Best practice
Ensure that the context aligns with the intended meaning. If you are choosing not to disclose information, acknowledge that decision explicitly rather than implying a lack of knowledge. For example, instead of "I cannot say if the project will succeed," consider "I am not at liberty to discuss the project's potential outcomes."
Common error
Avoid overusing the phrase "I cannot say" as it may come across as evasive or insincere. Instead, provide a brief explanation when possible, or use a more transparent alternative such as "I'm not at liberty to say" to maintain transparency.
