Among the Sioux Indians of South Dakota, it is regarded as incorrect to answer a question in the presence of others who do not know the answer. Such behavior would be regarded as boastful and arrogant, and, since it reveals the ignorance of others, it would be interpreted as an attempt to undermine their confidence and shame them. In addition, the Sioux regard it as wrong to answer a question unless they are absolutely sure of the correct answer. Faced with a classroom of Sioux children, a white American teacher who is unaware of their culture might easily interpret their behavior as a reflection of ignorance, stupidity or hostility.
