How do you know someone really accepted Christ and isn’t just saying it? What if they do it wrong? Protestants don’t believe in salvation through works, so you can’t even use their behavior as a check.
Hi, Evangelical Christian from across the Atlantic here. Just wanted to point out that the traditional Protestant doctrine of “salvation through faith, not works” does not mean that you cannot use behavior as a check. Based on texts such as Matthew 7.15-23 (“So every good tree bears good fruit, but the bad tree bears bad fruit”) or James 2.14-26 (“show me your faith without the works, and I will show you my faith by my works”), many Protestants (and Evangelicals) consider that true faith will necessarily induce personal change leading to “good works”. So someone who says they believe but does not exhibit behavioral improvements would not “really know Jesus / have made the handshake”.
In the words of John Calvin (who was pretty stuck on salvation by faith alone):
“It is therefore faith alone which justifies, and yet the faith which justifies is not alone: just as it is the heat alone of the sun which warms the earth, and yet in the sun it is not alone, because it is constantly conjoined with light.” (forum where I found the reference, along with several other helpful quotes from Luther and historic Lutheran confessions)
From my understanding, this is the majority view among Protestant theologians in history (and probably today as well). However, the very peculiar Evangelical culture in the US, especially in corners that devalue theological study (as described in the article; often non-denominational), and the simplifications that come with it, have given some prevalence to views such as the one you describe.
Otherwise, I had lots of fun reading this, thank you for making that bridge! I have heard many Christians criticize the start-up mentality of church planting, but its nice getting this from an outside view.
Very interesting post. It would be nice to formalize a model with the existing ideas from behavioral game theory (Cognitive Hierarchy Model / level-k thinking / endogenous depth of reasoning), with the added cooperative dimension (caring to minimize the cognitive cost for the other). (As some suggest in the comments ask-culture may be an equilibrium?)

And of course this is all very related to theory of mind in psychology. On that note I once read in a lecture by Robin Dunbar (Mind the Gap; or Why Humans Are Not Just Great Apes) that for most people the highest level they can reach is 5. The relevant paragraph:
