of a double bind is two conflicting demands, each on a different logical level, neither of which can be ignored or escaped. This leaves the subject torn both ways, so that whichever demand they try to meet, the other demand cannot be met. "I must do it, but I can't do it" is a typical description of the double-bind experience. For a double bind to be effective, the subject must be unable to confront or resolve the conflict between the demand placed by the primary injunction and that of the secondary injunction. In this sense, the double bind differentiates itself from a simple contradiction to a more inexpressible internal conflict, where the subject really wants to meet the demands of the primary injunction, but fails each time through an inability to address the situation's incompatibility with the demands of the secondary injunction. Thus, subjects may express feelings of extreme anxiety in such a situation, as they attempt to fulfill the demands of the primary injunction albeit with obvious contradictions in their actions. This was a problem in United States legal circles prior to the Fifth Amendment to the United States Constitution being applied to state action. A person could be subpoenaed to testify in a federal case and given Fifth Amendment immunity for testimony in that case. However, since the immunity did not apply to a state prosecution, the person could refuse to testify at the Federal level despite being given immunity, thus subjecting the person to imprisonment for contempt of court, or the person could testify, and the information they were forced to give in the Federal proceeding could then be used to convict the person in a state proceeding. History The term double bind was first used by the anthropologist Gregory Bateson and his colleagues (including Don D. Jackson, Jay Haley and John H. Weakland) in the mid-1950s in their discussions on complexity of communication in relation to schizophrenia. Bateson made clear that such complexities are common in normal circumstances, especially in "play, humour, poetry, ritual and fiction" (see Logical Types below). Their findings indicated that the tangles in communication often diagnosed as schizophrenia are not necessarily the result of an organic brain dysfunction. Instead, they found that destructive double binds were a frequent pattern of communication among families of patients, and they proposed that growing up amidst perpetual double binds could lead to learned patterns of confusion
