gollark: I don't think half of America actually has said as much.
gollark: I mean, sure, but to continue making somewhat unrelated meta-level claims, almost regardless of how much that's actually happening there'll still be a few people complaining about it.
gollark: The important thing is probably... quantitative data about the amounts and change of each?
gollark: Regardless of what's actually happening with news, you can probably dredge up a decent amount of examples of people complaining about being too censored *and* the other way round.
gollark: With the butterfly-weather-control example that's derived from, you can't actually track every butterfly and simulate the air movements resulting from this (yet, with current technology and algorithms), but you can just assume some amount of random noise (from that and other sources) which make predictions about the weather unreliable over large time intervals.
