I dont follow this topic that much, it would be best to watch the video and assess for yourself how well the MBTI types described match their personalities. Keep in mind that the MBTI is just one of many personality assessment tools, and its accuracy and reliability have been a subject of debate among psychologists and researchers.
Furthermore, it's important to remember that public figures like BTS members might present a certain image to their audience, which may not fully represent their true personalities in private or personal settings. MBTI or any other personality assessment is not an absolute description of an individual but can offer some insights into their preferred cognitive processes and behavioral tendencies.
If you're interested in understanding BTS members' personalities better, it might be helpful to look into various interviews, personal statements, and interactions they have had over time, as well as their creative works and individual pursuits outside of their group activities. However, always approach these interpretations with a critical and respectful mindset, as celebrities deserve their privacy and have the right to present themselves as they see fit.
