making' by Zacharakis and Shepherd (2016) which received 367 citations. In their study, they assessed the impact of overconfidence in relation to the nature of information on the decision-making of venture capitalists. The second most-cited article is the paper “Investor psychology in capital markets: evidence and policy implications’ by Daniel et al. (2002), which has 351 total citations. They conducted a study and were able to show that psychological biases influenced investor behavior which had an effect on market price. In the third position, the research paper ‘Overconfidence and trading volume’ by Glaser and Weber (2007) is the one that studied the overconfidence and its effects on trading volume. The article was cited 342 times and it is the third-most influential paper based on these citations. Zacharakis and Meyer (1998), followed by 325 citations for the article 'A Lack of Insight: Do Venture Capitalists really understand their own Decision Process?', are of 4th rank. The authors were primarily concerned with the comprehension of the venture capitalists' decision-making process. Chen et al. (2007) also investigated the investment decision-making in the study 'Trading Performance, Disposition Effect, Overconfidence, Representativeness, and Experience of Emerging Market Investors', where the authors collected data from the Chinese investors and discovered that the investment decisions of those Chinese were influenced by the overconfidence, representative, and disposition effects, which were considered the three main kinds of biases. This study ranked as the fifth most influential article with 319 citations. The top 20 most influential articles by the total number of citations are shown in Table V.

Conceptual View
The themes that arise from network analysis provide an understanding of the theoretical perspectives of behavioral biases. Co-citation analysis, bibliographic coupling, and co-word analysis as science mapping techniques assisted-reviewing-based examination of the past, present, and future of behavioral biases and investor activities. The methods used in identifying these themes include:
Co-citation analysis
Co-citation analysis is a methodology rooted in the notion that most of the articles cited by others are those that highlight the same issue (Hjørland, 2013). For this reason, two publications can be considered interrelated as long as they are present in the references of another paper. By using this technique, researchers can discover the articles that substantially contribute to the field of study as well as the clusters of related themes by examining the literature intersections obtained through co-citation.
Co-cited Authors
In a co-citation analysis network of authors, the minimum citation threshold initially was set to a default value of 20. Only 215 authors out of the 27405 authors could match this condition, so it was quite a selective process. However, because of this huge number of authors, the visualization background turned out to be very messy. Therefore, the point of the threshold increased to 50 citations, which refined the set of authors to only 45 which were spread out evenly among four clusters with 974 links and the total link strength totaling 59,875. In the case of Figure 4, the depicted co-citation network of authors was the result of VOS viewer.

Co-citation of cited References
In network analysis of co-cited references, the minimum citations of cited references are set as the default value of 20 citations. Out of 25,003 authors, only 5 references meet this threshold; of which only 4 items are connected with each other. There are 2 clusters and 4 items with 6 links and 36 total link strength in total. Sherfin has 20 links with 18 total link strength, Odean has 22 citations and total link strength of 22 while Tversky & Kahneman have 45 citations with 21 total link strength. The resulting image of co-cited references using VOSviewer has been shown in figure 5:

Bibliographic Coupling
Bibliographic coupling of documents, sources, authors, organization, and countries occurs when references from two publications are found to be common in another research paper (third one). This analysis uncovers the latest developments and emerging themes which provide a depiction of the present of a research field (Donthu et al. 2021). To spot the connection between documents, authors, organization and countries, bibliographic coupling has done and results of which are shown below.
Bibliographic Coupling of Documents
Figure 6 represented the bibliographic coupling of documents based on citation where 100 citations were set as a minimum threshold. Only 19 documents met this threshold, out of which 13 documents were interconnected. There are 4 clusters in total, cluster 1 (Red Colour) consists of Anderson (2011), Fraser (2015), Guenther (2018), and Kumar (2015). Cluster2 (in green) incorporates Forlani (2000), Murnieks (2011), Zacharakis (1998 & 2001), while cluster 3 in blue colour have 3 items i.e. Chen (2007), Glaser (2007), Pikulina (2017). The cluster in yellow Colour consists of only 2 documents namely Cao (2013) and Daniel (2002). Kumar (2015) has 147 citations with highest total link strength (41) while Zacharakis (2001) have highest citations with 26 total link strength.

Bibliographic Coupling of Authors
Figure 7 illustrated bibliographic coupling between co-authors. The threshold limit of the minimum number of documents of an author has set as 4 documents. Only 6 authors meet this criterion. There are 2 stand-alone clusters in total. The first cluster (marked with red color) included author Niladri dass, Martin frochmann, Nisha goyal, and Satish kumar. In this case, Nisha goyal and Satish kumar managed to collect 263 citations by having 4 documents and 616 total link strength; on the other hand, Niladri das has completed 4 documents with 63 citations and a total link strength of 167 & Martin frochman able to get 4 documents with 23 citations and strength of the link of 48 between total. The second cluster has only two members: Jinesh Jain with 5 documents with 150 citations and 898 total link strength and Nidhi Walia with 4 documents with 130 citations and an overall total of 891 link strength.

Bibliographic Coupling of Countries
Figure 8 exhibits three groups of countries. The first one, which is shown to be red, contains six countries: Australia, Canada, France, Germany, the Netherlands, and the United Kingdom. The second cluster, marking in green, involves five countries: China, Hong Kong, South Korea, Taiwan, and the US. The third cluster, characterized by the color blue, is represented by four countries: India, Indonesia, Malaysia, and Pakistan.
India published 79 papers, which in turn got 1,131 citations and has achieved a total of 16,548 of link strength. The USA authored 109 articles with 4,179 citations and had a link strength of 13,786. The United Kingdom had 56 papers, which was accompanied by 1,146 citations and a total link strength of 10,546. China released 40 papers with 667 citations and a link strength of 8,024, while Germany wrote 45 papers with 1,104 citations and a total link strength of 7,582.

