Adults who have tried sushi

As more American adults have tried sushi, more Americans have died falling out of bed, a correlation of 0.997 that suggests either that raw fish causes restless sleep or that both metrics are simply measuring the slow, irreversible broadening of American experience—culinary and gravitational alike. The data is so tight it looks like one variable is causing the other, which it absolutely is not, but the scatter plot does not come with a disclaimer.

The percentage of American adults who have tried sushi grew steadily as Japanese food went from exotic to ubiquitous—sushi is now available at airports, gas stations, and grocery stores, and "have you tried sushi" has become a generational question where younger cohorts approach 80 percent. Bed-fall deaths rose as the population aged. Both metrics are smooth upward curves over the same seventeen-year window: sushi adoption grows because cultural tastes evolve, and bed falls grow because demographics shift. Two perfectly monotonic trends will always produce a near-perfect correlation.

A correlation of 0.997 between sushi adoption and bed-fall deaths is a masterclass in the meaninglessness of high coefficients. The sushi spreads, the elderly fall, and the chart produces a number so close to one that it parodies itself. Cultural sophistication and geriatric vulnerability are both growing in America, for reasons that share nothing except a calendar. The wasabi is sharp. The bed edge is sharper.
