Death Makes People Shop Differently
Something strange happened to your spending habits in 2020. Maybe you bought a bread maker you used twice, invested in cryptocurrency, or suddenly needed that expensive couch "for working from home." You weren't alone, and you weren't crazy. You were following a psychological script written by plague survivors 700 years ago.
After the Black Death swept through Europe between 1347 and 1351, killing an estimated 30-60% of the population, the survivors did something economists still struggle to explain: they went shopping. Not for necessities — for luxuries. Silk imports to England tripled. Demand for spices, jewelry, and decorative art exploded across the continent. People who had just watched their neighbors die were suddenly buying things their grandparents could never afford.
The pattern has repeated after every major mortality crisis since. Post-WWI America saw the Roaring Twenties spending boom. Post-WWII brought suburban consumption culture. And post-COVID brought us everything from meme stocks to luxury handbags to that sourdough starter industrial complex.
The human brain processes mass death the same way whether it's bubonic plague or a global pandemic. And that processing creates predictable changes in how we think about money, time, and what's worth buying.
Survival Guilt Comes With a Shopping List
When large numbers of people die and you don't, your brain struggles to make sense of the randomness. Medieval chroniclers documented what modern psychologists call survivor guilt, but they also noticed something else: the compulsive need to do something with the windfall.
Because that's what survival often meant in the post-plague economy — a windfall. When a third of the population dies, the survivors inherit their stuff. Wages skyrocketed as labor became scarce. Land values collapsed as demand disappeared. Suddenly, ordinary people had disposable income their ancestors couldn't imagine.
But here's the psychological twist: they couldn't just save it. Surviving records from 14th-century England show that people who lived through the plague were statistically less likely to engage in long-term financial planning. They bought elaborate clothing, threw expensive parties, and commissioned art. They spent like tomorrow might not come, because they had just learned that tomorrow might not come.
This wasn't irrational. It was a rational response to having your assumptions about life's predictability shattered. When you've seen death operate by lottery rules, saving for a retirement that might never happen feels less logical than buying something beautiful right now.
The Economics of Existential Dread
Modern behavioral economists have a term for this: "present bias" — the tendency to overvalue immediate rewards relative to future ones. But they usually study it in lab settings with college students choosing between $10 today or $15 next week. Medieval Europe ran the experiment at civilization scale.
Post-plague spending patterns reveal something crucial about human psychology: we're not naturally long-term financial planners. We're short-term survival machines that learned to delay gratification through social conditioning. When that conditioning gets disrupted by mass mortality, we revert to older patterns.
The archaeological record backs this up. Excavations of post-plague settlements show dramatic increases in luxury goods, imported items, and decorative objects compared to pre-plague sites. People weren't just buying necessities — they were buying meaning, beauty, and experiences.
A 1353 tax record from Florence shows that silk merchants saw their sales increase by 400% in the two years after the plague's peak. Wine imports doubled. Goldsmith commissions tripled. This wasn't economic recovery — it was economic transformation driven by psychological transformation.
Your Pandemic Brain on Shopping
Fast-forward to March 2020. Suddenly, everyone was confronting their own mortality while stuck at home with nothing to do but scroll through shopping apps. The result was entirely predictable to anyone who had studied post-crisis spending patterns.
Online retail sales jumped 44% year-over-year in 2020. But more revealing was what people bought. Home improvement supplies, luxury comfort items, hobby equipment, and "experience goods" like cooking gadgets all saw massive spikes. People weren't just buying stuff — they were buying the same categories of meaning and comfort that post-plague Europeans had purchased centuries earlier.
The psychology is identical. When faced with mortality and uncertainty, humans seek to assert control through consumption. We buy things that make us feel safe, comfortable, or capable. We invest in our immediate environment because it's the only space we can control. We purchase tools for new skills because learning something feels like growing instead of just surviving.
Even the specific irrationalities match. Medieval plague survivors were documented buying expensive clothing they rarely wore, just like pandemic shoppers bought bread makers they barely used. The purchase isn't really about the object — it's about the possibility the object represents.
Why This Keeps Happening
Every generation thinks their crisis spending is unique, but the pattern is ancient. After the 1918 flu pandemic, Americans bought cars, radios, and household appliances at unprecedented rates. After WWII, suburbanization was driven partly by families who had saved money during wartime rationing and partly by people who had seen enough death to want to focus on life.
The pattern persists because the underlying psychology never changes. Humans are loss-averse creatures who normally plan for the future based on the assumption that patterns will continue. When a crisis breaks those patterns, we temporarily lose our ability to project into the future with confidence.
In that psychological space, immediate consumption makes more sense than delayed gratification. The bread maker might be stupid, but it's stupid in a tangible, controllable way. Your 401k might disappear in the next crisis, but the bread maker is sitting right there on your counter.
The Historical Comfort of Predictable Irrationality
Here's the strange comfort in all this: your pandemic shopping wasn't a personal failing. It was your brain following a script written by centuries of human experience with mortality and uncertainty. The medieval plague survivors who bought silk they didn't need were responding to the same psychological pressures that made you buy that thing you're probably looking at right now.
This doesn't mean crisis spending is smart financial planning. But it does mean it's predictably human. And recognizing the pattern might help you understand why your relationship with money feels different now than it did in 2019.
Because once you've lived through a mass mortality event, even a relatively mild one, your brain's assumptions about the future are permanently recalibrated. The economists can call it irrational all they want. History suggests it's just human.
