I have been having a "discussion" in The Science Enthusiasts group in Facebook. Someone posted another "debunking the MBTI" article (from 2014). Surprisingly, this one doesn't cite "Wharton Scholar, Adam Grant".
The article includes this statement: "Several analyses have shown the test is totally ineffective at predicting people's success in various jobs, and that about half of the people who take it twice get different results each time."
Well, yes. Both of those things are, at least partially, true. Neither, however, is an argument that "debunks" the MBTI.
