WHY WILFUL BLINDNESS?

The elephant in the room. The idea that you're safe as long as you don't recognize the one thing that truly threatens you. I'd seen it in people who smoked and knew they shouldn't, others who never opened their credit card bills, in marriages where you knew one of them was having an affair.
