Conditional reasoning appears throughout the LSAT, in the arguments presented within the Logical Reasoning sections of the test, in the grouping games that are featured in every Logic Games section, and even (to a lesser extent) in the Reading Comprehension section of the test. This type of logic classifies conditions as Sufficient or Necessary, depending on whether they are sufficient to glean further information, or necessary for something else to be true or to occur (for an expansive discussion of conditional reasoning as it applies to the LSAT, check out the new 2016 Logical Reasoning Bible). This area represents an important component of legal reasoning, of course, but more importantly from test makers’ perspective, conditional reasoning has proven to be a reliable source of confusion for test-takers.
