Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Research shows a strong link between childhood trauma and adult physical illness, but effective, scalable prevention and early intervention remain limited. Closing this gap could improve both mental and physical health outcomes across entire populations.

Stomach cancer often causes no clear symptoms until it has progressed significantly, particularly in regions without routine screening programs. Earlier, more accessible detection could substantially improve survival outcomes.

The same virus or bacteria can cause mild illness in most people while triggering severe, sometimes life-threatening complications in others, and we still don't fully understand why. This gap makes predicting and preventing severe outcomes difficult.

Some argue outcomes matter most regardless of how they were achieved, while others believe the means used fundamentally taint the value of the result. This unresolved tension appears throughout debates in both personal ethics and public policy.

Some long-term ethical frameworks argue humanity's continued existence matters more than any individual's current suffering, while others reject sacrificing real people for abstract future outcomes. This unresolved tension is increasingly relevant to debates on existential risk.

The absence of robust, context-adapted solutions for interventions that reliably improve mental health outcomes at population scale creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Achieving mechanisms for aligning the incentives of financial institutions with climate and sustainability outcomes at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.
