We haven't solved whether every even number greater than two is the sum of two primes.
open
Global / Unspecified, Global
Known as Goldbach's Conjecture, this simple-sounding statement has been checked for enormous numbers without exception, but never formally proven true for all numbers. It remains one of the oldest unsolved problems in mathematics.

We don't have a complete theory predicting how prime numbers are distributed.
open
Global / Unspecified, Global
Prime numbers appear to follow patterns at large scales but seem random up close, and mathematicians still lack a full explanation for this behavior. Understanding it better could improve encryption methods that rely on primes.

We haven't proven the Riemann Hypothesis, a problem central to understanding prime numbers.
open
Global / Unspecified, Global
This century-old conjecture predicts a hidden pattern in how prime numbers are distributed, but nobody has ever proven it true. A proof would deepen our understanding of numbers in ways that ripple into cryptography and physics.

We still don't know whether every math problem that's easy to check is also easy to solve.
open
Global / Unspecified, Global
Known as the P versus NP problem, this asks whether problems whose solutions are easy to verify are also easy to find in the first place. Answering it would reshape computer science, cryptography, and optimization overnight.

We haven't settled who should decide what values a global AI system should hold.
open
Global / Unspecified, Global
As AI systems increasingly influence what billions of people see, believe, and decide, someone is effectively choosing the values baked into those systems. There's no agreed process for who that someone should be, or how they should be held accountable.

We don't agree on how much punishment is justice versus revenge.
open
Global / Unspecified, Global
Justice systems around the world vary wildly in how harshly they punish the same crimes, reflecting different beliefs about what punishment is actually for. Whether punishment should aim to rehabilitate, deter, or simply punish remains unresolved.
Citation ID: WS00130
Title: We don't agree on how much punishment is justice versus revenge.

We haven't found a universal answer to what a meaningful life requires.
open
Global / Unspecified, Global
Different cultures, religions, and individuals define meaning and purpose in very different ways, with no way to prove one view more correct than another. This makes questions about how to live well deeply personal rather than settled.
Citation ID: WS00129
Title: We haven't found a universal answer to what a meaningful life requires.

We don't agree on the limits of free speech when speech can cause real, measurable harm.
open
Global / Unspecified, Global
Free expression is valued almost everywhere, but so is protection from harassment, incitement, and harmful misinformation, and these values often conflict directly. No universal line exists for where one right ends and the other begins.

We haven't settled how societies should treat people who cannot work due to automation.
open
Global / Unspecified, Global
As machines take over more jobs, some people may be unable to find meaningful paid work through no fault of their own. Whether society owes them support, and how much, remains a contested ethical and political question.

We don't have an agreed ethical stance on creating artificial minds capable of suffering.
open
Global / Unspecified, Global
If AI systems ever become capable of something like suffering, we would have created that suffering deliberately, and we don't have a moral framework ready for that possibility. This question is likely to become urgent faster than expected.

We haven't found a shared standard for what counts as a fair distribution of global resources.
open
Global / Unspecified, Global
Some countries and individuals consume vastly more resources than others, and there's no broadly accepted definition of what a fair share would even look like. This makes global cooperation on resource use difficult to justify to everyone involved.

We don't agree on how much say future generations should have in decisions made today.
open
Global / Unspecified, Global
Choices made now about climate, debt, and resource use will affect people who don't yet exist and have no voice in the decision. Philosophy hasn't settled how much weight their unheard interests should carry.

We haven't settled whether it's right to extend human life indefinitely if we could.
open
Global / Unspecified, Global
Advances in medicine keep pushing life expectancy higher, but there's no consensus on whether radically extending life is actually good for individuals or society. This question becomes more urgent as anti-aging research advances.

We don't have a widely accepted framework for who deserves blame when AI causes harm.
open
Global / Unspecified, Global
When an autonomous system makes a harmful choice, moral responsibility is hard to pin on any single party, the programmer, the company, or the AI itself. Ethics hasn't caught up with the reality of decisions made without direct human involvement.
Citation ID: WS00122
Title: We don't have a widely accepted framework for who deserves blame when AI causes harm.

We haven't found a shared answer to how much personal freedom should be limited for public good.
open
Global / Unspecified, Global
Vaccine mandates, speed limits, and lockdown policies all raise the same underlying question of how much individual liberty should bend for collective benefit. Different people and cultures answer this very differently, with no clear resolution.

We don't agree on how to weigh animal suffering against human convenience.
open
Global / Unspecified, Global
Factory farming, animal testing, and habitat destruction all cause animal suffering for human benefit, but there's no consistent ethical standard for how much suffering is acceptable and why. This gap shows up in inconsistent laws and practices worldwide.

We haven't settled what obligations wealthy nations owe to those harmed by their historical actions.
open
Global / Unspecified, Global
Colonization, slavery, and resource extraction left lasting harm in many parts of the world, and debates over reparations or restitution remain unresolved almost everywhere they're raised. There's no broadly accepted framework for addressing this.

We don't have a clear ethical line for editing the genes of unborn children.
open
Global / Unspecified, Global
Gene editing could prevent serious diseases, but it also opens the door to selecting traits that have nothing to do with health. Society hasn't agreed on where prevention ends and something more troubling begins.

We haven't agreed on how much responsibility individuals bear for problems caused by entire systems.
open
Global / Unspecified, Global
Climate change, inequality, and other large problems result from systems, not just individual choices, yet blame and responsibility are still often placed on individuals. How we think about this shapes both policy and personal guilt.

We don't have a shared answer for how much privacy people should give up for safety.
open
Global / Unspecified, Global
Surveillance can prevent crime and terrorism, but it also erodes personal freedom, and there's no consensus on where the right balance lies. Different societies draw this line in very different places.
