Why are people dogmatic?

Answer 1

They're more concerned with laws and rules than principles. Jesus chastised the Pharisees for such thinking; They were insistent on keeping up appearances (Ecclesiastes 7:16; Matthew 23:23-27) instead of focusing on the "spirit of the law" a.k.a. the principles behind it. (Matthew 22:36-40)

(New World Translation of the Holy Scriptures)

Answer 2

People are often dogmatic due to a combination of psychological, social, and emotional factors. Strong beliefs can provide a sense of security and identity, making it easier to navigate complex worldviews. Additionally, cognitive biases, such as confirmation bias, reinforce existing beliefs by leading individuals to favor information that supports their views while dismissing contradictory evidence. Social influences, including group dynamics and cultural norms, can also encourage dogmatism by creating environments where dissenting opinions are discouraged.
