The Week offers four simple steps to avoid being taken in by an internet hoax. They are pretty obvious, like the "check out what you've read with other sources" think. To me that's kind of a "duh," but I used to be a reporter and the crusty old salts who taught our classes used to say, "If your mother says she loves you, check it out first."
I'm afraid that the four steps, while useful, can't guarantee that someone will never get taken in by an internet hoax again. There's only one such method, which the writer omits, but which I will include as the fifth step: Don't ever get on the internet.
Well, that one's blown.
