Systems Thinking + The Obama Code

What if the President of United States was a systems thinker?  What if he talked about systems — rather than fragments — as the context for his decisions and policy making? What if he showed us that it is possible to stop operating from crisis to crisis, and to act in a more integrated, less reactive way?

This seems like a bunch of far-out ideas, right?

Not according to George Lakoff , professor of cognitive linguistics at U.C. Berkeley.  In The Obama Code, Lakoff describes seven “crucial intellectual moves” that are behind Obama’s code of conduct.  One of these seven moves (number six on the list) is Obama’s understanding of “systemic causation” versus “direct causation.” 

 Now, if you’re not a linguist, what does systemic causation mean, and how is it different than direct causation?

Let’s look at the difference by looking at the story of Laurie (hang in here with me, we’ll get back to Obama): 

Laurie was in trouble. Her new consulting job was great for the first few months but now projects were piling up. She was missing deadlines, her e-mail box was full and every voice mail was marked “urgent.”   At home, she found herself distracted and testy, snapping at the kids for no particular reason.

At a lunch meeting one day, while her colleagues engaged in a staccato thumb war on their PDA’s, Laurie waited impatiently for her laptop to boot up.  The next week, she found herself wandering the halls, wasting precious time and unable to find her colleagues for the weekly lunch meeting.  She found out later that the meeting had been moved; everyone else had picked up the message on their PDAs.   When her boss teased her about joining the 21st century, she decided something had to change, and fast.

That evening, she got on-line and bought the fastest PDA she could find.  Within 24 hours, she had it loaded up with all of her contact information and “to do” lists.  Now, when she wanted to contact a client or send a document, she could do it all from one pocket-sized machine.

For a few months, Laurie felt like she was getting on top of her work. She found herself firing off e-mails at all times of day and in all kinds of locations:  at the breakfast table, at soccer games, in the grocery store, even while her kids were taking a bath. It became a game to see how quickly she could respond to clients’ requests.  Laurie was hooked.

As her response time began to improve, her clients settled down and her anxiety began to wane.  As the pressure decreased and her productivity went up, she did what most people would do: she began to take on more work.  After a few months, Laurie started to notice she was drinking more coffee to keep up the pace, and that anxious feeling started to creep in again. As she took on more work, the pressure increased and her ability to get it all done, even with the PDA, began to decrease.  In the end, she was more tired and more anxious than she was before she purchased the PDA. 

What happened?  Laurie did what most of us would do when faced with a problem:  she found a way to make the problem go away.  Let’s take a look at the way Laurie “solved” her problem: 

        PROBLEM (Lack of productivity) —> SOLUTION (Time-saving device).

Laurie solved her problem by finding a clear and definite way out, taking a straight line from the problem to the solution. A solves B, end of story.  This is what Lakoff calls direct causationAfter implementing “the solution” Laurie thinks she solved the problem, yet her solution only makes the original problem worse.

How did Laurie get into this position?  Just like Laurie, most of us have been conditioned to think in terms of straight lines.  A fire breaks out in the neighborhood, quick, call the fire department.  A teacher is out sick, call in a substitute.  Step on a rusty nail, call the doctor and get a tetnus shot. The school roof is leaking, fix it. The market is down – sell (or buy).  In these situations, we react, in the moment, to a problem that is well-defined. We go back to these straight line – A —> B – solutions because the problem usually goes away.   

Yet many of the challenges we encounter are not made up of simple straight lines but patterns of interaction that better resemble loops, webs and networks.  What’s more, many of life’s challenges are dynamic, changing over time, not static, single events we can address individually. Many people learn this when they become parents or managers. A congratulatory pat on the back to one child can send a sibling into a green-eyed tizzy. As a manager, you learn that a golf outing billed as a team building day becomes a “wicked mess” when members of your team don’t play golf. Rather than straight lines, these messy real-life challenges are more like systems. They’re made up of elements that interact and affect one another, often in ways we cannot see.

This is what Lakoff calls systemic causation. Understanding systemic causation means we see causality in terms of interrelationships, rather than fragments, and multiple causes and effects rather than isolated events.  If Laurie were to look at her situation as a system, it might be drawn like this:

Now, of course, you don’t have to draw these systems maps when every time you find your self smack in the middle of what Russell Ackoff calls a “wicked mess”, but sometimes, it can really help. 

