How to Choose the Most Important Problem to Work On

You only have a limited number of working hours in your life, yet the world faces more important challenges than any single person could tackle. Choosing which global problem to focus on is therefore one of the most consequential decisions you will ever make.

This article offers a structured way to think about that choice, inspired by research on effective altruism and longtermist priorities, while remaining accessible for people at any stage of their career.

Why Your Choice of Problem Matters So Much

People often put enormous effort into getting a degree, finding a job and advancing in their field, but invest far less time in deciding whether they are advancing the right cause. Yet empirical work in global health and development shows that some interventions are hundreds of times more effective than others at improving lives per dollar or hour spent.

If the effectiveness of interventions varies this widely, then the area you work in can easily dominate your overall impact. Two similarly talented people, working equally hard, can have radically different effects on the world depending on which problems they choose to address.

• Your problem choice influences what skills you need to build.
• It shapes the networks, funding opportunities and mentors you encounter.
• It determines which future opportunities will even be visible to you.

A rough, informed choice is usually far better than simply following your first intuition or whatever opportunities appear in front of you.

The Four Central Factors for Comparing Problems

Researchers working on prioritizing global problems often suggest focusing on four core factors when comparing options.

Think of these four factors as different lenses on the same decision. Ideally you want a problem that scores reasonably well on all of them, but the best choice will depend on trade-offs and your individual circumstances.

Understanding Scale: How Big Is the Problem?

Scale is about the overall importance of a problem. It captures how many lives are affected, how badly, and for how long, including potential effects on future generations.

Questions to gauge scale

• How many people (or animals, or future beings) are affected each year?
• How severe is the harm per individual compared with other problems?
• Could the problem shape the long-term trajectory of civilization? (For example, existential risks such as catastrophic pandemics or unaligned advanced AI.)
• How does the best available data compare this problem with others in terms of lives saved, health improved, or economic outcomes per unit of effort?

Evidence-based organizations in global health and development have shown, for example, that some health interventions avert a year of severe illness or death at a small fraction of the cost of others, revealing vast differences in effective scale per dollar spent.

Assessing Neglectedness: Who Is Already Working on It?

Neglectedness measures how crowded an area is. A problem can be huge, but if governments, companies and charities already invest enormous resources into it, an additional person may have relatively little marginal impact.

How to think about neglectedness

• Estimate the rough level of funding, research attention and political focus already directed at the problem.
• Look for areas that are important, but overlooked because they are:
  • unpopular or emotionally distant (e.g., animal welfare in factory farming),
  • future-focused (e.g., safeguarding advanced technologies), or
  • hard to frame in a partisan way (e.g., biosecurity infrastructure).
• Ask whether key decision-makers even recognize the problem as a priority.

Neglectedness is not about ignoring popular issues entirely; it is about asking where additional resources are most needed at the margin.

Estimating Solvability: Can Additional Effort Make a Dent?

Solvability (sometimes called tractability) is about the proportion of the remaining problem that additional resources could realistically solve.

Practical signals of solvability

• There are tested interventions that have already made measurable progress.
• Experts can describe concrete, feasible next steps rather than only long-term aspirations.
• Small pilot projects have demonstrated strong results that could be scaled up with funding or talent.
• Legal, cultural or technological barriers seem surmountable rather than nearly fixed.

Some areas, such as distributing proven medical technologies, score relatively high on solvability, because robust evidence shows that additional funding and implementation capacity directly translate into better outcomes. Others—like resolving deep geopolitical tensions—may be far harder for any individual to influence in the short term.

Personal Fit: Matching Problems to Who You Are

Even if two problems are similar on the first three factors, they may differ dramatically in how well they match your skills, interests and temperament.

Components of personal fit

• Existing strengths – technical knowledge, communication skills, quantitative ability, management experience.
• Learnable potential – your track record of acquiring new skills and adapting to unfamiliar fields.
• Motivation – whether the problem energizes you enough to sustain effort over years.
• Access – networks, location, citizenship, and credentials that might open or close doors in a given area.

Personal fit is uncertain early in your career, and you will often learn the most about it by trying several paths through internships, side projects or short-term roles rather than purely theorizing.

A Step-by-Step Process for Choosing a Problem

Rather than aiming for a perfect answer, treat choosing a problem as an iterative process where you continually refine your view as you gather more information.

Step 1: List your candidate problems

Start with a broad set of options. For example:

• Reducing global poverty and preventable disease
• Mitigating catastrophic climate change
• Improving animal welfare, especially in intensive agriculture
• Reducing existential risks from emerging technologies (e.g., AI, bioengineering)
• Strengthening global governance and institutional decision-making

Step 2: Do shallow research on each

Spend a few hours for each problem gathering basic facts:

• Look for high-quality overviews (reports from global health bodies, climate assessments, or peer-reviewed reviews).
• Note how experts describe the problem’s current scale and trends.
• Write down examples of specific interventions, policies or research directions.

