new media challenges

 In all this talk about political developments across the world, why is the topic of adaptation to new media so seldom mentioned. In the 1930's the new media was radio. Now the new media is the internet. History is repeating itself in a new form, although sadly this time lots of the players have nuclear weapons.

Healing Narratives

I keep hearing media whining about "polarization", and in many cases (certainly with election ads) focusing on "who is the bad guy" (with or without evidence), when the long established and standard solution is to: 

  (a) focus on problems that most agree on, and 

  (b) find ways to address them by trial and error. 

This has not only been humanity's superpower over the past 70,000 years, but it is also how life has evolved and nurtured layers of complexity from the beginning i.e. via the cycle of "vary then select".

A superpower weakness!

 Humanity's superpower is our ability to be moved to action by one another's stories. However, when new modes of communication emerge (like radio or the internet) problems of mis-motivation against one another sometimes arise. What instances of this have you noticed?
