The Doorknob
Intelligence Scale

A rigorous scientific framework for calibrating intelligence, using a standard sack of doorknobs as the universal baseline. Is it dumber? Less dumb? Now you'll know for sure.

What Is the D.I.S.?

The Doorknob Intelligence Scale provides a universal reference point for cognitive calibration.

The Reference Sack — a burlap sack filled with assorted brass doorknobs
Reference Specimen

The Sack™

A standard-issue burlap sack containing exactly 47 assorted brass doorknobs, maintained at room temperature in a climate-controlled facility. This is the baseline against which all intelligence is measured.

How It Works

The DKI (Doorknob Intelligence) score measures cognitive ability relative to a sack of doorknobs.

0
Dumber Than Reference Point Less Dumb
Below Baseline

DKI < 0

−∞ to −0.01

Somehow less intelligent than a literal sack of inanimate metal objects. This is a remarkable achievement in its own way. Subjects in this range include certain government policies and USB cables that never go in the right way.

The Baseline

DKI = 0.00

0.00

Exactly as intelligent as a sack of doorknobs. The reference point. The gold standard. The sack itself. Nothing more, nothing less. It just sits there, being a sack of doorknobs.

Above Baseline

DKI > 0

+0.01 to +∞

More intelligent than the sack. Congratulations. This includes most living organisms, many machines, and roughly 94% of things that exist. The bar is on the floor but some still limbo under it.
