Milo Yiannopoulos (left) is an entrepreneur and the author of the book The Sociopaths of Silicon Valley. For the past 3 years, he has lived what he calls a data-driven social life. Specifically, he maintains a database of 746 friends, family members, and acquaintances. The above image is a screenshot of that database.
Each member has a relative value to Yiannopoulus's life assessed by certain criteria. He explains the system in The Kernel:
The scores are normalised across the whole group. This enables me quickly and easily to drill down and generate lists from which I can craft the perfect party. I can even engineer how the photos will look, since I have a column that covers personal style. Politics is covered by a simple “Pass” or “Fail.” […]
My close friends (Tier A) tend to have high IQs, but their partying, troublemaking, and strategic values don’t follow any patterns. All of which implies that I am attracted to pretty, smart people with sound politics, but I don’t particularly care whether or not they are wealthy or like to party.
