How to Compare Global Problems and Choose Where to Make the Biggest Impact

There are far more important problems in the world than any one person can work on. To have a large positive impact, it helps to step back and compare issues systematically instead of just following whatever feels most urgent or familiar. This article outlines a practical way to compare global problems and decide where your time, skills, and resources can do the most good.

Why Comparing Problems Matters

Most people care deeply about more than one cause: poverty, climate change, animal welfare, future technologies, and many others. But work, donations, and political attention are limited. Comparing problems allows you to:

• Avoid spreading yourself too thin across many minor projects.
• Spot neglected but promising areas where extra effort is unusually valuable.
• Check your intuitions against data and careful reasoning instead of relying only on emotion or familiarity.
• Prioritize your career path and donations using the same seriousness you’d use in a major financial decision.

Global priorities researchers increasingly emphasize that systematic comparison can reveal opportunities for enormous impact that casual reflection misses, especially when outcomes are measured in lives saved or major risks avoided.

The Core Framework: Scale, Solvability, Neglectedness

A widely used way to compare global problems is to look at three key dimensions that multiply together:

• Scale: How big is the problem?
• Solvability: How much difference can extra effort make?
• Neglectedness: How many resources are already focused on it?

Thinking in this way is inspired by economic ideas about marginal returns and diminishing benefits: the fewer resources an important problem already has, the higher the potential value of one extra hour or dollar devoted to it.

1. Scale: How Large Is the Problem?

Scale captures the size of the harm or benefit involved. To assess it, you can ask:

• How many people or sentient beings are affected now and in the foreseeable future?
• How severe is the harm for each affected individual (e.g., illness, early death, loss of income, reduced well-being)?
• How long do the effects last (years, generations, or potentially much longer)?

Public health and economics often measure harms using metrics like disability-adjusted life years (DALYs) or income changes, which allow rough comparison across diseases, interventions, or regions. For example, the World Health Organization estimates burden of disease across causes in DALYs, enabling comparison between, say, malaria and road injuries.

2. Solvability: How Much Progress Is Realistically Possible?

Solvability concerns how tractable the problem is. Relevant questions include:

• Are there known interventions that already work measurably well?
• Does extra funding, talent, or political will plausibly scale those interventions?
• Are there promising research directions that could unlock much better solutions?

In economics and public policy, solvability is closely related to cost-effectiveness: the benefit you get per dollar (or per hour) invested. Independent evaluators often estimate, for instance, how many lives could be saved per $1,000 spent on a given health program.

3. Neglectedness: How Crowded Is the Space?

Neglectedness measures how much attention and resources the problem is already receiving. The key idea is that problems with overwhelming resources may have already picked the low-hanging fruit; additional investment can bring smaller marginal gains.

To assess neglectedness, ask:

• How much public and private funding goes into this area each year?
• How many researchers, advocates, and organizations are focused on the issue?
• Is the issue politically popular, or does it receive sustained media coverage?

Global development research suggests that some high-burden diseases, for example, receive far less research and development funding than their impact would justify, making them relatively neglected opportunities for donors and researchers.

A Simple Table for Comparing Problems

The framework becomes more useful when you turn it into a structured comparison. The illustrative table below shows how you might compare three causes qualitatively. The entries are just examples to demonstrate the method, not quantitative claims.

After filling in such a table with your own best estimates and notes, you can reflect on where your additional contribution might have the greatest marginal effect.

Gathering Rough Numbers Without Getting Stuck

You can make meaningful comparisons even if you are not a specialist. The goal is not perfect precision; it is to avoid being wildly wrong in ways that flip your priorities. Some strategies:

• Use trusted summaries from major public health bodies, multilateral organizations, or academic reviews for headline numbers like deaths per year or economic losses.
• Look for existing cost-effectiveness estimates by reputable research groups that compare interventions using DALYs, life-years, or similar metrics.
• Note your uncertainty explicitly, for example by marking entries as “low confidence” or giving ranges (“between 1 million and 10 million people affected”).
• Update iteratively: start with a quick assessment, then refine only where better information could plausibly change your ranking.

Policy analysts and economists frequently work with ranges and sensitivity analyses rather than single point estimates for this reason: the comparison is often robust even when exact numbers are uncertain.

Making the Comparison Personal: Fit and Motivation

Even if a problem scores very highly on scale, solvability, and neglectedness, it may not be the best choice for you personally. Two additional factors matter:

• Personal fit: How well do your skills, temperament, and credentials match the work that is most needed?
• Motivation and values: Can you see yourself staying engaged with this area for many years?

Research on career satisfaction and performance indicates that people tend to excel when their work draws on their strengths, offers autonomy, and feels meaningful in light of their values. That suggests you will likely contribute more over the long run in a high-priority area that also aligns well with your capabilities and motivations.

Questions to Probe Personal Fit

• Which tasks in this area would I do day-to-day (e.g., research, management, advocacy, technical work)?
• Do these tasks align with what I have been good at in the past?
• What credentials or experience would I need to be effective, and how hard would they be to obtain?
• How energized do I feel when I read and talk about this problem compared with other major issues?

