It's absolutely pseudo science. People love it, and it's useful as a tool to recognize "different humans problem solve differently", but like, taking it more seriously than that is a problem.
I won't pretend its perfect, but it can be a fun team-building exercise and provide common language for discussing differences.
We are working on a stealth startup which will use AI to analyze e.g. Slack messages and build out results of personality tests using methods like MBTI, so that e.g. when reaching out to someone in your workplace, you can get view a personalized overview of how to interact with that person, their behavior, how they might prefer you communicate with them, etc. Email in my bio for anyone interested, we're looking for early adopters.
In my current team we all sit down about every six months and agree how we should communicate, giving our own preferences.
After a few weeks, it's back to normal, i.e. 90% of the team making real-time interrupts in Teams, irrespective of stated preference, urgency, whether info is supplied as agreed, etc.
I don't see it being much different because an AI tells them so.
I couldn't see myself paying for something like that, anyway, but would be interested to hear your business case.
