Captions available

The idea

The difference threshold changes with the starting intensity of the stimulus rather than holding at one fixed amount.

In practice

One added candle is detectable against ten and undetectable against a hundred.

Where people slip

This is why loudness, weight, and brightness controls are built on proportions rather than fixed steps.
