On this blog I've often discussed generational cycles starting back in 2004 with this post. If you've read other posts sprinkled through the years, you know that as a culture and society we swing between two major perspectives which influence thought and behavior at an individual and societal level. These two cycles, often illustrated by a pendulum, are the idealistic generation and the civic generation. The last idealistic cycle ran from 1963 to 2003 at which time we tipped into a civic generational mindset.
In Clay Shirky's short TED Talk, he makes a lot of good points but perhaps even unwittingly reveals more evidence that the culture has indeed changed and we are well into the 40-year civic cycle of the generational pendulum.
