But depending on how you shape that information flow, you can create pretty weird outcomes because it allows for straight up wrong information to be consolidated in such a way that it might appear "true".
The Internet (social media to be more specific) has helped people with fringe ideas to connect with each other on a global basis, regardless of how fringe these ideas might be.
Pre social-media these "fringe believers" used to be so fractured and compartmentalized, limiting their influence and general visibility quite much.
Social media has allowed for these fringe believers to find each other, not just allowed, it's pretty much motivated it by personalizing what content and users get surfaced to them.
To put it in not so nice terms: Facebook has facilitated a situation where individual town-idiots unite on a global scale, this allows them to shape the public discourse in ways they haven't been able to before.
Case in point: People throwing around the term "cultural Marxism" these days like it's the most normal thing in the world. When "cultural Marxism" is basically just a reframing of the age-old Nazi conspiracy theory about the "International Jews controlling everything".
Not too long ago you could easily disregard people spreading such memes, as they were rare and single individuals. This doesn't work anymore because the idea of "cultural Marxism" being an actual thing has now been legitimized through massive social media echo chambers.
The sad part is that many of these people often don't even know what they are regurgitating because they get all their information just from their social media feeds. A quick google search of "cultural Marxism" should be able to educate anybody in a matter of minutes, but that would involve effort while "+like" and "share" barely requires any effort and is the far more appealing course of action when users see something that reinforces their beliefs.
