Expert writing Tips
Best practice
When using "is not corroborated", ensure you clearly state what lacks corroboration and, if possible, why it lacks support. For example, "The witness's statement that John was at the scene is not corroborated by any other witness or surveillance footage."
Common error
Avoid using "is not corroborated" as a definitive dismissal of a claim. Instead, present it as a lack of sufficient supporting evidence at the current time. For example, instead of saying, 'The theory is false because it is not corroborated', try 'The theory remains speculative as it is not yet corroborated by empirical data'.
