The Myers-Briggs Type Indicator (MBTI) memes capitalize on the 16 personality types categorized by Katharine Cook Briggs and Isabel Briggs Myers. These memes often personify the four-letter codes, such as INFP or ENTJ, using relatable archetypes and stereotypes like the 'mysterious introvert' or the 'chaotic debater.' Popularized on platforms like Reddit and Tumblr, the memes serve as a cultural shorthand for users to discuss social anxiety, cognitive functions, and relationship dynamics. By turning complex psychological theories into humorous relatable content, the MBTI meme community has created a massive niche where people find belonging through their shared personality traits.
