Just how individualistic and independent are we? Far less than we think according to neuroscientist, Jonah Lehrer.
In an article in Wired, Jonah uses sharp graphics to paint before and after snapshots of social networks. Each diagram sheds light on the profound influence people have on the happiness, obesity and smoking habits of friends and relations. We extol the virtue of personal responsibility, but peer pressure is a far stronger force:
Having an obese spouse raised the risk of becoming obese by 37 percent. If a friend became obese, the risk skyrocketed by 171 percent. Lean individuals surrounded by obesity were rare.
Subcultures and Self-Segregation
Walk into any coffee shop, bar or church and you’ll find self-segregation. Like-minded people hang out together. No surprise there. What is surprising, however, is the subconscious influence that arises, and keeps arising, after your single, conscious decision to join. You don’t realize, let alone question, the extra calories, cigarettes, depression or happiness that originates from ongoing exposure to any particular social network.
Free Will Lost?
Free will is a philosophical can of worms that I’ll save for another entry, or treatise. Putting the question of free will into more immediate focus, what do these findings mean for commercial communication?
Malcolm Gladwell’s Tipping Point examines the role that people play as nodes in a social network. But there’s a big difference between deciding to see a movie or buy sneakers because of a friend”s influence and changing the course of your life, health and happiness without even knowing that you’ve made a decision. I have a feeling that this research is just the tip of the tipping point.
