Expert writing Tips
Best practice
Use "it's not clear" to introduce a point of uncertainty before presenting various possible explanations or outcomes.
Common error
Avoid using "it's not clear" excessively, as it can lead to a passive and vague writing style. Instead, try to identify who lacks clarity or what specifically is unclear, and rephrase for a more direct statement. For instance, instead of saying "It's not clear what caused the error", try "The cause of the error remains unknown" or "Researchers have not yet determined the cause of the error."

In order to prevent overuse, it is advisable to explore alternatives such as "it remains uncertain" or "the situation is ambiguous" for a more nuanced writing style. Due to the lack of any specific examples extracted from the search, it's crucial to use the phrase deliberately and back it up with evidence and context.
