The evidence is this: Words can alter perception. This is the purpose of rhetoric. For condescension to be successful the speaker must appear above his subject. Someone insecure assumes he's the worst or near the worst. By using condescension he can with words alter the perception such that he's not as bad as the subject. Thus definitely not the worst.

This isn't a water proof argument, however. A waterproof argument for human emotion isn't yet possible.
