How to Choose High-Impact Problems

Why Problem Choice Matters More Than You Think

Most people choose careers based on personal fit, salary, or prestige. But if you care about making a meaningful difference in the world, one of the most important decisions you’ll ever make is which problem to focus on. The same effort, talent, and dedication can lead to vastly different outcomes depending on whether you’re working on a small, well-solved issue or a large, neglected, and solvable global challenge.

Some problems affect billions of lives, while others affect only a few thousand. Some are already receiving massive attention and funding; others are overlooked despite their severity. Some have clear, actionable solutions; others remain stubbornly resistant to progress. Choosing the right problem to work on can multiply your impact by orders of magnitude.

Three Core Dimensions of a High-Impact Problem

To systematically compare different problems and decide where to focus, it helps to break them down into three key dimensions: scale, neglectedness, and tractability. These are not the only factors that matter, but they provide a powerful starting point for thinking about impact.

1. Scale: How Big Is the Problem?

Scale refers to how much harm or benefit is at stake. A high-scale problem is one that affects many people, animals, or future generations, or that has very severe consequences for those affected.

When assessing scale, ask:

• How many beings are affected?
• How severely are they affected?
• Over what time horizon does the problem matter?
• Could it affect the long-term trajectory of civilization?

For example, climate change is a high-scale problem because it affects nearly everyone on Earth, threatens food and water security, increases the risk of extreme weather, and could destabilize societies over the coming decades. Similarly, risks from advanced artificial intelligence or nuclear war are high-scale because they could determine whether humanity has a long-term future at all.

In contrast, a problem that affects only a small number of people, or that causes relatively minor harm, is lower in scale. That doesn’t mean it’s unimportant, but it does mean that, all else equal, it’s less likely to be the highest-impact area to focus on.

2. Neglectedness: How Much Attention and Resources Does It Get?

Neglectedness measures how much effort and funding are already being devoted to a problem relative to its scale. A highly neglected problem is one where additional resources can go a long way because there are few people or organizations working on it.

When evaluating neglectedness, consider:

• How many people are working on this problem?
• How much funding is being spent on it?
• Are there obvious bottlenecks (e.g., talent, funding, political will) that could be addressed?
• Is the problem under-researched or under-discussed in public discourse?

For instance, some global health issues in low-income countries are highly neglected relative to their scale. Millions suffer from diseases that are relatively cheap to treat or prevent, yet receive far less attention than diseases that are more visible in wealthier countries. Similarly, long-term risks like engineered pandemics or misaligned AI are still relatively neglected compared to their potential scale, meaning that additional work in these areas could have an outsized impact.

A problem that is already well-funded and crowded with experts may still be worth working on, but it’s harder for an additional person or dollar to make a big difference. In such cases, impact often depends on exceptional talent or finding a particularly high-leverage niche.

3. Tractability: How Solvable Is the Problem?

Tractability is about how much progress can realistically be made. A tractable problem is one where there are plausible ways to reduce the harm or improve the situation, and where additional effort is likely to lead to measurable results.

To assess tractability, ask:

• Are there proven interventions or strategies that work?
• Are there clear next steps or research questions?
• Are there major obstacles (e.g., political, technical, or social) that make progress very difficult?
• Is the problem so complex or poorly understood that it’s hard to know where to start?

Some problems are highly tractable because they have clear, cost-effective solutions. For example, distributing bed nets to prevent malaria or deworming children in areas with high parasite prevalence are interventions with strong evidence of effectiveness. Others, like reducing existential risks from advanced technologies, are less tractable because they involve deep uncertainty, complex systems, and long time horizons. That doesn’t mean they’re impossible to make progress on, but it does mean that impact is harder to predict and may require more foundational work.

Putting the Dimensions Together

When choosing a problem to focus on, the ideal case is a problem that is:

• Large in scale (affects many beings or has severe consequences)
• Highly neglected (few people or resources are working on it)
• Relatively tractable (there are plausible ways to make progress)

Problems that score highly on all three dimensions are often the most promising candidates for high-impact work. However, in practice, trade-offs are common. A problem might be huge in scale but very hard to solve, or very tractable but already well-funded.

Example: Comparing Two Global Health Problems

Imagine comparing two global health issues:

• Problem A: A disease that affects 100 million people, causes moderate suffering, and has a simple, cheap treatment. Many organizations already work on it, and funding is abundant.
• Problem B: A disease that affects 10 million people, causes severe disability, and has a treatment that is effective but underused due to lack of awareness and infrastructure. Very few organizations focus on it.

Problem A is larger in scale and more tractable, but less neglected. Problem B is smaller in scale and slightly less tractable, but much more neglected. In this case, additional resources on Problem B might have a higher marginal impact because they’re going into a gap where they can make a big difference.

How to Apply This Framework to Your Career

Once you understand the three dimensions, you can use them to guide your career decisions. Here’s how to apply the framework in practice.

