A worldwide itinerary of research ethics in science for a better social responsibility and justice: a bibliometric analysis and review

Abstract

This study provides a comprehensive overview of research ethics in science using an approach that combine bibliometric analysis and systematic review. The importance of ethical conduct in scientific research to maintain integrity, credibility, and societal relevance has been highlighted. The findings revealed a growing awareness of ethical issues, as evidenced by the development of numerous guidelines, codes of conduct, and oversight institutions. However, significant challenges persist, including the lack of standardized approaches for detecting misconduct, limited understanding of the factors contributing to unethical behavior, and unclear definitions of ethical violations. To address these issues, this study recommends promoting transparency and data sharing, enhancing education, and training programs, establishing robust mechanisms to identify and address misconduct, and encouraging collaborative research and open science practices. This study emphasizes the need for a collaborative approach to restore public confidence in science, protect its positive impact, and effectively address global challenges, while upholding the principles of social responsibility and justice. This comprehensive approach is crucial for maintaining research credibility, conserving resources, and safeguarding both the research participants and the public.

1 Introduction

1.1 Importance of research ethics and main focal points

Research ethics in science are important for the quality of scientific production. This significantly affects the integrity, credibility, and societal importance of scientific research, academic projects, and innovation (Armond et al., 2021). As more scholars explore different fields of study, the importance of maintaining ethical principles becomes paramount, not only for the advancement of scientific knowledge (Ambroz and Bukovec, 2015), but also for the establishment of social responsibility and social justice (Martínez-Valdivia et al., 2020) in many countries.

Research ethics focuses on guaranteeing research integrity, honesty, and responsibility (Lau, 2021). Informed consent, data manipulation, plagiarism, and conflicts of interest are ethical issues. Unethical practices can damage research reliability and public trust in science, and harm individuals or communities (Sivasubramaniam et al., 2021). Adhering to rigorous research ethics is essential for preserving scientific and social responsibilities.

1.2 Origin of the problem and urgency of addressing it

The origin of this problem can be traced to several factors. The “publish or perish” culture in academia can create intense competition among researchers to quickly produce significant results (Amutuhaire, 2022; Becker and Lukka, 2022). This pressure may lead to unethical practices such as data manipulation or selective reporting to present more favorable outcomes. Financial incentives are another important factor to consider. Research funding and financial rewards associated with successful publications can create conflicts of interest, influencing researchers to prioritize certain results over others, or engage in questionable research practices (Ghose et al., 2021; Jay et al., 2019; Seifert et al., 2023). Occasionally, a lack of training is the main ethical problem in research. Some researchers may not receive adequate training or education in research ethics, leading to an unawareness or misunderstanding of the ethical principles and guidelines guidelines (Wilson et al., 2018; Yeoh et al., 2017). Faced with this worrying situation, it is crucial to examine the factors contributing to the crisis and to explore potential solutions to strengthen the reliability of scientific research.

There has been a replication crisis in many disciplines. The growing concern about the inability to replicate many scientific studies has shed light on issues of research misconduct, inadequate methodology, and publication bias, raising questions regarding the reliability of research findings (Boulesteix et al., 2020; Cantley, 2023; Cooper, 2018; Hope et al., 2021; Ryan and Tipu, 2022).

It has also been proven (Sorokowski et al., 2019) that one of the most significant problems faced by modern scientific publishing systems is the pressure to publish positive results, which is a major drawback. In some cases, institutions or journals may have insufficient oversight to detect and address unethical behavior (Bain et al., 2018; Malviya, 2012; Resnik, 2023; Thorogood and Knoppers, 2017), allowing misconduct to go unnoticed or unpunished. According to some authors, the main factors explaining the lack of research ethics are related to data sharing and transparency. Beyond these factors, the emergence of new ethical challenges in emerging fields could be problematic. Fields such as human resources (Edwards et al., 2022), artificial intelligence (de Zárate Alcarazo, 2022), and Tissue Engineering (TE) for Regenerative Medicine (RM) (De Kanter et al., 2023) may present new ethical dilemmas that researchers and regulators may find difficult to resolve.

1.3 Strategies and solutions for addressing research ethics challenges

To solve these problems and overcome the challenges of research ethics, scientists have established rigorous peer review processes to evaluate research proposals and publications (Malviya, 2012), create and share ethical codes and guidelines for reference (Santos et al., 2017), promote transparency and data sharing to prevent data manipulation and facilitate replication (Boulesteix et al., 2020; Hassan et al., 2022), obtain informed consent and ethical approval to protect research participants (Afolabi, 2012; Moore and Savage, 2002), and provide education and training programs to promote academic integrity and ethical behavior. It also established mechanisms to identify and address research misconduct, such as plagiarism and fabrication (Agrahari and Sharma, 2017; Langlais, 2006; Laskar, 2017; Mohammed and Abdelsalam, 2022; Reisig et al., 2020), and encouraged collaborative research and interdisciplinary partnerships (Fairhall et al., 2016; Nyström et al., 2018) to bring diverse views, reduce ethical bloodspots, and practice open science to encourage reproducibility and transparency (Wolfram et al., 2020), among other steps. Additionally, reporting negative or inconclusive results prevents publication bias (Van Aert and Niemeyer, 2022; Lin and Chu, 2018) and creates balanced scientific literature. Leadership and institutional commitment to research integrity are essential for prioritizing and rewarding ethical conduct.

