Proof by intimidation (or argumentum verbosium) is a jocular phrase used mainly in mathematics to refer to a style of presenting a purported mathematical proof by giving an argument loaded with jargon and appeal to obscure results, so that the audience is simply obliged to accept it, lest they have to admit their ignorance and lack of understanding.
In order to overstate one's potential for aggression, battle cries need to be as loud as possible, and have historically often been amplified by acoustic devices such as horns, drums, conches, carnyxes, bagpipes, bugles, etc. Battle cries are closely related to other behavioral patterns of human aggression, such as war dances and taunting, performed during the "warming up" phase preceding the escalation of physical violence.
From the Middle Ages, many cries appeared on standards and were adopted as mottoes, an example being the motto "Dieu et mon droit" ("God and my right") of the English kings.
Usage of this phrase is for the most part in good humour, though it also appears in serious criticism.
"Proof by intimidation" is also cited by critics of junk science to describe cases in which scientific evidence is thrown aside in favour of a litany of tragic individual cases presented to the public by articulate advocates who pose as experts in their field.
It is said that this was Edward III's rallying cry during the Battle of Crécy.
