presumptuous
Example:
"I know John stole the money because he looks like a thief."
"I know Jessica will go on a date with me because I'm good looking."
"I'm sorry Mr. Smith, but I can’t hire you. You don't look like the type of person that can do a good job."
"My boss is a presumptuous, pretentious, conceited, arrogant, audacious, presuming, pompous asshole that thinks he knows everything!"
