If what you meant to say is: "it's a bad idea to promote people based on their MBTI", then I wholeheartedly agree with you. There's no such thing as "getting a good grade on the MBTI". A particular type does not predestine someone to be good at a particular job. If what you meant to say is: "MBTI is a bad thing and should go away", then I completely disagree. MBTI is popular among many companies because it's an effective shorthand for: "here's how I think and how I like to work". In environments where people need to work in many teams and many people, it speeds up getting over basic communication hurdles. Most people in the work environment do not have good communication skills, and are not naturally adept at understanding what other people are saying, or mean. I've seen a conversation about MBTI be part of the training on how to communicate and collaborate.
