When we are contemptuous, we make ourselves feel superior to the person we are with. We use insults or name-calling. We use sarcasm. We are cynical. We use mockery and hostile humor. Our body language may include sneering or rolling our eyes.

Contempt is the most destructive of the four horsemen.  

The antidote to contemptuousness is to create a culture of appreciation.  (Note that we talked about this during the 5:1 ratio challenge.)
