Moral Dilemmas: 15 Real Examples and How the World Votes
The most famous moral dilemmas with concrete examples — from the trolley problem to AI ethics. See live SplitVote poll results for each one.
A moral dilemma isn't just a hard problem. It's a situation where both choices are defensible — and you have to pick one anyway.
Here are 15 concrete examples of moral dilemmas — from classic philosophy to everyday situations. For each one, you can see how the world votes on SplitVote.
What Makes a Real Moral Dilemma
It's not enough for the choice to be difficult. A moral dilemma has three features: both options have real, significant consequences; neither is clearly wrong on ethical grounds; the choice reveals a conflict between genuine values — not between good and evil.
Dilemmas don't exist to find the right answer. They exist to show which value wins when two values collide.

The Classics: Dilemmas That Have Lasted Decades
1. The Trolley Problem
A runaway trolley is heading toward five people tied to the track. You can divert it to a side track where one person is tied. Do you pull the lever?
The split is more balanced than most people expect before voting. See the live result on SplitVote.
2. The Organ Harvest
A surgeon can save five dying patients by taking organs from one healthy patient without consent. The math is identical to the trolley problem. The votes tell a different story.
The medical context shifts moral perception — even with identical numbers. See the live result on SplitVote.
3. The Lifeboat
A lifeboat holds 8 people. There are 12 survivors. Someone has to decide who boards — and who stays in the water. Who has the right to decide? On what basis?
Dilemmas About Truth and Loyalty
4. The Friend's Secret
Your best friend asks for your honest opinion on something important. You know the truth will hurt them. What do you do?
The split between those who say everything and those who protect their friend is sharp. See the live result on SplitVote.
5. Report or Stay Silent
You discover that a close friend has committed a serious crime. You witnessed it yourself. Do you report them or say nothing? The result shifts significantly depending on how the crime is described.
6. The Forbidden Cure
A cure exists for a fatal disease. But obtaining it requires an action most people consider ethically unacceptable. Would you do it?
Dilemmas About Identity and Memory
7. Erasing a Memory
You can delete the most painful memory of your life. The catch: that memory shaped who you are. After the erasure, you'd be a different person. Is it worth it?

8. Starting Over
Live another 40 years as you are now — or another 80 starting from scratch, with nothing you've built. Which do you choose?
9. Knowing Your Death
You're offered the chance to know the exact date of your death — but not the cause. Or the cause — but not the date. Pick one.
Everyday Life Dilemmas
10. The Betrayed Partner
You find out that your best friend's partner is cheating on them. Your friend hasn't asked you anything. Do you tell them?
11. Sacrificing for the Future
A costly action for you today could prevent enormous suffering for many people twenty years from now. No guarantees. Nobody will know. Do you act?
12. The Doctor Who Chooses Not to Tell Everything
A doctor knows that communicating the full diagnosis would psychologically destroy the patient and reduce their chances of survival. Do they tell everything — or choose what to reveal?
13. The Predictive Algorithm
An AI system predicts with high accuracy who will commit a serious crime in the next five years. Can you restrict those people's freedom before they've done anything?
14. The Difficult Inheritance
You can receive a large fortune from someone you considered morally reprehensible. The money would be yours, unconditionally. Do you accept it?
15. The Only Spot
Two people. One spot to be saved. One is your sister. The other is a doctor who could save many lives in the future. Who do you choose?
What the Votes Reveal
The most interesting thing in SplitVote results isn't which option wins. It's that almost every dilemma splits significantly — often 40/60 or 45/55 — even when the answer seems obvious before voting.
Moral dilemmas don't test your ethical knowledge. They test which value system you've internalized: consequentialist (outcomes matter), deontological (actions matter in themselves), or virtue-based (what would a person of integrity do?). Most people hold all three — until a dilemma puts them in direct conflict.
Try It Yourself
Reading a dilemma and actually voting are two different experiences. The moment you have to really choose, the position that seemed obvious becomes suddenly much less clear.
