The ostrich instruction is a jury instruction that the requirement of knowledge to establish a guilty mind (mens rea), is satisfied by deliberate ignorance - deliberate avoidance of knowledge.[1] This principle became established in British courts in the 1860s, and became widespread in the United States in the late 19th century.[2] The United States Supreme Court upheld it against a constitutional challenge in United States v. Jewell.[3]: 762
