First, full disclosure: I'm a business partner with Roy Williams and a friend of Mike Drew's. If you want to take my review with a grain of salt because of this, I understand. But I think the intriguing and compelling ideas presented in this book are able to speak for themselves, quite apart from whatever my personal endorsement might bring to the table.
Here's what I mean by that: just every 80 years we have a massive big time civic crises (usually involving wars). So you can think of the revolutionary war, civil war, and WWII. All pretty much 80 years apart, give or take a few years. In between you have spiritual awakenings, which are also 80 years apart, making each "awakening" about 40 years out from a civic crises. Of course, spiritual awakenings last a bit longer than wars, but the first "Great Awakening" started in 1720 and ended in 1750, with a mid period 1735. The second Great Awakening starts in 1800 and lasts till 1840, with a midpoint at 1820. The third Great Awakening starts early, but ends about on time, going from 1850-1910 and making the midpoint at 1880. And then there's the 60's, aka "The Fourth Awakening" happening 80 years after 1880. Civic Crises and Spiritual Awakenings occur like clockwork, alternating every 40 years.
Now, if you're a critical thinker, you're probably thinking to yourself that that's an interesting pattern/theory, but there are some holes and questions, right? How do you know I'm not cherry-picking events to fit the pattern and leaving out events that don't fit? And, what if this pattern does really exist -- so what?
In Pendulum, Roy and Michael Drew did the hard research to prove that the pattern is real, that it still exists even when the data is exhaustive and the researcher sets out to disprove the pattern, and that the pattern goes back thousands of years. More importantly, they show the WHY behind the cycles. Every 40 years society moves from an Idealist to a Civic mindset, and that 2003 represented one of those shifts, away from Idealist and into Civic, just as 1963 marked the beginning of a shift away from Civic and into the Idealist "Sixties" era "Me Generation." This is why "being cool" morphed into "Keeping it real." Why the very slick James Bond got Jason Bourned into a far more flawed and vulnerable human being, and so on.
Obviously, major societal shifts like this are pretty important for anyone who considers herself a leader, communicator, persuader, or business person. If you fit into one of those categories, I strongly recommend the book. And regardless of how you classify yourself, if you want to learrn more about this stuff in a fairly quick, enjoyable read -- and especially if you want to know how this pattern will affect you and the people you care about in the coming years -- you should get this book.
It's a book of big ideas and actionable insight in a an engaging, enjoyable package. What more could you want?
