Context
- Scientific research advances knowledge, addresses societal challenges and strengthens national development.
- Indian scientists deserve recognition for their contributions, and international visibility is one form of appreciation.
- However, the growing presence of Indian researchers in the top 2% scientists’ database should not become the ultimate measure of scientific excellence.
- The real value of research lies in its originality, quality, innovation and societal impact. Treating rankings as definitive indicators risks overlooking meaningful scientific contributions.
Understanding the Top 2% Scientists’ Database
- Purpose and Methodology
- Developed by John Ioannidis and his collaborators, the database uses publication and citation records from Scopus to identify influential researchers across scientific disciplines.
- However, its creators caution against treating inclusion as conclusive evidence of research excellence.
- Limitations of the Database
- First, it relies on publication and citation records without independently verifying research originality.
- Second, inaccuracies in author profiles and disciplinary classification can affect rankings. Third, research published in regional languages remains inadequately represented.
- Its impact scores also depend partly on authorship positions in multi-author publications, although authorship conventions differ across disciplines.
- Moreover, citation counts cannot establish whether a research paper is appreciated, criticised or merely mentioned.
- An analysis by John Philip in 2023 found that 12 of 71 Physics Nobel laureates and two of 66 Chemistry Nobel laureates from 1998–2022 were missing from the database.
- This demonstrates that exclusion does not necessarily indicate a lack of scientific merit.
Implications for Research
- Distinguishing Scientific Research from Scientific Communication
- A 2026 study published in Scientometrics identified science journalists Clare Dyer and Jacqui Wise in the 2025 database.
- Although science journalism deserves recognition, its contribution differs from original scientific investigation.
- The same study identified an author associated with 217 retracted papers in the database.
- These examples raise concerns about the database's ability to distinguish research quality, scientific communication and research integrity.
- Pressure on Young Researchers
- Excessive emphasis on rankings could influence research priorities in India.
- Young scientists may prefer popular subjects that attract citations rather than pursue intellectually challenging questions aligned with their interests.
- Fundamental research requires patience, sustained investment and long-term commitment, as discoveries often take years to produce measurable results.
- Similarly, applied research requires prolonged experimentation and technological development.
- Prioritising immediate recognition could discourage innovative and unconventional research.
The Way Forward: Towards a Comprehensive Research Assessment Framework
- Balancing Fundamental and Applied Research
- India needs both fundamental research and applied scientific innovation.
- Fundamental research expands knowledge and lays the foundation for future discoveries, while applied research converts scientific understanding into practical solutions.
- Therefore, research assessment must recognise different objectives and timelines instead of rewarding publications and citations alone.
- Making database inclusion a primary target could undermine meaningful scientific progress.
- Learning from International Practices
- International research assessment initiatives are increasingly moving away from excessive dependence on quantitative indicators.
- For instance, the Swiss National Science Foundation asks applicants not to include citation counts, journal rankings or institutional rankings in their CVs.
- This approach encourages evaluators to assess the actual quality and significance of research.
- India should adopt a similar framework incorporating originality, scientific integrity, innovation, collaboration and societal relevance.
- Peer evaluation and qualitative assessment must complement quantitative indicators.
- Recognising Diverse Scientific Contributions
- India's scientific achievements demonstrate why excellence must be recognised beyond individual rankings.
- Chandrayaan-3: Its successful landing near the Moon's south polar region demonstrated collective scientific expertise, advanced engineering and technological capabilities.
- SHAKTI microprocessors: Developed at IIT Madras, they represent progress towards indigenous semiconductor technology.
- NexCAR19 cancer therapy: Developed through collaboration involving IIT Bombay, Tata Memorial Centre and ImmunoACT, it demonstrates India's capabilities in advanced cancer treatment.
- Indigenous 4G technology stack: It reflects domestic innovation and technological self-reliance.
- CERVAVAC vaccine: Developed by the Serum Institute, it represents an important contribution to affordable healthcare.
- These achievements highlight the importance of teamwork, interdisciplinary collaboration and indigenous innovation.
- Scientists, engineers, technicians and institutions deserve recognition irrespective of their inclusion in international databases.
Conclusion
- India needs a scientific recognition system that values genuine contributions rather than numerical rankings.
- International databases can provide useful information about research visibility but should remain supplementary assessment tools.
- A strong scientific ecosystem must recognise those who discover, innovate, develop technologies, communicate knowledge and enable scientific progress.
- Encouraging intellectual independence, long-term research and socially relevant innovation will strengthen India's scientific capabilities.
- Ultimately, the true measure of scientific excellence is the advancement of knowledge and its contribution to humanity, not inclusion in a global ranking.
