I believe a factor that undermines one's BS detector has to do with self esteem. Wanting to be likeable to others may make someone subconsciously willing to accept rather than reject another's BS.

Make sense to me.

In my experience the stupid generally lie as they have nothing smart to say.

You can lead a person to reason, but you can't make him/her think.

People fall for bullshit if it is repeated often enough and seems to fit what they want to hear or believe. If they think it gives their lives meaning they are on the road to having all the answers. Nobody wants to be wrong and everyone wants to have all the answers. If not now, sweety, in the sweet by and by. We see through a glass darkly now but then we will see face to face. (Up yours, Saul of Tarsus.)

The writer picks on Sixpack Chopra pretty good. I appreciate that. Because Chopra claims to have the experience, but actually he just read it out of a book.

I think maturity has a lot to do with in. In my younger days I ate up things like the Bermuda Triangle, UFOs, Bigfoot and such. By my late 20s I understood just how silly such things were, granted I studied things like debate, critical thinking, and false arguments. Frankly they should be taught in school.

Oh I agree that low education plays a big part as well as belief in the paranormal and the supernatural. A weak or strong mind also plays a part.
