The Inertia Default

The Inertia Default

The great enemy of any attempt to change men’s habits is inertia. Civilization is limited by inertia.

—EDWARD L. BERNAYS, Propaganda

IN THE MID-2000S, I INVESTED A SIGNIFICANT PORTION of my net worth into a small restaurant chain. A large investor had bought a controlling stake in the company and managed to turn around the operations, but those changes weren’t yet reflected in the company’s stock price. The CEO said and did all the right things. It was a compelling opportunity, so I went all in.

Over the subsequent years, however, the CEO’s attitude changed. What began as a fair partnership turned into a dictatorship. Like a pot of water coming to boil, the change was slow and hard to notice until, all of a sudden, it was boiling over.

I’d made multiples on the investment and believed in its future, so I was hesitant to exit the position too quickly—but eventually the facts became overwhelming, and I had to sell. After a bit of success, the ego default had taken control of the CEO. Suddenly all partners weren’t exactly equal, one was better than the rest.

Changing my mind took a while. Each transgression by the CEO was minor and easy to explain away. It was only after I’d stepped away from the situation and began viewing it with some perspective that I realized how far the behavior had gone. I was lucky to get out before it became apparent to everyone else—I came awfully close to losing a whole lot of money.

The inertia default pushes us to maintain the status quo. Starting something is hard but so too is stopping something. We resist change even when change is for the best.

The Latin word inertia means literally “inertness”: that is, laziness or idleness. In physics, inertia refers to the resistance of any physical object to a change in its velocity—whether that’s a change in speed or direction. This is a popular way of stating Newton’s first law of motion: a body in motion tends to stay in motion, and a body at rest tends to stay at rest. Objects never change if left alone; they don’t start moving on their own, nor do they stop moving until something acts on them. Long before Newton, René Descartes summarized the same principle: “Each thing, as far as is in its power, always remains in the same state; and that consequently, when it is once moved, it always continues to move.” This physical law maps directly onto human behavior and organizations: once our minds, habits, or strategies are set in a direction, they tend to continue in that direction unless acted upon by some outside force. The result is cognitive inertia—the unthinking tendency to stay on the same path because it is the default, the path of least resistance.

This default keeps us in jobs we hate and in relationships that don’t make us happy, because in both cases we know what to expect and it’s comforting to have our expectations reliably met. It shows up in everyday decisions, like sticking to the same grocery store brand even when a superior option appears on the market. The uncertainty and effort of evaluating something new often feel greater than the possible gain. Companies often overcome this by offering free samples, which lower the risk of trying a new product.

One reason we resist change is that keeping things the same requires almost no effort. This fuels complacency: building momentum takes work, but maintaining it is far easier. Once something becomes “good enough,” we can stop the effort and still get acceptable results, so we stay in our comfort zone long after old techniques or standards have stopped being optimal. Another reason is an asymmetry in how we weigh potential outcomes—negative results hit us harder than positive ones. Doing something different might lead to worse results, making us stand out for the wrong reasons. It often feels safer to remain average than to risk landing below average.

Psychological roots run even deeper. Hierarchy, for example, is a powerful biological instinct. People and groups default to hierarchical structures because they are the path of least resistance, a ready-made order that requires no deliberate design. This deep-seated instinct reinforces inertia in organizations: we keep following established chains of command or processes simply because they are already in place, not because they are the best way.

The economic and business consequences are stark. Investors routinely hold losing stocks too long, not because the prospects are good, but because selling demands a deliberate action that feels like a departure from the default of holding. Companies cling to outdated products or processes until a crisis forces change, squandering resources and missing opportunities. We like to think we’re open-minded and ready to update our beliefs when facts change, but history shows otherwise. When the automobile was introduced, critics dismissed it as a fad, insisting horses and carriages were more reliable. The airplane, radio, television, and the internet all faced similar initial skepticism. In each case, inertia of belief kept most people from imagining a different future until the new invention had already reshaped the world.

The “zone of average” is a particularly dangerous place for inertia to operate. It’s the point where things are working well enough that we feel no urgent need to change. We hope things will magically improve, but they rarely do. A relationship that is “too good to leave and too bad to stay” is a perfect example of the zone of average: if things were much worse, we would act; because they are merely mediocre, we stay and hope. Inertia locks us into a tolerable but unfulfilling present.

Overcoming the inertia default requires identifying the forces that can initiate a change of trajectory—new information, a crisis, leadership intervention, altered incentives, or a compelling vision. Sometimes a small nudge is enough to tip a personal habit, a team’s direction, or an entire system into a new state. Recognizing inertia for what it is—the natural, unthinking pull to keep things as they are—is the first step toward deliberately choosing a better path.
