Upon reflection it seems like he went overly broad with the scope of this article.
If you’ve already interacted with things like the Enneagram test, you’ll already have the context to deal with his comments.
I learned a ton from this post, perhaps it’s because I’ve had a lot of experience interacting with all the problems and challenges he lists out. I got a lot of nuggets from it in terms of insights into problems I have faced and will continue to face.
Perhaps for the less experienced, this is less helpful, as they would miss this context.
> There has been limited formal psychometric analysis of the Enneagram and the peer-reviewed research that has been done has not been widely accepted within the relevant academic communities.[5] Though the Enneagram integrates concepts generally accepted in a theory of personality,[6] it has been dismissed as pseudoscience by some personality assessment experts and called "pseudoscientific at best".[7]
