Okay, this is going to be incredibly dense with resources, and long (just a warning that this ain't something to dive into while you're waiting for your pasta to cook. And now you know what I do while cooking these days).
We've talked about social media metadata - your psych profile - and why it wasn't just a few points of data that Cambridge Analytica stole for Donald Trump. https://twitter.com/i/moments/984259305732964352
We've talked about how it was more subtly weaponized against the left https://twitter.com/i/moments/978819806089670656
But we haven't talked about WHY these techniques work. I'm hearing the narrative "microtargeting/psychological profiling is snake oil." Well, that's bullshit. If that were true, why would they even bother to steal all our metadata?
FB's whole business model is dependent on this "snake oil." Businesses wouldn't have billions in social media ad spend if it weren't effective.
Okay, now let's dive into the nitty gritty of how this stuff works. Let's talk about the autonomic (involuntary) response + the lizard brain.
The part of your brain that initiates fight or flight is called the reptilian brain. This part also controls feelings of *territoriality and competitiveness.*
Marketers are well aware of the reptilian brain. Here are a few articles outlining how to appeal to the reptilian brain (they also fully acknowledge that one way of doing it is scaring people) https://www.forbes.com/forbes/2006/0703/044.html#52c13524511d
Musicians deal with their reptilian brain/fight or flight response extensively: one form of it is stage fright. If you've ever performed, or get nervous speaking, or played sports, you probably know what I'm talking about.
Your mouth might get dry, your hands might shake. You might start to sweat, or have butterflies in your stomach.
During my music training, we spent a lot of time learning to combat this. One teacher I had made us run up and down stairs, and then train ourselves to lower our heart rate and slow our breathing before we played.
When experiencing stage fright, your lizard brain thinks you're in danger when you're actually not. Your body starts to react as though you may need to defend yourself, or to escape. It floods with adrenaline in preparation, causing the shaking hands, etc.
The thing with performing and stage fright, though, is that you're aware that what you're experiencing has a definite beginning and end. As soon as you finish that audition, play your solo, or give your talk, you'll be done and feel normal again.
And knowing there's a beginning and end to the stage fright allows you to proceed even though you're terrified.
Well, what if you didn't know when it might end? When the reptilian brain is engaged, information can't reach the frontal cortex of the brain, where logical thinking occurs. What if your reptilian brain is engaged constantly, for months, or even years?
What if you were a target of psychological warfare?
Let's take a look at some of the actual online content surrounding this administration.
And, remember: they had STOLEN psychological profiles of just about every American. They had everything we've done, said or felt on Facebook. They knew *exactly* who to target, and *how.*
You probably remember this from the NRA:
Let’s also talk about social proof and the reptilian brain—another thing marketers love. Social proof is basically people saying how they feel about something, and others being influenced to feel or act the same way (or at least pretend to). https://blog.kissmetrics.com/social-proof/ 
To be clear: this wasn't a matter of buying a few ads. It was psychological warfare. The purposeful terrorizing of populations.
People are mystified at how Trump supporters can't see the forest for the trees. Well, they were brainwashed, and are still being brainwashed. They're genuinely afraid (you've seen the crying nazis), and paranoid.

(This is NOT a free pass for them. At all.)
In summary: this is STILL a BFD. This shit works; if it didn't, they wouldn't have taken the risk and invested billions of dollars in this operation. The way to claw our way out of this pit is with awareness, critical thinking, compassion and remembering our shared humanity.
