Deliberate ignorance

From Conservapedia

Deliberate ignorance is the practice of refusing to consider or discuss logic or evidence disproving ideologically motivated positions. Examples include:

Howard Dean, a physician, former Governor, and longtime politician, refusing to recognize that taxpayer-funded abortion increases the number of abortions^[1]
refusing to acknowledge the inferior credentials of the critics of Richard Sternberg, whom they ostracize for having published an intelligent design article
Democrats refusing to acknowledge Barack Obama's appeal to unpatriotic donors and supporters
materialists refuse to address the impossibility of material explanation for migration and homing
evolutionists refuse to address the lack of a plausible evolutionary path for the whale^[2]
liberals refuse to address how socialism destroys productivity
abortionists refuse to address the undisclosed harm to the mothers who have abortions
Advocates of the global warming theory refuse to consider any scientific evidence which shows that natural causes have always had a greater effect on terrestrial air temperature than human activity.

Common expressions of deliberate ignorance include:

"I find that hard to believe!" (Howard Dean, June 11, 2008, in response to a fact ignored by liberals^[3])
"I'm not aware of that!" (without admitting a failure to look)
"I've never seen that in the New York Times!"
"That's not what it said in my (public school) textbook!"
"Let's talk about something else!"
"I'm not interested in that!"
"They hate us for our freedom!"
"Complete suspension of disbelief!"

Crime of Deliberate Ignorance

Deliberate ignorance can be a crime. For example, jurors were instructed "to consider whether ... former Enron Corp. executives deliberately ignored accounting fraud as the energy trader fell into bankruptcy."^[4]
