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.

child support not being paid remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

No single model may cause harm when many models, sensors, contractors, and institutions interact. Legal systems need ways to assign responsibility across complex sociotechnical chains. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

States may increasingly use prediction to allocate policing, welfare, migration, health, and education resources. Future rights frameworks must address errors, feedback loops, opacity, and the danger of being treated as a probability rather than a person. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

AI agents may generate large volumes of apparently independent opinions, proposals, and consultation responses. Governance systems must preserve authentic participation and prevent automated manipulation of democratic processes. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Future challenges such as AI, climate engineering, cyber conflict, and biotechnology cross borders but may be governed by incompatible national rules. The open problem is creating minimum safety floors without requiring complete political agreement. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Automated financial, information, military, and infrastructure systems may act in milliseconds while democratic institutions deliberate over months. The challenge is designing pre-authorized constraints, real-time oversight, and meaningful accountability. The solution must work with limited capital, intermittent services, and local maintenance capacity.
