Moral reasoning is the cognitive process individuals use to decide what is right and wrong. It is the internal justification that precedes a choice, where a person evaluates a situation against personal values and societal norms. This step involves considering the ethical dimensions of an action instead of acting on impulse. People use this process to navigate their daily social lives and make personal, economic, or ethical choices.
Theories of Moral Development
Stage-based theories suggest our capacity for ethical thought matures over time. Psychologist Jean Piaget observed children’s thinking about rules, laying the groundwork for the field. Lawrence Kohlberg later developed a detailed framework proposing that moral development progresses through three levels, each containing two stages.
The first level is preconventional morality, where judgment is based on self-interest. In Stage One, “Obedience and Punishment,” behavior is driven by avoiding punishment. Stage Two, “Individualism and Exchange,” is characterized by a “what’s in it for me” mentality, where right behavior serves one’s own needs.
The second level, conventional morality, centers on adherence to social rules. Stage Three, “Good Interpersonal Relationships,” involves making decisions to gain social approval. Stage Four, “Maintaining the Social Order,” expands this to obeying laws and respecting authority to maintain a functioning society.
The final level is postconventional morality, where individuals develop their own abstract principles of ethics. In Stage Five, “Social Contract and Individual Rights,” people understand that laws are social agreements that can be changed if they infringe on universal rights. Stage Six, “Universal Principles,” involves following internalized principles of justice, even if they conflict with laws. An individual at this stage acts on a moral compass, believing in concepts like the equality of all human beings.
Psychologist Carol Gilligan critiqued Kohlberg’s model for prioritizing a justice-based perspective, which she observed more commonly in males. She proposed a complementary “ethic of care” that emphasizes interpersonal relationships, compassion, and responsibility for others. This perspective suggests moral reasoning can also be grounded in protecting and caring for those with whom we have relationships. It offers a different, not necessarily less developed, approach to ethical dilemmas.
Influential Factors on Moral Judgments
Several immediate factors shape moral judgments, explaining why people reason differently in specific situations. These influences can be internal, such as emotion, or external. Feelings like empathy, guilt, disgust, or anger can steer or override logical analysis in a moral dilemma.
Psychologist Jonathan Haidt’s social intuitionist model suggests moral judgments are often the result of quick, automatic intuitions. Deliberate reasoning then occurs after the fact to justify the initial gut reaction. This means an emotional response can be the primary driver of a moral choice. For example, empathy might compel a person to help someone without a rational cost-benefit analysis.
Social and cultural contexts provide a framework for moral reasoning. The norms, values, and religious beliefs of a community define acceptable behavior. Peer groups and societal expectations also exert pressure to conform to shared moral standards. An individual’s personal experiences also play a part, as past events shape their moral framework.
The Brain’s Role in Morality
Moral reasoning is rooted in the brain’s biological functions. Neuroscientists have identified a network of regions that process ethical dilemmas by integrating rational thought and emotional responses. This shows that morality results from a complex interplay of different neural systems, not a single brain center.
The prefrontal cortex, particularly the ventromedial prefrontal cortex, is involved in rational deliberation, impulse control, and integrating emotions into decision-making. This area helps weigh the consequences of actions and align them with internal values. The amygdala is central to processing emotions like fear and empathy, generating rapid emotional signals that inform intuitive responses.
The insula contributes to moral feelings, particularly disgust, and becomes active when people face morally repugnant scenarios. This suggests it helps signal that something is morally “wrong.” The coordinated activity of these regions allows the brain to process the complex information in a moral choice, from social context to emotional response and deliberation.
Moral Reasoning in Practice
The Heinz Dilemma, a scenario used by Kohlberg, illustrates these concepts. A man named Heinz must decide whether to steal an overpriced drug to save his dying wife. The druggist is charging ten times the drug’s cost and will not lower the price, and Heinz can only gather half the amount.
An individual at the preconventional level might reason that Heinz should not steal the drug to avoid jail, or that he should steal it so his wife will be grateful. A person at the conventional level might argue against stealing because it is against the law and social order. Alternatively, they might argue he should steal it because a good husband is expected to protect his wife.
Someone at the postconventional level would reason based on abstract principles. They might conclude that Heinz should steal the drug because the right to life is more fundamental than the right to property. This decision would be based on a universal ethical principle, even if it means breaking the law.
