Understanding the LSAT Argumentative Writing Task

The LSAT Analytical Writing section, often referred to as the LSAT Essay, tests your ability to analyze an argument and present a persuasive counter-argument or critique. You are given a prompt that presents a specific issue and a proposed course of action or conclusion based on certain evidence. Your task is to write an essay that evaluates this argument, exploring its strengths and weaknesses.

The key is not to agree or disagree with the premise of the argument itself, but rather to assess the reasoning presented. You need to identify assumptions, logical fallacies, and alternative explanations that could weaken or strengthen the given conclusion.

What the Graders Look For

LSAT essay graders are looking for several key components:

  • Clear Thesis: A well-defined position on the argument's validity.
  • Logical Reasoning: Sound arguments, well-supported by evidence and analysis.
  • Identification of Flaws: Ability to pinpoint assumptions, fallacies, and insufficient evidence.
  • Consideration of Alternatives: Exploration of other possible explanations or solutions.
  • Organization and Structure: A coherent essay with a clear introduction, body paragraphs, and conclusion.
  • Clarity and Precision: Effective use of language, grammar, and punctuation.

A Sample LSAT Argumentative Writing Prompt and Example

Let's dive into a practical example.

Prompt:

The following appeared in a memo from the owner of the popular restaurant chain, "Burger Barn":

"In order to increase our profits, Burger Barn should expand its menu to include salads. Our competitor, 'Salad Sensations,' has seen a significant increase in revenue since they introduced a variety of healthy salad options last year. Furthermore, a recent survey of our existing customers indicated that a substantial percentage expressed interest in healthier dining choices. Therefore, by offering salads, Burger Barn will undoubtedly attract new customers and boost overall profitability."

Your Task:

Write an essay in which you evaluate the proposed course of action. Clearly state your own evaluation of the argument and explain your reasoning. In developing your response, consider what additional evidence you would need to evaluate the argument and what specific questions you would ask.

Analyzing the Prompt and Developing a Thesis

Before writing, break down the provided argument:

  • Conclusion: Burger Barn should expand its menu to include salads to increase profits.
  • Evidence:

Competitor "Salad Sensations" increased revenue after adding salads. Burger Barn customer survey showed interest in healthier options.

  • Assumptions:

Salad Sensations' success is solely or primarily due to their salads. Burger Barn's customer base wants salads from Burger Barn. Introducing salads will attract new customers and boost overall profitability, not just cannibalize existing burger sales. Burger Barn can successfully and profitably implement a salad menu.

Based on this analysis, a strong thesis would challenge the direct link between the evidence and the conclusion, highlighting the assumptions.

Example Thesis: While the owner of Burger Barn correctly identifies a potential market trend and customer interest, the memo's conclusion that adding salads will undoubtedly increase profits is not well-supported. The argument relies on questionable assumptions about the competitor's success and Burger Barn's ability to execute such a change effectively, and it fails to consider crucial alternative factors and potential drawbacks.

Crafting the Essay: Section by Section

Introduction

  • Hook: Briefly introduce the memo's proposal and its stated goal.
  • Summary of Argument: Concisely restate the owner's reasoning.
  • Thesis Statement: Clearly state your evaluation of the argument's validity.

Example Introduction:

The owner of Burger Barn proposes expanding the menu to include salads, a strategic move aimed at increasing profits. The memo cites the success of a competitor and internal customer survey data as evidence for this decision. However, a closer examination reveals that the argument's conclusion is premature and potentially flawed, resting on unproven assumptions and overlooking critical factors that could impact the success of such an expansion.

Body Paragraph 1: Challenging the Competitor Analogy

  • Topic Sentence: Focus on the weakness of using Salad Sensations' success as direct proof.
  • Elaboration: Explain why this analogy might be flawed.
  • Questions/Evidence Needed: What specific information would strengthen or weaken this point?

