What does dol mean?
A dol is a unit devised for measuring the intensity of human pain. Introduced by American researchers James Hardy, Herbert Wolff, and Helen Goodell at Cornell University in the 1940s, it was intended to bring objective, quantitative rigor to something as subjective as suffering. In their original scheme, the scale ranged up to about ten and a half dols, with each dol representing a defined increment of perceptible pain. Although the concept attracted attention in mid-twentieth-century psychology and medicine, it ultimately fell out of use, since pain resists true standardization across individuals. Today the word survives mainly in historical and scientific contexts, cited as an intriguing episode in the long effort to quantify subjective experience. Its rarity gives it a certain charm: few English speakers know that pain was ever assigned a unit at all, making the dol a memorable example of how science has tried — and sometimes struggled — to measure the immeasurable.
nounA unit used to measure the intensity of pain, originally defined as one tenth of the maximum level of pain a person can endure.
- A unit for quantifying the intensity of pain experienced by a person.
"Researchers rated the patients' discomfort on a scale of dols to compare responses across treatments."
"In early pain studies, subjects described their headaches as ranging from two to six dols."
"The dol never caught on clinically, but it remains a curious footnote in the history of pain research."
Regular plural; typically used when citing values on the experimental pain scale.
"Subjects consistently rated the stimulus above five dols."
Pain was once given its own measuring stick: the dol, a unit invented by psychologists so suffering could finally be put on a numbered scale.

Where does dol come from?
The word dol was coined in the 1940s by Cornell University researchers James Hardy, Herbert Wolff, and Helen Goodell as part of their work on pain perception. It derives from the Latin dolor, meaning pain or grief, the same root that gives English words such as dolorous and dolor. The term reflects the era's ambition to create precise psychophysical scales for subjective experience, though the unit itself never achieved lasting clinical adoption.
How dol is actually used
The dol is chiefly of historical and scientific interest; it appears almost exclusively in discussions of psychophysics and the history of medicine rather than in everyday speech.

A doll is a small model of a human figure used as a child's toy, whereas a dol is a scientific unit of pain intensity.
The dole refers to a charitable distribution of food or money (or unemployment benefits in British English), while a dol measures pain.
