While there is criticism of MBTI, it can actually be quite useful in sparking interesting conversations about work styles and preferences. It also helps people reflect on their own tendencies/behaviors in general.

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.
