85 Ethical Debate Topics and 12 Classic Ethical Dilemmas to Argue

What Makes an Ethical Debate Topic Good

An ethical debate topic is good when reasonable people, given the same facts, still disagree on what to do. That is the whole test. "Is murder wrong?" fails it: there is no real dilemma. "Should parents be allowed to screen embryos and select against predicted personality traits?" passes it, because moral principles people genuinely hold come into conflict.

This page has two parts. First, 12 classic ethical dilemmas to debate, the thought experiments philosophers and psychologists have argued over for decades, each with who formulated it and the strongest case for both sides. Then 85 ethical debate questions organized by domain: bioethics, technology and AI, business, criminal justice, personal morality, and political ethics. Each of those comes with a one-line framing of where the disagreement actually lives.

For other lists, see good debate topics, controversial debate topics, and AI ethics debate topics. For more abstract resolutions (metaethics, epistemology, philosophy of mind, political philosophy), see philosophy debate topics.

How to Use This List

Pick topics where you can state the strongest argument for the side you disagree with. If you can't, you don't understand the topic well enough to debate it yet. Spend prep time reading people who argue against your default position.

For Lincoln-Douglas rounds, choose topics that resolve into a clear value clash (autonomy vs. welfare, justice vs. mercy, individual rights vs. the collective good). For Public Forum or classroom discussion, choose topics with concrete policy stakes. For a philosophy club, the classic dilemmas below are the best starting point because they strip a problem down to one moral variable.

For the skill of arguing both sides, see how to win a debate, steelmanning, and how to think on your feet.

Ethical Dilemmas to Debate: 12 Classics

An ethical dilemma is a situation where two moral obligations conflict, so honoring one means breaking the other. The cases below were built to isolate a single question, such as whether killing is worse than letting die, or whether good ends can justify using a person as a means. That makes them ideal for debate: each side has a serious philosophical tradition behind it.

1. The Trolley Problem (Philippa Foot, 1967)

A runaway trolley will kill five people on the track ahead. You can divert it onto a side track, where it will kill one. Foot's original, in her 1967 paper on the doctrine of double effect, put the tram's driver at the controls; Judith Jarvis Thomson named it "the trolley problem" in 1976 and later recast it with a bystander at a switch.

• Case for switching: Five deaths are worse than one. You aren't using anyone; the one person's death is a side effect of redirecting a threat that already exists.
• Case against: Switching makes you the cause of a death that would not otherwise happen. Letting a tragedy unfold is morally different from killing to prevent it.

Motion: You are morally required to pull the lever.

2. The Footbridge Variant (Judith Jarvis Thomson)

Same trolley, same five people. This time the only way to stop it is to push a large man off a footbridge into its path. Thomson developed this variant to show that the numbers stay the same while most people's answer flips.

• Case for pushing: If the outcome is what matters, this is identical to the switch case. Treating it differently is squeamishness, not ethics.
• Case against: Here the man's body is the means of saving the others. Using a person as a tool violates his dignity in a way redirecting a trolley does not (Kant's principle of never treating people merely as means).

Motion: There is no moral difference between the switch case and the footbridge case.

3. The Transplant Surgeon (Thomson, 1976)

Five patients will die without organ transplants. A healthy visitor is a match for all of them. Should the surgeon kill one to save five? Thomson paired this with the trolley case because almost everyone says no, even though the arithmetic matches.

• Case for: A strict consequentialist has trouble explaining why five lives don't outweigh one here.
• Case against: A world where hospitals might harvest you would destroy trust in medicine, and individual rights exist precisely to block this kind of trade.

Motion: If it is right to switch the trolley, it is right for the surgeon to operate.

4. The Lifeboat (R v Dudley and Stephens, 1884)

After the yacht Mignonette sank in 1884, four survivors drifted for weeks. Two of them killed the 17-year-old cabin boy, Richard Parker, and the survivors ate him. The English court ruled that necessity is no defense to murder; the death sentences were commuted to six months in prison. Garrett Hardin later used "lifeboat ethics" (1974) as a metaphor for rich nations deciding whom to help.

• Case for the sailors: Without the killing, all four would likely have died. Law should not demand heroism that no ordinary person could meet.
• Case against: No one gets to decide whose life is worth less. Allowing necessity as a defense invites the strong to choose the weak as victims, which is what happened.

