 Critical thinking (or, even more so, creative thinking) skills are not easily assessed using standardized tests which are designed for large scale use, and typically rely on multiple choice question and answers (see Sobocan 2021). In real life contexts, what counts as good arguing (and thinking) is open ended and unpredictable, dialectical, and influenced by pragmatic and contextual considerations which are difficult to incorporate within standard tests. The California Critical Thinking Test reflects the view of critical thinking elaborated in “The Delphi Report,” commissioned by the American Philosophical Association in 1987, a report that focuses on a narrow range of critical thinking skills which tends to oversimplify the competencies required for good informal argument.
