Since 2009, the Gallup polling firm has surveyed people in 150 countries and territories on, among other things, their daily emotional experience. Their survey asks five questions, meant to gauge whether the respondent felt significant positive or negative emotions the day prior to the survey. The more times that people answer “yes” to questions such as “Did you smile or laugh a lot yesterday?”, the more emotional they’re deemed to be.
