DSST Ethics in America common mistakes
DSST Ethics in America · Understand the traps and how to avoid them.
Treating the exam as a memorization test of philosopher names and '-isms' - matching a quotation or scenario to 'Kant' or 'utilitarian' and stopping there, without identifying the specific principle (categorical imperative, greatest happiness principle) that decides the case.
Prep guides and flashcards emphasize vocabulary, so candidates rehearse labels rather than the reasoning that distinguishes closely related positions (e.g., act vs. rule utilitarianism, Kantian duty vs. Rossian prima facie duty). The exam's scenario items reward applying the principle, not naming it.
What to do instead
For each major theory, write a one-sentence decision procedure you can apply mechanically (e.g., 'Kant: universalize the maxim; if it cannot be consistently willed as universal law, the action is impermissible'). Practice running three unfamiliar scenarios through each procedure and stating which feature of the scenario triggers the verdict.
Reading a scenario and answering from personal moral intuition or workplace convention instead of from the theoretical framework the question names or implies.
Most adults have settled moral habits, and the exam's scenarios sound like ordinary life. Candidates unconsciously substitute 'what I would do' for 'what a utilitarian/contractarian/virtue ethicist would conclude,' producing answers that feel right but don't match the requested lens.
What to do instead
Before choosing, underline the theory or question stem cue ('according to', 'from a Kantian perspective', 'a virtue ethicist would say'). If no theory is named, identify what the question is actually testing - a concept (e.g., informed consent, conflict of interest) rather than a personal judgment. Answer only through that lens, even when you disagree with it.
Confusing related but distinct concepts - conflating ethical relativism with ethical subjectivism, egoism with utilitarianism, negative and positive rights, or act and rule utilitarianism - and choosing the near-miss option.
These pairs share vocabulary and are often taught together, so the distinctions blur under time pressure. Distractor options are deliberately built from the adjacent concept, making the near-miss feel familiar and correct.
What to do instead
Build a two-column contrast sheet for each confusable pair with a one-line differentiator and a concrete example (e.g., 'cultural relativism: rightness fixed by a group's norms; subjectivism: fixed by an individual's approval'). Drill by writing the differentiator from memory, then checking.
Ignoring the metaethical and normative/descriptive distinction - treating a descriptive claim about what people believe or do as if it settled a normative question about what they ought to do.
The is/ought gap is easy to state and easy to miss in application. Questions that describe a practice ('most societies permit X') invite the natural but fallacious inference that X is therefore morally acceptable.
What to do instead
Flag any answer option that moves from 'is' to 'ought' without a bridging premise. Practice identifying the exact sentence where the inference occurs, and prefer options that supply an explicit normative principle or acknowledge the gap.
Applying a single principle in isolation when the scenario clearly involves competing values (e.g., autonomy vs. beneficence, loyalty vs. honesty) and answering as if only one mattered.
Candidates learn principles one at a time and look for the 'key' principle, missing that many items test recognizing and weighing a conflict. The best answer often names the conflict and a justified resolution rather than maximizing one value.
What to do instead
For each scenario, list at least two principles in tension before reading the options. Then evaluate options by whether they acknowledge the tension and justify a priority, rather than by whether they maximize a single value.
Skipping or rushing the reading of answer stems that contain qualifiers - 'best', 'most likely', 'except', 'primarily', 'necessary rather than sufficient' - and selecting a true statement that doesn't answer the question asked.
Exam items often include several factually true options; the discriminator is the qualifier. Under time pressure, candidates match on content and overlook the logical operator in the stem.
What to do instead
Circle or mentally bold the qualifier before evaluating options. For 'except' and 'not' items, restate the stem in positive form. Eliminate any option that is true but non-responsive to the specific question.
Treating applied-ethics cases (medicine, business, law, journalism, research) as generic 'be a good person' questions, missing the governing professional norm - informed consent, fiduciary duty, confidentiality limits, conflict-of-interest disclosure, authorship criteria.
Candidates without professional background default to common-sense morality, but applied items hinge on domain-specific standards where the intuitive answer (e.g., 'tell the family everything') conflicts with the governing rule (confidentiality).
What to do instead
Memorize a short list of core applied norms per domain and the standard exceptions (e.g., consent requires capacity, disclosure, voluntariness; confidentiality yields to imminent harm). Practice classifying each scenario by domain first, then applying that domain's norm.
Misreading the direction of a philosopher's argument on a specific issue - attributing to a thinker a position they explicitly rejected (e.g., reading Kant as a consequentialist, Mill as endorsing any pleasure without quality, Hobbes as denying all moral constraints).
Summary-level knowledge flattens nuance, and distractor options are crafted from common oversimplifications. Candidates recognize the name and pick the option that sounds most familiar rather than most accurate.
What to do instead
For each major figure, record one position they are known for and one common misattribution to reject. Verify by recalling a supporting argument, not just a label, before choosing an option that names a thinker.
Failing to distinguish the question's level of analysis - individual action, institutional policy, or public law - and applying an interpersonal-ethics answer to an institutional-design question.
Cases about corporate policy, regulation, or distributive justice require structural reasoning (incentives, rules, rights), but candidates default to interpersonal judgments about individual character. The mismatch produces plausible but off-target answers.
What to do instead
Label each item's level before answering: individual, institutional, or societal. Match the reasoning mode accordingly - character and intention for individuals, rule design and incentive analysis for institutions, justice and rights for public policy.
Poor time and item-management behavior: over-investing in one hard scenario, leaving later items unanswered, or changing correct first answers without a principled reason during review.
Scenario items are long and invite rumination; anxiety about a single ambiguous item consumes time budgeted for easier points. Review-phase second-guessing often replaces a correct reading with a hasty alternative.
What to do instead
Set a per-item time cap and move on, flagging hard items for return. On review, change an answer only when you can articulate a specific misreading or missed qualifier - not merely because the option 'looks better.' Practice with timed full-length sets to calibrate pace.
