What an ethics station is really marking
Almost every ethics scenario at a UK medicine or dentistry interview is built so that a thoughtful candidate could land on more than one defensible position. A scenario with a single obvious answer separates nobody.
The mark sheet rewards the route rather than the destination: the facts you gathered, the competing duties you noticed, the options you found beyond the two you were handed, and whether you took a position you could defend. Two candidates can reach opposite conclusions and score the same.
The scenario is the vehicle, not the cargo
You are not being asked to solve the case. You are being asked to show how you think when the answer is contested — which is what an examiner is relying on when you are a foundation doctor at two in the morning with nobody senior on the ward.
This article is a container rather than content. What you pour into it comes from the four pillars, from consent and capacity, and from confidentiality and when it breaks. If that material is thin, no structure will rescue you. If it is solid, structure makes it audible in the time you have.
The four moves
Learn this as a sequence you can run without thinking, so your attention goes on the case rather than on what to say next.
- Clarify and gather — say what you would need to know, and why each fact would change your answer.
- Name the tension — state the competing principles and the people affected, explicitly and out loud.
- Explore the options — always more than two, including the one the question hides.
- Take a position — commit, hold it with humility, and say what would change your mind.
Move one — clarify and gather
Almost no realistic dilemma can be settled from the prompt alone, and noticing that is often the first mark on the sheet. Say what you would want to know and why it matters, then reason down both branches if nobody will tell you. This buys thinking time while you are already talking, and shows that clinical decisions rest on facts rather than instinct.
- The clinical facts: how urgent, what the real risk is, what has been tried.
- The person: capacity, what they have been told, what they want and why.
- Who else is involved, and what has already happened: a local policy, an earlier concern, a senior already told.
- Your own position: how certain you are, and what is within your competence.
Clarifying is not stalling
A clarifying question earns its place only if the answer would change what you do. “How old is the patient?” is real when capacity is in play and dead weight when it is not. If you cannot say why a fact matters, you are visibly buying time, and examiners hear it.
Move two — name the tension
A dilemma is hard because two things you ought to do cannot both be done in full. Say what those two are: a conflict between respecting autonomy and protecting an identifiable third party is one sentence, and it reframes the whole answer. Then list the stakeholders — the patient, the family, the colleague, the team, and future patients affected by the precedent. Candidates who name four stakeholders sound like clinicians; candidates who name one have not left their own point of view.
- Conflict of duties
- Two obligations that both genuinely apply and cannot both be honoured. Naming the conflict is the analytical move; choosing between them is the ethical one.
- Escalation
- Passing a concern to someone senior enough to act. The GMC asks doctors to raise patient-safety concerns even when unsure, so it is expected rather than disloyal.
- Proportionality
- Doing the least intrusive thing that achieves the aim — why a quiet word can be the right first step, and a formal report right when it is not enough.
Move three — explore the options, including the hidden one
Dilemmas are posed as a binary: tell or do not tell, report or stay quiet, treat or respect the refusal. The binary is part of the test. Lay out the two obvious options, then ask what else is available, and for each say briefly what it achieves and what it costs.
The third option is usually a conversation
When a scenario looks binary, ask who you have not yet spoken to. Speak to the person directly before escalating. Ask a senior, a pharmacist, the safeguarding lead. Go back to the patient and explain what worries you. The better move is almost always more communication before more action.
Move four — take a position you can defend
With about a minute left, stop exploring and commit. Say what you would do, in order, and give the reason in one line. Then add the humility, which is a scoring move rather than a softener: name the fact that would flip you, and name the limit of your authority. Nobody expects a candidate to make a consultant’s decision.
Balance is not fence-sitting
The commonest way to lose an ethics station is to weigh both sides beautifully and then decline to choose. “There are good arguments either way and it depends on the situation” is not balance, it is an unfinished answer, and it reads as an unwillingness to be accountable. A position held with stated reservations always outscores no position at all.
A worked example, move by move
Here is a station run at the pace you would actually run it. The prompt: you are a final-year medical student on placement, the foundation doctor you are shadowing arrives an hour late and seems unsteady, and you can smell alcohol on his breath. What do you do?
Move one, clarify and gather. “First, how certain am I — a smell can have other causes, so I would describe what I noticed rather than assert he has been drinking. Second, and most urgently, has he started work today: prescribed anything, seen anyone, made any decisions? Third, has anyone else noticed, and has this happened before? Fourth, what do the trust and my medical school expect of a student with this concern?”
Move two, name the tension. “My duty to patients on the ward today is immediate, because an impaired doctor can cause serious harm in a single prescription. Against that sits what I owe a colleague: dependence is a health problem rather than simply misconduct, and an accusation that turns out to be wrong could follow him for years. The people affected are the patients he is about to see, the doctor himself, the team who would cover, and his future patients if nobody ever addresses this.”
