And people are trained out of their skepticism. In informal conversations people react negatively when met with skepticism, people dislike those who correct inaccurate information, parents train their kids to accept their word as fact when they tire of answering questions. Most people are not inclined to think deeply or question what they are told. Ignorance is ~bliss~ strength.
There is some hope as "googling it" becomes acceptable, people are more inclined to do cursory research in informal conversations. But that's subject to bias by Google and SEO shenanigans.
I've started doing this more often in informal chats with my wife, for instance. We both kind of make half-guesses based on what we know, and then I've started thinking "I can just look this shit up on my phone real quick." I use Wikipedia for a quick answer, which is not the best source, but it's good enough for something on the fly.
Who can blame them? Distinguishing what's real from fake without diving in and doing a solid amount of research yourself seems a near-impossible task. And there's just not enough benefit to that kind of learning and effort for most people to bother with it.
