I try to understand what the person making the claim must be thinking in their mind, and the best I have come up with is they are purposely try to manipulate people into spending money when they know they chances of success at the level claimed are extremely low.
For me, when I see a claim like this, I just skip the post and move one. But obviously a few fall for it.
Do you ignore most outrageous claims?
Do you worry that people might be manipulated?
