LSAT Logical Reasoning: The Argument-Type Playbook
All Episodes

Stop the LSAT Spreadsheet Trap

The hosts unpack why overanalyzing LSAT question subtypes can become a form of data sickness, and explain how to use performance tracking without getting lost in spreadsheets. They also share a practical review method: hide the answer choices, reconstruct the argument in plain English, and identify the logical gap before checking the key.


Chapter 1

The Data Sickness and the Subtype Worksheet Trap

Adrian Calloway

So, I- I- I was looking at this new tool LSAC put out, Nora. It's called the, uh, Strategy Booster, which they're hosting on LawHub now that the old Khan Academy LSAT materials have retired and migrated over. And, look, it's a- it's a free, self-paced course to, you know, optimize study strategies. But there's this one specific thing in Module 5. It's a, uh, "Subtype Scoring Worksheet" designed to help you track your performance by question subtype across multiple practice tests.

Nora Ashford

Oh, god. A spreadsheet. Adrian, you are speaking directly to my dark, obsessive past. When I was self-studying, I had a forty-column Google Sheet. I had columns for "conditional necessary assumption," "causal weaken," "flaw with-with conditional elements." I spent hours color-coding it. I thought I was being so- so scientific.

Adrian Calloway

Right, and that is exactly the trap. I call it "data sickness." Students spend, what, three hours cataloging and- and color-coding a practice test, and maybe thirty minutes actually analyzing why they got the questions wrong. It's admin work masquerading as actual studying. You feel like you're making progress because the dashboard looks beautiful.

Nora Ashford

Yes! It's a massive dopamine hit. You're like, "Look at me, I'm- I'm diagnosing my systemic weaknesses." But- but wait, the worksheet is literally designed to track performance by question subtype. Are you saying LSAC is giving bad advice here?

Adrian Calloway

Not bad advice, just... easily misused. Think of it like a deposition. If you're a litigator, and you're questioning a witness who is dodging your question, you don't stop the deposition to- to consult a chart and say, "Ah, yes, that's a classic ad hominem subtype 4B." No! You don't care about the academic label. You just spot the gap. You see that their evidence doesn't actually support their claim, and you press them on it. The LSAT is the same. The test rewards finding the logical skeleton, not decorating a dashboard with micro-classifications.

Nora Ashford

Okay, so- so instead of agonizing over whether a question is a "strengthen-with-sufficient-premise" or whatever, I just need to ask, "Why does this argument fail to prove its conclusion?"

Adrian Calloway

Exactly. If you can't find the premise and the conclusion, and the specific gap between them, all the spreadsheet columns in the world won't save you on test day.

Chapter 2

The No-Look Method for True Prep Boost

Nora Ashford

Alright, so if we're throwing away the forty-column spreadsheet, how do we actually fix the mistakes? Because when I was reviewing on LawHub, I'd miss a question, look at the correct answer, and go, "Oh, obviously. Yeah, B makes total sense. I see it now." And then I'd move on. But then, surprise surprise, I'd make the exact same mistake on the next PT.

Adrian Calloway

Right, because that "oh, that makes sense" reaction is a cognitive illusion. It's passive recognition. You're just validating the test-makers' work. You're- you're essentially saying, "Yes, I agree that the correct answer is indeed correct." But you didn't do the heavy lifting of finding it yourself. You didn't build any new neural pathways.

Nora Ashford

So how do we force those pathways to actually, you know, build?

Adrian Calloway

You use what I call the "No-Look" reconstruction. When you review a missed question, you cover the answer choices entirely. Do not look at them. You go back to the stimulus, and you write down, in plain English—no formal logic symbols, just normal speech—what the premise is, what the conclusion is, and then you declare the logical gap yourself. You write down: "This argument assumes that just because X happened, Y must cause it." Only when you have written that down do you let yourself look at the choices to find the one that matches your prediction.

Nora Ashford

I actually did a version of this! Once I realized the spreadsheets weren't working, I started explaining the logical gaps out loud to my dog, Buster. If I couldn't explain to a golden retriever why the author was being an idiot, I didn't actually understand the flaw. It- it felt ridiculous, but my score shot up like five points in three weeks.

Adrian Calloway

Buster is the ultimate LSAT tutor. But seriously, that is the work. Now, I will concede one thing on the Strategy Booster. If you use their data to spot broad, systemic collapses—like, "Hey, every time conditional logic shows up, I panic"—that's useful. You can use LawHub's free drills to target that. But don't let it paralyze you. When the clock is ticking down in a Prometric testing room, you cannot be running a taxonomic classification system in your head. You just need to find the gap.

Nora Ashford

Right. Don't classify the beast. Just, uh, shoot it. Or, you know, point out its logical flaws. Alright, I'm going to go pet Buster. Good chatting, Adrian.

Adrian Calloway

Talk soon, Nora.