Move three, explore the options. “This looks like a choice between saying nothing, which is not available to me, and reporting him formally. There are others. I could speak to him quietly away from the ward. I could tell the nurse in charge, who can make sure he is not left deciding alone. I could go to the registrar or my clinical supervisor. Whichever route I take, one thing has to happen regardless: he should not be prescribing today.”
Weighing move three: how to raise it
Speak to him first
- It treats him as a colleague with a possible health problem, which is how the profession asks that dependence be viewed.
- You may be wrong about the cause, and a private question costs little if you are.
- It gives him the chance to stand himself down, which is the outcome you want.
Escalate straight away
- A challenge from a student is easy to deflect and hard to follow through alone.
- It delays the only urgent thing: that he stops making clinical decisions today.
- A senior can arrange cover at once and is better placed to route it as a health concern rather than a disciplinary one.
Move four, take a position. “On balance, if he is not about to see a patient, I would speak to him first — briefly, privately, describing what I noticed rather than accusing him. Then I would tell the registrar the same day whatever he says, framed as a concern about a colleague’s health rather than a complaint, because patient safety today is not something a student and a foundation doctor can settle privately. What would change my mind is timing: if he were about to prescribe, I would skip the conversation and tell the nurse in charge at once. That is also where my role ends. I am not the person who investigates this, only the one who makes sure the right people know.”
That takes about three minutes. It claims no certainty it does not have, names the conflict, finds three options the prompt did not offer, and ends with a decision, a reason and a condition that would change it. Behind it sits the GMC position that doctors must act promptly if patient safety is or may be seriously compromised, and should raise a concern even when they are not certain — an expectation that reaches students through their medical school as well.
Timing, signposting and thinking aloud
Most MMI circuits run stations of roughly five to eight minutes, often with a minute or two outside the door to read the prompt, though the variation between schools is real and worth checking in your invitation. The failure mode is always the same: three minutes on move one, no position at the end.
Use the reading time to run the four moves silently, jotting two words per move if paper is provided. Inside, aim for something like thirty seconds clarifying, a minute on the tension, ninety seconds on options and forty-five seconds landing. Signposting each move costs three seconds and makes the answer feel controlled.
- “There are two competing principles here; let me take each in turn.”
- “Before I answer, there are two things I would want to know.”
- “Let me come to a position, and then say what would change it.”
Thinking aloud goes wrong when you narrate your uncertainty instead of your reasoning. One idea per sentence, finish the sentence you started, and let a silent two-second pause do the work that “um” does badly. If you are circling, say so and move on. There is more on this in structuring answers under pressure.
A 15-year-old asks you for the contraceptive pill and does not want her parents told. Talk me through your thinking.
Clarify first: does she understand the advice, is there any sign of coercion or a much older partner, has anyone discussed protection and testing. Name the tension: her confidentiality and developing autonomy against a safeguarding duty. Options: encourage her to tell a parent without making it a condition; provide contraception if she is Gillick competent and the Fraser criteria are met; involve safeguarding if warning signs appear. Then land it — on those conditions I would provide it, while pressing her to involve an adult, because confidentiality is what brings young people through the door at all. Both tests are set out properly in consent and capacity.
When you genuinely do not know
You will meet a scenario where you do not know the law, cannot recall the guidance, or have never thought about the situation. That is survivable, because the station tests reasoning and honesty rather than recall.
Do three things. Say what kind of problem it is, which shows you have placed it even if you cannot settle it. Reason from a principle rather than a rule you half-remember. Then say what you would do in practice — ask someone senior, check the local policy, look the guidance up. That is the honest professional answer, not an evasion.
What you must not do is invent. A confidently misquoted statute is worse than admitting uncertainty, because it tells an examiner you would do the same on a ward. “I am not certain of the exact legal position, but the principle I would work from is this” buys back credibility.
There is one intensive care bed and two patients who need it. How would you decide?
Start with what you would need to know: each patient’s likelihood of benefiting, whether the underlying problem is reversible, and what each of them wants. Then challenge the premise, because scarcity is often less fixed than the question implies — another unit or the on-call consultant may change the arithmetic. Name the pillar: this is justice, and the criterion UK practice works from is capacity to benefit rather than social worth. Age alone is not a criterion, though it may bear on how likely someone is to benefit, and that distinction is exactly what an interviewer is listening for. Then be honest about authority. The decision belongs to the intensivist on call with the referring team, against an agreed protocol.
The structure is portable. Resource allocation, artificial intelligence, assisted dying — the frontier topics later on this reading path are the same four moves with different content poured in. Drill them on the longer scenarios in the ethics guide until the moves run without you.
