Imagine that you are a nonsmoker sharing a room with a smoker.According to the Coase theorem, what determines whether your roommate smokes in the room?
My roommate and I actually have this discussion where I'm like I'll throw paper towels in there, and she's like 'I don't think you can recycle them', she'll pick them out.
And those companies can predict someone's personality better than a coworker with just 10 likes, better than a friend or roommate with 70 likes, better than a parent or sibling with 150 likes.
Also I think as a roommate you have insider information and that might not be something you want to use. That might be something unfair to hold against.
