Expert writing Tips

Best practice

When using "not confident about", ensure the object of your uncertainty is clearly specified. For example, "I am not confident about the project's success" provides more context than "I am not confident."

Common error

Avoid using "not confident about" when a stronger expression of certainty is appropriate. For instance, instead of saying "I'm not confident about whether the Earth is flat", use "I am certain the Earth is not flat" to reflect the near-impossibility of the Earth being flat.
