What Does 80,000 Hours Consider the World's Most Pressing Problems?

Updated

80,000 Hours is a career advice organization whose stated mission is to help people find work that makes a difference, with a current emphasis on making AI go well. It argues that the problem you choose to work on is probably the single largest factor in how much difference you can make, and it ranks global problems using three criteria: scale (how many people or how much value is affected), tractability (how solvable the problem is with additional effort), and neglectedness (how few other people are already working on it). Problems that threaten humanity's long-term future are treated as especially high priority. The organization explicitly labels its ranking as uncertain.

The screening criteria, explained

Before looking at the list, it helps to understand why these three criteria matter together:

  • Large in scale — the problem affects a great deal of value, potentially on a civilizational level.
  • Tractable — additional people and resources can plausibly make progress on it.
  • Unduly neglected — the problem receives less attention than its scale would justify, so an extra person can have more marginal impact.

A problem that is huge but hopeless, or huge but already crowded with talent, scores lower than one that is huge, solvable, and understaffed. This is why 80,000 Hours frames its list as a ranking of where additional people can have the most impact, not simply a list of the worst things in the world.

The most pressing problems on its list

Based on the organization's own ranking, the priority problems are:

Problem Why it ranks highly
Loss of control over AI We may develop very powerful AI systems before building adequate control mechanisms. If such systems accumulate power while misaligned with human values, the result could be catastrophic.
Extreme power concentration AI could turbocharge efforts to seize and hold power. Surveillance, persuasion, and control technologies could let small groups or authoritarian leaders entrench their rule, potentially with little chance of recovery.
Engineered pandemics Deliberately engineered biological threats could cause harm at a scale natural outbreaks rarely reach.
Great power conflict Conflict between major powers risks escalation and wide-reaching consequences.
Factory farming Affects an enormous number of animals and is argued to be comparatively neglected relative to its scale.

The organization presents this as its "(uncertain!) ranking," and the ordering above reflects the sequence it gives, with loss of control over AI at the top.

Why AI dominates the current framing

80,000 Hours states that many experts believe there is a roughly 1-in-10 chance (or worse) that AI could cause human extinction, and that this is why its mission is to help people find jobs focused on making AI go well. It notes that far more people — with both technical and non-technical backgrounds — are urgently needed.

This explains the structure of the list: several of the top entries (loss of control, extreme power concentration) are AI-related risks, while engineered pandemics and great power conflict are treated as related civilizational threats. Factory farming appears as a separate, non-existential priority.

What this means if you're choosing a career focus

  • Treat the ranking as a starting point for your own reasoning, not a verdict — the organization itself flags uncertainty.
  • The criteria (scale, tractability, neglectedness) are reusable: you can apply them to a problem the list doesn't cover.
  • The list is explicitly about where an additional person can add the most impact, so a crowded field can rank lower even if the problem is severe.
  • The organization says its research, podcast, and advisors exist to help people understand AI and key risks, figure out where they fit, and either skill up or find a role right away.

If your goal is to compare your own options against this framework, the practical move is to score each candidate problem on the three criteria and check whether the field is already well-staffed — then weigh that against your personal fit, since the ranking is a claim about impact, not about what any individual should do.
