Critical thinking is a form of metacognition involving the analysis of one’s own process of reasoning, assumctions, and bias so as to identify flaws and improve one’s thinking by applying critical standards. As such critical thinking is the process of analyzing and assessing thinking with a view to improving it; it is often referred to simply as “thinking about thinking.” Likewise, critical thinking involves the¬†capacity to distinguish between effective and ineffective processes of inference, valid and invalid data sources and requires the formation of beliefs based upon sound reasoning. The literature on critical thinking has roots in two primary academic disciplines: philosophy and psychology and is increasingly recognized¬†as an important 21st-century skill by educators.
