In case you're feeling ignored... I hope you read some of the posts that followed this post of yours. Although they weren't directly targeted responses to you, they do address some of the points you brought up.
1) (and most significant) The cult of personality article discusses churches using the personality profiles badly. Certainly, if you use personality profiles to judge a person and try to pigeon hole them and ignore who they really are, you can't love them. Since God commanded us to love one another, you bet we can't use personality profiles to judge other people.
2) There are many modern medicines that use the same herbs that the eastern cultures have been using for hundreds of years. Does that make them occultish? Should we avoid those medicines because they use herbs that were used for occultish purposes?
3) These papers look/read like something a college student would have written in their spare time. What gives these papers so much (any?) weight as being truth?
If you'd like to present your own interpretation of these articles, I would love to address them too. But so far, there doesn't seem to be any truth regarding personality testing; furthermore, there doesn't seem to be anything addressing MB typing specifically.
When used properly, these tests provide a means to not only understand ourselves, but to accurately describe ourselves to others; making us more effective in all aspects of life, but especially in our interpersonal communications. And isn't that a huge part of life? Loving each other, creating and nurturing those connections?
