Korean personality types are often categorized using the MBTI (Myers-Briggs Type Indicator) framework, which includes 16 distinct personality types. Each type is defined by four dichotomies: Introversion vs. Extraversion, Sensing vs. Intuition, Thinking vs. Feeling, and Judging vs. Perceiving. This system helps individuals understand their preferences in social interactions, decision-making, and lifestyle choices. Another popular classification in Korea is the Blood Type Theory, which suggests that a person's blood type can influence their personality traits. For example, individuals with Type A blood are often described as organized and responsible, while those with Type B blood are seen as creative and free-spirited. This theory is widely discussed in social contexts and can shape perceptions of personality in Korean culture.
