Consequences and Duties: Two Lenses for Ethics Stations
When an ethics scenario feels obvious, you are about to give a shallow answer. Two competing lenses will generate the other side of the argument in about ten seconds.
The dangerous ethics prompt is not the hard one. It is the one that seems easy. You read it, the right answer is immediately obvious to you, and you walk in with ninety seconds of material for a two minute station and nothing to say when the assessor asks whether you can see it any other way.
What you needed was a way to manufacture the other side quickly, even when you do not personally believe it. Two lenses will do that, and they take about ten seconds each to apply.
The lenses, in plain terms
The consequences lens
Judge the action by what it brings about. Who is better off, who is worse off, by how much, and over what time frame. This is the lens behind most public health thinking, most resource allocation, and most sentences that begin with the greatest benefit.
Applied to a scenario, it asks: what actually happens next, in each version of this story, and to whom.
The duties lens
Judge the action by whether it honours obligations that hold regardless of outcome. Do not deceive people. Keep the promises you made. Do not use a person as a means to somebody else's benefit. Treat like cases alike.
Applied to a scenario, it asks: what did I undertake to do for this person, and would this action break something I am not entitled to break, even for a good result.
Why two lenses beat one framework
A framework like the four principles tells you what to look at. It does not generate an argument you had not already thought of. Two competing lenses do, because they are designed to disagree, and their disagreement is where the depth in your answer comes from.
That is why this is such a useful tool for the scenario that feels one sided. If your instinct is a consequences answer, the duties lens will hand you the objection immediately. If your instinct is a duties answer, the consequences lens does the same in reverse. You are no longer waiting for inspiration.
Running the switch in reading time
The mechanics are simple enough to do at a door with a prompt in your hand:
- Notice your instinctive answer and name which lens produced it.
- Deliberately apply the other one, and find the single strongest objection it raises.
- Write two words: your position, and the objection. That is your whole note.
- Plan to voice the objection yourself rather than waiting to be handed it.
- Decide which consideration you think outweighs the other, so you have an ending before you begin.
Raising the objection yourself is the move that matters. An assessor who has to supply the counterargument is testing you. An assessor who watches you supply it is marking you.
What the switch sounds like
Take a scenario where a patient asks you not to record something in their notes, and it feels obvious that you cannot agree. A consequences reading gets you there fast: incomplete records lead to worse care later, and other clinicians will make decisions without knowing something important.
Now switch. The duties lens asks what you owe this specific person, who told you something difficult on the understanding that you were on their side, and whether you made any implicit promise about how it would be handled. That gives you a real second half: the cost of recording it is not just their discomfort, it is the possibility that they stop telling clinicians difficult things at all, and there is a genuine obligation not to treat their disclosure carelessly.
Same conclusion, probably. Twice the answer, and an assessor who can see that you did not simply arrive with an opinion.
Where each lens breaks
Knowing the failure points of each lens is what stops you sounding like a first year philosophy student who has just discovered utilitarianism.
- Consequences reasoning can justify almost anything if you choose your time frame and your affected population conveniently.
- It also requires you to predict outcomes, and in most real scenarios nobody knows what will happen.
- It can quietly sacrifice one person for an aggregate gain, which is precisely what most people find intolerable in medicine.
- Duty reasoning can be rigid to the point of absurdity when following the rule produces obvious harm.
- It offers little guidance when two duties conflict directly, which is most of the interesting cases.
- It can be used to avoid responsibility for outcomes: I followed the rule, so the result is not mine.
Naming one of these limits inside your answer is a fast way to show that you are using the lenses rather than being used by them.
Should you say the words out loud
Mostly no. Saying that you will approach this from a consequentialist and then a deontological perspective adds nothing an assessor can mark, and it risks a follow up about a theory you have read one summary of. Do the reasoning and let the structure be visible in what you say rather than in the labels you attach to it.
Ordinary phrasing carries the same content: if I think about what actually happens to everyone involved, versus, if I think about what I owe this particular person regardless of how it turns out. That is the same move in language a patient could follow, which is the register medical schools are looking for anyway.
A third angle worth keeping
When both lenses feel unsatisfying, there is a third question that often unlocks a station: what would a good doctor do here, and what would this decision make me into if I made it repeatedly. It sounds soft and it is not. Character reasoning is how most experienced clinicians actually talk about difficult calls, and it gives you somewhere honest to go when the arguments are evenly balanced.
Format changes how you deploy this
In a short station you get one switch and one landing. In a longer conversation, which is closer to what a panel format allows, you can hold the tension for several minutes and let the interviewers push you across it. Our comparison of MMI and panel interviews in Australia covers that difference in pacing. Either way, check the university's current admissions page for the format they are actually running this cycle.
Drilling the switch
Take ten MMI ethical stations and, for each one, say your instinctive answer in one sentence and the strongest objection in one sentence. Twenty seconds per scenario, no full answers. You are training a reflex, not a speech.
Then put it back into full MMI circuit conditions under a clock, because the whole value of the switch is that it happens fast enough to leave you time to reach a position.
MasterMed's AI interviewer runs those stations timed and marks them against a rubric, including whether you genuinely engaged with the other side. The first speaking station is free on the trial, no card required, and the trial never converts on its own.
The point of the two lenses is not to make you sound philosophical. It is to make sure that the scenario you found obvious gets the same two minutes of real thought as the one you found hard.
