The Power of Habit

One day in the early 1900s, a prominent American businessman named Claude C. Hopkins was approached by an old friend with an amazing new creation: a minty, frothy toothpaste named “Pepsodent” that, he promised, was going to be huge.

Hopkins, at the time, was one of the nation's most famous advertising executives. He was the ad man who had convinced Americans to buy Schlitz beer by boasting that the company cleaned their bottles “with live steam” (while neglecting to mention that every other company used the same method). He had seduced millions of women into purchasing Palmolive soap by proclaiming that Cleopatra had washed with it, despite the sputtering protests of outraged historians.

But Hopkins' greatest contribution would be helping to create a national toothbrushing habit. Before Pepsodent, almost no Americans brushed their teeth. A decade after Hopkins' advertising campaigns, pollsters found that toothbrushing had become a daily ritual for more than half the population. Everyone from Shirley Temple to Clark Gable eventually bragged about a "Pepsodent smile."

I discovered the story of Claude Hopkins a few years ago while reporting my book, The Power of Habit, which explores the science of habit formation. Today, Hopkins is almost totally forgotten. He shouldn't be. Hopkins was among the first to elucidate principles that even now influence how video games are designed, public health campaigns are managed and that explain why some people effortlessly exercise every morning, while others can't pass a box of doughnuts without automatically grabbing a jelly-filled cruller.

So, how did Hopkins start America brushing?

By taking advantage of a quirk in the neurology of habits. It wouldn't be until almost a century later that medical schools and psychology labs would fully understand why habits exist and how they function. Today, we can create and change habits almost like flipping a switch.

But there are historical outliers who seemed to intuitc or accidentally stumble into - these insights before anyone else. Hopkins created a toothbrushing habit by identifying a simple and obvious cue, delivering a clear reward and —most important —by creating a neurological craving.

And craving, it turns out, is what powers a habit.

All habits—no matter how large or small—have three components, according to neurological studies. There's a cue—a trigger for a particular behavior; a routine, which is the behavior itself; and a reward, which is how your brain decides whether to remember a habit for the future. When Hopkins identified tooth film, he found a cue that had existed for eons. Moreover, the reward that Hopkins was promising was hard to resist. Who doesn’t want a prettier smile? Particularly when all it takes is a quick brush with Pepsodent?


Three weeks after the first Pepsodent ad campaign, demand for the toothpaste exploded. There were so many orders that the company couldn’t keep up. In three years, the product went international. Within a decade, Pepsodent was one of the top sellers around the globe.

“I made for myself a million dollars on Pepsodent,” Hopkins wrote a few years after the product appeared on shelves. The key, he said, was that he had grounded his advertising campaign in two basic rules:

First, find a simple and obvious cue.

Second, clearly define the rewards.

Even today, Hopkins’s rules are a staple of marketing textbooks. They're cited in boardrooms, advertising offices, and business school classrooms.

But that's not the full explanation of why Pepsodent was such a success. There's another rule that even Hopkins, at the time, didn't understand.
