I don't think it's that we're post-fact in the sense that data in unverifiable; most data is verifiable. But there are enough websites and online communities out there to support any point of view, so that people find a peer group that supports their theory, especially one's fears on this complex world. Anti-vaxxers are a huge example of this. Try to find information about specific vaccines and you'll be deluged in anti-vax pages that sound rather scientific. The information is out there, but so is the disinformation.
