Introduction
This article analyzes the paradox of legal luck (moral luck), namely the conflict between the principle of responsibility for what we control and the intuitive desire to punish unlucky outcomes more severely.
You will learn why human psychology favors judging results over intentions and how modern law should filter these instincts through a constitutional lens.
The objective of this text is to demonstrate that the criminal justice system must serve as a barrier protecting the individual from state arbitrariness in situations where chance outweighs culpability.
Punishment as an Evolutionary Technology for Stabilizing Cooperation
Humans developed mechanisms of blame and sanction to counteract free-rider problems. Punishment serves to stabilize cooperation within groups by eliminating those who violate norms.
A key mechanism here is strong reciprocity, which is the willingness to incur costs to punish others, even without a direct material benefit.
Responsibility functions as a technology: it allows for the identification of agents capable of altering their behavior (reasons-responsiveness). An example of this is that we do not punish weather events, but people, as only humans respond to social reasons.
The Cultural Variability of Sanctions Precludes the Naturalization of Positive Law
The fact that humans have always employed punishment does not mean that current rules are naturally just. Anthropology reveals a vast diversity of sanction systems depending on the culture.
The evolutionary effectiveness of a mechanism is not synonymous with its moral correctness. Some norms persist merely due to path dependence or the reinforcement of specific groups' positions.
Therefore, positive law cannot be a simple copy of instincts. Mechanisms that stabilize cooperation can be cruel or unfair, necessitating external axiological verification.
Punitive Intuition as an Evolutionary Compromise, Not a Moral Norm
The tendency to punish outcomes more severely than intentions stems from a pragmatic compromise: while systems need the control principle to be fair, they react to results because the community is concerned with actual harm.
However, such intuition is not a measure of moral truth. It is susceptible to hindsight bias, where knowledge of a tragic outcome distorts the assessment of the perpetrator's guilt.
Modern law should treat these instincts as raw material for normative processing. Rather than mirroring emotions, the system must decouple the degree of culpability from the scale of damage to avoid transforming bad luck into moral degeneracy.
Summary
A state governed by the rule of law does not eliminate instances of legal luck, but it limits their influence on sentencing. The key is the transition from emotional retribution to a system based on reasons.
Constitutional filters—such as dignity, proportionality, and legality—protect the perpetrator from becoming a mere instrument in the hands of an authority seeking a deterrent effect.
The triumph of civilization lies in forcing the state to justify every day of incarceration, ensuring that bad luck does not become an automatic sentence.
Frequently Asked Questions
Why did humans develop mechanisms for punishing and blaming others?
Punishing and blaming mechanisms evolved as a technology of cooperation that allows for the stabilization of collaboration in groups by identifying norm-violators and eliminating so-called free-riders. This system serves to protect social rules and direct claims toward individuals capable of changing their behavior under the influence of sanctions.
Does the fact that humans have always applied sanctions and punishments mean that current rules of criminal liability are naturally just?
No, the fact that sanctions are applied does not mean that current rules of criminal liability are naturally just. Humans possess only a general capacity to create normative systems, whereas specific legal rules are variable cultural solutions that need not be optimal or fair.
Does the fact that people have always punished the outcome more severely than the intent itself mean that this is a just solution?
No, the persistence of this distinction does not prove its optimality or moral correctness, as it may result from legal convention or social functions. This practice may be a pragmatic compromise between assessing intention and reacting to actual harm; therefore, modern law should not uncritically copy spontaneous moral psychology.
Is the social sense of justice an independent measure of the fairness of the law, or can it be a product of the legal system itself?
The sense of justice can be a product of the legal system as a result of a feedback loop, where the law shapes future social preferences and intuitions. Consequently, the alignment of law with moral intuition does not have to be an independent confirmation of the correctness of norms, but rather the result of the shared history of both phenomena.
Why is the mere existence of evolutionary punishment mechanisms insufficient, and why do we need formalized criminal law?
Evolutionary punishment mechanisms are prone to abuse, as punishment can become a tool for status competition, jealousy, or control over competitors. Formalized criminal law introduces procedural barriers and judicial independence to prevent the use of sanctions for private gain and to avoid erroneously equating the outcome of an event with the characteristics of the perpetrator.
Does the fact that certain punishment mechanisms help stabilize social cooperation automatically make them just or correct?
No, the fact that punishment mechanisms help stabilize social cooperation does not automatically make them just or correct. Function explains the persistence of a given institution but is not sufficient to justify it; therefore, a functional norm always requires an additional normative test.
Why are law and moral intuitions alone insufficient for just punishment, and what mechanisms should supplement them?