Co-Occurrence of Author’s Keywords
In the co-word analysis, "word" is the analysis unit. It helps in the interpretation of the thematic clusters derived from the bibliographic coupling or co-citation analysis because of the similarities found in various publications (Chang et al., 2015). The technique of co-word analysis can be employed as a tool for the forecasting of the potential development of future research in the field. Initially, similar keywords have been combined in the network analysis of co-occurrence of keywords. Then, threshold value of the frequency of occurrence of keywords has been set to the default value of five. 54 keywords out of the list of 1425 keywords meet the stated criteria. However, with 54 keywords, the resulting image is very cluttered. However, setting of higher value for a minimum occurrence of keywords results in few keywords only. Therefore, the threshold limit of minimum occurrence was set at 8 keywords finally for best results which provide 26 keywords, 4 clusters, and 138 links with total link strength of 285. The resulting image of co-occurrence of keywords using VOS viewer has been shown in figure 9.

Various themes that emerged from above network map present the conceptual framework of behavioral biases as mentioned below:
Cluster 1: Behavioral Biases and Investment Decisions
Cluster 1 is shown in red color. The main author’s keywords in this cluster are “behavioural bias”, “behavioural finance”, “cognitive bias”, “home bias”, “investment decision making”, “investment decisions”, “investors” and “stock market.” Behavioural finance is a discipline to study the influence of psychology on financial decision-making and financial markets (Shefrin 1999).
Cluster 2: Behavioral Biases and Their Impact on Investor Behavior
Cluster 2 presents the various behavioural biases which influence investor’s behaviour. The main keywords in this cluster are “behavioural biases”, “decision making”, “disposition effect” “herding” “loss aversion” “overconfidence” “prospect theory” and “investor behavior”. Prospect theory explains various mental situations which influence investment decision-making such as mental accounting, loss aversion and regret aversion.
Cluster 3: The Role of Cognitive Biases and Heuristics in Investment Decisions
Cluster 3 is shown in blue colour. The main keywords in this cluster are “biases”, “cognitive biases”, “decision making”, “heuristics” and “investments”. It examines the role of heuristics and cognitive biases in investment decision making. Heuristics and cognitive biases are the two main pillars of behavioral finance.
Cluster 4: Financial Literacy and Its Relationship with Psychological Biases in Behavioral Finance
Cluster 4 is a group of concepts including keywords like "behavioral biases", "behavioral finance", "financial literacy", "investment decision" and "psychological biases". Behavioural biases exhibit a stronger relationship with financial literacy. (Gerth et al., 2021).
Findings
The present study explores the components of research such as authors, articles and journals and the relationship between them in the research field of behavioral biases through performance analysis and science mapping which are properly defined through bibliometric analysis. The current investigation results clearly support the argument that after 2018, behavioral bias publications experienced massive growth. Amity University, International Islamic University, Malaysia and Sri Aurobindo College of Commerce and Management are the leading institutions in research on behavioural biases by contributing 9 articles each. The most powerful country in this field is the USA with 1866 citations. The results section sheds light on the most productive journals in the research area as well. The leading journal namely "Qualitative Research in Financial Markets" published the maximum number of research papers (21). Upon measuring the major research paper by the number of citations, 'The Nature of Information and Overconfidence on Venture Capitalists' Decision Making' by Zacharakis and Shepherd (2016) is confirmed to be the one most cited, having a total of 367 citations.
A co-word analysis examined 26 keywords within 4 clusters. The keyword co-citation analysis identified four main themes. They are: investment decisions accompanied by behavioral biases, the impact of behavioral biases on investor behavior, the role of biases and heuristics, and the linkage between financial literacy and psychological biases. The application of these techniques offered a better way to understand the information regarding this domain.
In the last several years, the research on behavioral biases became a specific source of explaining the behavior of investors and the anomalies of the financial market. This literature review enhances the existing literature on behavioral biases and investment decisions via a bibliometric analysis. This bibliometric analysis brings to light the rapid development and significance of behavioral finance research. It identifies significant publications, authors, and partnerships while signaling the growing interdisciplinary avenues. This research lays out a route for future research that highlights too little studied aspects and practical uses, providing a handy reference for the advancement of the subject area.
Future Prospectus
Authors utilized data up to 2023 and exclusively from only one database i.e. SCOPUS database to regulate the outcome. In the forthcoming times, research can be undertaken by employing multiple databases and including articles that are published in 2024 onwards for a more in-depth analysis. Future research can also be conducted by using combination of two or more review methodology for better understanding and a more detailed study.
Practical Implications
The study contributes valuable insights to the field of behavioral finance and has far-reaching implications for individuals, businesses, and government regulators. By recognizing cognitive errors and emotional effects, investors are enabled to adopt more rational decision-making processes resulting in trouble-free risk management and effective strategy implementation. Companies can offer personalized advice and design products that address biases. Government regulators or policymakers could draw reforms or the laws to educate investors on how to prevent hasty decisions and how to curb market turbulence. In short, recognizing the consequences of human behavior on investment decisions helps not only individuals but also the entire financial system by bringing greater stability and integrity.