Example Body Paragraph 1:

The memo's assertion that Burger Barn should add salads because "Salad Sensations" has seen increased revenue is a weak point of comparison. The success of Salad Sensations may be attributable to factors entirely unrelated to their salad offerings. For instance, Salad Sensations might have a superior marketing strategy, a more attractive location, a broader appeal to a health-conscious demographic that Burger Barn does not currently target, or perhaps they introduced other successful menu items concurrently. To strengthen this point, we would need to know if Salad Sensations only introduced salads, or if other significant changes occurred simultaneously. We would also need data comparing Burger Barn's potential customer base for salads against Salad Sensations' existing clientele.

Body Paragraph 2: Examining Customer Survey Data

  • Topic Sentence: Address the limitations of the customer survey.
  • Elaboration: Detail the potential issues with survey interpretation.
  • Questions/Evidence Needed: What further information is required?

Example Body Paragraph 2:

Similarly, the customer survey data, while indicating interest, is not conclusive proof of profitability. A "substantial percentage" expressing interest is vague. It is crucial to understand the context of this interest. Did customers express interest in salads from Burger Barn, or just in healthier options generally? Furthermore, expressing interest is not the same as purchasing. Many customers might be interested in a salad option but ultimately continue to purchase burgers, leading to minimal or no increase in overall sales, or even cannibalizing existing burger sales. To properly evaluate this, we need to know the survey's methodology, the exact wording of the question, and whether Burger Barn has data on the likelihood of purchase, not just interest. We also need to know if the survey differentiated between existing Burger Barn customers and potential new customers.

Body Paragraph 3: Considering Operational and Market Challenges

  • Topic Sentence: Introduce the logistical and financial hurdles of adding a new menu category.
  • Elaboration: Discuss potential costs, operational changes, and market saturation.
  • Questions/Evidence Needed: What practical considerations are missing?

Example Body Paragraph 3:

The memo fails to address the practical and financial implications of introducing a salad menu. Developing, sourcing ingredients for, and marketing a new line of salads requires significant investment in kitchen equipment, staff training, and inventory management. Is Burger Barn equipped to handle the preparation of fresh produce without compromising the quality and efficiency of their existing burger operations? Furthermore, the market might already be saturated with salad options, making it difficult for Burger Barn to carve out a profitable niche, especially if their core brand is associated with fast-food burgers. We need to know the projected costs of implementation, the expected profit margins on salads, and an analysis of the competitive landscape for salads in Burger Barn's target markets.

Body Paragraph 4: Alternative Strategies and Potential Downsides

  • Topic Sentence: Suggest alternative approaches or highlight overlooked risks.
  • Elaboration: Propose other ways to meet the goal or detail negative outcomes.
  • Questions/Evidence Needed: What other options exist?

Example Body Paragraph 4:

Instead of a complete menu overhaul, Burger Barn could explore less drastic measures. Perhaps introducing a single, signature salad as a limited-time offer could gauge customer demand more effectively and with lower risk. Alternatively, if the goal is to attract a health-conscious demographic, Burger Barn could focus on offering healthier versions of their existing products, such as grilled chicken options or whole-wheat buns, which align more closely with their brand identity. The memo also doesn't consider the potential negative impact on Burger Barn's brand image. If the salads are perceived as a departure from Burger Barn's core identity, it could alienate loyal customers who associate the brand with classic burgers.

Conclusion

  • Restate Thesis (in different words): Reiterate your main point about the argument's weakness.
  • Summarize Key Criticisms: Briefly touch upon the main flaws you identified.
  • Final Thought/Recommendation: Offer a concluding statement about the need for more data and careful planning.

Example Conclusion:

In conclusion, while the ambition to increase profits by catering to evolving customer preferences is commendable, the memo's argument for adding salads to the Burger Barn menu is inadequately supported. The reliance on a superficial competitor comparison, the ambiguous customer survey data, and the complete omission of operational and financial considerations render the conclusion that profits will undoubtedly rise unconvincing. Before making such a significant strategic shift, Burger Barn requires more robust data, a thorough feasibility study, and a careful consideration of alternative strategies to ensure a truly beneficial outcome.
