20 High-Impact Research Themes for Global Good

Many people feel drawn to research but are unsure how to choose topics that genuinely help others on a large scale. This guide introduces 20 influential research themes that can orient your work toward solving the world’s most pressing problems, while also helping you build a meaningful and sustainable career.

Why Focus Your Research on Global Impact?

Research can influence policy, technology, institutions, and philanthropy in ways that shape millions of lives. Public and philanthropic funding for science and policy is substantial, yet it is often not optimally allocated toward the biggest social challenges. Systematically choosing questions with large potential benefits, neglectedness, and tractability can therefore unlock disproportionate impact.

• Scale: Some global problems affect billions of people or future generations, so even incremental progress is valuable.
• Neglectedness: Many important questions receive little serious work compared with their importance.
• Leverage: Insightful research can redirect resources, reshape norms, and inform high-stakes decisions.

How to Read This Guide

The themes below condense popular and influential strands of work highlighted by the effective altruism and global priorities communities. They are grouped by broad area but overlap significantly. Use them to:

• Spot career directions that match your existing skills.
• Identify research questions for degrees, fellowships, or early-career projects.
• Understand how different disciplines can connect to real-world impact.

1. Global Priorities Research

Global priorities research asks which problems, interventions, and strategies matter most if we want to improve the world as much as possible with limited resources.

• Comparing the value of helping people now vs. in future generations.
• Modelling trade-offs between global health, poverty reduction, climate policy, and emerging technologies.
• Developing frameworks for resource allocation used by philanthropists and policymakers.

Researchers in economics, philosophy, decision theory, and statistics can all contribute, often working in interdisciplinary teams.

2. AI Safety and Alignment

Rapid progress in machine learning has raised concern about advanced AI systems that could behave in unintended and harmful ways. AI safety research seeks methods to align powerful systems with human values and maintain control as capabilities grow.

• Technical alignment: designing training objectives, architectures, and evaluation tools that reduce harmful behaviours.
• Robustness and interpretability: understanding why models behave as they do, and ensuring reliability under distribution shifts.
• Scalable oversight: finding ways for humans or AI-assisted systems to supervise increasingly capable models.

This area suits backgrounds in computer science, statistics, mathematics, and cognitive science.

3. AI Governance and Policy

Beyond technical safety, AI governance focuses on laws, institutions, and norms that shape how AI is developed and deployed globally.

• Designing regulations for testing and monitoring powerful models.
• Building international agreements to reduce race dynamics between states or firms.
• Ensuring that AI benefits are broadly shared and that power does not concentrate excessively.

This theme draws on law, political science, international relations, security studies, and public policy.

4. Biosecurity and Engineered Pandemics

Advances in synthetic biology and gene editing create tremendous benefits in medicine, but they also increase the risk of engineered pandemics and other biological threats.

• Improved detection systems for novel pathogens.
• Safe design and governance of dual-use biological research.
• Optimised vaccine platforms and rapid response infrastructure.

Biologists, clinicians, public health experts, and security scholars can all contribute substantially here.

5. Global Health and Development

Despite large gains over recent decades, hundreds of millions of people still live in extreme poverty, and preventable diseases cause millions of deaths yearly. Research in global health and development aims to identify interventions that offer the greatest improvements for people in low-income settings.

• Cost-effectiveness of health interventions such as vaccination, malaria control, or deworming.
• Cash transfers, education, and policy reforms to boost welfare and income.
• Prioritisation among competing global health and development programs.

Economists, epidemiologists, and social scientists frequently collaborate with governments and NGOs in this space.

6. Climate Risks and Long-Term Stability

Climate change threatens human health, food security, and ecosystems, and could interact with other risks such as conflict or migration. While climate change is studied intensively, some high-stakes questions remain underexplored:

• Extreme or tail-risk climate scenarios and their interaction with political stability.
• Governance of carbon removal and geoengineering technologies.
• Design of resilient energy and food systems under severe stress.

Research here benefits from earth sciences, economics, political science, and engineering.

7. Nuclear War and Great Power Conflict

Nuclear weapons and geopolitical tensions between major powers remain a significant global risk. Research can help reduce the likelihood and impact of large-scale conflict.

• Arms control and verification technologies.
• Crisis management and escalation modelling.
• Historical case studies of close nuclear calls and lessons for policy.

International relations, security studies, and history are particularly relevant disciplines.

8. Reducing Factory Farming and Animal Suffering

Billions of animals live in intensive farming systems that may involve severe welfare harms. Research can quantify these harms and identify practical paths to reduce them.

• Measuring animal welfare across farming systems.
• Evaluating the impact of welfare reforms, alternative proteins, and consumer campaigns.
• Analysing the political economy of agricultural policy and industry change.

This theme involves animal welfare science, behavioural science, economics, and policy research.

9. Wild Animal Welfare and Ecology

Wild animals outnumber farmed animals by many orders of magnitude, yet their welfare is poorly understood. Research questions include:

• Typical lifespans, causes of death, and likely welfare levels for different species.
• How human interventions (such as conservation or urban expansion) change welfare at scale.
• Ethical and practical considerations for potential interventions in ecosystems.

Ecologists, philosophers, and quantitative modellers can help build this nascent field.

10. Moral Philosophy and Ethical Uncertainty

Moral philosophy underpins many choices in global priorities research, from how we value future generations to how we handle uncertainty about different ethical views.

• Population ethics and the value of preventing extinction versus improving existing lives.
• Decision-making under deep moral uncertainty.
• Defining and measuring well-being across different beings and experiences.

