Carl Sagan claimed that scientists have a natural “baloney detector” when presented with something new. He really just describes how scientific method should work but it isn’t half applicable to the stuff the internet throws at us every day.
Speaking of which, hello, this is the internet throwing stuff at you. But take a look first at the Brain Pickings article about Sagan’s detector notion, it’s good. And it includes links out to finding the book where he first said this.
