Doublethink is a concept of George Orwell's novel 1984. "The power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them." "Americans tend to define politeness in terms of "friendliness": smiling, telling "white lies", pretending to like people even if they don't." I understand why people during the communist time were afraid to say what they think but I just do not understand why the americans are afraid to say what they really thing ? what are their constrain here ?
