No of course not. But it has changed dramatically what people believe.
You mean they don't believe in things, like gods and angels, like they used to?
It is just the transmission of information. Or maybe misinformation.
As it has been since the invention of the printing press.
Not a big change in terms of what is being transmitted. Just a different way to do it.
Probably when people read newspapers they were better informed. Since most of what they read was vetted.
Free access to the internet undermines the traditional source of one's informational reality, i.e. the networks of people, traditionally your family, friends and neighbours, who believe the same thing as you do. Traditional explanations and supernatural beliefs are hard to sustain once the social structures that support them are removed.
You go away to university and suddenly almost nobody believes what you do, or did. Your siblings move to different towns, so you won’t see them so often. And your laptop plugs you into any social network that takes your fancy and leaves you free to pursue any line of enquiry that takes your fancy.
So certainly, the internet makes us much better informed.
Being exposed to the internet does not automatically make you informed. Not even close.
It is a much better way to also spread misinformation.
So the level of ignorance rises.
Until you reach a place where Trump is the Republican parties candidate.
And you know the misinformation has taken over.
This is why I'd argue that the internet does make us better informed:No given person wants to intentionally become dumber over time. The end of thinking is to solve problems and become smarter.
So let's say conversation [x] is happening on Facebook where five people are discussing a topic. They always start out at [a] which is an ignorant state, and they're always trying to move to which is a less ignorant state. This is the nature of every under-taking to learn, people are trying to become more informed, not less.
Granted, social cohesion between families and communities is a more powerful force than finding truth, and so many people are going to look for information that justifies their belief in order to maintain their social ties. However, because literally every person is actively trying to become smarter, they will in fact tend to become smarter and more informed over time.
When you multiply this process by 200 - 300 years our collective understanding of the universe usually increases dramatically.
