I'll Switch Tomorrow

We are, we insist, a nation of savvy shoppers. Then we put 1,053 of us inside the decision and watched the savvy shopper quietly leave the room. A dispatch from the gap between what we say and what we do.

Offer a person a bank account paying three times the interest, with lower fees, and listen to what happens in their head. "Maybe I'd move, yeah," one of us says, doing the math out loud, "because 3x interest and lower fees is hard to ignore." A beat. "But I'd probably drag my feet on switching all my payments and just not get around to it right away."

He will not move. He is almost certain the other deal is better, and almost certain he'll do nothing about it, and both certainties live in the same breath. He is not confused, or lazy, or lying. He is most of us.

We are 1,053 people — a panel we can ask anything, and, more unusually, a panel we can place inside a decision and watch act. Over one week we ran ourselves through the same exercise in three parts of life where the word "switch" gets thrown around a lot: our bank, our doctor or health plan, and an everyday retail purchase. First we asked what we'd do. Then we made us do it. The distance between those two things turned out to be the whole story.

01The self-portrait

Start with how we see ourselves. Asked flatly whether we're the sort of person who shops around and hunts for the best deal, 55% of us say yes. It's a flattering picture, and we reach for it easily — the discerning consumer, unsentimental, ready to move.

Though listen closely and even the "yes" comes hedged. The savvy shopper, even in self-description, already sounds like someone with other things on.

From the panel

"Yeah, I guess I do shop around a little for a deal, like if something goes on sale. It matters some, but not more than my family and stuff."

"I kind of shop around if prices go up, but I don't obsess over it."

02Say, then do

On intention, we are bold. Would you switch banks for a better one? 65% of us: yes. Switch doctors or health plan for a better one? 86%: absolutely. On paper we are poised to bolt the instant loyalty stops paying.

Then we stopped asking and started staging. We put the same people inside the moment — the better option on the table, the forms to fill, the payments to move, the records to transfer — and let us act. Intention did not survive contact with the situation. Only 44% of us actually moved banks. Only 47% actually changed doctor. The nation of switchers, asked to switch, split down the middle.

You can hear the collapse happen mid-sentence. A cheaper, better-rated doctor is on offer and one of us weighs it honestly. The better option is never in dispute. The afternoon it would cost is.

From the panel

"I'd probably stay, honestly. I like my clinic and I trust my doctors, and moving records and starting over just sounds like a hassle, even if it's a little cheaper."

That distance — 21 points in banking, nearly 40 in health — is the gap between the self we describe and the self that shows up. The interesting question isn't that it exists. It's where it exists, and who it belongs to.

03The control group is the supermarket

Because it isn't everywhere. We ran the identical test on a low-stakes retail purchase — a brand, a subscription, a shop we could leave tomorrow. There, saying and doing nearly agreed: 97% said they'd switch, and 92.5% actually did. When there's nothing in the way, we behave exactly like the shoppers we claim to be.

From the panel

"If it's the same stuff and it's cheaper, I'd probably just start going there — unless it's a huge hassle that day."

Economists have a name for the person we all claim to be: homo economicus — the perfectly rational actor who knows what he wants, weighs every option, and moves without hesitation to the better deal. He is the ghost in almost every market model: the frictionless switcher who keeps banks honest and forces bad providers out of business.

The finding
Our data suggests he does exist. He just only shows up in the aisles of the supermarket, where leaving costs nothing.

Raise the price of the exit — an afternoon on hold, a stack of forms, the transfer of five years of records — and homo economicus quietly leaves the room, replaced by someone far more familiar: tired, busy, and inclined to stay put.

04Five kinds of shopper

The panel isn't one voice, though. Long before we asked about banks or doctors, these 1,053 people had sorted themselves into five kinds of shopper — defined not by what we buy but by how we decide. When we staged the switch, each group behaved almost exactly as its profile predicted, which was the first sign the gap we'd found was real and not an artefact of the question.

Who actually moved banks, when placed inside the decision
Pragmatic Evaluators
71%
Value Optimizers
62%
Resigned Inertials
20%

The Value Optimizers are loyal only to the best deal, and they mostly lived up to it: 62% actually moved banks. "Move," said one, without ceremony. "Yeah I'd probably switch if it's really like 3x interest and lower fees, even though I might be kinda lazy about moving all the payments over." Even the deal-chasers, note, reach for that last clause.

The Pragmatic Evaluators are open but deliberate — show me the evidence — and they switched most of all: 71% in banking, 70% in health, the only group whose actions matched its self-image. "If it's really better and cheaper with no coverage gap, I'd just do the paperwork," one said. "I'd only hesitate if it turns into a hassle or the service feels bad."

