Two Types of Social Grooming discovered in Primitive and Modern Communication Data-Sets

Social networking sites (SNS) provide innovative social bonding methods known as social grooming. These have drastically decreased time and distance constraints of social grooming. Here we show two type social grooming (elaborate social grooming and lightweight social grooming) discovered in a model constructed by thirty communication data-sets including face to face, SNS, mobile phones, and Chacma baboons. This demarcation is caused by a trade-off between the number and strength of social relationships on social grooming. The trade-off of elaborate social grooming is weaker than the trade-off of lightweight social grooming. On the other hand, the cost of elaborate methods is higher than lightweight methods. This model conar X iv :1 70 7. 08 51 7v 1 [ cs .S I] 2 6 Ju l 2 01 7 nects micro-social grooming behaviour and macro-social structures with these trade-offs. People tend to use elaborate social grooming to reinforce close relationships and construct deep limited societies (e.g. face to face and Chacma baboons). This seems to be apriori. On the other hand, people tend to use lightweight social grooming to maintain many weak social relationships and construct expanded shallow societies (e.g. SNS). Humans recently have obtained this method. Humans with lightweight methods who live in significantly complex societies use various social grooming to effectively construct social relationships. Elaborate social grooming is for getting cooperation from close relationships. Lightweight social grooming is for getting information from many weak relationships.
