Logical Fallacies and Cognitive Biases
Tu Quoque Fallacy
• Definition: A fallacy that occurs when someone dismisses an argument by accusing the opponent of hypocrisy rather than addressing the substance of the argument.
• Example:
• Person A: “You shouldn’t smoke; it’s bad for your health.”
• Person B: “Well, you smoke, so why should I listen to you?”
• Strengths:
• Can expose hypocrisy in an opponent’s argument.
• Weaknesses:
• Does not actually refute the argument itself.
• Can distract from the main issue.
Slippery Slope Fallacy
• Definition: A fallacy that suggests that a small action will inevitably lead to a series of extreme and undesirable consequences without sufficient evidence.
• Example:
• “If we allow students to use calculators in class, soon they won’t be able to do basic math, and then they won’t be able to function in society at all.”
• Weaknesses:
• Assumes an exaggerated chain reaction without proof.
• Ignores possible safeguards against the extreme outcome.
Confirmation Bias
• Definition: The tendency to search for, interpret, and remember information in a way that confirms one’s preexisting beliefs while ignoring or downplaying contradictory evidence.
• Example:
• A person who believes in astrology only remembers the times their horoscope was accurate and ignores when it was wrong.
• Weaknesses:
• Can lead to poor decision-making by disregarding contrary evidence.
• Can reinforce misinformation.
Sunk Cost Fallacy
• Definition: The tendency to continue investing in a losing endeavor because of previously invested resources (time, money, effort), even when it would be more rational to cut losses.
• Example:
• Continuing to watch a terrible movie at the theater because you already paid for the ticket.
• Weaknesses:
• Leads to inefficient decision-making.
• Encourages wasteful persistence.
Ethical Theories
Cultural Relativism
• Definition: The belief that moral truth is determined by cultural norms and that there are no universal moral standards.
• View of Moral Truth:
• Morality is relative to a society’s customs and traditions.
• Argument Against:
• If cultural relativism were true, we could not criticize harmful practices in other cultures (e.g., slavery, genocide).
• It implies that moral progress is impossible since it assumes all moral changes are merely shifts, not improvements.
Moral Objectivism
• Definition: The belief that moral truths exist independently of human opinion and cultural norms.
• Contrast with Moral Absolutism:
• Moral objectivism allows for flexibility in moral application, while moral absolutism holds that moral rules apply universally without exception.
• Moral Progress Argument:
• Moral objectivism explains moral progress (e.g., abolition of slavery) because it assumes there are objective moral truths to strive for.
• Argument Against:
• Critics argue that moral objectivism fails to account for cultural diversity in moral beliefs.
The Grounding Problem
• Definition: The philosophical issue of determining the basis or justification for moral truths. Essentially, it asks, “What makes moral claims true?”
Moral Theories
Utilitarianism
• Definition: A moral theory that evaluates actions based on their consequences, specifically aiming to maximize overall happiness or welfare.
• Motive: The right action is the one that produces the greatest happiness for the greatest number.
• Application Example:
• A doctor saves five patients by sacrificing one healthy person for organ donations.
• Difficulty:
• Can justify morally questionable actions (e.g., sacrificing an innocent person for the greater good).
Kantian Ethics
• Definition: A moral theory based on duty and universal moral laws rather than consequences.
• Motive: Actions are morally right if they follow a universalizable principle (categorical imperative).
• Application Example:
• Lying is always wrong, even to protect someone, because if everyone lied, trust in society would collapse.
• Difficulty:
• Can lead to rigid moral obligations that ignore context (e.g., never lying, even in extreme cases).
Political Philosophy and Law
Hobbes: The State of Nature and The Social Contract
• State of Nature:
• A hypothetical condition where there is no government, leading to a “war of all against all.”
• Life is “solitary, poor, nasty, brutish, and short.”
• The Social Contract:
• People give up some freedoms and submit to an authority in exchange for security and order.
Related Concepts:
• Egoism: Hobbes believed humans are inherently selfish.
• Freeloader Problem: A challenge in social contract theory where individuals benefit from the system without contributing.
The Harm Principle
• Definition: John Stuart Mill’s principle that individuals should be free to act however they want unless their actions cause harm to others.
Forms of Paternalism
• Hard Paternalism: Restricting an individual’s liberty for their own good, even if they are fully informed and capable of making their own choices.
• Soft Paternalism: Intervening only when an individual is uninformed or unable to make a rational choice.
• Strong Paternalism: Enforcing measures for people’s well-being even if they disagree.
• Weak Paternalism: Only intervening when someone is acting under misinformation or coercion.
Drug Policy and Legalization
DEA Argument for Prohibition
• Core Idea: Drugs should be illegal because they cause harm to individuals and society (addiction, crime, health issues).
Huemer’s Criticism of DEA Argument
• Key Points:
• Many legal activities (e.g., drinking alcohol, unhealthy eating) also harm individuals, yet they are not prohibited.
• People have the right to control their own bodies.
Huemer’s Positive Argument for Legalization
• Core Idea: Drug use is a personal choice that does not directly harm others, so it should not be criminalized.
• Criticism:
• Some argue that drug use does indirectly harm others through social costs (e.g., medical expenses, accidents).
Masterpiece Cake Shop Case
Arguments for Masterpiece Cake Shop
1. 1st Amendment Free Speech:
• Cake decorating is a form of artistic expression, and forcing someone to create a message they disagree with violates free speech.
2. Free Exercise Clause:
• The owner’s religious beliefs should be protected.
Rebuttal from Colorado Civil Rights Commission (CCRC):
• Anti-discrimination laws protect against refusal of service based on sexual orientation.
Arguments for Colorado Civil Rights Commission
1. Civil Rights Act:
• Businesses open to the public cannot discriminate based on identity.
2. Discrimination:
• Allowing refusals based on religious beliefs could open the door to widespread discrimination.
Rebuttal from Masterpiece:
• The law should not force individuals to express messages that violate their beliefs.
Punishment and Responsibility
Retributivism vs. Utilitarianism in Punishment
• Retributivism: Punishment is justified as a deserved consequence for wrongdoing.
• Utilitarianism: Punishment should be based on future benefits, such as deterrence or rehabilitation.
Moral Responsibility in Law
• Mens Rea (Guilty Mind): A person’s intent or knowledge of wrongdoing.
• Actus Reus (Guilty Act): The physical action of committing a crime.
Levels of Criminal Behavior
1. Intentional – Deliberate wrongdoing.
2. Reckless – Ignoring substantial risk.
3. Negligent – Failing to exercise reasonable care.
4. Strict Liability – Liability without proof of intent (e.g., statutory rape, selling alcohol to minors).
