In terms of the content, I was hoping for more concrete data rather than speculation. I myself come from a worldview where this is somewhat alien, in that, in my understanding of Christianity I am not trying to be this big achiever that the article wants to be. Likeability however is not directly a virtue in itself for us, and indeed our other virtues like being present in the moment and authentic with others sometimes require unlikeable conversation, for example “hey, I noticed that you have been on your phone composing this post to tell someone on the internet that they are wrong for about an hour, and I don't think you are getting as much out of that as maybe you seem to think... maybe let it go and let them be wrong and have the last word and trust that onlookers will judge properly without trying to sway their judgment?” rarely goes over well until sometime gets some more distance from the addiction.
So, like, I would have been really interested in the precise deployment of unlikability to further wisdom, but this article is about the shotgun deployment of unlikability to further personal achievement.
