Strange Contagion: Inside the Surprising Science of Infectious Behaviors and Viral Emotions and What They Tell Us About Ourselves Hardcover – 27 Jun. 2017
Picking up where The Tipping Point leaves off, respected journalist Lee Daniel Kravetz’s Strange Contagion is a provocative look at both the science and lived experience of social contagion.
In 2009, tragedy struck the town of Palo Alto: A student from the local high school had died by suicide by stepping in front of an oncoming train. Grief-stricken, the community mourned what they thought was an isolated loss. Until, a few weeks later, it happened again. And again. And again. In six months, the high school lost five students to suicide at those train tracks.
A recent transplant to the community and a new father himself, Lee Daniel Kravetz’s experience as a science journalist kicked in: what was causing this tragedy? More important, how was it possible that a suicide cluster could develop in a community of concerned, aware, hyper-vigilant adults?
The answer? Social contagion. We all know that ideas, emotions, and actions are communicable—from mirroring someone’s posture to mimicking their speech patterns, we are all driven by unconscious motivations triggered by our environment. But when just the right physiological, psychological, and social factors come together, we get what Kravetz calls a "strange contagion:" a perfect storm of highly common social viruses that, combined, form a highly volatile condition.
Strange Contagion is simultaneously a moving account of one community’s tragedy and a rigorous investigation of social phenomenon, as Kravetz draws on research and insights from experts worldwide to unlock the mystery of how ideas spread, why they take hold, and offer thoughts on our responsibility to one another as citizens of a globally and perpetually connected world.

5.0 out of 5 stars Journey of Hope
5.0 out of 5 stars Excellent book! It's a lovely tribute to the families ...
5.0 out of 5 stars One of the Most Important Books This Year
1.0 out of 5 stars I was very disappointed by this book
As a parent living in Palo Alto within blocks of the incidents, yes it takes some courage to live here. Many of us don't necessarily have a choice to move depending on jobs, taking care of aging parents, or having bought homes years ago. Many of us love it here, and actively choose to stay here, having faith in our community, that we will get through this, and we can stop this. Yes "we're all in this together" but I think a better way of thinking of this is "life is better together." It is a community I'm proud to be part of: caring, compassionate, kind. The suicides don't define us. They never have and they never will. Let the media and the alarmists say what they may.
Yes, the issue is complex. While Kravetz mentions the power of primes, he eventually gives up on the notion that positive primes can mitigate negative ones. I don't agree. He doesn't even address the power of faith or culture. While he focuses on strange contagion in some places and how those places "healed," he doesn't cast an equal eye on places where the contagion doesn't occur. Extending the analogy of viral behavior as he does in his book, we have as much to learn from contagion hot-spots as immunity spots. Why do some areas never see this occur even with similar demographics, affluence, and "success pressure"? He mentions the cemetery but not the proximity of the train tracks. Would this occur in this area if there were no train? Likely not because ease of access has a lot to do with how the contagion can spread more easily in some areas than others.
He does not interview or speak to kids or parents whose children didn't catch the contagion. Maybe - likely - for fear of spreading it. But just as doctors study populations that are resistant to disease, we need to take a deeper look at kids and families who are in higher-risk zones and don't get infected.
Mental illness is barely discussed. It is mentioned as a factor in some of these cases, but does not go into it in depth. But mental illness matters in these cases. Just like a biological virus or bacteria can be more harmful to those susceptible - people can have compromised mental health systems in the same way they can have compromised immune systems. One key will be learning to identify and help those who struggle rather than making a rather huge leap to assume everyone is equally susceptible and no one can possibly know.
Also, there is no look at faith - or other factors - as an inoculating force. In some faiths, there is a strong stance and inoculation against suicide. In some cultures, the stigma against suicide is so strong that it deters it. He doesn't look at any of these factors. There's a lot more to fighting against contagion than support groups and therapists-on-hand. Just as with a virus, you can inoculate and you can strengthen one's "immunity" (resilience) - and they're not "steps" - they are daily actions, like taking your vitamins, getting exercise, getting sleep, taking care of your mental health, having strong support systems, having a strong measure of faith/culture that deters negative behaviors (as with drugs, unprotected sex, violence), having strong healthy relationships that act as deterrents. We do this for our physical health, but our society has not reached the same level of awareness for mental health yet - it's beginning but we are not there yet. But in the same way that we fortify ourselves not to get sick during flu season, I believe we can do as much as we can, and whatever it takes, to mitigate and eradicate this strange contagion.
The author gave up too easily in this book, and I feel, should have known better than to send his concluding message that his own family was driven to move away. Based on his own research on primes and messaging, I wish he had kept that part of the story to himself - it was abrupt and jarring. I understand his personal decision (and it is consistent with the cold sore/preschool decision that his family made at the beginning of the book, so it goes full circle), and you have to do what's best for you, but at the same time, given his own research, it sends a very bleak signal to the rest of the community and the world at large. As a result, I fear this book will do more harm than good. Thankfully, there are people who don't reach the same conclusion. Thankfully, there are those who see a war and sign up to fight on the front lines so the rest of us can be free; there are those who fly into Ebola zones to treat the dying against the odds and not only live to see another day but stemmed the tide of a strange and deadly contagion so the rest of us could live.
Speaking as a person living in this community, as a parent shoulder-to-shoulder, neighbor-to-neighbor with those who lost their children to suicide or have been affected (all of us), this community is strong, it is powerful, it is good, and it is full of hope. We need each other, so we will stay for each other because life is better together.
