traue keiner Statistik, die du nicht selbst gefälscht hast
German
Etymology
Unknown. Literally, “do not believe any statistic that you haven't forged yourself". While commonly attributed to Winston Churchill, there is no proof and the proverb is completely unheard of in the English-speaking world. It was later hypothesized that the mistaken attribution was intentionally created as Nazi propaganda to discredit Churchill. The first use of this proverb is attested in 1946.
