What refers to the skills used to solve problems and make decisions effectively?

The most relevant term that describes the skills used to solve problems and make decisions effectively is critical thinking. Critical thinking involves analytical skills, evaluation of information, and the ability to reason logically, all of which are fundamental components in approaching problem-solving and decision-making effectively.

Planning, while important, refers more to the process of setting goals and outlining steps to achieve them rather than specifically addressing the analytical aspect of tackling problems or making decisions. Evaluative thinking focuses on assessing and appraising information but does not encompass the broader cognitive processes involved in critical thinking.

Problem-solving skills are indeed related to making decisions and resolving issues, but they tend to focus narrowly on the execution of finding solutions, rather than the comprehensive analytical framework that critical thinking embodies. Understanding the nuances between these terms helps clarify why critical thinking stands out as the best descriptor for the set of skills mentioned in the question.
