It should not be taken as biblical, but I have been doing these tests for nearly 40 years on myself and on others. If you own a business or manage other people, you get some very keen insight on why people react, do, or reject what is being said or done.
It's actually pretty accurate, but as I said, not biblical in the sense that everyone fits every one of the 16 categories as they test. And quite frankly, when you read about the test they state that clearly!
The second article at thoughtcatalog is actually funny. We are the 'expert scientist' and this test is not based because the people that created it are not in our little PhD brainwashed University system of 'qualifications' - so it's not real science. This sounds like the same garbage we hear from the Government Covid scammers. They need to get over themselves - actually Gov needs to quit funding these universities.
Take the test. It's GREAT insight. Take the test every decade or so and see if it changes. Most likely you won't change much if you are honest BUT you will slowly become aware of your short comings and how to compensate for them so you 'relate' to others better (or at least know when you are not going to relate if you don't change your approach).
