I think these things are dangerous, and I think that guy needs a better work environment. I manage people, I do a lot of personality profiling too, from belbin to mbti and disc profiles to our own HR departments people tools, and they are largely as useless as horoscopes at defining people.

Everyone is a bit of everything, and the point of realizing or learning things about yourself, such as the fact that you’re more introverted than extroverted isn’t to say “oh well, I guess I’m an introvert” and then define yourself around that. The point is to figure out what your strengths and weaknesses are so that you can work on bettering both.

That’s not what always happens though. Some people do these tests and learn nothing about themselves or how to be themselves. They read that they are introverted and then they google what that means, and then they start becoming more and more like what their google results told them.

I see nothing in those slides that aren’t an exploitation of this.

Obviously you need safe spaces and concentration zones at a workplaces for people who primarily use their brains. But are you seriously trying to tell me that “extroverted” programmers don’t need places where they aren’t distracted? I’d say people with more extroverted traits need those even more, as they get distracted easier and are worse at setting up the “do not disturb” boundaries by themselves. Obviously you need to manage people differently. Some people won’t speak up as much and it’s import to make sure they feel heard, but even people who speak up, might not feel heard or come up with a better “come back” two hours later, and there needs to be room for all of that. Typically the how depends a lot more on the day/situation than what their “personality profile” is like.