The urgency of addressing the research ethics issue lies in its potential consequences, including misdirection of policymakers, hindrance of scientific progress, and waste of resources. Such misconduct also harms public trust in science and can endanger society's wellbeing (Goldenberg, 2022; Huber et al., 2019; Intemann, 2023). Immediate action is necessary to maintain research credibility, conserve resources, and safeguard both the research participants and the public. A collaborative approach is crucial for restoring confidence in science, protecting its positive impact, and addressing global challenges.

1.4. Current gaps and new challenges in bibliometric analysis and systematic review

The current state of knowledge regarding research ethics in scientific publications shows a considerable awareness of the major role of ethical conduct in the research process (Tormo-Carbó et al., 2018). Numerous institutions, guidelines, and codes of conduct have been developed to address the ethical concerns in various research domains (Franzke, 2022; Larsson, 2020; Laws and Utne, 2019).

However, several gaps and shortcomings remain unaddressed. Methodologically, there is a lack of standardized and comprehensive approaches for detecting research misconduct (Girgin et al., 2022; Hawkins et al., 2018; Matosas-López and Cuevas-Molano, 2022), leading to difficulties in identifying and preventing unethical behavior. Theoretical gaps exist in understanding the underlying factors that contribute to research misconduct (Dal-Ré et al., 2020; Golden et al., 2023; Haven and van Woudenberg, 2021; Horbach et al., 2020; Rodrigues et al., 2023) and how to foster a culture of research integrity effectively. Conceptually, there is a need for clearer definitions and classifications of the different types of research ethics violations to facilitate better reporting and analysis (Shaw, 2019). Contextually, challenges arise from the evolving landscape of research, such as emerging fields and the influence of technology, which may create new ethical dilemmas that are not adequately addressed in the existing guidelines (de Zárate Alcarazo, 2022; Edwards et al., 2022; De Kanter et al., 2023). Moreover, the universal enforcement of research ethics guidelines is lacking, leading to inconsistent practices and accountability across research communities and institutions (Ataullahjan et al., 2022; Mills et al., 2020). Ethical considerations in interdisciplinary research and cross-cultural studies require more attention to ensure that ethical principles are applied appropriately across diverse contexts (Bonde et al., 2016; Kwame and Petrucka, 2023; Quester and Simpson, 1998; Rawwas et al., 2005). Furthermore, there is a need to promote open science practices and data sharing to enhance research transparency and to reduce the risk of publication bias (Wolfram et al., 2020). Addressing these gaps requires collaborative efforts from researchers, institutions, policymakers, and funding agencies to strengthen the foundation of research ethics, foster a culture of integrity, and uphold responsible conduct within scientific communities.

Previous bibliometric analyses and systematic reviews on research ethics in scientific publications have revealed several inadequacies. They often focus on narrow subfields, which leads to a limited perspective. Incomplete data coverage and inadequate contextual information have hindered a comprehensive understanding. Overreliance on quantitative metrics has overlooked the qualitative aspects of the ethical challenges. However, emerging ethical issues and cultural contexts have not been explored sufficiently. Neglecting open science practices has hindered holistic assessment of research integrity. Addressing these limitations is crucial for a more robust understanding of research ethics and fostering responsible scientific practices. To overcome these limitations, this study aims to emphasize social responsibility and justice in the application of research ethics principles across various fields of specialization. This study was structured to address the following research questions:

• - How is the evidence base distributed concerning the total number of scientific documents, their research fields, annual production by subject area, and the most relevant authors by subject area?

• - How do you explain the emergence of these themes in a particular field?

• - Why are ethics and social responsibility more widely debated in some disciplines than in others?

• - What explains the profusion of the debate on research ethics in some countries but not in others?

To enhance the systematic management of the literature corpus, this study restricted the bibliographic search to the Scopus database. The resultant dataset was exported in the CSV format to facilitate subsequent data processing and analysis procedures.

2 Research methodology

2.1 Research design, data collection, and search strategies

As a mixed article, this study utilized Bibliometrix R, a potent programming language for statistical analysis and data visualization, to conduct a bibliometric analysis. Bibliometrix offers a comprehensive set of functions to analyse, visualize, and explore vast bibliographic data, including descriptive statistics, co-authorship network analysis, keyword analysis, and citation analysis. This provides valuable insights into the patterns and trends within their research domains. To show the actual state of the research ethics debate in various fields and its gaps, this research applied the Problem, Intervention and Outcomes (PIO) approach for a short systematic review. Literature recommends the application of formal processes such as the PICO model (Problem, Intervention, Comparator and Outcomes) to carry out systematic reviews and maps to effectively synthesize behavioral (Berger-Tal et al., 2019; Considine et al., 2017; Pollock and Berge, 2018; Verschuren and Doorewaard, 2010). The PIO method is a variant of PICO that does not consider the comparator and has been used in several studies.

