Such an approach to measure happiness is not different from a kindergarten school teacher's approach asking her students to stamp their feet or tap their toes IF they knew they were happy. Even though one can assume that a 'happy' respondent will conduct an action or write a specific response or fill in a box, the mere acts of tapping feet, or clapping hands, or indeed answering questions in an instrument are not indicative of trait happiness. In Epidemiological terms, such measurements are open to response and measurement bias; besides, states of human mind also change as a result of interventions; therefore such measurements are unreliable as traits in response to specific interventions when repeated over a period of time if these interventions are aimed to increase trait happiness \cite{veenhoven2012cross,lim2008use}. We therefore state that happiness is an individual construct rooted in a person's consciousness; and  that measurement of happiness needs to be based both on self report and an  objective measurement using a person's facial and bodily features.
