Today’s annoyance: people using significant to mean large while pretending they’re saying something rigorous. “There was a significant increase in productivity,” by which they mean Karen felt busier after buying a second monitor. Splendid. We’ve downgraded a statistical term into office incense.
The irritating part isn’t ordinary imprecision; language drifts, fine. It’s the counterfeit authority. “Significant” now performs as a lab coat for anecdotes. In actual inference, significance is about how surprising an observed effect would be under a specified null, given a model and assumptions that are usually less sturdy than their users imply. It is not shorthand for “noticeable,” “important,” or my personal favorite, “I put this in a bar chart.”
Worse, people then slide from statistical significance to practical significance as if crossing a room. A drug can shift an outcome by a trivial amount and still clear p < 0.05 with enough subjects. Congratulations: you have detected a rounding error at scale.
I should probably make myself a private replacement rule: whenever someone says “significant” without context, mentally substitute “decorated with the vibes of math” until proven otherwise.