When you make the system visible, you can then think more objectively about what link to break, or what additional loop you might add.  For instance, looking at the above map, Laurie might see that the leverage lies in monitoring what she deems as “an acceptable workload.”  Just because she can take on more work, doesn’t mean she should. 

Laurie may also review her goals, however implicit they may be. She may decide her goal is to be successful and to have a happy, low-stress home life and so may find it acceptable not to take on additional client work.  If her goal is to be the top consultant in the firm, and maintaining a steady workload is not an option, she may choose another systemic strategy.  She may add a loop, in this case, a balancing loop.  In Laurie’s case, she might add a “relaxation” loop, to manage or lower the stress she feels from an increased workload.  In this balancing loop, as Laurie’s anxiety goes up, she manages it with some activity, such as meditation, yoga or walking.

Back to Obama:  the bottom line here is that by taking a systemic view —  of climate change, of our schools, of the economy, of global conflicts — Obama is more likely to get our nation off the problem solving treadmill, where one “solution” only leads to a new problem, and onto more sustainable, more integrated strategies for change.  

 

 

 

Thinking Like a Bathtub + Climate Change

Everyone knows how a bathtub works, right?  If water flows into the tub faster than it flows out, what happens to the amount of water in the tub?   If you said the water level rises, you’re right.  And if the water flows out of the tub faster than it flows in, what happens?

(Right again. The water level lowers).

Now you know how to think like a bathtub.

So let’s see how you would you answer this question (posed today by New York Times science writer, Andrew Revkin):

         “When is the atmosphere like a bathtub?”

If you’re thinking that the atmosphere accumulates carbon dioxide and other greenhouse gases the way a bathtub accumulates water, you are right once more.  Most climatologists agree that humans are putting greenhouse gases into the atmosphere at almost twice the rate that natural processes (such as oceans and other carbon sinks) can remove them. slide1

For a fuller explanation of these bathtub dynamics, see Revkin’s blog, Dot Earth, or the Sterman & Booth Sweeney article,  “Cloudy Skies:  Assessing Public Understanding of Global Warming.  (By the way, if you don’t know the work of MIT professor John Sterman, you should! If you watch the video of Sterman on the Revkin post, go to minute 18 for the best part).

Here’s the rub:  how well do we understand accumulations and flows, also known as stocks and flows? Not well according to some research studies.   This isn’t surprising really.   If you think about it, where did you learn to think about stocks and flows?

You may not have learned about stocks and flows in school, but anyone who has taken a bath, has opened a bank account or has clutter in their home, intuitively understands stock-flow structures.  You can imagine your bank account balance as a kind of bathtub—the money in it just keeps getting higher and higher (as long as you don’t make any withdrawals, of course!). So, the balance is something that accumulates. On the other hand, the paying of interest on the account is more like a faucet that flows faster the higher your balance gets.  Systems dynamicists would describe your account balance as a stock and your interest payments as a flow. Each of them influences the other.  Essentially, an amount of something—trees, fish, people, goods, clutter—is a stock. The rate at which a stock changes, going up or down, is its flow.

At this point, you may be muttering to yourself, SO WHAT?!  Why do I need to know about stocks and flows?

Stocks and flows create many of the most perplexing dynamics we encounter because stocks tend to accumulate, and we often don’t see that accumulation.  Studies of the pesticide DDT, for example, have shown while DDT evaporates from the surface of plants and buildings over six months, it remains in the tissue of fish for up to 50 years.  The amount of DDT in fish tissue is a stock with very slow outflow.

When we understand stocks and flows, we understand that a deficit (the rate at which a country borrows money) is a flow and the national debt is a stock.  We understand, as well, that taking the national deficit down to zero doesn’t mean we get rid of the debt.  We also understand that proposals to “slow the rate of growth of carbon dioxide emissions” will continue to increase the stock of carbon dioxide and other greenhouse gases in the atmosphere, if the rate at which carbon dioxide flowing into the atmosphere continues to be greater than the rate at which it is draining out.

And a big one for me, we understand that we can address clutter (a stock) by turning down the inflow (the rate at which we buy stuff), or turning up the outflow (the rate at which we recycle, give away/throw away, put stuff on ebay, etc.)