P: Research studies focusing on research ethics, frameworks, or principles applied in various scientific or societal contexts.

I: Application, utilization, or adherence to ethical principles, research integrity, or methodologies aligned with ethical guidelines. O: Impact on social equity, justice, sustainability, social responsibility, and inclusivity.

The applied research strings were as follows:

“Research ethics” OR “Ethical considerations” OR “Ethical principles” OR “Ethical guidelines” OR “Moral standards” OR “Research integrity” OR “Ethical framework” OR “Responsible conduct of research” OR “Ethical protocol” OR “Ethical standards” OR bioethics OR “ethics in research” OR “ethic^* in science” OR “morality in science” OR “ethic^* principles” OR “methodologic^* values” OR “virtue in research” OR “scientific^* integrity” OR “scientific conscience” OR “honesty in science”)

AND

(use OR conducting OR respect OR us^* OR utiliz^* OR employ^* OR apply^* OR applicat^* OR “Mak^* use of” OR exercis^* OR “Resort to” OR “Call upon” OR adopt^* ”” OR practic^*)

AND

(“Scientific responsibility” OR “Corporate social responsibility” OR csr OR “Ethical responsibility” OR “Social accountability” OR “Civic responsibility” OR “Community responsibility” OR sustainab^* OR “Public interest” OR “Environmental stewardship” OR “Social consciousness” OR “Community engagement” OR ”” OR “Distributive justice” OR “Economic justice” OR “Racial justice” OR “Environmental justice” OR “Gender justice” OR moral OR “Human rights” OR equity OR “Social equality” OR fairness OR inclusivity).

The document types included articles, reviews, and conference papers published in French and English.

The search for scientific publications was conducted on 27/08/2023, and the results were not updated. As final dataset, this research obtained a total of 3,128 documents published between 1965 and 2023. The metadata for each publication included citation and bibliographical information, abstracts, keywords, funding details, and other relevant information.

To ensure consistency of the data, I limited the search to English and French publications. Furthermore, I have focused on peer-reviewed journal articles, reviews, and conference papers to ensure credibility and reliability of the sources. The following section provides a detailed description of this process.

2.2 Data processing, bibliometric, and systematic analysis

The process began with the formulation of a search equation in the SCOPUS database. The application of this equation yielded an initial database of 3,615 documents. This was followed by direct screening of titles and abstracts in SCOPUS to refine the selection of relevant documents. At the end of this exercise, a database of 3,128 documents was obtained. Once this screening was completed, the data were extracted from SCOPUS, marking the end of the data collection phase. These data were then processed using two parallel approaches during the analysis phase. On the one hand, the Bibliometrix package is launched and loaded to enable general bibliometric analysis via the Biblioshiny interface. Data were imported into Microsoft Excel for comparative analysis by thematic area.

These two approaches converge in the final phase of data visualization. The process culminates in a comprehensive synthesis comprising several elements: a general overview of the literature, analysis of sources, review of key authors, study of documents, geographical mapping of research, and representation of the conceptual intellectual structure that highlights current debates and emerging lines of research.

The results are described in the form of frequency histograms, bar charts, curves, maps, and tables, which were analyzed and discussed. The journal impact factors presented in the results come from information available on journal websites in the Web of Science. They show the impact factors for each journal over the last 5 years. To highlight the current debates and gaps in the research theme, the Litmaps visualization tool was used to identify and analyse key publications. The process of data processing and bibliometric and systematic analyses are shown in Figure 1.

The keywords generated automatically by an algorithm from the reference citation in the documents slightly outnumber the authors' keywords (7,243–6,503), suggesting that they are more informative than the authors' keywords (63, 64).

The need to consider ethics throughout the scientific research process has led to several collaborative scientific contributions. This explains the average proportion of co-authors per document (3.04) and the international nature of the research teams (16.75%).

3.1.1 Distribution by main subject area

The findings showed that this collection of 3,128 documents is related to many scientific disciplines. Figure 2 shows that 28 subject areas were concerned with scientific documents related to ethics in the research. The main research areas were medicine (44.73%), nursing (13.87%), Business Management and Accounting (7.83), social sciences (7.00%), arts and humanities (6.55%), and Biochemistry Genetics and Molecular Biology (3.71%).

3.1.2 Annual production of research

3.1.2.1 Global research annual production

The progress from 1965 to 2023 in global scientific production by year is shown in Figure 3. The curve showing the evolution of scientific publications on research ethics indicates that the increase in the number of publications can be broadly divided into three periods: 1965 to 1985, 1985 to 2003, and after 2003.

Figure 3.

Annual global scientific production by year.

