HOWEVER, research into cognitive biases often require participants to report to researchers what they are thinking, and this creates a range of problems. For example, questionnaires such as the Gambling Brief Questionnaire rely heavily on the gambler being honest about what they are thinking, which could be subject to issues such as SOCIAL DESIRABILITY BIAS and DEMAND CHARACTERISTICS. This implies that the research has low internal validity and makes the research less accurate.
