Weakening an Argument

To weaken an argument, you need to find a flaw or weakness in the reasoning. This could involve showing that the premises don't support the conclusion, that there are alternative explanations, or that the argument relies on faulty assumptions.

Study Notes

LSAT Stimuli Categories

  • LSAT stimuli fall into two categories: arguments and sets of facts.

Primary Objective #1

  • Determining if the provided stimulus is an argument or a set of facts.
  • Determining if a conclusion is present.

Premise Indicators

  • Because
  • Since
  • For example
  • For the reason that
  • In that
  • Given that
  • As indicated by
  • Due to
  • Owing to
  • This is seen from
  • We know this by/because

Conclusion Indicators

  • Thus
  • Therefore
  • Hence
  • Consequently
  • As a result
  • So
  • Accordingly
  • Clearly
  • Must be that
  • Shows that
  • Concludes
  • Follows that
  • For this reason

Note on Order

  • Conclusions and premises can be in any order. The order of presentation does not affect the logical structure of an argument.

Primary Objective #2

  • Identify the conclusion of an argument.
  • Identify each fact and examine it closely if the stimulus contains a set of facts.

Additional Premises

  • Authors sometimes add additional premises for good measure.
  • Additional premises aren't always essential to the conclusion.

Counter-Premise Indicators

  • But
  • Yet
  • However
  • On the other hand
  • Admittedly
  • Although
  • In contrast
  • Even though
  • Still
  • Whereas
  • After all
  • In spite of
  • Despite

Additional Tips and Techniques

  • Turn an argument into a conversation.
  • Take statements and order them so one statement is a conclusion, then add indicators.
  • Repeat this until the logical structure makes sense.

Primary Objective #3

  • Determine if an argument is strong or weak.
  • Determine if premises justify the conclusions.
  • Distinguish between inferences and assumptions.

Inference

  • Inferences follow from an argument. (Occur after the argument).

Assumption

  • Assumptions are taken for granted in an argument. (Occur before the argument).

Identifying The Question Stem

  • Carefully read and identify the question stem.
  • Do not assume words automatically associate with certain question types.

Thirteen Logical Question Stems

  • Must be true/most supported
  • Main point
  • Point of issue
  • Assumption
  • Justify the conclusion
  • Strengthen the support
  • Resolve the paradox
  • Weaken
  • Method of reasoning
  • How in the reasoning
  • Parallel reasoning
  • Evaluate the argument
  • Cannot be true

Probability Indicators

  • Must
  • Will
  • Always
  • Not always
  • Probably
  • Likely
  • Should
  • Would
  • Could
  • Not necessarily
  • Rarely
  • Never

Primary Objective #5

  • Carefully read and identify the question stem.
  • Do not assume certain words automatically associate with certain question types.

Primary Objective #6

  • Prephrase your answer to the stem after reading the question.

Primary Objective #7

  • Always read all five answer choices.

Primary Objective #8

  • Separate answers into contenders and losers.

Primary Objective #9

  • If all of the options appear to be wrong, return to the stimuli and re-evaluate.

Chapter 4: Must Be True

  • The correct answers must be proven by facts in the stimulus.
  • Incorrect answers include exaggerations, new information, opposite answers, and reversed answers.

Chapter 5: Main Point Questions

  • Incorrect answer types include statements that are true but not the main point, and premises of the argument.

Chapter 6: Conditional Reasonings

  • Contrapositive negates both parts and reverses the arrow.
  • Sufficient indicators include when, whenever, if, every, all, etc.
  • Necessary indicators include then, only, if, when, whenever, etc.

Chapter 7: Weakening Questions

  • Correct answers weaken the conclusion, not necessarily the premise (though sometimes a premise can be weakened if it's a subconclusion).
  • Flaws in arguments include incomplete information, improper correlation, and out of scope answers.

Chapter 8: Cause and Effect Reasoning Questions

  • The cause must make the effect happen.

Chapter 9: Strengthen and Justify Conclusion Questions

  • Understand the argument's structure and focus on the conclusion.
  • The stimulus might be suspect.

Chapter 10: Resolved Paradox

  • The answer will prove how both elements can happen, not disprove one.

Chapter 11: Method of Reasoning

  • If an answer describes an event that didn't happen, it will be incorrect.

Chapter 13: Flaw in Reasoning

  • Common flaws include uncertain use of words or terms, source arguments, circular reasoning, and mistaken causal relationships.

Chapter 15: Numbers and Percentages

  • Increasing percentages equal increasing numbers, and vice versa.
  • Decreasing percentages equal decreasing numbers, and vice versa.

Chapter 16: Evaluate the Argument

  • Use the variance test to use polar opposite answers and see if one proves or disproves the conclusion.

Chapter 17: Cannot Be True

  • Accept the stimulus.
  • If an answer contains new or combined information from the stimulus, it is wrong.

Chapter 18: Point of Issue

  • Identify facts to fix (ethical disagreements), facts agreed upon, and unknown speakers' views.

Chapter 19: Principles Questions

  • Apply the principle in a broad context.
