Dogmatic means insisting that your beliefs are absolutely right and refusing to consider other viewpoints or evidence. A dogmatic person states their opinions as if they were undeniable facts and won't listen when others disagree or offer different perspectives.

Imagine a student who insists there's only one correct way to solve a math problem, even after the teacher shows three different valid approaches. Or picture someone who declares that chocolate ice cream is objectively the best flavor and won't accept that others might genuinely prefer vanilla. That's dogmatic thinking: treating personal opinions or beliefs as unchangeable truths.

The word often describes people who hold their ideas so rigidly that they can't learn new things or adapt when circumstances change. A dogmatic coach might refuse to try new training methods even when the old ones aren't working. A dogmatic reader might insist that books from one particular time period are the only ones worth reading.

Scientists try hard not to be dogmatic. Good science means following evidence wherever it leads, even when it contradicts your original hypothesis. Being open to new information and willing to change your mind when presented with better evidence is the opposite of dogmatism. You can have strong convictions without being dogmatic. The difference is whether you remain curious and open to discovering you might be wrong.
