Why is it so hard to make lasting changes in our companies, in our communities, and in our own lives?
The primary obstacle is a conflict that’s built into our brains, say Chip and Dan Heath, authors of the critically acclaimed bestseller Made to Stick. Psychologists have discovered that our minds are ruled by two different systems—the rational mind and the emotional mind—that compete for control. The rational mind wants a great beach body; the emotional mind wants that Oreo cookie. The rational mind wants to change something at work; the emotional mind loves the comfort of the existing routine. This tension can doom a change effort—but if it is overcome, change can come quickly.
In Switch, the Heaths show how everyday people—employees and managers, parents and nurses—have united both minds and, as a result, achieved dramatic results:
-The lowly medical interns who managed to defeat an entrenched, decades-old medical practice that was endangering patients.
-The home-organizing guru who developed a simple technique for overcoming the dread of housekeeping.
-The manager who transformed a lackadaisical customer-support team into service zealots by removing a standard tool of customer service
In a compelling, story-driven narrative, the Heaths bring together decades of counterintuitive research in psychology, sociology, and other fields to shed new light on how we can effect transformative change. Switch shows that successful changes follow a pattern, a pattern you can use to make the changes that matter to you, whether your interest is in changing the world or changing your waistline.

The Three Surprises About Change
1.
One Saturday in 2000, some unsuspecting moviegoers showed up at a suburban theater in Chicago to catch a 1:05 P.M matinee of Mel Gibson's action flick Payback. They were handed a soft drink and a free bucket of popcorn and asked to stick around after the movie to answer a few questions about the concession stand. These movie fans had unwittingly entered a study of irrational eating behavior.1
There was something unusual about the popcorn they received. It was wretched. In fact, it had been carefully engineered to be wretched. It'd been popped five days earlier and was so stale that it squeaked when you ate it. One moviegoer later compared it to Styrofoam packing peanuts, and two others, forgetting that they'd received the popcorn for free, demanded their money back.
Some of them got their free popcorn in a medium-sized bucket, and others got a large bucket--the sort of huge tub that looks like it might once have been an above-ground swimming pool. Everybody got their own individual bucket so there'd be no need to share. The researchers responsible for the study were interested in a simple question: Would the people with bigger buckets eat more?
Both buckets were designed to be so big that no one could finish their portion. So the actual research question was a bit more specific: Would somebody with a larger inexhaustible supply of popcorn eat more than someone with a smaller inexhaustible supply?
The sneaky researchers weighed the buckets before and after the movie, so they were able to measure precisely how much popcorn each person ate. The results were stunning: People with the large buckets ate 53 percent more popcorn than people with the medium size. That's the equivalent of 173 more calories and approximately 21 extra hand-dips into the bucket.2
The author of the study, Brian Wansink, runs the Food and Brand Lab at Cornell University and he described the results in his book Mindless Eating: "We've run other popcorn studies, and the results were always the same, however we tweaked the details. It didn't matter if our moviegoers were in Pennsylvania, Illinois, or Iowa, and it didn't matter what kind of movie was showing; all of our popcorn studies led to the same conclusion. People eat more when you give them a bigger container. Period."
No other theory explains the behavior. These people weren't eating for pleasure. (The popcorn was so stale it squeaked!) They weren't driven by a desire to "finish their portion." (Both buckets were too big to finish.) It didn't matter whether they were hungry or full. The equation is unyielding: Bigger container = more eating.
Best of all, people refused to believe the results. After the movie, the researchers told the moviegoers about the two bucket sizes and the findings of their past research. The researchers asked, do you think you ate more because of the larger size? The vast majority scoffed at the idea, saying things like, "Things like that don't trick me," or "I'm pretty good at knowing when I'm full."
Whoops.

Imagine that someone showed you the data from this study but didn't mention the bucket sizes. On your data summary, you'd see how much popcorn each person ate. You could quickly scan the results and see the differences--some people ate a little bit of popcorn, some ate a lot, and some seem determined to test the physical limits of the human stomach. Armed with a data set like that, you would have found it easy to jump to conclusions. Some people in the world are Reasonable Snackers and others are Big Gluttons.
A public health expert, studying that data alongside you, would likely get very worried about the Gluttons. We need to motivate these people to adopt healthier snacking behaviors! Let's find ways to show them the health hazards of eating so much! And maybe we should approach state legislators about a Big Bucket Ban!