Law and moral intuitions alone are insufficient because the mechanism of responsibility is not morally self-verifying and can serve to stabilize unjust norms or repression. They should be supplemented by meta-norms of responsibility (such as principles of control, proportionality, and legality) and empirical sciences, which curb arbitrariness and correct erroneous beliefs about how punishments work.
How should modern law address evolutionary mechanisms of punishment in the face of the luck paradox?
Modern law should subject evolutionary mechanisms of punishment to normative reconstruction, understanding their origin and preserving their functional achievements while simultaneously separating them from revenge. Instead of uncritically accepting intuitions, the legal system must tame its heritage by requiring justification for every punishment and applying principles of proportionality and guilt.
How can conflicting intuitions regarding harm and control be reconciled within a state-managed legal system?
A legal institution must be created that recognizes the reality of harm and requires responsibility, without simultaneously turning bad luck into moral degeneration or the perpetrator into an instrument. This system must be based on the theory of the legitimate scope of state power and the principles of constitutionalism, so that the infliction of hardship is consistent with respect for the citizen's dignity.
Why is the state's effectiveness in ensuring security alone not enough to justify the use of criminal sanctions?
Effectiveness in ensuring security alone is not enough because the state must possess the legitimate competence to use a specific tool, rather than merely be guided by a just goal. Criminal sanctions deliberately interfere with natural human entitlements, such as liberty or privacy; therefore, their application requires justification based on fundamental rights and human dignity, not solely on the efficiency of actions.
Why cannot the state increase punishment solely to achieve a deterrent effect, particularly in cases of legal luck?
The state cannot increase punishment exclusively for a deterrent effect because a person cannot be reduced to a mere carrier of such an effect, as this would violate their dignity. In the case of legal luck, additional hardship requires justification based on reasons concerning the specific individual, rather than solely on the social utility of the punishment.
How do constitutional principles, such as equality and legality, help resolve the problem of injustice resulting from the accidental outcome of an act?
The principle of equality mandates a justification for the choice of relevant characteristics when distinguishing between perpetrators, placing particular emphasis on the issue of arbitrary luck. In turn, the principle of legality protects against the retrospective change in the assessment of an act under the influence of hindsight bias, requiring that the perpetrator be judged according to rules established ex ante.
How do constitutional and procedural guarantees protect the individual from randomness and arbitrariness in criminal justice?
Constitutional and procedural guarantees, including the right to defense and an independent court, protect the individual from arbitrariness and unjustified deprivation of liberty. Through the proceduralization of inquiry, the state limits the influence of randomness (epistemic luck) on decisions regarding guilt, transforming the asymmetry of power into a relationship limited by reasons.
How can the legal system reconcile the need to respond to actual harm (luck) with the protection of the individual from arbitrariness and excessive repression?
The legal system can reconcile these needs through a two-level structure, in which constitutional rules and fundamental rights set inviolable boundaries of admissibility (e.g., dignity, proportionality), and only within those boundaries does the optimization of protective or remedial functions occur. Actual harm may influence the dimension of sanctions or remedial obligations; however, it must pass through a filtration process that verifies, among other things, the assignability of the result and the compliance of the interference with individual rights.
How should the state justify punishment for accidental outcomes in light of constitutional principles?
The state should justify punishment based on the principle of proportionality and penal minimalism, preferring less invasive measures if they achieve the same protective goal. In the case of factors beyond the perpetrator's control (legal luck), the burden of proving the necessity of a harsher sanction rests with the state, which requires distinguishing between the attribution of responsibility for the result and the magnitude of the imposed hardship.
How can modern law prevent an accidental event from turning into excessive, arbitrary state repression?
Law prevents arbitrary repression by filtering the functions of punishment through the prism of fundamental rights, the principles of proportionality and legality, and by treating punishment as an act of state self-binding. The criminal procedure plays a key role—including an independent court, the right to defense, and the presumption of innocence—which transforms the physical ability to imprison a person into a legally justified competence.
How can a legal system be organized to protect victims while simultaneously preventing the state from exercising excessive repression resulting from chance?
A two-layer model should be applied, in which the constitutional layer defines the boundaries of inadmissibility (e.g., the prohibition of arbitrariness and disproportionality), and the functional layer optimizes victim protection and damage repair. This system is based on the theory of bilateral responsibility, in which the state bears responsibility for the selection of sanctions and the criteria for attributing guilt, thereby preventing chance from being used against the individual.
How can the paradox of moral luck be resolved within a modern constitutional state?
The solution to the paradox of moral luck lies in the synthesis of realism with constitutionalism, leading to so-called constitutional domestication of luck. In this model, the rule of law must limit the cost of epistemic bad luck and apply rigorous justification when converting random outcomes into the legal burden of the perpetrator.
