The degree of openness of thought cannot be judged simply based on a person's religious beliefs. On the one hand, religious belief is a complex personal choice and spiritual sustenance. There are rich doctrinal interpretations and diverse practice methods within different religions, and the understanding and practice of believers vary widely. Some devout religious believers uphold an open, tolerant, and rational attitude towards the relationship between religion and life, actively participate in social affairs, respect different views and cultures, and are not conservative and narrow-minded. On the other hand, the degree of openness of thought is comprehensively affected by a variety of factors, including personal educational background, life experience, social environment, and personal personality traits. A person without religious beliefs may be more conservative and closed in thought, while a person with religious beliefs may also have a broad vision, innovative thinking, and acceptance of diversity. It is inaccurate and one-sided to simply equate religious beliefs with the degree of openness of thought. It is necessary to understand and understand a person comprehensively and comprehensively, rather than making stereotypical judgments based on beliefs.
