Mind worms

One time, in the ER, a man from Mexico came in complaining of a severe headache. We did a CT scan, and put it up on the viewing screen, and there, plain for anyone to see, were the trichinosis worms in his brain. Anyone walking by reacted the same. "Eeeewww. No wonder his head hurts".

Social media like Facebook and Twitter are the way that our ruling overlords scan the body politic and see how our minds work.
If they put out a particularly ridiculous brain worm, say....
"If an American president meets with a foreign leader, that bestows legitimacy upon that leader'',
or ''$40,000 in ads on Facebook can overcome a $2 billion election'',
and millions of people accept that as some sort of credible idea and immediately start repeating it to their friends, as if they are being logical, then our monitors can see that, right there on their viewing screens.

And then they know that a certain percentage of Americans are idiots, and they react the same way...
"These people will fall for anything! Let's tell them again that 'Assad is gassing his own people'! and then go bomb Syria again. They'll believe it, they believe anything".

"If they can make you believe absurdities, they can make you commit atrocities". Voltaire
