Book Review: Connected by Nicholas A. Christakis, MD, PhD and James H. Fowler, PhD
Connected has had a lot of positive press, and the premise is rather provocative, so my work book club chose this for the January reading which we discussed this week. It doesn’t disappoint.
Christakis and Fowler put forth a tidal wave of studies and analytics showing that there really is no such thing as independent free will, that everything we do, from how much we make to how we vote politically, is influenced by the people up to three degrees from us. (So for me, dear readers, that would be all your friend’s friends.) Reading this book felt like taking an anti-Ayn Rand pill. The poster child for the libertarians, Rand’s whole objectivism philosophy is based on the idea of selfishness and individual choice. Christakis and Fowler put forth the idea that try as much as you like, if you are a human being (and certain animals) you can’t help but be influenced by your social network. He’s the best argument I’ve ever read to debunk Ayn Rand and that’s really saying something.
Christakis and Fowler then take a nice little stroll into the specifics, citing examples and studies. Love and dating? Check. Disease and illness including obesity? Check. Your wealth and income profile? Check. Your political affiliation? Check. It seems like no facet of modern life is immune to the effect of these people 3 steps removed from you, who most likely, you’ve never met.
Overarching the topic specific examples are a couple of themes. The first is that kindness and compassion beget kindness and compassion, and vice versa. The examples he cites regarding transplant patients is particularly heart-warming. Another is that we are genetically wired to be social beings receptive to group norms; cooperation was key to our early hominoid development. He even cites experiments that show that we might be able to predict your position in a social network based on genetics!
The book also had some really interesting facts. For example, women are the key to spreading behavior through a network, since they usually are the people that maintain ties. It was also very interesting to read about AIDs being spread in Africa. He cites evidence that the spread of HIV isn’t a hub and spoke model with sex workers at the core, but rather a fundamental difference in African social networks vs. those in the U.S. This was fascinating.
Of course the health implications were most immediate for our group. Here I quote the book: “Our health also depends quite literally on the biology, choices, and actions of those around us.” Social network information can really change the discourse on public health – and we are just beginning to understand how.
A review of the book isn’t complete without a shout out to social networking on-line. The main take-aways here are that modern technological devices have made us more susceptible to panic and more likely to organize against a perceived offense. The first is discussed better in other finance books and nothing here was groundbreaking. The second was more interesting; there was a story about a builder in Canada who swore they would never build another networked community after the first one he built were able to organize a neighborhood association in record time to complain against shoddy workmanship. At the end of the day though, the authors agree, social networking is no replacement for relationships in real life.
All in all an interesting read on a burgeoning topic. It will be interesting to visit this topic again in 10 years or so and see what other breakthroughs are uncovered.
