IQ ( the insensitive quality )

"It is clear that they know something that we don't, something that enables them to live outside of all known bounds. Strangers exist on a field that diverges from our own; most evidently, spatially, but by proxy, most certainly in terms of their inner worlds, as well. I would theorize that the thing that sets them apart from us, is some system that regulates both their physical detachment and the depth of their internal qualia. (...) It is this 'insensitive quality' that shows us just how detached strangers are from the human experience; how different from us they are." Chihun, Maeng. personal journal #1, 98


"A stranger's overall health and constitution may be summarized as its stability. Strangers that are more stable are less prone to illness, more able to thrive in their environment, and tend to display more uniformity in their behaviours, whereas less stable strangers are shorter-lived, more prone to disease and infection, and display more erraticism in their actions. Stability can also be used to estimate the average lifespan of an individual stranger — a stranger with a stability of 35%, for example, tends to reach its maximum lifespan 35% of the time." Chihun, Maeng. personal journal #17, 278


"(...) Human activity, however, does seem to be a requirement for their generation; a stranger that generates amongst the copses of urban parks never generates in the woods of the wilderness, and the strains that thrive in the harbor are unobserved in the open seas. Assuming a base population of 100,000 people, we can use prevalence to denote the likelihood of a strain's appearance. A strain with a prevalence of 100 appears in 100% of ideal environments, for example, whereas a strain with a prevalence of 66% appears only 66% of the time. As the number of people grows, so too do the strangers generate more plentifully, though – exponentially, even." Wurlitzer, Georne. personal notes, #30


"We knew, by this point, that it was not only possible, but highly likely for one of them to be present one day, only to be absent the next – even within locked rooms and sealed boxes, they came and went freely. We measured this as their constancy – or, the likelihood that any individual one of them would still be where we left it when we came back. They needed their secrecy, the same as us...we never saw when they left, we never saw when they came back." Muto, Alex. The Inaugural Collapse, 197
