...the truth probably lies somewhere in the middle.
If we only hear an issue from one side or the other — regardless of the issue — we live in an ‘echo chamber’ (to coin a phrase from another post).
I'm all for hearing from people who make you a bit uncomfortable. The trouble comes when fringe nutters are given equal standing on grounds of "fairness"with people with evidence on their side, it can give the fringe a credibility they don't deserve. The BBC is particularly prone to this as it has an obligation to be "fair" (and on one reading caused Brexit). I like the idea that a journalist is not being fair when they give a hearing to someone who says it's raining and somebody who says it's sunny - it's their job to stick their head out the window and see if they get wet.
Obviously it's not always that easy when it comes to complex, incomplete science but the truth is not always somewhere in the middle, it can be as near as dammit right over on one side.
If one person swallows misinformation and passes it on to three others, that implies an R of 3.0 - we need to use all our tools to get R<1 and achieve what has been called "nerd immunity".
We all need to be aware that "social media" is driven by this kind of channeling. The companies do not intend to create wingnuts and nutters but the advertising algorithms have one job which is to keep you focused on the app. Then they can sell you to their real customers, the advertisers.
This naturally leads to a situation where you are offered, say 5 items to read and you like 3 of them. The next time you come back they offer you 5 more items that all share similarities to the 3 you've already ready read and reacted to. In a very short time you are only being offered information that falls into one category and becomes more an more focused on one or two traits. Hence you hear stories about people going online to search for information on a new hair style for their 14 year old daughter and somehow end up on skinhead sites denying the Holocaust ever happened and the story about Anne Frank is a left-wing fiction piece (and beginning to believe it).
People can be easily manipulated and in the constant search for profit many online companies use this as part of their business plan.
I know I sound like Grandpa when I say this but I miss the days when each town had a Liberal and a Conservative Daily paper. Subscribe to both and read for the overlap. The overlap was closest to the truth. Media consolidation has created the echo chambers. They sell the company line with little regard for any truth.
We live in amazing times, in very troubled societies.
Stay safe, stay well and take care of those around you.
