This document outlines the steps for developing critical thinking skills: Step 1 is to identify an argument by establishing a line of thinking with reasons presented to support a conclusion. Effective arguments have two relevant reasons that logically lead to the conclusion. Step 2 is to evaluate the evidence used to support the argument. This involves considering whether the evidence is relevant, recent, relies on assumptions, or shows potential bias. The strength of an argument depends on unbiased, sufficient evidence that is directly relevant to supporting the conclusion.