Motion: Necessity should be a defense to murder in extreme survival cases.

5. The Heinz Dilemma (Lawrence Kohlberg, 1958)

Heinz's wife is dying of cancer. A druggist has a drug that could save her; it cost him $200 to make and he charges $2,000. Heinz can raise only $1,000, and the druggist refuses to sell it cheaper or let him pay later. Should Heinz break in and steal it? Kohlberg used the story in interviews starting with his 1958 doctoral research at the University of Chicago to study stages of moral reasoning. What mattered to him was the reason people gave, not the yes or no.

• Case for stealing: A human life outweighs a property right, especially when the owner is exploiting desperation.
• Case against: If everyone who judged their cause important enough could break the law, property and law would collapse. Heinz has other options, like public appeals.

Motion: Heinz is morally justified in stealing the drug.

6. The Violinist (Judith Jarvis Thomson, 1971)

You wake up with an unconscious, famous violinist's circulatory system plugged into yours. He needs your kidneys for nine months to survive. Thomson used this case in "A Defense of Abortion" to argue that even if a fetus is a person, a right to life does not include a right to use someone else's body.

• Case for unplugging: No one can be forced to donate their body to keep another person alive, not even for a few months. We don't force parents to donate a kidney to their children.
• Case against: Critics argue the analogy fails because pregnancy usually follows a voluntary act and the fetus is the woman's own offspring, not a stranger she was kidnapped for.

Motion: A right to life does not include a right to use another person's body.

7. The Drowning Child (Peter Singer, 1972)

If you walk past a shallow pond and see a child drowning, you should wade in even if it ruins your clothes. Singer's essay "Famine, Affluence, and Morality" argues that distance makes no moral difference, so affluent people are obligated to give far more to prevent deaths overseas.

• Case for Singer: If you can prevent something very bad without sacrificing anything of comparable importance, you should. Physical distance doesn't change a child's worth.
• Case against: Obligations that demand almost everything you have make ordinary life impossible. Proximity, special relationships, and uncertainty about whether aid works are morally relevant.

Motion: Failing to donate to effective charities is morally equivalent to walking past the drowning child.

8. Jim and the Villagers (Bernard Williams, 1973)

A traveler named Jim stumbles on a captain about to execute 20 villagers. The captain offers a deal: if Jim shoots one, the other 19 go free. If he refuses, all 20 die. Williams used the case in Utilitarianism: For and Against to argue that utilitarianism ignores personal integrity.

• Case for shooting: 19 people live who would otherwise die, and the one victim was going to die anyway.
• Case against: Williams's point was that the answer isn't obvious. Jim becomes the instrument of the captain's evil, and a moral theory that treats his own agency as irrelevant is missing something.

Motion: Jim should shoot one villager.

9. The Ones Who Walk Away from Omelas (Ursula K. Le Guin, 1973)

A city of perfect happiness depends on one child kept in misery in a basement. Everyone knows. Most stay; a few walk away. Le Guin's short story won the Hugo Award in 1974.

• Case for staying: The suffering of one, however awful, is outweighed by the flourishing of thousands. Every real society already tolerates hidden suffering in exchange for comfort.
• Case against: Some things can't be bought at any price. Accepting happiness built on a child's torment makes you complicit.

Motion: Walking away from Omelas is the only moral choice.

10. The Experience Machine (Robert Nozick, 1974)

A machine can give you any experiences you want for the rest of your life, indistinguishable from reality. Would you plug in? Nozick posed the question in Anarchy, State, and Utopia to challenge the view that pleasure is all that matters.

• Case for plugging in: If what makes life good is how it feels, a machine that guarantees great experiences is a better life.
• Case against: We want to actually do things and actually be loved, not just feel as if we are. Reluctance to plug in suggests wellbeing involves contact with reality.

Motion: A life in the experience machine would be as good as a real one.

11. The Ring of Gyges (Plato, Republic, Book II)

In Plato's Republic, Glaucon tells of a shepherd who finds a ring that makes him invisible, then uses it to seize power. Glaucon's challenge: would anyone stay just if they could never be caught?

• Case that people wouldn't: Morality is a social bargain we keep out of fear of punishment and reputation. Remove the risk and self-interest wins.
• Case that they would, and should: Plato's answer through Socrates is that injustice corrupts the person who commits it. Character is its own reward.