During the first period, from 1965 to 1985, publication activity remained consistently low, with minimal variation, and very few articles were published annually. The second period, spanning 1985 to 2003, exhibits a slight but steady increase in publication numbers, marking the beginning of a growing interest in research ethics. The third period, starting after 2003, demonstrated a marked acceleration in publication activity, characterized by a steeper upward trend. This final period is particularly notable for its huge increase in publications, culminating in significant peaks exceeding 200 articles between 2020–2023, though with noticeable fluctuations. The overall trend is captured by a regression line (y = 3.3297x – 46.874) with an R² value of 0.754, suggesting that time explains ~75.4% of the variation in publication numbers. This three-phase pattern reflects the evolving importance of research ethics in scientific discourse from a niche topic to a major concern in the scientific community. The most recent period particularly highlights contemporary emphasis on research ethics, driven by increased awareness of ethical considerations in scientific research and stricter publication requirements.

Even if Scopus was created not so far from 10 November 2004 by Elsevier, a Dutch academic publishing company, this scientific abstract and citation database covers many disciplines in a temporary coverage beginning in 1788 (Wikimedia Foundation, 2024).

3.1.2.2. Annual production of research by subject topic and the emergence of research ethics in certain fields

The annual scientific output for each specialty was similar. The three main periods were identified for overall production. The Figure 4 bellow presents the annual scientific production by year and subject area since 1965.

Figure 4.

Annual scientific production by year and subject area.

The first scientific publications dealing with research ethics were in the field of medicine and nursing (1965–1985). Since 1987, dentistry has joined other publications in the field of health science. The first work on research ethics in psychology, the humanities, and social sciences was published in 1993. The findings show that the first publication on research ethics in the Agricultural and Biological Sciences dates to 2001. The first publication in Earth and Planetary Sciences was published in 2004. In 2005, the fields of economics and finance obtained their first publications. The first publication in the field of Computer Science was in 2006.

From 2007 onwards, a wide range of new fields of knowledge began to be published on the subject of research ethics, including Environmental Science, Art and Humanities, Biochemistry Genetics and Molecular Biology, Business, Chemistry, Decision Sciences, Energy, Engineering, Health Professions, Immunology and Microbiology, Mathematics, Multidisciplinary, Neuroscience, Pharmacology Toxicology and Pharmaceutics, and Veterinary and Undefined fields.

However, the field with the most recent publications on research ethics was Materials Science in 2015.

Generally speaking, publications in medicine and nursing dominate over the period from 1965 to 2023, except in the years 2007 to 2016, when, although medicine retained the lead, publications in management and accounting outnumbered those in nursing, which was second place.

3.1.3.2 Most relevant authors by subject area

Figure 6 shows the 10 most productive authors in this field. These articles were published in various journals. Of the 97 publications, 61 were in the field of medicine, 21 in nursing, and four in Art and the Humanities; three publications were in Psychology and Biochemistry Genetics and Molecular Biology, and two in Engineering, Immunology and Microbiology. Only one document has been published in the social sciences. Each author publishes at least two specialist fields, except for Martin, who has only been published in medicine. There is a transdisciplinary approach to research ethics in the scientific literature. None of the most influential authors in this area of research are in the field of agronomic science. This finding suggests that questions related to the ethics of scientific research in this discipline are new.

3.2 Main debate topics and gaps

Scientists and professionals frequently discuss research ethics. Table 3 below presents the distribution of the dataset publications across the major topics, offering an insight into the scope and focus of the ethical debates. It highlights three main categories of topics: ethical imperatives, medical research ethics, and methodological innovation. Medical research ethics dominates scientific discourse (1,158 publications). Key areas of focus include participant safety in clinical trials (70 publications), moral dimensions of medical ethics (61 publications) with some concern about organ transplants and euthanasia and randomized clinical trials (21 publications). Methodological innovation (615 publications) prioritize debate about participatory research (122 publications and ethical responsibility (397 publications). Scientists discuss ethical imperatives (483 publications) especially related to adolescent research ethics. These topics reflect the global and complex nature of ethical challenges in science. Emerging issues such as artificial intelligence and big data also highlight the growing importance of addressing technological advancements in research ethics.

4 Discussion

The discussion of the main findings will begin with a comment on the main descriptive statistics, the place of research ethics in some fields, the actual scientific debates, and the major research gaps.

4.1 What were the main bibliometric findings?

The overall presentation of the descriptive statistics of the database created for the bibliometric analysis shows that the notable citation count of 115,700 references in the dataset and the average rate of 17.36 citations per document highlight their significance within the academic community. This substantial citation rate indicates that the topic of research ethics is widely acknowledged and has considerable influence across a diverse range of subjects and disciplines (Tahamtan et al., 2016; Zhang et al., 2021). The greater number of automatically generated keywords (7,243) than author keywords (6,503) indicates that the algorithm employed by Biblioshiny to extract keywords offers a more comprehensive understanding of the document's content (Egozi et al., 2000). This shows the potential of these automatically generated keywords to provide a more informative representation of the research topics discussed in publications and the rich collaborative approach used.

