09/10 Introduction to Applied Ethics
A structured guide to applying moral reasoning and major ethical frameworks to concrete decisions involving rights, consequences, character, justice, privacy, technology, professional duties, punishment, and the environment.
The Scope of
evaluates concrete choices, policies, institutions, professions, and technologies. It asks more than whether an action is legal or socially accepted. A complete analysis considers:
Who may be affected, including vulnerable groups, future generations, and the wider community.
Which duties, rights, and responsibilities apply.
What benefits and harms are likely.
Which values conflict and how the conflict might be resolved.
What kind of person or institution a decision encourages us to become.
differs from descriptive ethics, which studies what people believe, and metaethics, which examines the meaning and status of moral claims. It belongs to normative ethics because it evaluates conduct, policies, and institutions according to standards of rightness, wrongness, justice, or human flourishing.
Law and ethics overlap but are not identical. Law establishes enforceable public rules, while ethics asks whether conduct is justified. An action can be legal but unethical, or illegal yet morally defensible in exceptional circumstances. Legal requirements are important constraints, but they do not always settle the moral question.
Takeaway: turns abstract moral concerns into structured evaluation of real situations.
The Three Major Ethical Frameworks
Three major frameworks emphasize different aspects of a moral decision.
asks which available option produces the best overall outcome. It weighs benefits, harms, probabilities, and long-term effects. Its strengths include attention to public welfare and preventable harm. Its risks include sacrificing an individual for a larger benefit, undervaluing rights, or relying on uncertain predictions.
asks what must or must not be done according to duties, rights, and principles. It protects dignity, consent, fairness, and individual rights. Its challenges include conflicting duties and rules that may be too rigid in unusual circumstances.
asks what a good and practically wise person would do. It focuses on character, motivation, habits, and human flourishing. Its challenges include disagreement about virtues and a lack of precise rules for every conflict.
The frameworks can be compared by their central questions:
: Which option produces the best overall outcome? Its main focus is benefits, harms, and welfare; a typical danger is sacrificing rights or minorities.
: What must or must not be done? Its main focus is duties, rights, and principles; typical dangers include rigidity and conflicting duties.
: What would a good and practically wise person do? Its main focus is character and flourishing; typical dangers include vagueness and cultural disagreement.
These frameworks are not mutually exclusive in ordinary reasoning. A strong analysis can use consequences to assess effects, duties to identify limits, and virtues to evaluate motives and institutional culture. If frameworks reach different conclusions, the disagreement should be explained rather than hidden.
Takeaway: Use several frameworks because each reveals moral features that the others may overlook.
A Method for
is practical reasoning about what one ought to do. It is not merely expressing a preference; it requires reasons that can be examined and communicated.
A disciplined process is:
State the moral problem. Express the conflict clearly rather than as a vague feeling.
Gather relevant facts. Separate verified information from assumptions, forecasts, and disputed claims.
Identify stakeholders. Include directly and indirectly affected people, vulnerable groups, future generations, and the wider community.
List realistic options. Consider delay, partial implementation, oversight, compensation, safer alternatives, and refusal as well as the obvious choices.
Identify values and constraints. Consider welfare, autonomy, , , dignity, justice, trust, professional duties, and environmental responsibility.
Apply several frameworks. Examine each option through consequences, duties and rights, and virtues.
Consider proportionality. Ask whether expected benefits justify the burdens and whether a less restrictive alternative exists.
Check consistency and reversibility. Ask whether the reasoning would remain acceptable if roles were reversed or the decision became public.
Reach a provisional conclusion. State the strongest reasons, acknowledge uncertainty, and identify safeguards.
Review and revise. Monitor outcomes because new evidence or unintended effects may change the judgment.
Takeaway: Good ethical reasoning makes facts, assumptions, stakeholders, options, values, and safeguards visible before reaching a conclusion.
Comparing Options in Practice
Consider a school deciding whether to use facial-recognition software to identify unauthorized visitors.
