Most questionnaires to obtain reports of happiness are primitive with the results obtained of low (interpersonal) comparability. This paper argues that happiness is intrinsically cardinally measurable and comparable though with many difficulties. Moreover, a sophisticated questionnaire was developed and used to obtain more accurate and interpersonally comparable reports of happiness based on the concept of just perceivable increments of pleasure/pain. Comparisons with the traditional questionnaire are also made (by the respondents) to show the superiority of the sophisticated questionnaire.
- Cardinal utility
- Interpersonal comparison
