Inference - Logical Reasoning
- Define 'false dilemma' fallacy.
- Presenting two options as the only possibilities. Ignores other possible alternatives or middle ground.
- What is the definition of a valid argument?
- If premises are true, the conclusion must be true. Defines the logical requirement for argument validity.
- What defines a hasty generalization?
- Drawing a conclusion from insufficient evidence. Reaches broad conclusions from limited sample size.
- Identify the principle: 'If A leads to B and B leads to C, then A leads to C.'
- Transitive property. Links relationships through intermediate connections.
- Identify the principle: 'If A, then B; not B; therefore, not A.'
- Modus tollens. Uses contrapositive reasoning to deny the antecedent.
- What is the definition of a false analogy?
- Comparing two unlike things as if they are similar. Treats dissimilar situations as if they're equivalent.
- What is the role of a premise in an argument?
- To provide support for the conclusion. Premises justify believing the conclusion is true.
- What is a slippery slope fallacy?
- Arguing that a small step leads to a chain of events. Claims one action inevitably leads to extreme consequences.
- Define 'begging the question.'
- Assuming the conclusion within the premises. Circular reasoning that doesn't provide independent support.
- What defines the bandwagon fallacy?
- Assuming something is true because many believe it. Appeals to popularity rather than logical merit.
- Identify the error: 'All cats are mammals. Some mammals are dogs. Therefore, some cats are dogs.'
- Invalid argument. The middle term doesn't properly connect the premises.
- Define 'red herring' fallacy.
- Distracting from the main issue with irrelevant information. Diverts attention away from the real argument.
- What describes an argument where the conclusion follows necessarily from the premises?
- Valid argument. The conclusion is logically entailed by the premises.
- Define deductive reasoning.
- Reasoning from general premises to a specific conclusion. Moves from universal principles to particular cases.
- Identify the error: 'If A, then B. Not A, therefore, not B.'
- Denying the antecedent. Incorrectly assumes absence of antecedent prevents consequent.
- Identify the flaw: 'If A, then B. B, therefore A.'
- Affirming the consequent. Incorrectly assumes the conditional works both directions.
- Which term describes the relationship between premises and conclusion?
- Logical validity. Describes how well premises support the conclusion.
- Which logical principle states 'If A, then B; A; therefore, B'?
- Modus ponens. The basic form of affirming the antecedent.
- What is the role of evidence in an argument?
- To support premises and strengthen the argument. Provides factual support to make arguments more convincing.
- Identify the premise: 'If it rains, the ground is wet. It is raining.'
- It is raining. States the condition that triggers the conditional.
- Identify the conclusion: 'All men are mortal. Socrates is a man. Therefore, Socrates is mortal.'
- Socrates is mortal. The conclusion follows 'Therefore' in this syllogism.
- Which term refers to the logical form of an argument?
- Argument structure. The logical pattern underlying the specific content.
- What is a sufficient condition?
- A condition that, if true, guarantees the statement is true. Alone guarantees the truth of the statement.
- What describes a sound argument?
- Valid argument with true premises. Combines validity with factually correct premises.
- What is the counterexample method?
- Using an example to show an argument is invalid. Shows invalidity by finding true premises, false conclusion.
- Choose the term: A statement that supports a conclusion.
- Premise. Premises provide evidence or support for conclusions.
- What is a necessary condition?
- A condition that must be true for a statement to be true. Required for the statement's truth; cannot be absent.
- What is an inference in logical reasoning?
- A conclusion drawn from premises or evidence. This defines the basic concept of drawing logical conclusions.
- Find the logical fallacy: 'If it rains, the ground is wet. The ground is wet, so it rained.'
- Affirming the consequent. Assumes the antecedent from the consequent being true.
- What is the main goal of logical reasoning?
- To evaluate arguments for validity and soundness. Tests whether conclusions follow logically from premises.
- Identify the flaw: 'If A, then B. If B, then C. Therefore, if A, then C.'
- No flaw; valid argument. This demonstrates valid hypothetical syllogism reasoning.
- What error occurs when causation is mistaken for correlation?
- Post hoc fallacy. Confuses temporal sequence with causal relationship.
- What does it mean if an argument is 'cogent'?
- Strong argument with true premises. Strong inductive argument with true premises.
- Identify the reasoning type: Generalizing from specific instances.
- Inductive reasoning. Builds general rules from specific observations or examples.
- What is the straw man fallacy?
- Misrepresenting an argument to refute it easily. Creates a weaker version to attack more easily.
- What term describes an argument with true premises but a false conclusion?
- Invalid argument. Valid form cannot have true premises with false conclusion.
- What is the difference between inductive and deductive reasoning?
- Inductive infers generalizations; deductive derives specifics. Inductive creates patterns; deductive applies established rules.
- What is the purpose of a conditional statement?
- To express a dependent relationship between propositions. Shows logical dependency between two propositions.
- What is an equivocation fallacy?
- Using a word with multiple meanings misleadingly. Exploits ambiguity to make invalid connections.
- What is a counterargument?
- An argument that opposes or refutes another argument. Challenges or disputes the original argument's claims.
- What is the principle of charity in argument analysis?
- Interpreting arguments in their strongest form. Avoids attacking weak versions of arguments unfairly.
- Identify the logical principle: 'Either A or B; not A; therefore, B.'
- Disjunctive syllogism. Eliminates one disjunct to affirm the other.
- Identify the premise: 'If it rains, then the picnic is canceled. It is raining.'
- It is raining. The premise provides the condition for the conditional.
- What is an ad hominem fallacy?
- Attacking the person instead of the argument. Targets the arguer rather than addressing their reasoning.
