The other is refusal to understand what is being said. This is sometimes called a 'straw man' argument. In my experience, this is THE most common way to 'win' a debate with a bad argument. One simply never, ever understands the good argument. And since psychology is not a science, there is no way to prove that someone is pretending when they appear not to understand.
