Definition
Not able to make people believe or trust something.
Example

"When someone is unconvincing, it often means they don’t fully believe what they’re saying themselves."
Explanation
If something is unconvincing, it is not make people believe or agree with it. This can happen because the reasons are weak, there is not enough proof, or it is not explained well. An unconvincing speaker or story might sound unsure, unclear, or unrealistic, making people doubt or reject the idea. It’s the opposite of persuasive and often means the effort to make someone believe didn’t work well.
