Planet X and the Baloney Detection Kit

Environmental Science Journal Planet X and the Baloney Detection Kit

The Baloney Detection Kit is a set of questions that a famous astronomer named Carl Sagan suggested be applied to any extraordinary claims. Here is a summary of the questions in the kit:

1. 
   How reliable is the source of the claim?
   
2. 
   Has the source made other, similar claims?
   
3. 
   Has the claim been verified by someone else?
   
4. 
   Does the claim fit with how the world works?
   
5. 
   Has anyone tried to disprove the claim?
   
6. 
   Where does all the evidence point?
   
7. 
   Does the claim follow the rules of science?
   
8. 
   Is there any positive evidence?
   
9. 
   Does the new theory account for all phenomena, or just one?
   
10. 
    Are personal beliefs driving the claim?
    

Now consider the prediction that Nibiru, or Planet X, is heading toward an eventual collision with Earth, resulting in our planet’s complete destruction. This idea largely came from a woman named Nancy Leider, who claims that extraterrestrials can communicate with her telepathically through an implant in her brain. Pick any three of the questions from the Baloney Detection Kit and apply them to this claim.
