Before I go in, I must say this comment is not about politics , and I am not a Donald Trump supporter (I can't believe I have to always prefix this before saying anything sane nowadays otherwise I get stoned to death online)
That said, here's a story. One day during the presidential campaign I saw a person who normally really despised Donald Trump say "Hey I hate him but I think he kinda made sense on his speech today". Remember she watched the speech because she hated him and was looking for every chance to make fun of him but instead came off rethinking things for just that speech.
Then the next day she watched a mainstream TV news anchors go through the speech, one by one line and criticizing, using Trump's past history and etc. Then she said "I knew it he's an evil, he almost made me listen to him, so devious".
I normally never watch TV so observing someone else reacting completely opposite ways based on just a 30 minute TV show is when I realized how mainstream TV is shaping people's minds and propaganda in 2018 is stronger than ever. Most people won't want to believe that they are under heavy influence of political propaganda because their identity is connected to it, but that is the truth.
Just to be clear, this is not even about politics. This phenomenon is increasingly common across every aspect of the society. For example, if you look at what's happening in the cryptocurrency ecosystem, it's full of propaganda by people who have more knowledge manipulating people with less. The only way to overcome this is to:
1. Try to be as emotionally detached from the events as possible
2. Actually try to learn what is going on, instead of listening to what everyone else is saying, because even your most trustworthy friend, family, or even a very reputable nobel prize winner is under this influence unless they followed this principle, which most people don't have time to engage in.
3. If you ARE that reputable person, be careful what you tell your followers. If you haven't gone through step 1 and 2 and just saying "This is who I am, I'm just expressing myself, take it or leave it, just unfollow me if you don't want to hear what I say", you are being extremely irresponsible. You are basically taking your own gullibility and amplifying it to hundreds of thousands or millions of other people who are probably in less fortunate position that you are (which means they will suffer exponentially more from this misinformation than yourself)
Facebook doing this won't help fake news, it will only accelerate what they are already guilty of, because most people aren't even aware they are misinformed and furthermore don't want to believe they are wrong. So it will only result in larger and larger filter bubble which separates people even more.
It's like religion, when was the last time you were able to convince a religious person into believing that God doesn't exist? Imagine telling people on Facebook to vote whether God exists or not on Facebook.
Personally I think there's a huge opportunity hiding in this madness somewhere if you're an entrepreneur.
