The Trolley Problem: Dilemmas in Moral Decision-Making


The Trolley Problem: An Ethical Quandary

The Trolley Problem is a thought experiment in ethics that explores the moral dilemmas inherent in decision-making. It presents a hypothetical scenario where a trolley is headed towards a group of five people tied to the tracks. You have the ability to change the trolley’s course by pulling a lever, but doing so would divert it towards another track where there is a single person tied up. The question is whether it is morally acceptable to sacrifice one person to save five.

This ethical quandary highlights the tension between different ethical frameworks. Utilitarianism, for example, would argue that the morally right action is the one that maximizes overall happiness or utility. From this perspective, diverting the trolley to save five lives would be the morally correct choice, as it would result in the greatest overall happiness.

On the other hand, deontological ethics, which focuses on the inherent rightness or wrongness of actions, might argue against sacrificing one person for the greater good. According to this perspective, certain actions, such as intentionally causing harm to an innocent person, are inherently morally wrong regardless of the consequences.

The Trolley Problem also raises questions about personal moral responsibility. If you choose to pull the lever and divert the trolley, you are actively causing the death of one person. However, if you choose not to act and allow the trolley to continue on its original course, you are passively allowing the deaths of five people. Both choices have moral implications, and the decision is often seen as a reflection of an individual’s personal values and ethical beliefs.

Overall, the Trolley Problem serves as a thought-provoking exploration of the complexities of moral decision-making. It challenges us to consider the trade-offs between different ethical frameworks and the weight we place on individual lives versus the greater good. While there may not be a clear-cut answer, contemplating these ethical dilemmas can help us refine our own moral compass and better understand the complexities of the human experience.

Understanding the Trolley Problem

The trolley problem is a thought experiment in ethics that presents a moral dilemma regarding the consequences of one’s actions. It forces individuals to consider a scenario where they have to make a decision that will result in harm to others, but with the intention of minimizing overall harm. The problem is typically presented as follows:

  • A trolley is running out of control on a track.
  • There are five people tied to the track ahead and they will be killed if the trolley continues on its current path.
  • However, you have the ability to divert the trolley onto a different track.
  • On this alternate track, there is only one person tied up, but diverting the trolley will result in that person’s death.

This ethical dilemma raises questions about the nature of moral decision-making and the value of individual lives. It explores the conflict between utilitarianism, which prioritizes the greater good for the majority, and deontological ethics, which emphasizes the importance of following moral rules and principles.

Those who advocate for a utilitarian perspective argue that it is morally justifiable to divert the trolley onto the alternate track, sacrificing one life to save five. They believe that the outcome with the least harm is the most ethical choice.

On the other hand, proponents of deontological ethics argue that intentionally causing harm, even with good intentions, is morally wrong. They believe that the act of diverting the trolley would be a violation of the moral principle that prohibits directly causing harm to others.

The trolley problem forces individuals to confront the complexities of moral decision-making and challenges them to consider the consequences of their actions. It highlights the intricate balance between the greater good and individual rights, creating a dilemma that has no easy or universally agreed-upon solution.

Exploring the Moral Implications

When exploring the moral implications of the trolley problem, several key considerations arise. These considerations revolve around the principles of utilitarianism, deontology, and virtue ethics.


  • One perspective is to approach the trolley problem from a utilitarian standpoint, where the moral choice is determined by maximizing overall happiness or minimizing overall harm.
  • In this context, pulling the lever to divert the trolley to kill one person instead of five could be seen as the morally preferable choice, as it results in the least amount of overall harm.
  • However, this viewpoint raises ethical concerns about treating individuals as mere means to an end, as it involves sacrificing the life of one for the greater good.


  • An alternative perspective is to analyze the trolley problem through the lens of deontological ethics, which focuses on the inherent rightness or wrongness of actions.
  • From a deontological standpoint, pulling the lever to divert the trolley may be considered morally wrong, as it involves actively causing harm to an innocent person.
  • Deontologists argue that certain moral duties, such as the duty to respect the sanctity of life, should never be violated regardless of the consequences.

Virtue Ethics:

  • Virtue ethics provides another perspective to consider when examining the moral implications of the trolley problem.
  • This ethical approach focuses on the development of moral character and the cultivation of virtues, such as compassion and justice.
  • In the context of the trolley problem, a virtuous person may choose not to pull the lever, as they prioritize the principles of non-violence and respect for human life.

Overall, the trolley problem presents a complex moral dilemma that elicits different responses based on one’s ethical framework. It challenges individuals to grapple with the conflicting values of utilitarianism, deontology, and virtue ethics, ultimately highlighting the complexities of moral decision-making.

The Role of Utilitarianism in Decision-Making

Utilitarianism is a moral theory that plays a significant role in decision-making, particularly in ethical dilemmas such as the trolley problem. It focuses on maximizing overall happiness or well-being for the greatest number of people. In this context, utilitarianism suggests that the morally right action is the one that produces the greatest amount of happiness or the least amount of suffering.

One way to apply utilitarianism to the trolley problem is by examining the consequences of each possible action. For example, if pulling a lever would divert the trolley to a different track and save five people at the expense of one person, utilitarianism would argue that pulling the lever is the morally right action. This is because it would result in a net increase in overall happiness by saving five lives at the cost of one.

Utilitarianism also takes into account the idea of impartiality. It does not prioritize the interests or well-being of a particular individual or group over others. Instead, it considers the well-being of all individuals equally. In the trolley problem, utilitarianism would not differentiate between the lives of the five people on the main track and the one person on the side track. It would focus solely on the overall consequences and the number of lives saved.