Despite the wide variety of scientific fields that deal with ethical issues, medicine and human health research are mostly permeated by ethical considerations. These findings underscore the influence of ethical considerations in human health (Artal and Rubenfeld, 2017) research and across various fields because of the social context (Madushani, 2016). This emphasizes the importance of interdisciplinary collaboration in research to address ethical challenges (Laasch et al., 2023).

The results also show that the history of research ethics is a complex and evolving journey, marked by significant incidents and milestones in 1982, 1989, 1993, 1997, 2000, 2005, 2008, 2012, 2017, and 2020. These pivotal moments have shaped the intellectual landscape of research ethics and have profoundly impacted the global scientific community. As I delve into the intricate details of each of these incidents, it becomes evident that the evolution of research ethics is intertwined with the pursuit of social responsibility and justice (Dhai, 2014; IJsselmuiden et al., 2010). Over the last few decades, there has been increasing recognition of the necessity of ethics throughout the entire research process (Benatar and Singer, 2010). The ethical principles of respect include not only the research conducted, but also the data collection, analysis, and dissemination of research findings and innovation. Worldwide recognition of the scientific community has been driven by the expansion of research into various disciplines involving human participation (de Seneviratne, 2023). The Declaration of Helsinki has undergone seven revisions to ensure that it remains relevant and, to date, in the rapidly evolving field of medical research. Revisions were made to address criticism, incorporate new ethical considerations, and adapt to advancements in science and technology. These revisions also aimed to enhance the protection of research participants, particularly vulnerable groups, and address emerging issues, such as the use of biobanks and compensation for research-related injuries. The process of revising the Declaration involved input from expert stakeholders and organizations globally, as well as careful consideration of feedback and comments from various sources (Allebeck, 2009; Malik and Foster, 2016). Outside the field of medicine, the need to follow ethical research rules highlights gender and minority disparities in scientific publication bodies in medicine, pharmacy, and nursing (Bates et al., 2016; Dorrigan et al., 2022). Furthermore, the global landscape of research ethics has evolved significantly over the years, with an increasing emphasis on cross-cultural considerations and diverse ethical perspectives that shape research practices worldwide (Honan et al., 2013). As technology and scientific collaboration continue to transcend international boundaries, there is an evident need for a more comprehensive understanding of research ethics on a global scale (Adu-Gyamfi, 2015; Marshall and Batten, 2004). The period between 1965 and 2023 witnessed significant milestones in the evolution of research ethics, including the establishment of ethical review boards, the development of international guidelines such as the Declaration of Helsinki, and the integration of ethical considerations into research funding and publication policies. These developments have underscored the importance of ethical awareness and accountability in the scientific community, serving as a driving force for continued discourse and reflection on future research ethics.

The findings of the most relevant authors reveal that they made substantial contributions to their fields. This aligns with the notion that prolific authors often possess in-depth knowledge and experience of their respective domains (Boyack et al., 2005; Leydesdorff, 2011). This shows significant engagement in research ethics, reflecting a diverse range of perspectives and methodologies. This diversity is crucial for addressing the multifaceted nature of ethical challenges in science and underscores the collaborative and interdisciplinary nature of research ethics inquiry (Alfonso et al., 2019; Beshyah et al., 2018; Smith and Williams-Jones, 2012). This collaborative approach facilitates the exchange of ideas and fosters innovation in ethical theories and practices (Moreno-Cely et al., 2021). Overall, the prominence of these authors underscores the importance of their collective efforts to advance our understanding of research ethics and to promote ethical conduct across scientific disciplines.

The diversity of disciplinary fields is also apparent in the most relevant authors on the theme of research ethics. Their publications cover a wide variety of fields, despite the predominance of medicine. The observed transdisciplinary approach underscores the collaborative nature of addressing the ethical dilemmas in research (Mertz et al., 2014; Zhang et al., 2021). Notably, the absence of influential authors from agronomic science suggests a nascent exploration of ethical considerations within this discipline, signaling an opportunity for further investigation and integration of ethical frameworks (Bawden, 2010).

A total of 1,516 scientific publications hosted the documents collected in the database. The findings suggest that the frequency of journal publications by authors is influenced more by the disciplinary orientations and subjects covered by the journals than by the impact factors of those journals. This implies that authors are driven by the relevance of the journal to their research area rather than the prestige associated with high-impact factors (Mara et al., 2016). It underscores the importance of aligning research with the thematic focus of journals, reflecting the prioritization of content over journal metrics in scholarly communication (Bavdekar and Save, 2015). This observation highlights the nuanced factors that shape publication decisions among researchers across disciplines.