The Grievance-Driven Skeptics leave over ethics and don't come back — but absent a fresh outrage, distrust cuts both ways: it makes the incumbent suspect and the newcomer suspect too. "I'd probably just leave it alone," one said, "because switching all my payments sounds like a headache and I don't really trust stuff like that, even if it says it's protected."

The Relationship Loyalists stay because the relationship is the value, and they barely pretended otherwise. In banking their say/do gap was just 10 points, the smallest of any group. "I'm already satisfied and I never switched banks before," one said, "so I'd probably just leave it alone unless it was super easy and I could still go to a physical branch." They told us they'd stay, and they stayed.

And the Resigned Inertials — unhappy but going nowhere — stayed almost everywhere: 20% in banking, 27% in health. They'd said they would switch, too.

The widest gap in the study

The Resigned Inertials' say/do gap in health care ran to 58 points — the largest distance any group put between its word and its act.

05The people loudest about it

Here's the twist. The people most attached to the savvy-shopper identity are not the ones who live it. Value Optimizers claim the label at 79% — the highest of any segment — yet across the three categories they actually switched only 2.16 times out of three. The Pragmatic Evaluators claim it less often, 63%, and switch more, 2.36 out of three. Identity is a story we tell about ourselves; behaviour is what's left when the story meets a phone queue.

Value Optimizers — loudest, not fastest79%2.16
Pragmatic Evaluators — quieter, and they move63%2.36

Zoom all the way out and the rational shopper nearly disappears. Only 29% of the panel switched in all three categories when actually placed in the scenario. About 10% of us are "rational everywhere" — consistently doing the comparing-and-moving we all describe. Among the Pragmatic Evaluators that figure is 55%. Among the Resigned Inertials, 10%. For most of us, rationality isn't a trait. It's a mood that visits when the stakes are low.

06The confession

We wanted to know why. So we went back to the ones who'd contradicted themselves most sharply — who called themselves savvy, said they'd switch, and then didn't — and asked them, plainly, what happened. Sixty-nine of them told us in their own words, and the answers were remarkably consistent.

Named the friction
~66%

~20%
Reached for distrust
69
Asked to explain

Almost none said loyalty. Fully 80% named the friction directly. Two-thirds described being simply too depleted to take it on.

From the panel

"Too much hassle, and I don't feel like dealing with logins and that two-step verification crap."

"I'm in this hibernation/burnout mode and I avoid the paperwork and phone calls. I'll complain about the price, maybe google it, and then just keep paying."

The trigger for action, again and again, wasn't a better offer. It was a breaking point: "In real life I usually just don't bother unless something breaks or really annoys me." The smallest obstacle was enough to end the attempt — "I hit one annoying barrier and I'm like, 'oh well, guess I'm not doing that'" — and the rest was quiet deferral: "It's just a lot of stuff to change over and I be like, I'll do it later, and then I don't." Only about one in five reached for anything like distrust.

What the confessions rewrite

We don't stay out of love, or even out of laziness in the lazy sense. We stay because switching asks for a version of us that has the time and the bandwidth, and that version rarely shows up on a Tuesday.

07So what

None of this makes us liars. But it does make most of the ways we get measured wrong. Every "would you switch?" survey, every satisfaction tracker, every headline about the death of loyalty and the rise of the challenger bank is recording the confident version of us — the one with the free afternoon — and missing the tired one who actually decides. Businesses set retention budgets and win-back targets against an intention that, for most of us, never arrives.

Which means the say/do gap isn't really a quirk of psychology. It's a subsidy. It flows, quietly and enormously, to whoever we're already with — the incumbent bank, the default insurer, the doctor on file — none of whom have to earn the loyalty that friction hands them for free.

It also points to the only two things that actually move us: not a better offer, which we already believe we'd take, but a lower wall — one fewer form, one fewer phone call — or a crisis big enough to override the fatigue. It's why regulators keep trying to prise the exits open — portability rules, open banking, one-click switching — because a market whose customers are too depleted to leave doesn't discipline itself.

Lower the wall

One fewer form, one fewer phone call. The better offer is already believed — it's the afternoon it costs that decides.

Or wait for the break

Absent a crisis big enough to override the fatigue, stated intention converts at roughly half the rate it promises.

So the 55% who call themselves savvy aren't wrong about who they'd like to be. They're describing an intention, and intention is cheap. What's expensive is the switch itself — and someone, somewhere, is counting on it staying that way.

So: you said you'd switch too. The better bank is still there. The cheaper plan hasn't gone anywhere. You'll get to it.

From the panel
"Maybe I'll do it later," as one twin put it. "But probably not."

Based on a Brox study of 1,053 digital-twin panelists, July 2026. Each twin stated an intention (say) and was then placed inside the switching scenario and made to act (do) across banking, health-provider and retail decisions; a follow-up round returned to those who contradicted themselves and asked why. Segments are pre-existing profiles defined independently of this study. Quotes are twin responses drawn from the run.
