Less connected social networks solve complex problems better : Go ahead, have a dream

This is is a less-connected network, with 88 nodes.

This is a well-connected network, 88 notes, with 172 links.

 Here’s what happens when the well-connected network works to provide a solution to a complex problem.

Here’s what happens when the less-connected network does the same work, given the same amount of time.

Here’s what happens when the less connected network gets extra time.

The less connected network takes more time, but comes up with a better solution.

At the extremes (extremely un-connected, and extremely-well connected) networks do poorly.

What does this mean and how did I introduce it when talking about social media in health care recently?

(See Presentation: Why be Social (Media) – Kaiser Permanente Colorado – “Destination Leadership” | Ted Eytan, MD)

  • Health care can be very insular.
  • People often seek solutions inside the walls and forget to connect in less-well-traveled places to learn.
  • They don’t know what they don’t know.
  • Using social media to talk and not listen doesn’t help this situation. That’s not being social, it’s being antisocial.

This is what it means for me.

As I mentioned in Colorado, people have connected with me online to tell me about wonderful health care experiences, as well as health care experiences that were not so wonderful, or even hurtful. Regina Holliday (@ReginaHolliday) is one amazing example. There are many others.

How do you know how to make things better if you’re only talking to people just like you? 

That’s where social networks come in to help us listen and engage.

We talk about patient engagement all the time, let’s not forget physician/clinician/health professional engagement.


Today is a special day in history. When people tell us to be less passionate about reducing inequality and improving health for all, the words of other misfits come to mind:

  • Go ahead, have a dream.
  • Don’t live someone else’s life
  • The world belongs to optimists, pessimists are bystanders


All computer simulations were run by me. To access the mathematical models and reference behind this example, see Lazer, David and Friedman, Allan, “The network structure of exploration and exploitation” (2007). Computer and Information Science Faculty Publications. Paper 1.
