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.

Automated scheduling, evaluation, pricing, and dismissal may shape work without a visible manager. The unresolved problem is giving workers collective voice over systems that are proprietary, dynamic, and difficult to audit. 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.

Algorithmically designed foods may optimize cost, taste, shelf life, or emissions while neglecting long-term health and cultural acceptability. The challenge is creating transparent nutritional and ethical evaluation. Decisions must account for people who will inherit long-lived infrastructure, environmental changes, and institutional commitments. 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.

Algorithmically designed foods may optimize cost, taste, shelf life, or emissions while neglecting long-term health and cultural acceptability. The challenge is creating transparent nutritional and ethical evaluation. The problem cannot be solved by one jurisdiction because people, ecosystems, data, supply chains, or risks cross national boundaries. 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 rental, mortgage, insurance, and zoning systems may reproduce historical exclusion through apparently neutral variables. Cities need transparent testing, appeals, and anti-discrimination safeguards. 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.

Shelving systems that conceal books until a reader meets algorithmic criteria restrict curiosity and self-directed learning. The challenge is supporting progressive discovery without gatekeeping physical or digital collections.

Digital calendars that prune events judged irrelevant to a user’s preferred life story erase inconvenient or painful but real experiences. The challenge is giving people control over their records without algorithmic narrative curation.

Windows that show personalized or algorithmically chosen realities fracture the common visual environment. The problem is preserving enough shared external reference for coordination, safety, and social cohesion while still allowing beneficial personalization.

When collective memory of shared events is rewritten in real time by majority vote or algorithmic consensus, no stable historical baseline remains. The problem is creating durable, independently verifiable archives that coexist with participatory updating without being overwritten.

Constant algorithmic renaming of streets undermines maps, emergency response, local knowledge, and historical continuity. The challenge is allowing dynamic naming for cultural or commercial reasons while preserving reliable addressing and navigation for residents and services.

Residences that rearrange themselves overnight according to algorithmic mood forecasts may increase comfort for some while creating disorientation, loss of control, or surveillance concerns for others. The challenge is balancing adaptive environments with resident agency, privacy, and predictability.

As machine learning enters welfare, policing, housing, tax, and licensing systems, bias can become harder to detect and contest. The open problem is creating enforceable standards for fairness, appeals, and independent review across all public-sector uses of automated decision-making. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

Content that provokes strong emotional reactions tends to get algorithmically boosted because it keeps people engaged longer, regardless of whether it's accurate or healthy. Redesigning these systems without destroying platform business models remains unresolved.

Despite recognition of its importance, reliable methods for participatory budgeting designs resistant to elite and algorithmic capture are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
