Expert writing Tips
Best practice
When using "on speculation", ensure that the context clearly indicates the absence of concrete evidence or factual basis. This clarifies that the statement or action is based on conjecture rather than verifiable information.
Common error
Avoid using "on speculation" when the basis is actually an informed prediction derived from data analysis or expert opinion. Speculation implies a lack of concrete evidence, so using it in place of informed analysis weakens the credibility of your statement.
