Wasn't this guy one of those "zizian" nutjobs?

Ziz believes there are two kinds of core, "good" and "nongood". "Nongood" cores are the most common (about 95% of the population). A "nongood" core is one that only grants full agency when dealing with issues of self survival or protecting offspring. This is enforced by a filter that only unlocks full agency when it detects those objects in a situation. Sometimes this filter breaks, producing a "good" core. Because people have two cores, there are three basic alignments: "nongood", "single good", and "double good". "Single good" is about 5% of the population, having one broken core which allows limited altruistic agency. Ziz seems to believe the probability of cores breaking is independent. That means the "double good" alignment only occurs in one fourth of one percent of people. This is important because double goods are the only people who can have full altruistic agency in Ziz's worldview. In this model "core" cannot be changed and you're stuck with the morality you have. This is important to consider in later sections where we talk about what Ziz tells people about their cores.
Reddit would be outraged about an 18 yo dating a 16 yo, though. Some people have really weird and unrealistic views on this
