With his emphasis on rationality, Jürgen Habermas does not see any merit of humor for deliberation, since it leads only to confusion. It was Sammy Basu who most forcefully has argued that humor can have a positive effect on deliberation serving as social lubricant and breaking ice. An illustration of humor favoring deliberation comes from Srebrenica, where one of the discussion groups was despairing about the wild pigs that come down from the mountains causing severe damage in the yards. One of the Serbs lightens up the atmosphere saying that pigs also want to learn a little culture here. Another Serb picks up on this humor with the remark that where we live is also wilderness, so for the pigs it is all the same. Both speakers get great laughters. They were able to laugh at themselves and the lack of culture in Srebrenica. There is often a fine line between humor and sarcasm; with humor one laughs with others, with sarcasm down at others. In one of the Brazilian favelas a teenager brought the discussion down to a low level of deliberation, when she mocked in a sacastic way a police officer that he took a leisurely walk rather than to do his job.