A consequentialist analysis asks whether increased safety outweighs false matches, surveillance, and chilling effects.
A deontological analysis asks whether students and visitors were informed, whether consent or legal authority exists, and whether and due process are respected.
A virtue-ethical analysis asks whether adoption reflects prudence, respect, responsibility, and concern for vulnerable students.
A structured judgment compares less intrusive alternatives, such as staffed entrances and temporary visitor badges. If an alternative provides comparable safety with fewer risks, proportionality may favor that option.
The example illustrates why ethical evaluation should not begin with technological possibility alone. It should compare realistic alternatives and examine who bears the risks, who receives the benefits, and whether affected people can challenge the decision.
The same reasoning applies to automated traffic cameras. Their use might be supported if they substantially reduce injuries, but only alongside safeguards against false accusations, unequal enforcement, and unnecessary data collection.
Takeaway: A defensible decision is often the option that meets the legitimate goal while imposing the fewest unjustified burdens.
Ethics in Public, Professional, and Environmental Life
can be used across major areas of public and professional life.
Punishment: Ask whether responsibility and guilt have been established through fair procedures, whether the punishment is proportionate, whether it prevents future harm or supports rehabilitation, whether similar cases are treated alike, and whether less harmful responses are available. Consequentialist approaches emphasize deterrence, incapacitation, rehabilitation, and public safety. Retributive approaches emphasize proportional desert, while abolitionist approaches question whether punishment should be replaced by other forms of accountability.
: Determine whether collection is necessary, understandable, proportionate, and fairly used. Limit data to the stated purpose, protect it from misuse, give meaningful notice and choices, and establish retention and deletion rules. An employer may need an emergency contact without needing an employee's continuous location history.
and justice: Distinguish formal , substantive , of opportunity, and proportional fairness. Treating everyone identically is not always fair when people begin from unequal conditions. When assessing an algorithm for hiring, lending, education, or criminal justice, examine historical discrimination, differences in error rates, opportunities to challenge decisions, and the distribution of benefits and burdens.
: Professionals should act with competence, honesty, confidentiality, transparency about risks, accountability, and concern for serious harm. Employer instructions do not eliminate personal responsibility when a design is unsafe, discriminatory, deceptive, or -invasive. A professional should document concerns, seek review, propose safer alternatives, and escalate serious issues when necessary.
: Evaluate systems across their entire life cycle, including research, data collection, design, testing, deployment, monitoring, maintenance, and retirement. Ask whether they respect dignity, protect , avoid discrimination, provide transparency, permit accountability and human oversight, manage foreseeable failures, and limit environmental effects.
Environmental obligations: Consider sustainability, climate change, biodiversity, pollution, nonhuman life, and future generations. Examine a product or policy's full life cycle, from extraction and manufacture through use and disposal, and identify which communities receive benefits or bear risks.
Takeaway: The same core questions—who is affected, what is owed, what consequences follow, and whether burdens are fairly distributed—apply across different ethical domains.
A Reusable Ethical Analysis Template
Use this template when writing or discussing an ethical problem:
Issue: What precise moral question must be answered?
Facts: What is known, unknown, uncertain, or disputed?
Stakeholders: Who may gain, lose, or be exposed to risk?
Options: What realistic courses of action are available?
Values: Which rights, duties, consequences, virtues, and justice concerns apply?
Framework analysis: What does each major ethical theory recommend, and why?
Objections: What is the strongest argument against the proposed decision?
Safeguards: How can harm, bias, loss, or unequal burdens be reduced?
Conclusion: Which option is best justified, and under what conditions?
Review: What evidence would require the decision to be changed?
This structure prevents one consideration—such as profit, convenience, tradition, or technological possibility—from dominating without justification. It also makes uncertainty and conditions explicit, allowing an ethical decision to be monitored and revised.
Final takeaway: Responsible combines careful facts, stakeholder awareness, multiple frameworks, proportionality, , accountability, and willingness to revise a judgment when its effects or supporting evidence change.