Motion: A person who could never be caught would have no reason to be moral.

12. The Murderer at the Door (Immanuel Kant, 1797)

A would-be murderer asks where your friend is hiding. Kant, replying to Benjamin Constant in his 1797 essay "On a Supposed Right to Lie from Philanthropy," argued you still may not lie.

• Case for Kant: Truthfulness is a duty you owe to everyone, and once you permit lying for good reasons, trust in all statements erodes. You aren't responsible for the murderer's choices; you are responsible for yours.
• Case against: A rule that hands your friend to a killer is a reductio of the rule. Most moral traditions treat deceiving an aggressor as permissible, even required.

Motion: Lying is always wrong, even to prevent a murder.

Bioethics and Medical Ethics (1–18)

These are the topics where modern medicine has outrun the moral frameworks we inherited.

1. Should parents be allowed to use gene editing such as CRISPR to remove heritable diseases from embryos? No country explicitly permits heritable genome editing, and most that regulate it ban it. Parental autonomy and disease prevention vs. the consent of future persons and unknown long-term risks.

How to Build a Strong Case on an Ethical Topic

Ethical debates reward careful framework setup more than evidence dumps. Three moves carry most of the weight.

Establish your value framework first. Which moral standard should the round be judged by: consequences, rights, virtue, fairness? If your opponent doesn't contest the framework, you get to argue on your terms. If they do, the framework clash often decides the round.

Identify the principle, not just the case. A good ethical argument scales. "We shouldn't permit X" is weaker than "We shouldn't permit any action that meets conditions A, B, and C, and X meets them." The principled version survives counterexamples. This is where the classic dilemmas help: if your principle says switch the trolley, you need an answer for the transplant surgeon.

Address the strongest counter, not the weakest. Every ethical position has a serious objection. If you ignore it, the judge assumes you have no answer. Concede what's true in it and explain why your principle still wins.

Good sources for ethical rounds are philosophers, court opinions, and historical cases rather than statistics. The free Stanford Encyclopedia of Philosophy covers the doctrine of double effect, doing vs. allowing harm, and the moral theories these dilemmas test. For case construction, see how to write a debate speech and ethos, pathos, logos. For value-framework debate specifically, see Lincoln-Douglas debate.

Frequently Asked Questions

What is an ethical dilemma? An ethical dilemma is a situation where two moral obligations conflict, so doing one right thing means failing at another. Telling the truth vs. protecting a friend, or saving five vs. not killing one, are classic examples. Debating ethical dilemmas means arguing which obligation should win and why, not just stating which answer feels right.

What does "you enjoy debating ethical dilemmas" mean? It's a statement that appears in popular online personality questionnaires, including the 16Personalities test, where you rate how much you agree. It asks whether you like arguing through moral questions that have no clean answer, such as the trolley problem, rather than avoiding them. There is no right or wrong response; if you're curious whether you enjoy it, try arguing a few of the 12 dilemmas above.

What's the difference between an ethical debate topic and a political one? Political debates often turn on empirical questions about what a policy will do. Ethical debates turn on which principle should govern when people disagree about values. "Should we raise the minimum wage?" is mostly about economic effects. "Is it ethical to let wages fall below subsistence?" is mostly about which moral principle controls. Many real topics blend the two.

How do I pick ethical debate questions for a class? Pick topics where students can defend either side without feeling they've betrayed their identity. Topics that map cleanly onto political tribes tend to produce rehearsed talking points. The classic dilemmas, bioethics, and personal morality topics scramble those lines and produce real argument. For younger students, see middle school debate topics and high school debate topics.

Which debate formats suit ethical topics? Lincoln-Douglas is built around value resolutions, so most of the bioethics, criminal justice, and personal morality topics here convert directly into LD resolutions with a clear value clash. In Public Forum, rounds usually turn on concrete impacts, so translate the ethical principle into real-world effects. See debate formats explained for the differences.

How do I argue an ethical position I personally disagree with? Read the position's most thoughtful defenders, not its critics. Identify the moral intuition it is trying to honor, because every defensible ethical position protects some real human concern. Lead with that intuition. The same skill is useful in law, diplomacy, and journalism.
