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.

Modern AI models produce answers without a clear, checkable chain of reasoning, making it hard to know if a correct answer was reached for the right reasons. Verifiable reasoning is essential before AI can be trusted in high-stakes decisions.

Existing tests focus on known-answer questions rather than open research tasks. Benchmarks that evaluate models on genuine research subtasks can guide development.

If a machine intelligence ever matched or exceeded human reasoning, questions about its moral status and rights would become urgent very quickly. Philosophy currently has no settled framework ready for that possibility.

Gödel's incompleteness theorems already showed some truths escape any fixed formal system, but the full boundary between provable and unprovable truths remains an active area of exploration. This shapes how we understand the limits of formal reasoning itself.

Certain simple-sounding tiling and packing puzzles remain surprisingly resistant to a complete general solution. These problems test the limits of combinatorics and geometric reasoning.

Formal proof systems capture enormous portions of mathematical reasoning, but whether a truly complete and finite rule set exists for absolutely every valid form of proof remains philosophically and technically unresolved. This touches the very foundations of what mathematics is capable of expressing.

Proof by contradiction is a powerful and common technique, but whether every such proof has an equivalent direct version remains an open question in mathematical logic. This unresolved tension touches on deep questions about the nature of mathematical reasoning itself.

Concern about how one will be remembered can shape real decisions in ways that may or may not align with genuinely ethical reasoning. This unresolved tension raises questions about the proper role of legacy in moral motivation.

If moral status depends on capacities like reasoning or suffering rather than being human specifically, then sufficiently advanced machines or aliens could theoretically deserve equal consideration. This unresolved question has growing relevance as artificial intelligence advances.

Some argue long-standing traditions encode valuable accumulated wisdom, while others see this reasoning as a way to justify practices that are simply unjust. Balancing respect for culture with universal ethical standards remains unresolved.

Some philosophers argue all observation and reasoning is inevitably shaped by underlying values, while others maintain a meaningful distinction between fact and value can still be preserved. This unresolved question underlies much of epistemology and philosophy of science.

Classical logic struggles with situations involving incomplete information or conflicting evidence, both common in the real world. A more flexible logical system could improve everything from AI reasoning to legal decision-making.

Modern AI models are often accurate but operate like black boxes, even to the people who built them. Without a way to explain their reasoning, it's hard to trust them in medicine, law, or other high-stakes decisions.
