This post is a case study of the phenomenon described in Coalitions Between are made by Coalitions Within. If you haven’t read that post, this post may seem vague, but I’m talking about a very precise phenomenon. Having said that, if you like to start with concrete examples before moving to abstractions, you may enjoy starting here instead!
While working on that piece of writing, I had a fascinating conversation with a Born-Again Christian guy preaching with a megaphone at a Sunday fair. While my wife went to get the car, I approached him to find out what his deal was.

Fun fact about me: I’ve long found it helpful to talk to street preachers once a year or so, as a gauge on my ability to stay relaxed and grounded and open-minded while talking with someone who is trying to persuade and argue with me. This guy in particular was very aggressive compared to eg the chill Jehovah’s witness in Alamo Square last year… both in his use of the megaphone and in his loud declarations that everybody was sinners and needed to repent.
I opened with a simple question: “What does ‘repent’ mean?” He talked about it as a turning, a change of heart—and clarified that of course he meant the specific change of heart of accepting Jesus. Implied but not stated was that this also would include accepting and following the moral interpretations of the Bible that his particular church adheres to.
Rather than endure the tedium of him trying to convince me to change in some particular unlikely way, I figured I’d make much more headway in mutual understanding by asking him about his story of repentance.
He described his pre-conversion life as “living sinfully” — naming things like alcoholism, gambling, lying — a collection of self-destructive behaviors. And he felt totally out of control, and out of nowhere tried praying for relief, and suddenly had a breakthrough where by the Grace of God he became a righteous man (and joined some nearby available church).
It seems to me that essentially enough parts of him recognized that this shift would be a net win, compared to his existing self-destructiveness, that a new inner coalition was able to form and rule his psyche—with the support of this church etc. Which is not to say that all of his subsystems are happy with the new situation, but it’s at least a stable struggle, not a total race to the bottom. Christianity, classically centers around a struggle with temptation—found extensively in the writings of both Paul and Augustine, whose conversion stories could also make very interesting case studies for fractal coalition theory, and may yet.
I asked how it reached him, where his sense of conviction came from. He said he grew up hearing about the gospel—people came door to door to their house. I asked why he went with street preaching, because it seems like maybe the door-to-door thing would work better. He said they’d tried a lot of different things. I’m not sure how they were measuring their success but on that level it sounded kind of empirical.
I asked him about his theory of change: given the intention to convert people, why did he think the best approach was to yell loudly to people who seemed uninterested?
