Final answer:
Dogmatism is a cognitive style marked by closed-mindedness and inflexibility; the claim that it is characterized by such traits is true. It signifies a staunch adherence to beliefs, often hindering critical thinking and epistemic humility.
Step-by-step explanation:
Dogmatism refers to a cognitive style that is characterized by closed-mindedness and inflexibility. This claim is true. It typically signifies an unwavering adherence to a set of beliefs or principles regardless of new evidence.
The question touches on aspects relevant to cognitive styles and their influence on belief systems, which is a topic of interest in psychology, a sub-discipline within Social Studies.
Dogmatism can make critical thinking difficult because it can entail a rejection of new ideas or evidence that contradicts established beliefs. It is important to instead foster epistemic humility, which acknowledges the limits of one's own knowledge.
Philosophical views, including the Logical Positivists' approach to religious language, can be seen as a form of dogmatism if they dismiss other perspectives outright without considering their possible value or truth.
