DON'T CALL IT A COMEBACK

Grey Day has come and gone. LSAT scores are out. Congratulations to all who wrote the June exam! For everyone preparing for an upcoming LSAT or interested in the breakdown of the June LSAT's composition, we've analyzed the test in detail and would like to share our insights with you. Today we'll get our recap kicked off with Logical Reasoning. Subscribe to this blog to get notified of our upcoming posts, including complete video explanations of the games and an in-depth recap of Reading Comprehension.

Ready for the "TL;DR" version of the June 2017 LR sections? Here are the highlights:

  • Heavy use of conditional reasoning and formal logical structure on a broad cross-section of questions.
  • Continued importance of causal reasoning, but principally on a restricted set of question tasks.
  • Compared to the December 2016 test and statistical averages, a higher ratio of Weaken questions to Strengthen questions.
  • Use of a couple minor informal fallacies.

Read below for a detailed discussion of the above points and statistics about the questions.


THE BOX SCORE

QUESTION TYPE

1st SECTION

2nd SECTION

SUBTYPES

NOTES

Must Be True 6 4 1 principle question  
Main Point 1 2    
Point at Issue/Agree 1 1 1 agree, 1 disagree  
Assumption 3 1    
Justify  2 2    
Strengthen 2 1 1 principle 2 causal
Resolve the Paradox 2 2   All causal
Weaken 2 2   3 causal
Method of Reasoning 1 3    
Flaw 3 5   1 causal
Parallel  2 2 2 Reasoning, 2 Flaw  
Evaluate 1 0    
Cannot Be True 0 0    

Overall there were twenty-six questions in the first LR section and twenty-five in the second. As usual, there were more "Help" task questions than "Hurt" task (Weaken) questions, but there was one more Weaken question than there were pure Strengthen questions. 

Causal reasoning remains of paramount importance, but note that causal flaws and tasks were restricted principally to Weaken, Strengthen, and Resolve the Paradox questions. One flaw question tested causal reasoning. In general, causal reasoning was more significant on less challenging questions on these LR sections.

The following table is an overview of some of the principles of argumentation and fallacies that appeared on this test.

Reasoning Principle/Flaw

Number of Occurrences

Notes

Causal 11  
Argument from Analogy 3  
Conditional Reasoning 13 Not including deductive reasoning on Must be True problems
Cherry Picking 1  
Fallacy of Division 1  
Absence of Evidence 3 One Argument from Incredulity
Fallacy of Composition 2 One is actually an assumption that "emergence" (composition) does not occur while it actually could!
Error in the Use of Evidence 1  
Dad Jokes 1  

Note that a strong grasp both of conditional reasoning and formal logical fallacies was essential to success on this administration of the LSAT. Overall, our impression of these Logical Reasoning questions is that they were par for the course. Along with the (relatively) unremarkable Analytical Reasoning section, these LR sections account in part for the tight -9 curve on this LSAT.

There was a challenging parallel question at the end of the second logical reasoning section, but as with every other question, there was no situation presented that was so confounding that a correct use of your LR process couldn't overcome the challenge. For instance, this Parallel question could be reduced to a modus tollens single conditional/contrapositive structure and compared quickly to the answer choices. 

Grumpy Cat CC BY 2.0 Jennifer MorrowYou might be wondering about the "dad joke." LSAT humor is a subject unto itself and could be discussed at length, but every once in a while you might come across some (very dry) wit in a question. On this test it happened in a "kids these days!" scenario on a Must Be True question. At least we have some evidence that the LSAC does not take itself completely seriously!


THE BIG PICTURE

If you are preparing for the September or December LSAT, what should you observe from the June 2017 Logical Reasoning sections?

  • The LSAC did not reinvent the wheel here. Few surprises means proceed confidently with existing, tried-and-true approaches to LR problems.
  • Continue to master the fundamentals. Even experienced instructors and masters of the LSAT can benefit from revisiting the basics. Ensure that you have a strong grasp of inferences, deduction, conditional reasoning, and common flaws, especially causality.
  • Do not overlook minor flaws and informal fallacies. Your ability quickly to describe some of these less-common situations will strengthen your ability to prephrase/predict the answer and maintain your momentum throughout the test.
  • Don't expect any administration to be a carbon-copy of any previous administration. Expect variations from test to test, but know that your strong skill set will translate to an excellent performance no matter what appears on your test.
