Some people don't like giving their opinions because they're afraid of being judged. They worry that others might criticize or make fun of them. Also, there's a fear of saying something that might offend someone else. This fear of being misunderstood or causing conflict makes them prefer to stay quiet rather than speak up.

People sometimes don't share their opinions because they lack confidence. They might feel unsure about their knowledge on a topic and think their opinion isn't important. Some people are also intimidated by those who are more outspoken. They prefer to listen and learn from others instead of speaking up themselves.

Some people might not like giving their opinions due to cultural or personal reasons. In some cultures, open expression is discouraged, and people are raised in environments where opinions aren't valued. Additionally, introverted individuals might prefer to keep their thoughts private. They believe in maintaining harmony and avoiding dissent, so they choose not to express their opinions openly.
