There is a peculiar form of gaslighting that occurs when a government agency announces inflation has cooled to a comfortable level and you return from the supermarket having spent more than you ever have on fewer items than you used to buy. The numbers are not fabricated. Your experience is not imaginary. The disconnect is structural, and understanding it reveals something important about how we measure economic reality versus how we live it.

The phenomenon is sometimes called the "inflation perception gap" — the persistent divergence between official price indices and consumer sentiment about prices. But that clinical term obscures a messier truth: the statistics are designed to answer questions that may not be the ones ordinary people are asking.

What the index actually measures

Consumer price indices, the standard tool for tracking inflation in most developed economies, are engineering marvels of statistical abstraction. They track a representative "basket" of goods and services, weighted by how much the average household spends on each category. When the price of televisions falls dramatically — as it has for decades — that decline offsets rising costs elsewhere. When a steak becomes too expensive and consumers switch to chicken, the index adjusts to reflect their new purchasing patterns.

This is called "substitution bias correction," and it makes perfect sense if your goal is measuring the cost of maintaining a constant standard of living. But it also means the index is quietly redefining what that standard includes. The steak you used to eat is no longer part of the calculation. The smaller package of cereal at the same price — a practice economists call "shrinkflation" — may or may not be captured depending on how the statistical agency handles unit pricing.

The result is an index optimized for macroeconomic policy, not for validating your sense that things cost more than they used to.

The frequency problem

There is another, more visceral issue: people encounter prices unevenly. You buy groceries weekly, fill your gas tank regularly, and notice when your rent increases annually. You buy a television once every several years. The prices that dominate your psychological experience of inflation are precisely the categories that have been most volatile — food, fuel, housing — while the categories that have seen genuine deflation, like consumer electronics and apparel, register only intermittently.

Research on inflation expectations consistently finds that consumers weight frequently purchased items more heavily than their actual budget share would suggest. This is not irrational. It is how memory works. The price of eggs is salient in a way the price of a laptop is not, even if you spend more annually on electronics.

The housing paradox

Nowhere is the gap between statistical reality and lived experience more acute than in housing. Official inflation measures typically track the cost of shelter through a concept called "owners' equivalent rent" — an estimate of what homeowners would pay to rent their own homes. This smooths out the wild swings of actual real estate markets. It also means that when home prices surge, the effect on measured inflation is muted and delayed.

For anyone trying to buy a first home, or watching their rent consume an ever-larger share of their income, the official statistics can feel like a dispatch from a parallel universe where the housing market is merely "moderately elevated."

Our take

The inflation perception gap is not a bug in human psychology to be corrected through better financial education. It is a feature of measurement systems designed for purposes other than reflecting individual experience. Central bankers need stable, comparable indices to set monetary policy. Households need to know why they feel poorer despite being told the economy is fine. These are different questions, and pretending one number can answer both is the real source of the disconnect. The next time official statistics and your grocery receipt disagree, consider that both might be telling the truth — just not the same truth.
