@cryptogee,

The fact remains that people who believe in the moon landing hoax theory are suffering from confirmation bias.

That's not all they're suffering from.

These people aren't believing it because they are (necessarily) crazy or stupid.

Your reputation for generosity proceeds you. :-)

You're right, of course, confirmation bias is one of our mind's greatest deceits (amongst many others). Despite the phenomenon being well known and understood, I am always astonished by how few people will actually challenge their own beliefs: "What do I believe and why do I believe it?"

Is having a brain and refusing to use it, any different than not having one at all?

To quote a great philosopher, "Too often, we enjoy the comfort of opinion without the discomfort of thought."
