Personality models are frameworks used to understand and categorize human behavior and traits. They help psychologists and researchers identify patterns in how individuals think, feel, and act. Common models include the Big Five Personality Traits, which assesses openness, conscientiousness, extraversion, agreeableness, and neuroticism, and the Myers-Briggs Type Indicator, which classifies people into 16 personality types based on preferences in perception and judgment. These models serve various purposes, such as improving personal relationships, enhancing workplace dynamics, and guiding personal development. By providing a structured way to analyze personality, they can help individuals gain insights into their own behaviors and those of others, fostering better communication and understanding.
