Suppose person X is looking for something he has lost. Instead of thinking he left it somewhere, he is convinced that person Y has taken it. X is so convinced of this that he will not even look for the object. Instead, he badgers person Y for the location of said object.
In another example, person X is sitting in the rear of a vehicle. He feels cold. The temperature for the rear of the vehicle is controlled by a panel of buttons immediately in front of X. Instead of changing the temperature, he gets angry at person Z. His first instinct is to assume that person Z changed the temperature so he would be cold.
This behavior almost reminds me of Capgras syndrome. Person X attributes every negative circumstance to the malevolent intent of another individual, usually someone close to him he fears or sees as oppressive. He thinks of most people around him this way, and he sees himself as their victim. X responds this way to everything: lost items, a hamburger served differently than he ordered it, tripping and getting hurt, changes in cellular reception while driving along a freeway, etc. While some of these may be someone's fault, he attributes fault to the wrong person.
Is there a name for this type of behavior?
