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.

The same person fleeing the same crisis might face a fast, fair asylum process in one country and years of limbo in another, based purely on geography. A more consistent international standard remains unbuilt.

Anti-corruption agencies are sometimes created by the same officials they're meant to hold accountable, limiting how far they can actually investigate. Genuine independence for these watchdogs remains rare rather than standard.

When a country can't repay its debts, negotiations with lenders happen case by case with no consistent rules, often favoring lenders over the country's ability to recover. This can trap nations in cycles of debt renegotiation that stall development for years.

Public figures often face harsher scrutiny for behavior that would be judged more leniently in private citizens, and it remains unresolved whether this distinction is genuinely fair or simply a social double standard. This unresolved tension shapes debates over accountability and public trust.

Most people naturally apply different moral standards to close relationships versus strangers, but it's unclear whether this differential treatment is ethically justified or simply an ingrained bias. This unresolved question challenges the idea of a fully impartial ethical framework.
