I know what you're about to say....'What is this CRAAP Test, anyway?!
Internet sources don't deserve your trust. They deserve a chance to earn your trust. You will have to be picky consumer of information and put it through a process in order to believe it.
The acronym stands for:
It's a simple memorable way to remind you to look at the information you find (all of it, but especially what you find for free on the internet) with a critical eye.
This means looking at the info you find and asking it questions--Where did you come from? Who made you? Why did your writer share this online? When? And who is this information intended for? Can I find any other sources that verify this?
There is an old Russian saying, "Trust, but verify!"
