Personality is shaped by both hereditary and environmental factors and refers to how a person interacts with and reacts to others. The Myers-Briggs Type Indicator (MBTI) is a widely used personality test that classifies people into 16 types based on their preferences in four dimensions: extraversion vs introversion, sensing vs intuition, thinking vs feeling, and judging vs perceiving. The Big Five personality model assesses personality along five dimensions: extraversion, agreeableness, conscientiousness, emotional stability, and openness to experience. This model aims to explain how personality traits influence behavior in organizational settings.