Research ethics have been the subject of research by several teams worldwide. The trend observed was that most publications were products of teams from the same country. The most notable countries in terms of publication volume were the United States, the United Kingdom, Canada, the Netherlands, Italy, Germany, South Africa, and China. South Saharan African countries were poorly represented in this study. This may be because of the ethic in research topic history regarding science progress and the secund World War, its atrocities, and the weak African implication. Countries that have experienced significant research ethics violations or scandals in the past tend to have more robust debates on this subject. It is the case in European Union countries with the atrocities of the Secund World War and the first formal declaration for physicians doing research, known as the Declaration of Helsinki. This is also the case in the United States and the history of controversial experiments, such as the Tuskegee Syphilis Study (Paul, 2018). Research ethics have evolved over time in response to various historical events and ethical dilemmas faced by researchers worldwide (Laudan, 1986).

For scientists such as Patelli et al. (2017), the level of scientific and technological advancement is the most relevant criterion for progress in science. For these authors, the global south is poorly represented in global scientific development, even if some countries from the BRICS group are present (Patelli et al., 2017). Science and its Critical Inquiry are philosophically different from many cultures worldwide. Some cultures emphasize individual rights, while others consider the social group highly. In the first case, research ethics can consider informed consent and privacy in research, and the other case must prioritize the collective benefits of science (Robert Nola, 2006; Tov and Nai, 2019; Xiao, 2021). Several other factors may have influenced the few publications on research ethics and the substantial number of publications, depending on the county. Political and economic factors, funding sources, weight of international collaboration, media attention, and the institutionalization of research ethics by the existence of ethics or bioethics committees and institutions.

The discussion of the results of the bibliometric analysis opens new perspectives for understanding the findings of the short systematic review. This highlights the current debates and gaps in the knowledge about research ethics.

4.2. Emergence of ethics and social responsibility as key themes in certain disciplines and new debates

Over the years, there has been a proliferation of research ethics publications that emphasize many debate topics among scientists.

One of the oldest but still topical issues in research ethics is informed consent and anonymity of research participants (Badampudi et al., 2022; Solis Sánchez et al., 2023). This author recalls the ethical imperatives of research stemming from the atrocities perpetrated by Nazi doctors regarding concentrating camp inmates. Prior to this publication, several authors addressed various aspects of this issue. These include Joffe and Miller (2008), who believes that medical research, although oriented toward care, fundamentally has a moral dimension distinct from the latter (Arahuete and Pinazo, 2022; Grosek et al., 2023). Some authors believes that the new regulations introduced in the United States since 1996 for emergency medicine to allow research on human subjects without their informed consent have shown great limitations because of the legal consequences of such research (Carracedo et al., 2024; Fritzsche, 2024; Orievulu et al., 2024).

Along the same lines Loveday et al. (2022) illustrated the case of research on adolescents without parental consent in South Africa (Loveday et al., 2022). The case of randomized clinical trials and the problem of suboptimal care (Zhang et al., 2023), that of consent given, and its limits in the case of organ transplants with living organ donors (Raza and Neuberger, 2022). Apart from debates in medicine and health sciences in general, discussions in the scientific world are also taking place in other disciplines. This is the case, for example, with the issue of methodological innovation in the social sciences, where questions on ethical responsibility, democratization of research, empowerment, and the relationship between innovation and the world of research are all on the agenda (Bellavista et al., 2022; Druckman and Donohue, 2020; Raza and Neuberger, 2022). A reference to the cases of action research highlights that, in the case of participatory research involving young people, the cultural context and moral values oblige the researcher to reach an agreement with his participants to facilitate their involvement in the research projects (Cullen and Walsh, 2020). For example, in psychology, the subject of protecting mentally incompetent patients has been addressed (Kaur, 2011). The remuneration or compensation of research subjects also raises ethical concerns because of the risk of transforming the payment received by participants into a simple commercial exchange (Różyńska, 2022). In the field of pharmacy, the question of participant safety during clinical trials is widely debated, especially for human medication (Jedličková, 2024). Apart from the many debates on Informed Consent and Participant Autonomy, data security and privacy are also emerging topics.

Khan et al. (2022) published one of the most important publications on this subject. He proposed to reflect on the ethics of research through the mechanisms of urbanization, such as smart cities that use artificial intelligence technologies. For this author, it was necessary to set security limits for the protection of personal data and the safety and security of these cities by forging effective political and algorithmic instruments (Bibri, 2021; Khan et al., 2022; Stahl and Eke, 2024). In the same vein, authors such as Calvo (2020) believe that the impacts and consequences of digital connectivity, the use of algorithms and databases in the urban digital society, and the security dangers of connected objects require rigorous application of ethical rules (Calvo, 2020).

Allam et al. (2022) and Bibri et al. (2022) believed that science and technology are the future of human living environments. They open an epistemological debate on the relationship between science and technology, and the profound changes they can exert on societies and their structures. They concluded that it is necessary to structure metaverses as virtual worlds in a manner that is morally acceptable and culturally appropriate for cities (Allam et al., 2022; Bibri, 2023; Bibri et al., 2022). Other authors have worked on the importance of the legal regulation of the Internet (Tzafestas, 2018) and ethical guidelines for data science training courses (Bates et al., 2020). Other topics of debate include the legal and social responsibility of digital companies (Lobschat et al., 2021) and ethics in communications, especially in print media (Kojo et al., 2022).

