It’s a vaccine that needs daily boosters.  In an interview with
Stephen Colbert, Neil Degrasse Tyson made an interesting comment
that has since gone viral as an internet meme. Colbert asked
Tyson if science was a way of approaching the world, and he
responded,  It’s not only a way of approaching the world, it’s a
way of equipping yourself to interpret what happens in front of
you. I think of science – the methods and tools that enable it –
as kind of like a utility belt that you walk around with.
…Science literacy is vaccine against charlatans of the world
that would exploit your ignorance.  This last remark merits
consideration both because of its huge popularity and because of
how manifestly untrue it is. We should be wary of this kind of
self-congratulatory attitude, because it blinds intelligent
people to the possibility–or rather, the inevitability–that they
could be wrong. Smartness is not an inoculation against magical
thinking.  My attention was first drawn to this fact by none
