How Humans Are Like Fungi
Nicholas A. Christakis, M.D., M.P.H., Ph.D., is an internist and social scientist who conducts research on social factors that affect health, health care, and longevity. He is a Professor of Sociology in the Department of Sociology in the Harvard Faculty of Arts and Sciences; Professor of Medical Sociology in the Department of Health Care Policy at Harvard Medical School; and Professor of Medicine in the Department of Medicine at Harvard Medical School.
Dr. Christakis' current work is principally concerned with health and social networks, and specifically with how ill health, disability, health behavior, health care, and death in one person can influence the same phenomena in a person's social network. Most recently, Dr. Christakis has been exploring the joint genetic and socio-environmental determinants of the formation and operation of human social networks. His 2009 book, co-authored with James H. Fowler and published by Little, Brown and Company, is called "Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives."

Nicholas\r\n Christakis: I’m a professor of medicine and professor of medical \r\nsociology at Harvard Medical School and a professor of sociology in the \r\nFaculty of Arts and Sciences and I do what I would call network science,\r\n so I, for the last ten years, have been studying how and why human \r\nbeings come to be embedded in social networks. Not the kind of online \r\nkind that people might think about all the time nowadays, but the kind \r\nof ancient kind that we have formed for hundreds of thousands of years. \r\nAnd I study how we humans come to form these very elaborate networks and\r\n what these networks come to mean for our lives, and the sort of the \r\nfield as it were of medical sociology is concerned with all sorts of \r\nphenomena, social processes and social phenomena that influence health \r\nand health care. But I’m focused primarily on I would say a subset of \r\nthat or not a subset, but a different field. Let’s say network science.
Question:\r\n What kind of research went into your book “Connected”?
Nicholas\r\n Christakis: We have done work on the social, psychological, \r\nmathematical and biological rules that govern how human beings come to \r\nform social networks—the structure of networks—and then we’ve also \r\nexamined the kind of social and psychological rules or attributes of how\r\n social networks function. So how do we form social networks and how do \r\nthey affect our lives, and it’s what we would consider to be the anatomy\r\n and the physiology of a kind of human superorganism. In a very \r\nfundamental way we are like ants or actually kind of like fungi too, \r\nwhere individual human beings assemble themselves into these elaborate \r\ncomplex structures and we’re… James Fowler and I, my coauthor, are \r\ndeeply concerned with how and why we form these structures and what they\r\n mean for our lives. So in the book we present about… We talk a lot \r\nabout our own research, but we also pull in the research of many other \r\nscientists who have been looking at a variety of phenomena, and we talk \r\nabout the role of social networks in human emotions. We talk about the \r\nrole of social networks in human romantic and sexual behavior, in \r\nhealth, in politics and in economics, and then we also talk a little bit\r\n about the genetics of human social networks and the sort of modern \r\nonline variety of social interactions, and then we close with an \r\nargument in the book about why we form social networks and what in a \r\nvery deep sense they mean for our lives.

The social networks we form add up to a giant "human superorganism."

We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Infographics show the classes and anxieties in the supposedly classless U.S. economy.
For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
