Expert writing Tips

Best practice

Use "is not believed to be" when you want to express a degree of uncertainty or skepticism about a piece of information. This phrase conveys that while something might be suggested, there's a lack of concrete evidence or widespread agreement to support it.

Common error

Avoid overuse of the passive construction "is not believed to be", as it can sometimes weaken the impact of your writing. Consider rephrasing to an active voice construction to convey information in a more direct way. For example, instead of "The claim is not believed to be true", try "Few believe the claim is true".
