Sun and water: On a modulus-based measurement of happiness

Most happiness researchers use semantic differential or Likert scales to assess happiness. Such conven-tionally used scales are susceptible to scale renorming (interpretation of scales differently in different contexts) and can produce a specious relativism effect (e.g., rating a low-income person happier than a high-income person in situations where the low-income person is not happier). Building on related psychophysical measurements, the authors propose a simple, survey-friendly, modulus-based scale of happiness and show that it is less susceptible to specious relativism than conventional rating scales but can still catch genuine relativism (e.g., rating a low-income person to be happier than a high-income person in situations where the low-income person is indeed happier)
