There is a common psychological feature where people will uncritically believe anything that agrees with their preconceptions.
Trying to correct their mistakes often shows just much they want the falsehood to be true, as opposed to rationally weighing the evidence.
If there is one thing that President Bush is good at, it is showing just how irrational many of his critics are....
The latest is the wildly incorrect claim that Bush thought that Saddam Hussein killed Nelson Mandela. Tim Blair has a few examples. As Tim Blair has noted, the crowd who claims they are nuanced, seem woefully unable to get it.
What most people don't know, is how Saddam Hussein killed Mandela. After extensive research, I have uncovered that he did it by force feeding him a US Government supplied plastic turkey.
