I have only seen this in practice once at a little hedge fund called Bridgewater. It sounds like you are making assumptions of what you think the testing is without any frame of reference.
Also, anger is an emotion opposed to a personality designation.
ok, and? We've also seen "how many pingpong balls can fill a school bus" from the likes of Google. They eventually learned it was not a good filter. If a personality test truly is better, I want to know because I'm involved with hiring at my company.
What qualifies Bridgewater's take on this? How have they leveraged it and to what effect? Correlation, causation, all that jazz too - if I want to be taller, I should obviously play basketball.
[edit] you edited your response as I posted mine :)
Yes, I'm assuming what a personality test is because you've given us very little to go on. Give us more. Honestly, if it is better, I'm sure others want more than "this practice is good." We want to know how, what, and why.

Then I recommend getting in contact with a behavioral health professional.

Their success and retention.
When I went through the Bridgewater process there were about 6 different personally tests I took. Some were more precise than others. I measured a 96% objectivity score which is a statistical anomaly. I ultimately dropped out as I found a less risky position in my local metro far away from the east coast.
There are companies with practically zero attrition rates and are successful; lots of companies can claim what you are claiming. Again, what you are saying is the same as "if I want to be taller, I should play basketball."
Then you should gather your own data and independently draw your own conclusions.
In my experience selective bias cannot be avoided unless you remove humans from the initial selection process. It is also my experience that potential in a given field is a predictable quality not discerned from resumes.