Artificial Intelligence and Machine Learning are also a major focus of scientific publications, in line with current debates on technology (Olteanu et al., 2019), ethical rules to be developed for machine learning and big data (Ananny and Crawford, 2018; Greene et al., 2019; Jobin and Vayena, 2019; Zwitter, 2014), and the use of artificial intelligence for predictions in politics, technology, and culture (Karppi, 2018; Morley et al., 2021; Lo Piano, 2020; Wong, 2020).

Review of ethics regulations and considerations of the ethics, accountability, and responsibility of Artificial Intelligence developers and users (Koniakou, 2023; Pant et al., 2022; Vesnic-Alujevic et al., 2020).

Research methodologies and ethical requirements have always contributed to the contributions of various authors. In this context, four major subthemes are widely discussed in the literature: (i) bias and fairness in research, (ii) access to research benefits, (iii) transparency and reproducibility, and (iv) ethics in global research collaboration. Over the past 5 years, publications dealing with bias and fairness in research results have focused on tools for measuring bias in various social sciences such as psychology, education sciences, and knowledge transfer in agriculture through digitalization (Fielke et al., 2020; Tay et al., 2022; Woo et al., 2022). Debates on bias and fairness are also taking place in computer sciences, machine learning, and artificial intelligence (Booth et al., 2021; Taylor, 2017), and their use in healthcare (Saheb et al., 2021).

In terms of access to and benefits from scientific research, early data protection throughout the entire research cycle is of paramount importance (Karcher et al., 2023). For other authors, the benefits of science and access cannot be achieved without promoting open science. However, the latter needs to be framed by ethical rules (Campbell et al., 2022, 2023). Financing the costs of publishing scientific articles and the implications for researchers' home countries can act as a brake on open access and reproducible research (Brabeck, 2021; Hardwicke et al., 2020; López-Nicolás et al., 2022; McKinley Yoder et al., 2022; Nwagwu, 2023; Page et al., 2021; Sabik et al., 2021; Sandoval-Lentisco et al., 2024). Discussions are also underway on issues related to gender and sexual violence in the academic environment (Roeschley et al., 2024; Siegel et al., 2021). Other authors make a plea for a global ethical governance of society capable of breaking down the barriers between bioethics, ecology, and society for a more effective theory of work (LeBlanc, 2023).

As concerns about the transparency and reproducibility of research have already been mentioned, I will quickly highlight a few salient points about ethics in global research collaborations. Over the past 5 years, several authors have discussed the importance of ethics in scientific research collaboration. Some believe that the criteria that determine collaboration between authors often vary according to their geographical and disciplinary proximity (Hedt-Gauthier et al., 2019). Similarly, some authors believe that collaborative research facilitates trust and scientific integrity while reducing ethical misconduct among researchers and research institutions (Bouter, 2022; Kerasidou, 2019, 2021; Kerasidou et al., 2021; Soehartono et al., 2022).

All of these topics of debate about ethics in science for better social responsibility and social justice are not exhaustive, but they shape major concerns. Nevertheless, it would be interesting to understand how social ethics and responsibility seem to be better positioned in the debates of some disciplines than others.

4.3 Knowledge gaps and future research pursuits

When I consider research ethics in science for better social responsibility and justice, there are several research gaps. This lack of scientific knowledge represents an area where further research is needed to ensure that science is ethically ruled to contribute to social wellbeing. Some of these gaps are as follows.

In many societies, there is no integration of traditional and scientific knowledge mechanisms (Kleiche-Dray et al., 2012). The knowledge produced by science and that generated by social institutions, traditions, habits, and customs of non-Western societies comes from different worlds and often does not combine easily. The aim of research ethics in promoting equitable access to scientific knowledge has not been sufficiently published. The awareness of the need to make scientific knowledge more accessible to all cultures of the world at all social levels, without segregation of any kind, including strategies for open access to scientific publications and inclusive representation in research (Broggiato et al., 2014; Chan et al., 2011; Kleiche-Dray et al., 2012; Kunz, 2021; Ross-Hellauer et al., 2022). Sub-Saharan African countries are particularly affected by this gap in the integration of science with local culture and language (Abolou, 2006). This gap must be addressed by researchers and research institutions. The need to take account of the particularities of different cultural groups in different parts of the world and to make scientific research culturally sensitive is also a gap in the current knowledge about research ethics, responsibility, and social justice (Kleiche-Dray et al., 2012; Robert Nola, 2006).

With great scientific progress in data management with big data and artificial intelligence in research, there is a gap in understanding and balancing data utilization with individual privacy rights and the rights of minorities and vulnerable populations (Lacroix, 2019; Nemati, 2020). By filling this gap, the global scientific community can provide richer answers to the research validation and methodological requirements. In this respect, there is a real need for more scientific publications on how to build research methodology, positive social sustainability, and ethics, beyond the simple production of research results (Rau et al., 2018).

