Critical thinking means being able to evaluate evidence, to tell fact from opinion, to see holes in an argument, to tell whether cause and effect has been established and to spot illogic. “Most research shows you can teach these skills,” notes cognitive psychologist D Alan Bensley of Frostburg State University, Maryland. “But critical-thinking skills are different from critical-thinking dispositions, or a willingness to deploy those skills.”
In other words, critical-thinking skills are necessary for engaging in critical thinking, but they are not sufficient. You also have to want to think critically. If you have good critical-thinking skills but for some reason are not motivated to deploy them, you will reach conclusions and make decisions no more rationally than someone without those skills.
