Expert writing Tips

Best practice

When using "lacked conviction", ensure the subject's lack of belief is directly relevant to the context. For instance, a politician's speech "lacked conviction" if they failed to persuade the audience.

Common error

Avoid using "lacked conviction" when the issue isn't the subject's belief, but external factors. For example, instead of saying "The evidence lacked conviction", clarify that "The evidence was unconvincing" or "The case was not convincingly proven".
