Identify the Flaw

Identify the Flaw questions are very common on the LSAT, and they can be some of the most difficult. However, there are some strategies we can use to create an efficient, accurate, and repeatable process for finding the right answers.

Repeated Flaws

First of all, there are a limited number of logical flaws that the test writers include on the LSAT. What this means is that as you practice you should be making note of every flaw you come across and noticing when they repeat. A flaw that may be difficult for you to spot today could become very easy for you to spot with a few months of practice, as you will see it used repeatedly across many questions.

Vague or Confusing Answer Choices

An aspect of Flaw questions that can make them very difficult is the sometimes vague and confusing wording of the answer choices. There's no "hack" for this issue, sometimes the answer choices are genuinely difficult to understand. However, again, with practice you can start to see patterns and understand what certain confusing phrases are referencing.

For example, an answer choice may say "treats an action that is sufficient for an outcome to follow as though it were also necessary for that outcome." In real life no one talks like this, but experienced LSAT students can read this and just understand that the answer choice is referring to a sufficient/necessary swap.