Common Pitfalls When Comparing Problems

When people first try to compare global problems, certain recurring errors show up. Being aware of them can make your reasoning more reliable.

• Focusing only on vivid stories: Media coverage tends to magnify shocking or dramatic events rather than the largest or most solvable problems.
• Ignoring opportunity cost: Working on one problem generally means not working on others. It is important to ask, “Compared to what?”
• Underestimating neglected issues: If few people talk about a problem, it is easy to assume it must be unimportant, even when data suggest otherwise.
• Overvaluing familiarity: Problems you have studied or encountered directly may feel more pressing even if their overall scale or solvability is lower.
• Equating importance with moral urgency alone: A problem can be morally urgent yet very hard to influence; another may be less dramatic but far more tractable.

A Step-by-Step Process You Can Use

The following practical sequence can help you move from vague intentions to a clearer set of priorities.

Step 1: List Candidate Problems

Begin with a broad list of global issues you might plausibly work on or support, such as:

• Global health and poverty
• Climate change and environmental protection
• Risks from emerging technologies
• Animal welfare and food systems
• Democratic stability and institutional quality

Feel free to include both widely discussed problems and niche topics you have encountered through study or work.

Step 2: Do a First-Pass Assessment

For each problem on your list, write a few sentences or bullet points on:

• How many people seem affected and how severely (scale).
• Some promising ways extra resources might help (solvability).
• Roughly how much attention and funding it already gets (neglectedness).

Rank the problems into rough tiers (for example: top, middle, bottom) based on this initial pass. At this stage, speed matters more than precision; you are just looking for a small number of areas worth deeper investigation.

Step 3: Deepen Your Research on the Top Few

Pick the two or three most promising problems and spend several hours on each. For every problem, try to find:

• Recent reports from reputable institutions such as the World Health Organization, World Bank, or major academic centers.
• Any existing cost-effectiveness analyses or systematic reviews describing interventions in that area.
• Estimates of current funding levels, number of organizations, or policy initiatives.

Summarize your findings in a short note for each problem, including what you learned and where you still feel uncertain.

Step 4: Reflect on Your Personal Contribution

Once you understand the problems better, revisit them from the perspective of personal fit:

• What concrete roles exist in this area (e.g., technical specialist, policy analyst, operations manager, communicator)?
• Which roles match your current or potential skills?
• How might your contributions compare with what others can do?

It can help to talk with people already working in the field or to look at job listings and biographies to get a realistic picture of what impactful work looks like in practice.

Step 5: Choose a Direction, Then Keep Updating

After this process, aim to choose a working priority rather than a final answer. Commit to focusing your next major career move or donation plan on one or two top-ranked problems, then revisit your priorities every year or when you gain new information.

In public policy and strategic planning, it is normal to treat decisions as provisional and to build in review points, recognizing that new evidence or changing conditions can shift what is most impactful.

Balancing Quantitative and Qualitative Judgments

Numbers alone cannot capture everything that matters. For instance, some problems may have profound ethical significance that is hard to reduce to statistics, especially where future generations or non-human animals are involved. At the same time, purely intuitive comparison can be deeply misleading.

A balanced approach might involve:

• Using quantitative estimates (like DALYs averted or lives saved per dollar) as a starting point.
• Adding qualitative considerations, such as moral uncertainty, political feasibility, or resilience of progress to future shocks.
• Being explicit about where you are following evidence and where you are following deeper value judgments.

This style of reasoning mirrors how many high-stakes policy decisions are made: data inform the decision, but values ultimately guide which trade-offs are acceptable.

Frequently Asked Questions

Q: Is it really possible for an individual to compare global problems meaningfully?

Yes. While you may not become an expert in every area, you can still make better decisions by drawing on high-quality summaries, basic quantitative estimates, and a clear framework. The aim is not perfection but to avoid very large mistakes, such as focusing on a small, crowded issue when a much larger, more neglected one fits you just as well.

Q: Doesn’t focusing on neglected problems ignore urgent popular causes?

Focusing on neglectedness does not imply that popular causes are unimportant. It simply recognizes that when many people are already working on something, the marginal value of one extra person is usually lower. You may still decide to work on a well-known problem if your personal fit is exceptional or if you see a unique angle others are missing.

Q: How should I weigh current lives against future generations?

Reasonable people disagree about how much to prioritize the long-term future. Some moral frameworks give substantial weight to future people, especially when dealing with risks that could permanently curtail humanity’s potential. Others prioritize the urgent alleviation of present suffering. You can acknowledge this moral uncertainty, explore both perspectives, and, if appropriate, split your efforts between near-term and long-term causes.

Q: What if I am very uncertain between two or three top problems?

If your analysis leaves you genuinely torn, you could explore more than one area sequentially (for example, through internships, short-term roles, or side projects) and then commit more deeply once you have firsthand experience. In philanthropy, splitting your giving between a small number of top-rated issues can also be reasonable while you continue learning.

Q: How often should I revisit my priorities?

A practical approach is to review your cause priorities roughly once a year or when major new developments occur, such as breakthroughs, crises, or significant shifts in funding. This cadence is frequent enough to stay responsive to new information without causing constant upheaval.