Step 3: Score your options on the four factors

You can use a simple scoring system, such as 1–5 for each factor:

• 1 = very low
• 3 = medium
• 5 = very high

For each problem, assign rough scores for scale, neglectedness, solvability and personal fit. Do this quickly at first; the goal is to produce a ranking that you can later challenge and improve.

Step 4: Speak with people working in the area

Brief conversations with practitioners often reveal details that are hard to find in reports:

• Which skills are most needed in the next 5–10 years?
• What are the main bottlenecks they experience day to day?
• Where have newcomers had the biggest positive impact recently?

These conversations also help you test your personal fit: you might find that the kind of work actually being done is more or less appealing than you expected.

Step 5: Narrow down and experiment

After updating your scores and reflections, choose one or two top candidate problems and commit to exploring them more deeply through:

• Internships or fellowships
• Targeted master’s or PhD work (if you enjoy research-intensive paths)
• Short projects, such as policy memos, technical prototypes, or local advocacy campaigns

You are not locking in a lifetime commitment at this stage. The aim is to gather high-quality feedback about both external impact and internal fit.

Examples of High-Priority Problem Areas

While you should ultimately form your own view, a number of research groups have flagged several clusters of problems as especially promising for people who want to maximize global impact.

• Global health and extreme poverty – Preventing deaths from infectious diseases, improving maternal and child health, and supporting evidence-based development policy remain powerful ways to help many people at relatively low cost.
• Catastrophic and existential risks – Issues such as unaligned advanced AI, engineered pandemics, and large-scale nuclear conflict could permanently curtail humanity’s future potential. Work in these areas may have vast long-term benefits.
• Climate change and environmental stability – Limiting warming and protecting ecosystems can reduce suffering, protect livelihoods, and lower the risk of cascading crises.
• Animal welfare – Billions of animals live in conditions of severe suffering in modern supply chains each year, yet the issue often receives relatively little political or philanthropic attention.
• Improving institutions and decision-making – Better policy processes, forecasting, and governance can indirectly improve outcomes across many other problem areas.

These areas differ widely in the skills they demand: from epidemiology, machine learning and biosecurity engineering to law, economics, communication and operations management.

Common Pitfalls When Choosing a Problem

As you reflect on where to focus, watch out for a few predictable mistakes.

• Confusing familiarity with importance – The problems you learned about in school or see daily in the news are not necessarily those where you can do the most good.
• Overweighting short-term emotional reactions – A striking story may grab attention, but large-scale data is often more informative for long-run decisions.
• Ignoring your personal constraints – Visa restrictions, health limitations, family commitments or financial obligations can influence which paths are realistic at a given time.
• Seeking certainty before acting – You will never have perfect information; instead, aim for robustly good options and remain willing to update.

Using Simple Heuristics When Time Is Limited

If you are under immediate time pressure—for example, needing to accept or reject a job offer soon—you can use short heuristics instead of a full analysis.

Quick impact check

For each opportunity you are considering, ask:

• Does this role plausibly contribute to a problem that is large, relatively neglected and somewhat solvable?
• Will this path build transferable skills or connections that are valuable for multiple high-impact areas?
• Could I switch course in a few years if I learn that another problem is more pressing for me to work on?

If the answer to these is broadly yes, the option is likely reasonable even if it is not your theoretical optimum.

Frequently Asked Questions

Q: Is it more important to find the right problem or the right role?

Both matter, but the problem you choose can change your long-run impact more than fine distinctions between similar roles. However, if a role is a terrible fit for your abilities and motivation, you may burn out or underperform even in a high-priority area. Aim for a combination: a promising problem area and a role that lets you genuinely excel.

Q: How soon in my career should I specialize in a specific problem?

Early on, it is usually better to build broad, transferable skills and experiment with several promising areas. Specializing deeply makes more sense once you have tested your personal fit and developed a clearer view of where your strengths are most valued.

Q: What if my ideal problem area is very competitive?

High-priority fields often attract many applicants for the most visible roles, but there are usually valuable supporting positions in operations, policy, communications and engineering that receive fewer strong candidates. Consider adjacent roles that use your strengths while keeping you close to the problem.

Q: How do I compare helping people today versus protecting future generations?

This is partly an ethical question and partly empirical. Some researchers argue that safeguarding humanity’s long-term future—by reducing existential risks—could be extraordinarily important if many future generations could exist. Others place more weight on helping those currently alive. You can explore both types of work early on and decide how much weight to give each perspective.

Q: Can I change my focus later without wasting my early career?

Yes. Skills like clear writing, project management, quantitative reasoning, software engineering, and policy analysis are valuable in many high-impact areas. If you deliberately build versatile abilities and networks, switching problem focus later can increase your contribution rather than nullify past efforts.
