Why do authors emphasize evidence that they feel is more convincing?

to write about different topics
to discourage others from forming an opinion
to ignore opposing arguments
to strengthen their own argument

The main reason authors emphasize evidence they find more convincing is to strengthen their own argument. By highlighting and providing strong evidence that supports their claims, authors aim to make their arguments more persuasive and credible. This helps them to persuade their readers or audience to take their stance or point of view on a specific topic.
