	Kun: “Mathematicians, regardless of who is actually right, [are] not only willing to accept they’re wrong, but eager enough to radically switch sides when they see the potential for a flaw in their argument.”
	Warnick: “Mathematicians leave their ego at home.”

	Consider the claim, “we should teach handwriting in school.”
	With your neighbor, each pick a side and start arguing
	When one of you gets stuck, switch sides
	See how long you can keep going