This work tends to be theory-heavy but can directly shape philanthropic and policy decisions.

11. Forecasting and Decision-Making

When evidence is fragmentary or long-term, forecasting and decision science can improve how institutions choose among uncertain options.

• Quantitative forecasting techniques and aggregation methods.
• Institutional decision-making processes that reduce bias and improve calibration.
• Design of expert elicitation and scenario planning tools.

Statistics, psychology, and organisational science are key here.

12. Macroeconomic Growth and Innovation

Long-run economic growth has historically been a major driver of health, wealth, and technological advance. Research can clarify when boosting growth most helps the global poor and future generations.

• Determinants of long-run productivity growth.
• Distributional effects of growth across countries and social groups.
• Policies that foster responsible innovation without amplifying catastrophic risks.

13. Institutional Design and Governance Quality

Strong, well-governed institutions can address problems more effectively and respond flexibly to new challenges. Research themes include:

• Mechanisms that improve policy evaluation, learning, and accountability.
• Design of independent agencies for high-stakes domains like AI and biosecurity.
• Reforms to reduce corruption and capture, especially in low- and middle-income settings.

This work crosses public policy, political economy, and law.

14. Metascience and Improving Research Systems

Metascience studies how science itself is done and how to improve its reliability and productivity.

• Replication rates and incentives in different disciplines.
• Grantmaking strategies that encourage high-risk, high-reward work.
• Open science practices and infrastructure.

Insights here can multiply the impact of research across all other themes.

15. Information Security for High-Stakes Systems

As AI models, biological data, and critical infrastructure become more powerful and interconnected, information security failures can have disproportionate consequences.

• Protecting AI weights, pathogen sequences, or sensitive datasets from misuse.
• Designing secure research environments for dual-use technologies.
• Developing norms and technical standards for responsible data sharing.

16. Long-Term Future and Existential Risk Studies

Some scholars study the long-term trajectory of civilisation, including risks that could permanently curtail humanity’s potential.

• Mapping existential risks from advanced technologies and natural threats.
• Analysing interventions that increase resilience, such as diversified food systems or robust governance.
• Ethical analysis of how to weigh low-probability, high-impact events.

17. History of Technological Change and Catastrophe

Historical research can reveal patterns in how societies have adopted new technologies and handled crises.

• Case studies of transformative technologies and discontinuous progress.
• Past pandemics, wars, and near-misses that almost led to catastrophe.
• Institutional lessons from successful risk reduction efforts.

Historians and social scientists can use archival work to inform present-day decisions.

18. Culture, Communication, and Norm Change

Many interventions rely on changing social norms or disseminating complex ideas effectively, from climate behaviour to biosecurity practices.

• Which communication strategies reliably shift behaviour on large scales.
• How cultural differences influence receptivity to global-risk narratives.
• Reducing mis- and disinformation about high-stakes technologies.

Psychology, communication studies, and sociology are well placed to address these questions.

19. Specialist Regional Expertise

Key decisions about AI, climate policy, and security will be made in a few pivotal countries. Developing deep regional expertise can therefore be highly impactful.

• Understanding political systems, policy processes, and strategic cultures.
• Building networks across governments, academia, and industry.
• Analysing how global risks intersect with local priorities.

20. Career Strategy and Talent Allocation

Finally, research on career choice and talent pipelines helps match people to the areas where they can do the most good.

• Mapping bottlenecks in high-impact fields (e.g., policy talent vs. technical researchers).
• Evaluating different training paths and their opportunity costs.
• Identifying promising but underexplored niches within major problem areas.

Comparing Research Themes at a Glance

Choosing a Theme That Fits You

To narrow down among these options, consider three questions:

• Fit: Which themes align with your skills, background, and interests?
• Need: Where are there clear talent shortages or neglected problems?
• Tractability: In which areas do you see concrete projects you could start in the next 1–3 years?

You do not need to commit for life: many researchers test a theme for a few years, then pivot based on results and emerging opportunities.

Frequently Asked Questions (FAQs)

Q1: Do I need a PhD to work on these research themes?

A PhD is helpful for many academic and policy research roles, but not mandatory for all of them. Some areas, such as AI safety engineering, forecasting, or policy analysis in think tanks, are open to people with strong quantitative or writing skills and relevant experience. Consider whether your target roles actually require academic credentials or whether portfolio work, publications, or industry experience can substitute.

Q2: How can I test my fit for a research career?

You can run small experiments: write short research memos, collaborate on a paper, assist a professor, join a research internship, or contribute to open projects. Pay attention to whether you enjoy long, open-ended problems, careful reading, and iteration on drafts. External feedback from mentors and peers is often more informative than self-assessment alone.

Q3: Which theme is “best” if I just want to maximise impact?

There is no universally best theme; your comparative advantage matters. A moderately important problem where you have an excellent fit can be a better choice than a slightly more pressing problem where you would struggle. Start by identifying a small number of promising options, then investigate each more deeply before deciding.

Q4: How do I avoid getting overwhelmed by the scale of these problems?

Focus on concrete projects with clear next steps, such as a thesis question, a policy brief, or a model you can build within months. Seek communities or mentors who can provide guidance and share the load. Remember that impactful research is usually the result of cumulative, incremental contributions over time.

Q5: Where can I learn more about high-impact problem areas?

You can explore overviews of global problems such as AI risk, engineered pandemics, climate change, and global health from organisations that specialise in cause prioritisation and evidence-based policy. These overviews often link to more detailed reports and academic literature you can use to identify concrete research questions.
