Fundamental traits are the basic characteristics that define an individual's personality. These traits are often stable over time and influence how a person thinks, feels, and behaves in various situations. Common frameworks for understanding these traits include the Big Five Personality Traits, which encompass openness, conscientiousness, extraversion, agreeableness, and neuroticism. These traits can be measured through various assessments and are used in psychology to predict behavior and interpersonal relationships. Understanding fundamental traits can help individuals improve self-awareness and enhance communication with others, making it a valuable tool in both personal and professional settings.
