Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Albert Einstein said that insanity is doing the same thing over and over and expecting different results?

No. Reference and fact-check sources state the saying is misattributed: Wikiquote traces its earliest known occurrence to a 1981 Narcotics Anonymous text, and Snopes rates the Einstein attribution Incorrect, finding no evidence he ever said it. Popular books and a Hansard speech merely repeat the attribution without documentation.
