impaired judgment
difficulty in forming evaluative opinions or reaching conclusions concerning available evidence, often about people and courses of action. Impaired judgment may lead to seemingly irrational actions and risk-taking behaviors. It has been thought of as both a diagnostic and a predictive criterion for delirium, dementia, and substance-related disorders, but its diagnosis and measurement are hindered by the lack of an agreed operational definition. Various fields have contributed research on this issue, including developmental and industrial psychology, experimental psychology (perception), medicine, and legal decision making.
