1. A computer-implemented method of evaluating information confidence based on cognitive behavior indicators of a user, the method comprising: determining, by a processor, a system generated answer to a question in an active learning question and answer system, wherein the system generated answer includes a first answer confidence score for the system generated answer; querying a user for an answer to the question in the active learning question and answer system based on the first answer confidence score; receiving, by the processor, information from the user as an answer to the question in the active learning question and answer system; monitoring, by the processor, the user for one or more cognitive behavior indicators when the user is providing the information, wherein the one or more cognitive behavior indicators comprise one or more biometric measurements of the user at a time the information is provided by the user and measures of an influence of an external stimuli on the user at the time the information is provided by the user; determining, by the processor, a second answer confidence score for the information received from the user based on the one or more biometric measurements of the user and the measures of the influence of an external stimuli on the user; annotating, by the processor, the information with the cognitive behavior indicators, a user profile associated with the user, and the second answer confidence score; and updating the first answer confidence score based at least in part on the second answer confidence score.
