 To measure happiness through self-reports, then, it may be wiser to employ terms other than ‘happiness’ and its cognates—terms whose meaning is relatively well-known and fixed. In other words, researchers should decide in advance what they want to measure—be it life satisfaction, hedonic state, emotional state, or something else—and then ask questions that refer unambiguously to those  states.[14]  This stratagem may be all the more necessary in cross-cultural work, where finding suitable translations of ‘happy’ can be daunting—particularly when the English meaning of the term remains a matter of contention (Wierzbicka 2004).
