Personality types refer to the different ways in which individuals may behave, think and feel. It is based on the idea that there are distinct patterns or traits that can be observed in people's behavior, often referred to as personality dimensions such as introversion/extroversion, openness/closedness, conscientiousness, agreeableness, and neuroticism (also known as the Big Five personality traits). These patterns are generally considered to be relatively stable over time and across different situations. People may also use other models or frameworks to describe personality types such as Myers-Briggs Type Indicator, Enneagram, or astrological signs. Understanding one's own personality type can help individuals better understand themselves, their strengths, weaknesses, and how they interact with others. It is also useful in various settings such as career counseling, relationship advice, team building, and personal development.
