Correlation (r)
−0.55
Opposite direction across 134 months. Closer to −1 would mean a perfect mirror.

185
Laundry tied bowling’s weirdness band. Strong numbers get easier when you hunt that hard.
A simple correlate-with title on purpose: two real series, one declarative line, and r in the page title — same joke shape as classic Spurious Correlations charts. Pattern match only. Not a claim that one caused the other.
A chart can look convincing even when the two things have nothing useful to do with each other. Saying “among 185 tries” is part of the finding.
If this were causal (it isn’t)
As Minecraft search interest rose, kids wore the same dirt-stained tunic for forty nights. Wikipedia’s laundry page went quiet. Detergent futures… no. That story is the joke. The chart is real. The cause is not.
How laundry tied the bowling band
After checking 185 outside series (prices, jobs, food, and Wikipedia pages), laundry Wikipedia opens landed in the same strong monthly opposite band as bowling: about −0.55 across 134 shared months from mid-2015 through mid-2026.
In plain words: months when Minecraft search interest ran hotter in this window often lined up with quieter laundry Wikipedia traffic, and the other way around. That is a mirror pattern, not a scoreboard of “Minecraft killed wash day.”
Minecraft search interest vs laundry Wikipedia opens
Two different thermometers on one timeline. Green is Google’s relative Minecraft score (0–100 in this window). Orange is how many times people opened Wikipedia’s Laundry page. Opposite slopes can still look “connected.”
Two thermometers, not one story
Google Trends is a relative interest score for the word “Minecraft” in the United States. 100 means the peak in that Trends window. It is not players online.
Wikipedia opens count how often people loaded the encyclopedia page titled Laundry. That is curiosity about washing clothes, not loads started or detergent sold.
Stack those two public charts and you can get a neat opposite move. Stack enough unrelated charts and you should expect neat moves sometimes. That is the whole lesson.

Month-to-month wiggles are much weaker
If I look at percent change from one month to the next, the link shrinks to about −0.13. The big opposite move is more about long shapes of the two charts than about laundry and Minecraft twitching together every month.
That is a useful check. A headline correlation can look fierce while the month-to-month story is mild.
Why publish a fake-looking relationship on purpose
Because the fake-looking part is the point. Chore comedy pairs cleanly with a block game — and that is exactly when you should distrust a neat chart.
Keep the joke. Keep the receipts. Do not keep the causal story.
U.S. Minecraft search interest correlates with laundry Wikipedia opens (r = −0.55, 134 months) — same strength band as bowling among 185 charts I checked. Correlation still is not causation.
How I calculated it
Anchor: Google Trends term “Minecraft,” United States, monthly series I saved (interest above zero). Outside series: Wikimedia monthly pageviews for English Wikipedia Laundry (all-access, user). Overlap: 2015-07 through 2026-08 · n = 134. Pearson r = −0.555 · R² = 0.308 · Spearman ρ = −0.618. Month-over-month % change Pearson r = −0.128 (133 pairs). Parent hunt: 185 catalog series (prices, jobs, food, Wikipedia culture pages), then a weirdness pass for the funniest strong matches.
I searched many pairings on purpose, so a strong match was likely somewhere. Google Trends scores are relative to the peak in that window, not a player count. Wikipedia opens are page loads, not wash cycles. Late months can look thin if the save was incomplete (August 2026 laundry opens look unfinished; dropping that month barely changes r). Opposite movement is not a claim that Minecraft cancelled wash day, or that laundry emptied Minecraft.
