What term describes the ability to reflect upon the adequacy of one's thoughts and actions?

The correct term for the ability to reflect upon the adequacy of one's thoughts and actions is self-reflectiveness. This concept emphasizes the capacity to consciously examine and assess one's own mental processes and behaviors. Self-reflectiveness involves a critical evaluation of one's beliefs, feelings, and motives and encourages a deeper understanding of one's personal experiences and decisions.

Self-awareness, while related, specifically refers to the recognition of oneself as an individual, including understanding one's emotions and how they affect behavior. Self-evaluation focuses more narrowly on judging or measuring one’s performance or worth against certain criteria, often with an outcome-oriented perspective. Self-analysis suggests a more systematic examination of oneself, often implying the use of psychological methods, but it may lack the broader context of reflective thinking that self-reflectiveness encompasses.

Therefore, self-reflectiveness best captures the broader scope of critically assessing the adequacy of one's own thoughts and actions.
