Critical thinking requires a variety of tools

From Public Books: "Critical thinking is an 'intellectually disciplined process' — overarching (or sidestepping) all disciplines per se. It involves a chain of 'and/or' activities that can happen in so many contexts … it is a sort of mental Swiss Army Knife, able to unfold a range of analytic tools depending on the circumstances. … In other words, just because teaching is conducted under the explicit rubric of critical thinking, it cannot be taken as a given that expected actions will result. Rather, students' actions in the world will tell you if critical thinking has taken place."
