Willful Blindness

So put in your earplugs
Put on your eyeshades
You know where to put the cork
--The Who

You will often hear people say "I'm no expert but..." They then proceed to weigh in on discussions with air of authority. If the discussant's argument's fail, then hey, no problem, because "I wasn't an expert anyway."

Why not develop expertise? An advanced degree is not required. Only appetite for truth and willingness to engage one's brain.

The risk for many people is that their quest for truth will reveal that their previously uninformed views were mistaken.

People hate to be wrong, so they remain willfully blind.
