“One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.” ~Carl Sagan, in The Demon-Haunted World: Science as a Candle in the Dark ©1995
An aside: I looked up the origin of the word “bamboozle,” and found out it’s been around since the 17th century. For some reason I always thought it was slang from the 1940s.
