Review of popular source evaluation acronyms RADAR RAVEN CRAAPP by Val Magno

RADAR replaces CRAAPP test

Check Information with RADAR

R is for RATIONALE: the reason it exists.  This will also let you know what the content BIAS is.

A is for AUTHORITY: is the author an EXPERT? Who says?

D is for DATE: is it CURRENT information? Some theories change within days.

A is for ACCURACY of information: is the information you are receiving COMPLETE and IN CONTEXT, or cherry-picked and deceiving?

R is for RELEVANT: if it isn't useful for your goal, don't waste your time by reading.

If information doesn't pass a RADAR test, it is probably not worth your time.  


C.R.A.A.P.P. Test - Using humor to make learning stick.

C - urrent 
R - elevant 
- uthoritative
P- urpose - why published?
P- oint of view  - one-sided or objective?


"A group of researchers from MIT found in 2018 that stories that trigger an emotional response are shared way more than straight news stories. Added to that, neuroscientists have confirmed that we are more likely to remember stories that make us angry, sad, or laugh." Source (

Think “SHEEP” before you share.

Source - What are they about?  Follow the money.
History - Do they have a reputation to uphold? What do they risk?
Evidence - Saying something does not make it so.*
Emotion - Are they manipulating you with moral-emotional language?
Pictures - Visuals often bypass our critical thinking.

*"The most determined hoaxers or propagandists can use a network of sites or accounts to make a claim seem more widespread or well-supported than it really is."
