Roy Sorensen agrees with Carson that lying does not require an intention to deceive, and that there can be non-deceptive “bald-faced” lies (Sorensen 2007) and “knowledge-lies” (Sorensen 2010). However, he rejects L12, since it entails that one cannot lie when the falsity of what one is stating is common knowledge: “Carson’s definition of lying does not relieve the narrowness. The concept of warrant is not broad enough to explain how we can lie in the face of common knowledge. One can warrant p only if p might be the case. When the falsehood of p is common knowledge, no party to the common knowledge can warrant p because p is epistemically impossible” (Carson 2007, 254). According to Sorensen, a negotiator who tells “a falsehood that will lead to better coordination between buyer and seller” is telling a bald-faced lie (Sorensen 2007, 262).