The results obtained earlier in this study also show that there are gaps in these disciplines. In the Humanities and Social Sciences, despite the relevance of the issue of responsibility and social justice, the quantitative lack of publications (in this database of 3,128 publications, only 219 articles come from the field of Social Sciences) on research ethics is complemented by qualitative gaps. The latter can be seen in the growing need for publications on the ethical implications of qualitative research methods (Fielke et al., 2020; Tay et al., 2022; Woo et al., 2022), power dynamics in researcher- participant relationships (Kaaristo, 2022), and the recurring question of how to consider cultural sensitivity in cross-cultural studies (Marshall and Batten, 2004; Robert Nola, 2006).

In agricultural and food sciences, beyond the large group of natural and agricultural sciences, there are glaring gaps in research on ethics. The results showed that it was only in 2001 that the first scientific publication was published in this field. The article in question is titled ‘Ethics in apiculture by Wenning, Carl, published in the American Bee Journal. In this paper, the author discusses the code of conduct followed by the beekeepers. He defends the position that all professions should respect ethical rules and that agricultural professions should be no exception to this rule (Wenning, 2001).

The relative novelty of this theme in Agronomic Sciences makes it interesting to bridge the existing gaps in the ethical implications of the exercise of professionals (Wenning, 2001) linked to animal and fish production, plant production, natural resource conservation, and so on. The limits of knowledge can also be seen in the ethical implications of the development and dissemination of agricultural innovations (e.g., digitization of agriculture, GMOs, cloning of living material), the balance between food safety and preservation of the environment, and in the ethical considerations relating to animal-based agricultural research (Adalja et al., 2023; Hassoun et al., 2023; Häyry, 2018; Pollans, 2015; Rapela, 2020).

In view of the above, future research needs to focus on ethics, social responsibility, and social justice in the agricultural sciences, particularly in countries of the south, especially in sub-Saharan Africa.

4.4 Research limits

This contribution to the debate on research ethics attempts to take an overall look at the advances and gaps in scientific production on this topic.

It is important to acknowledge the limitations inherent in relying solely on the Scopus database for this mixed bibliometric analysis and systematic review. The observed growth in global research annual production and country contributions may be partially attributed to a “database effect” rather than solely reflecting actual increases in research output. Scopus has continuously expanded its journal coverage over time, which could artificially inflate growth trends.

Furthermore, it is possible to think that the Scopus database, because it contains a large volume of English-language publications, has an intrinsic bias toward this language and therefore, in turn, produces a bias toward publications from countries with an English tradition, such as Great Britain, the United States, Canada and Australia. This tendency may skew the representation of research output from non-English speaking countries and potentially underestimate their contributions to the field.

Furthermore, the exclusive use of Scopus may overlook relevant publications in journals not indexed by this database, potentially missing important contributions to research ethics. To mitigate these limitations, future studies should consider incorporating multiple databases, such as Web of Science, Dimensions or Google Scholar, to provide a more comprehensive and balanced view of the global research ethics landscape. Additionally, efforts to include non-English publications and analyze trends in publication language and country of origin over time would help contextualize the findings and provide a more accurate representation of the field's development.

5 Conclusion

Scientific research and its importance for human beings and societies oblige research professionals to take care of and apply ethics principles. This study set out to understand how ethical principles, scientists' social responsibility, and science's necessary social justice are internalized in many scientific fields worldwide. A focus was made about this topic analyzed across a database of 3,128 scientific publications from 1965 to 2023. Based on the outcomes, ethics and its principles influence research in human health and various other fields, owing to the social context and technological level. As I swim into the complex details of the main historical period of research ethics, it becomes evident that the evolution of research ethics is intertwined with the pursuit of social responsibility and justice. The main historical moment is: 1982, 1989, 1993, 1997, 2000, 2005, 2008, 2012, 2017, and 2020. During this period, significant developments were made in terms of research ethics. For example, there are the establishment of ethic committees, as the Declaration of Helsinki, and the integration of ethical considerations into research funding and publication practices These advancements have underscored the crucial importance of ethical awareness and accountability in the scientific domain, thereby stimulating ongoing discourse and self-reflection concerning research ethics. The proliferation of authors from various disciplines contributes to the complexity of the ethical challenges in science. Many authors prioritize journal relevance to research areas over impact factors when making publication decisions. The geographical map of research ethics publications shows that America leads research ethics publications, followed by Europe, Australia, Asia, and Africa. The current lack of understanding of ethical research practices, social responsibility, and the importance of cultural sensitivity in scientific research across various regions and cultural groups is a significant knowledge gap that needs to be addressed, particularly by South Saharan African researchers. Emerging topics such as data security, privacy, the ethical implications of AI, and digital connectivity animate scientific debate, even if there is insufficient knowledge production in agricultural science. However, this study is exploratory, mostly as a way to set an agenda for further research.
