[L]et there be granted to the science of pleasure what is granted to the science of energy ; to imagine an ideally perfect instrument, a psychophysical machine, continually registering the height of pleasure experienced by an individual, exactly according to the verdict of consciousness, or rather diverging therefrom according to a law of errors. From moment to moment the hedonimeter varies; the delicate index now flickering with the flutter of the passions, now steadied by intellectual activity, low sunk whole hours in the neighbourhood of zero, or momentarily springing up towards infinity. The continually indicated height is registered by photographic or other frictionless apparatus upon a uniformly moving vertical plane. Then the quantity of happiness between two epochs is represented by the area contained between the zero-line, perpendiculars thereto at the points corresponding to the epochs, and the curve traced by the index; or, if the correction suggested in the last paragraph be admitted, another dimension will be required for the representation.

Consistent with Bentham’s ideal of “the greatest happiness of the greatest number”, the quality of our world or universe (QW) could be assessed in terms of the ratio or quotient of the magnitude of the sum total of the subjective well-being (SWB) scores of everyone in the world or universe divided by the standard deviation of the distribution of all of the SWB scores.

In a similar way as the Dow Jones Index provides a means of assessing broad-based economic strength, this ratio, the QW, would provide a means of assessing broad-based (ideally universal) happiness and other aspects of SQB. It might also serve as a means of determining whether or not the lot of humankind were actually improving over time, that is, whether or not the changes which will come about in the world will actually be constructive. The larger the value of QW, the more worthwhile, humanistic, and heavenly we could consider our world to be.

[M]oment utility is measured by collecting introspective reports, but this […] is not necessary. Appropriately validated physiological measures of moment utility could be used instead, and may have important advantages. The most promising physiological indicator of momentary affect is the prefrontal cortical asymmetry in the electroencephalogram (EEG), which has been extensively validated by Davidson and his team as a measure of the balance of positive and negative feelings, and of the relative strength of tendencies toward approach or avoidance. A portable measuring instrument is not yet available, but is technically feasible. When success is achieved, Davidson’s technique will be a candidate for a continuous and non-intrusive indicator of moment utility.
