A Core Concept of LR: The Controlled Experiment

Lucas Carter

In Logical Reasoning sections, LSAC loves to test us on how we interpret studies. For example, a study is described, a conclusion is drawn, and it becomes our job to evaluate how well the study supports the conclusion. These questions are common and come in the form of: flaw, strengthening, weakening, necessary assumption, sufficient assumption, and if they are feeling really ambitious: resolve reconcile questions.

These questions mostly turn on how well the study is controlled. This video below takes you through what it means for an experiment to be controlled and why it is fundamental to "good" science.

Next time you do an LR section, notice how much the controlled experiment comes up, and how you must understand what makes it better or worse!
