Expert writing Tips

Best practice

Use "was doubtful" to express a moderate level of uncertainty or skepticism. It's stronger than "was unsure" but less definitive than "was certain it wouldn't happen".

Common error

In highly formal or academic writing, consider stronger, more precise alternatives like "questioned the validity of", "expressed reservations about", or "found unconvincing". "Was doubtful" can sometimes sound too informal for certain contexts.
