Gossip

Gossip take up to 2/3 of converastion time. It's suggested role is to defend aggainst free riders (parazite), or basicly against ingustice.

Gossip, I think, is dervied from the need to talk with others and look at problems from other perspective. In people with low self-esteem and FFFF or system 1 decison making system, the gossip is used to get reasurance that we are OK, and the others are bad. Therefore when there is a society with high precentage of system 1/FFFF decision system (conservatives), we may observe a lot of smear campains. In social wars, partisans may try to harm other by smear campain, carried by gossip.
