Ethics
Moral Luck
When fortune affects moral judgment — different outcomes from same actions
Moral luck is the philosophical issue that we judge people morally based on factors outside their control. Famous example: drunk driver who hits no one vs drunk driver who kills child — same recklessness, very different judgment. Posed by Bernard Williams and Thomas Nagel (1976). Types of moral luck: (1) Resultant — outcomes of actions. (2) Circumstantial — what situations face you. (3) Constitutive — character one happens to have. (4) Causal — events leading to action. Tension: traditional view says we're responsible only for what we control (Kant); but practice often differs. Active issue in ethics.

- Settled question. Active philosophical debate.
- Simple difference of theories. Cuts across theories.

Frequently asked questions
What's moral luck?
Common pattern in moral judgment. We judge people based on factors outside their control. Outcomes affect judgment of action even when actor's control was identical. Suggests: control isn't only basis for moral assessment — luck matters. Tension with: rational ethics requiring only what's in one's control.
What's the drunk driver case?
Two drunk drivers. Both equally drunk, equally reckless. One drives home safely (no one in road). Other hits and kills child (child stepped in road). Same recklessness; same control over situation. But: the second driver judged much more harshly. Same action; different luck. Explains: "moral luck" — luck affecting moral assessment.
What are the types?
Four types. (1) Resultant: outcomes of one's actions. Drunk driver case. (2) Circumstantial: situations one faces. Person who'd never collaborate with Nazis but lives in nation that's spared invasion vs one who is occupied. (3) Constitutive: character one has. Personality traits not chosen. (4) Causal: causes leading to action. Background factors creating one's situation.
How does it conflict with Kantian ethics?
Kant: moral worth independent of consequences. Only matters whether you act from duty. Luck doesn't affect moral status. Moral luck challenges: in practice, we judge based on results. Successful murderer worse than failed attempt (even if same intent). Actual moral judgment includes luck. Tension between: pure Kantian theory and reality.
How does utilitarianism handle it?
Utilitarianism focuses on outcomes. Outcomes determine moral worth. Lucky outcomes good; bad outcomes bad. Doesn't distinguish: lucky vs deserved outcomes. But: also problematic — doesn't capture that successful and unsuccessful murderer differ only in luck, not in moral makeup. Both: blameworthy attempters? Or different?
What's the practical implication?
Justice systems vary. Most: punish more severely for completed crimes than attempts. Even with identical intent. Reflects belief that outcomes matter. But also: punishment varies by control. Mens rea (mental state) considered: deliberate vs negligent. Combining outcomes and control: complex. Moral luck shows: pure moral theory underdetermines actual judgment.
How is it active issue?
Active debate. (1) Some philosophers: bite bullet — moral luck is real; control isn't only thing. (2) Others: distinguish moral assessment of action from assessment of agent. Action affected by luck; agent isn't. (3) Practical implications: criminal justice, regret, gratitude, blame. Connections to free will: similar issues with control over circumstances.
