Anecdotal evidence is a term used to describe information or data that is based on personal experiences or observations and is not necessarily part of a larger, more comprehensive analysis. When looking for synonyms to describe this type of evidence, one might consider the phrases "first-hand accounts," "personal testimony," "unsubstantiated reports," or "casual evidence." Other possible synonyms include "subjective evidence," "hearsay," "anecdotal reports," or even "anecdotes." It is important to note that while anecdotal evidence can be useful in certain contexts, it should not be relied upon as the sole basis for decision-making, as it may be biased or incomplete.