Step 1: Brainstorm a List of Problems That Matter to You

Start by listing problems that you care about and that seem important. These could be global issues (e.g., climate change, global health, animal welfare, AI safety) or more specific challenges (e.g., improving education in a particular region, reducing plastic pollution, or advancing mental health care).

Don’t worry about being comprehensive or perfectly accurate at this stage. The goal is to generate a broad set of options to evaluate.

Step 2: Score Each Problem on Scale, Neglectedness, and Tractability

For each problem on your list, roughly estimate how it scores on the three dimensions. You can use a simple scale (e.g., low, medium, high) or a numerical score (e.g., 1–10).

For example:

This kind of table helps you see patterns and trade-offs. It’s not about getting the numbers exactly right, but about making your thinking more explicit and comparable.

Step 3: Consider Personal Fit and Leverage

The three dimensions are crucial, but they’re not the whole story. You also need to consider:

• Personal fit: How well do your skills, interests, and values align with the problem?
• Leverage: Are there high-leverage roles (e.g., research, policy, entrepreneurship) where you could have more impact than in a typical role?
• Long-term potential: Could work on this problem open up even higher-impact opportunities in the future?

For example, a problem might be highly important, but if you have no relevant skills or passion for it, you may struggle to sustain your efforts or excel. Conversely, a slightly less important problem where you have exceptional talent and motivation might still be a better fit.

Step 4: Narrow Down and Explore Further

Use your scores and personal fit considerations to narrow your list to a few top candidates. Then, dive deeper into each one:

• Read key reports and research on the problem.
• Talk to people who work in the area.
• Look for concrete ways to contribute (e.g., specific jobs, projects, or organizations).

This deeper exploration often reveals new information that changes your initial assessment. A problem that seemed intractable might have promising new approaches, or a neglected area might turn out to have hidden complexities.

Common Pitfalls to Avoid

Even with a good framework, it’s easy to go wrong. Here are some common mistakes and how to avoid them.

1. Overweighting Personal Passion

Passion is important for motivation and long-term commitment, but it shouldn’t be the only factor. It’s possible to be deeply passionate about a problem that is small in scale or already well-served. Balance passion with a clear-eyed assessment of impact.

2. Ignoring Neglectedness

Many people focus only on scale and tractability, but neglectedness is often the key to high marginal impact. A problem that is already crowded with talent and funding may offer less room for additional contributions, even if it’s important and solvable.

3. Underestimating Tractability

Some problems are so complex or politically fraught that progress is extremely slow, even with lots of resources. Be honest about how much difference additional work is likely to make. If a problem seems almost impossible to move the needle on, it may be better to focus on a more tractable area, even if it’s slightly smaller in scale.

4. Focusing Only on Direct Work

Many people assume that to make a difference, they need to work directly on a problem (e.g., as a doctor, teacher, or activist). But indirect paths—like earning to give, building career capital, or working in high-leverage roles in policy, research, or technology—can sometimes have even greater impact.

FAQs About Choosing High-Impact Problems

How do I know if a problem is truly neglected?

Look at funding levels, the number of people working in the area, and how much attention it gets in media and policy discussions. Compare this to the scale of the problem. If a problem affects millions but receives only a tiny fraction of the resources devoted to larger, more visible issues, it’s likely neglected.

What if I care about multiple important problems?

It’s common to care about several issues. In that case, use the framework to compare them and decide which one offers the highest potential for impact given your skills and circumstances. You can still support other causes through donations, advocacy, or side projects.

Is it better to focus on short-term or long-term problems?

Both matter. Short-term problems (e.g., global health, poverty) affect people now, while long-term problems (e.g., existential risks, institutional reform) can shape the future of humanity. Many high-impact careers involve a mix: building skills and resources in the short term to work on long-term priorities later.

Can I make a difference if I’m not an expert?

Absolutely. Many high-impact roles don’t require deep expertise at the start. What matters more is being willing to learn, being thoughtful about where to focus, and being persistent. Many people start in generalist roles and develop expertise over time.

How often should I re-evaluate my problem choice?

It’s wise to re-evaluate every few years, especially as you gain more experience and the world changes. New problems emerge, new evidence becomes available, and your skills and values may evolve. Regular reflection helps ensure you stay on a high-impact path.

Final Thoughts: A Tool, Not a Formula

The framework of scale, neglectedness, and tractability is a powerful tool for thinking about which problems are most worth solving. It helps you move beyond gut feelings and conventional wisdom to make more deliberate, evidence-based choices.

But it’s not a rigid formula. Real-world decisions involve uncertainty, trade-offs, and personal values. Use the framework to clarify your thinking, compare options, and avoid obvious pitfalls—but also stay flexible, open-minded, and willing to update your views as you learn more.

Ultimately, the goal isn’t just to pick a problem, but to build a career and life that make a meaningful difference. By choosing wisely, you can ensure that your time and talents are directed toward the challenges that matter most.
