150

“Dunbar’s Number” emerged more than 10 years ago.  It postulates that humans can only cognitively keep track of about 150 contacts in their community or sphere. 

This is a useful number for office spaces, residential communities, marketers, and perhaps wedding planners.

This output was being presented and discussed 10 years ago, lamenting the increased use of screens and growing ‘followers’ for socialising. 

The research also identified the importance of human touch, pointing out that while screen-based communication serves to ‘prevent the decay’ of an established relationship, it is still crucial to meet up at the pub to fully appreciate it.
