Inference - Logical Reasoning

  1. Define 'false dilemma' fallacy.
    Presenting two options as the only possibilities. Ignores other possible alternatives or middle ground.
  2. What is the definition of a valid argument?
    If premises are true, the conclusion must be true. Defines the logical requirement for argument validity.
  3. What defines a hasty generalization?
    Drawing a conclusion from insufficient evidence. Reaches broad conclusions from limited sample size.
  4. 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.
  5. Identify the principle: 'If A, then B; not B; therefore, not A.'
    Modus tollens. Uses contrapositive reasoning to deny the antecedent.
  6. 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.
  7. What is the role of a premise in an argument?
    To provide support for the conclusion. Premises justify believing the conclusion is true.
  8. 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.
  9. Define 'begging the question.'
    Assuming the conclusion within the premises. Circular reasoning that doesn't provide independent support.
  10. What defines the bandwagon fallacy?
    Assuming something is true because many believe it. Appeals to popularity rather than logical merit.
  11. 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.
  12. Define 'red herring' fallacy.
    Distracting from the main issue with irrelevant information. Diverts attention away from the real argument.
  13. What describes an argument where the conclusion follows necessarily from the premises?
    Valid argument. The conclusion is logically entailed by the premises.
  14. Define deductive reasoning.
    Reasoning from general premises to a specific conclusion. Moves from universal principles to particular cases.
  15. Identify the error: 'If A, then B. Not A, therefore, not B.'
    Denying the antecedent. Incorrectly assumes absence of antecedent prevents consequent.
  16. Identify the flaw: 'If A, then B. B, therefore A.'
    Affirming the consequent. Incorrectly assumes the conditional works both directions.
  17. Which term describes the relationship between premises and conclusion?
    Logical validity. Describes how well premises support the conclusion.
  18. Which logical principle states 'If A, then B; A; therefore, B'?
    Modus ponens. The basic form of affirming the antecedent.
  19. What is the role of evidence in an argument?
    To support premises and strengthen the argument. Provides factual support to make arguments more convincing.
  20. Identify the premise: 'If it rains, the ground is wet. It is raining.'
    It is raining. States the condition that triggers the conditional.
  21. 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.
  22. Which term refers to the logical form of an argument?
    Argument structure. The logical pattern underlying the specific content.
  23. What is a sufficient condition?
    A condition that, if true, guarantees the statement is true. Alone guarantees the truth of the statement.
  24. What describes a sound argument?
    Valid argument with true premises. Combines validity with factually correct premises.
  25. What is the counterexample method?
    Using an example to show an argument is invalid. Shows invalidity by finding true premises, false conclusion.
  26. Choose the term: A statement that supports a conclusion.
    Premise. Premises provide evidence or support for conclusions.
  27. 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.
  28. What is an inference in logical reasoning?
    A conclusion drawn from premises or evidence. This defines the basic concept of drawing logical conclusions.
  29. 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.
  30. What is the main goal of logical reasoning?
    To evaluate arguments for validity and soundness. Tests whether conclusions follow logically from premises.
  31. 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.
  32. What error occurs when causation is mistaken for correlation?
    Post hoc fallacy. Confuses temporal sequence with causal relationship.
  33. What does it mean if an argument is 'cogent'?
    Strong argument with true premises. Strong inductive argument with true premises.
  34. Identify the reasoning type: Generalizing from specific instances.
    Inductive reasoning. Builds general rules from specific observations or examples.
  35. What is the straw man fallacy?
    Misrepresenting an argument to refute it easily. Creates a weaker version to attack more easily.
  36. What term describes an argument with true premises but a false conclusion?
    Invalid argument. Valid form cannot have true premises with false conclusion.
  37. What is the difference between inductive and deductive reasoning?
    Inductive infers generalizations; deductive derives specifics. Inductive creates patterns; deductive applies established rules.
  38. What is the purpose of a conditional statement?
    To express a dependent relationship between propositions. Shows logical dependency between two propositions.
  39. What is an equivocation fallacy?
    Using a word with multiple meanings misleadingly. Exploits ambiguity to make invalid connections.
  40. What is a counterargument?
    An argument that opposes or refutes another argument. Challenges or disputes the original argument's claims.
  41. What is the principle of charity in argument analysis?
    Interpreting arguments in their strongest form. Avoids attacking weak versions of arguments unfairly.
  42. Identify the logical principle: 'Either A or B; not A; therefore, B.'
    Disjunctive syllogism. Eliminates one disjunct to affirm the other.
  43. 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.
  44. What is an ad hominem fallacy?
    Attacking the person instead of the argument. Targets the arguer rather than addressing their reasoning.
