Why is it in the News?

As India remoulds its scientific establishment, the utility of scientists being given administrative tasks needs to be questioned.

Context:

• Sustained economic progress which can satisfy national ambition is invariably fuelled by scientific advances translated into deployable technologies.
• This has been the inevitable global experience since the onset of the Industrial Revolution.
• The government is overhauling India’s science establishment, which includes setting up the new National Research Foundation (NRF) and restructuring the Defence Research and Development Organisation (DRDO).
• In this scenario, a frank assessment of the current administrative ability to simultaneously optimise Indian science’s efficiency and resilience is necessary.

What are the Problems with India’s Scientific Advancement?

India has a long and rich history of scientific innovation. However, in recent years, the country's science management has come under increasing scrutiny. There are several problems with India's science management including:

• Lack of Funding in Research and Development (R&D): One of the most pressing issues is a lack of funding.
  • India spends a relatively small percentage of its GDP on research and development, compared to other developed countries.
    • For instance, India allocates only about 0.7% of its GDP to R&D, a considerably lower figure compared to global leaders like the United States (3.5%) and China (2.4%).
  • This lack of funding has led to a brain drain of talented scientists, who are leaving India in search of better opportunities.
• Budgetary Challenges: The modest commitment to R&D stems from broader budget constraints, competing priorities, and a historical emphasis on immediate socio-economic needs.
  • This presents a challenge in fostering a robust scientific ecosystem on a limited budget.
• Lack of Coordination: Another problem with India's science management is a lack of coordination.
  • There are many different government agencies and departments that are involved in science and technology, but there is often a lack of communication and cooperation between them.
  • This can lead to duplication of effort and a waste of resources.
• Inadequacies in Budget Allocation by Scientific Administration: The current scientific administration struggles to identify and invest in high-impact projects.
  • For instance, in 2022, the Indian Space Research Organisation ranked eighth in space launches, lagging in key technologies.
  • Similar setbacks are evident in nuclear energy, genomics, robotics, and artificial intelligence.
• Lack of Strategic Planning and Execution: Beyond expenditure, the challenge extends to strategic planning and execution of scientific projects.
  • Failure to adapt swiftly to emerging technologies and allocate resources judiciously has resulted in India falling behind in crucial fields.
• Inconsistent Long-Term Funding: A major concern is the absence of consistent long-term funding for vital projects, especially when faced with occasional setbacks.
  • Steady funding, despite occasional failures, is crucial for a resilient and effective scientific management system.
• Finally, India's science management is often criticized for being too bureaucratic. The process of getting funding for research projects can be long and complex, and it can be difficult for scientists to get the support they need to succeed.

The Role of Senior Scientists in India’s Science Administration:

• Diverse Responsibilities Impacting Focus: Senior scientists in India often juggle multiple responsibilities, including academic pursuits, administrative duties, and leadership positions.
  • This dispersion of focus can lead to inefficiencies and a lack of dedicated attention to critical administrative tasks.
• Lack of Administrative Skills: The assumption that successful scientists can seamlessly transition into effective administrators overlooks the distinct skills required for scientific work versus administration.
  • Managing institutions, allocating resources, and making organizational decisions demand specific skills not necessarily possessed by accomplished scientists.
• Insufficient Training for Administrative Roles: Inadequate training makes it challenging for scientists to excel in administrative roles.
  • Tasks like metric selection, conflict resolution, and setting priorities require skills not inherently developed through scientific training.
  • Administration involves translating policy into outcomes, a skill not typically prioritized in scientific training.
• Conflicts of Interest and Quality Control Issues: The dual roles of scientists as academics and administrators can result in conflicts of interest within institutions.
  • Academic rivalries, bureaucratic challenges, and compromised quality control may emerge, leading to issues like plagiarism, unethical publication practices, and compromised scientific outcomes.
• Nationwide Transfer System Absence: The absence of a nationwide transfer system for scientists and science administrators exacerbates issues such as competition and egotism.
  • The lack of mobility within the system can contribute to internal divisions and hinder the progress of scientific careers and projects.
• Internal Control Challenges: Allowing individuals within the system to regulate it can lead to clear drawbacks, impacting the impartiality and effectiveness of science administration in India.

Challenges in India's Science Administration: A Historical Perspective

• Concentration of High-End Equipment: Economic constraints post-independence led India to concentrate on high-end scientific equipment, notably in institutions like the IITs.
  • This concentration birthed gatekeepers, controlling access to critical resources and establishing a hierarchical structure where a few institutions wielded disproportionate influence.
• Gatekeepers and Institutional Captures Concept: Over time, these gatekeepers solidified their positions, accumulating power, government support, and institutional control.
  • This system created an environment where young scientists navigated a complex web of influence, paying tributes to those controlling vital resources.
• Impact on Scientific Careers: The gatekeeping system not only influenced resource access but also shaped career trajectories.
  • The nexus between institutional power and individual careers became pivotal, with appointments, awards, and international recognition often tied to maintaining favourable relations with gatekeepers.
• Normalization of Unethical Practices: The gatekeeping system has normalized unethical practices within Indian science.
  • High plagiarism rates, paid publications in questionable journals, and undisclosed dealings for government funding have become ingrained, compromising the ethical standards of scientific research.
• Stifling Genuine Scientific Outcomes: This erosion of ethical standards doesn't just compromise research quality but stifles genuine scientific outcomes.
  • Scientists in conflict with this system face hurdles, hindering promising careers and perpetuating a culture where personal connections often outweigh merit.

A Comparative Analysis of the U.S. Model and Indian Science Administration:

• U.S. Model: In the U.S., scientists chosen for administrative roles are identified early in their careers and undergo targeted training for managerial tasks.
  • The emphasis is on maintaining a distinct separation between scientific pursuits and administrative responsibilities.
• Indian Scenario: In contrast, India's science administration traditionally involves senior scientists taking up administrative roles without a clear separation between scientific and administrative functions.
  • This integrated approach poses challenges, as the skill sets needed for effective scientific research often differ significantly from those crucial for efficient administration.

Conclusion

As India pursues economic and strategic progress, challenges in science management hinder its research and development, causing a lag in innovation compared to other developed nations. To remedy this, increasing funding for research and development is crucial, along with enhancing coordination among government agencies and streamlining the funding process for research projects. By addressing these issues, India has the potential to emerge as a global leader in science and technology, bringing substantial benefits to its economy and society.
