Daily Inspiration Quote by Ronald Fisher

Fisher is puncturing the piety that often surrounds statistics: stop treating ANOVA like a sacred law of nature. By calling it "not a mathematical theorem" he’s drawing a hard line between inevitability and instrument. ANOVA doesn’t descend from the heavens; it’s a bookkeeping device that organizes sums of squares so you can ask a particular kind of question efficiently: where is the variation coming from, and how much of it can plausibly be attributed to factors you manipulated?

The phrasing is slyly demystifying. "Convenient" sounds modest, almost offhand, but it’s also a power claim. Fisher built much of modern experimental design, and he understood that the authority of a method often comes less from deep truth than from its usefulness and its packaging. Arrange the arithmetic the right way and you get an F-statistic, a p-value, and a decision pipeline that feels objective. The subtext: objectivity is partly choreography. The method’s persuasive force relies on how cleanly it partitions mess into labeled buckets (treatments, error), and how readily institutions can standardize around those buckets.

Context matters: Fisher was fighting on two fronts - against loose, narrative inference in biology and agriculture, and against overconfident mathematical formalism that pretends data analysis is deduction. ANOVA sits in the middle: rigorous enough to discipline inference, pragmatic enough to run on real experiments. The line reads like a warning from the architect himself: don’t confuse the furniture of analysis with the building of knowledge.