However, utilitarianism does raise some ethical concerns. Critics argue that it may lead to the violation of individual rights or the sacrifice of certain individuals for the greater good. Additionally, it may not adequately consider the intrinsic value of human life or other moral considerations beyond happiness and suffering.

In conclusion, utilitarianism provides a framework for decision-making in moral dilemmas like the trolley problem. It prioritizes the maximization of overall happiness or well-being and promotes impartiality. While it has its limitations and ethical concerns, utilitarianism offers a logical approach to navigating complex moral decisions.

Critiques of Utilitarian Ethics

Utilitarian ethics, which prioritize the greatest good for the greatest number of people, have faced several critiques over the years. These critiques challenge the fundamental principles and assumptions of utilitarianism in the context of moral decision-making, including the trolley problem.

One major critique of utilitarian ethics is the objection that it fails to respect individual rights and autonomy. Critics argue that utilitarianism can lead to outcomes where the rights of a few are sacrificed for the greater good. In the case of the trolley problem, this criticism suggests that utilitarianism may justify actively causing harm to an innocent individual in order to save a larger number of people.

Another critique points out that utilitarianism focuses solely on the consequences of actions, neglecting the intentions or motives behind them. Critics argue that this approach can lead to morally questionable decisions, as it overlooks the importance of individual moral agency and the distinction between accidental and intentional harm. In the context of the trolley problem, this criticism suggests that utilitarianism may not adequately consider the moral significance of intentionally causing harm to someone, even if the overall outcome is beneficial.

Additionally, some critics argue that utilitarian ethics can lead to a form of moral relativism, where the ends justify the means. This objection raises concerns about the potential for utilitarianism to justify actions that are otherwise considered morally wrong, as long as they produce the greatest overall happiness or utility. In the trolley problem, this critique suggests that utilitarianism may overlook the inherent value of certain moral principles or rules, such as the prohibition against intentionally killing an innocent person.

Furthermore, opponents argue that utilitarianism fails to adequately account for the complexity and uniqueness of moral situations. Critics claim that the utilitarian framework oversimplifies moral decision-making by reducing it to a quantitative calculation based on aggregate outcomes. This criticism asserts that ethical dilemmas like the trolley problem require a more nuanced approach that considers individual relationships, context, and the inherent value of human life.

In conclusion, utilitarian ethics, including their application to the trolley problem, have faced significant critiques regarding their potential disregard for individual rights, intentions, moral absolutes, and the complexity of moral decision-making. While utilitarianism offers a systematic approach to moral reasoning, these criticisms highlight the need for a more comprehensive ethical framework that considers multiple dimensions of moral value and individual agency.

Deontological Perspectives on the Trolley Problem

Deontological perspectives on the trolley problem provide a framework for analyzing the moral decision-making involved in this ethical dilemma. Deontological ethics, often associated with philosophers such as Immanuel Kant, focuses on the inherent moral duties and principles that guide our actions, rather than the consequences of those actions.

According to deontological perspectives, the moral rightness or wrongness of an action is determined by whether it conforms to certain moral rules or duties. In the context of the trolley problem, deontologists consider the principles that should guide our decision-making when faced with the choice to sacrifice one life to save many.

One common deontological perspective is the principle of nonmaleficence, which holds that we have a duty not to harm others. From this perspective, pulling the lever to divert the trolley and save five lives would be seen as morally permissible, as it avoids actively causing harm to others. However, pushing the large person onto the tracks to stop the trolley would be seen as morally impermissible, as it involves actively causing harm to one person.

Another deontological perspective is the principle of beneficence, which holds that we have a duty to promote the well-being of others. From this perspective, both actions in the trolley problem could be seen as morally impermissible, as they involve intentionally causing harm to one person in order to save others. In this view, the ends do not justify the means, and it is our duty to refrain from causing harm to others, regardless of the potential benefits.

Deontological perspectives also emphasize the importance of respecting the autonomy and dignity of individuals. From this perspective, any action that involves treating one person solely as a means to an end would be seen as morally impermissible. This would include both pulling the lever and pushing the large person onto the tracks, as they involve using individuals as mere instruments to achieve a desired outcome.

Overall, deontological perspectives on the trolley problem provide a valuable lens through which to analyze the moral decision-making involved in this ethical dilemma. By considering principles such as nonmaleficence, beneficence, and respect for autonomy, we can better understand the complex moral considerations at play and the different perspectives that individuals may have when faced with this challenging scenario.

Ethical Dilemmas in Real-World Scenarios

The Trolley Problem presents a series of ethical dilemmas that arise in real-world scenarios. These scenarios force individuals to make difficult moral decisions, often involving choosing between two or more conflicting courses of action. Here are some examples of the ethical dilemmas that individuals may encounter:

  • Scenario 1: A runaway trolley is heading towards five workers who are unaware of the danger. You have the option to pull a lever, diverting the trolley onto a different track where there is only one worker. What should you do?
  • Scenario 2: You are a doctor with five patients in critical condition. Each requires a different organ transplant to survive. A healthy patient walks into your clinic for a routine check-up. Should you sacrifice the healthy patient to save the lives of the five critically ill patients?
  • Scenario 3: A self-driving car is approaching a crosswalk, where a group of pedestrians is crossing. Suddenly, a child runs into the street, and the car has two options: hit the child or swerve into a wall, potentially harming the car’s occupants. How should the car be programmed to respond?

These scenarios pose complex ethical dilemmas as they involve weighing the value of human life, the principle of minimizing harm, and the responsibility of individuals or autonomous systems to make decisions that result in the greatest overall good. Different ethical frameworks, such as utilitarianism or deontology, may offer different perspectives on how to approach these dilemmas. Ultimately, the resolution of these dilemmas requires thoughtful consideration and discussion to determine the most ethical course of action.
