" Related to this is what is known as Othello’s error. In the play Othello by Shakespeare, the main character, Othello, assumes that his wife, Desdemona, is guilty of adultery based on her nervous response when questioned about some evidence. In truth Desdemona is innocent, but the aggressive, paranoid nature of Othello and his intimidating questions make her nervous, which he interprets as a sign of guilt. What happens in such cases is that we pick up certain emotional cues from the other person—nervousness, for instance—and we assume they come from a certain source. We rush to the first explanation that fits what we want to see. But the nervousness could have several explanations, could be a temporary reaction to our questioning or the overall circumstances. The error is not in the observing but in the decoding. "
