Humans, public relations and the internet

  In PR this means that, with some exceptions, we should aim to belong 
to  a  large  number  of  groups  rather  than  to  broadcast  in  a group  with  a 
large number of online members. At this level the cultural, and critically 
emotional, relationships are  high.  We  have noted elsewhere  in  this  book 
that, online, mass media thinking has its limitations.
  One  of  the  amazing  things  about  people  is  their  ability  to  extend  the 
capability  of  the  body  and  brain  beyond  its  biological  (physiological) 
capacity. We can travel further and faster on a bicycle, car or plane because 
we have extended our physiology with knowledge. We have extended our 
brain with devices like pocket calculators, digital cameras and computers; 
that is, we use our brain to make machines do extramural work. We have 
also  extended  our  memory  with  access  to  Wikipedia  and  the  rest  of  the 
internet.
  We have also limited our physical capabilities because of our civilization. 
Someone born and raised in London is unlikely to have the skills needed to 
survive in the Borneo jungle; we have lost skills and knowledge too.
  Large  brains  confer  an  advantage  when  responding  to  variable,  un-
predictable, and novel ecological demands through enhanced behavioural 
flexibility, learning, and innovation.

  Human have large brains. Be�er than that, humans like novelty. We are 
quick  to  learn  causal  associations  between  co-occurring  environmental 
stimuli. Does this resonate with users of Facebook and MySpace trying out 
and adding new widgets to their accounts? Who has not been distracted 
when  using  search  engines  and  diverted  to  something  that  looked 
‘interesting’ and novel. Using these online facilities, we pander to our ‘large 
brain’ needs.

  Our use of the evolving internet, the social internet, is dependent on many 
services (as Twi�er is to Facebook, mobile phone video is to YouTube and 
adding a hyperlink is to e-mail). It will include achieving even more things 
to facilitate our physical, intellectual and emotional needs and, above all, 
our need to join social groups. We will, in the process forgo once common 
capabilities like typese�ing, shorthand and faxing. The internet is and will 
continue  to  be  a  place  where  we  can  experiment  with  novel  things  and 
find new ways to achieve gratification. In this sense, we can argue that the 
progression from Usenet to Twi�er and beyond is part of human biology.
  As a nerve cell in the human brain is stimulated by new experiences and 
exposure to incoming information from the senses, it grows branches called 
dendrites. With use, you grow branches; without it they are impoverished 
and  you  lose  them.  People  can  even  use  parts  of  the  brain  to  do  novel 
things;  we  have  ‘neuro-plasticity’,  the  capacity  for  changes  that  occur  in 
the organization of  the  brain as a result  of  experience.
13
 This means  that 
our brains can change substantially as a result of practice and experience 
throughout life.

 Furthermore, a specific variant in humans suggests that 
the human brain is still undergoing rapid adaptive evolution.
