Key Insight
Measuring experienced well-being can be achieved through methods like 'experience sampling' (random prompts for real-time reports of activities and feelings) or the 'Day Reconstruction Method' (DRM). DRM involves reliving the previous day episode by episode and rating emotions (0-6 scale) and time spent, yielding a duration-weighted measure of affect. The 'U-index' (unpleasant-index) quantifies the percentage of time spent in an unpleasant emotional state (where negative feelings outweigh positive ones), with American women spending 19% of their time unpleasantly, compared to 16% for French and 14% for Danish women.
The U-index reveals significant inequality in emotional pain, with about half the population reporting no unpleasant episodes, while a minority experiences substantial distress. Specific activities have varying U-indices: for American women, morning commute was 29%, work 27%, childcare 24%, housework 18%, socializing 12%, TV watching 12%, and sex 5%. Emotional well-being is strongly influenced by current circumstances and attention. However, 'life evaluation' (e.g., assessing overall life satisfaction on a 0-10 ladder) is distinct from 'experienced well-being'. Higher income, beyond approximately $75,000 household income (in high-cost areas), increases life satisfaction but has no further positive effect on experienced well-being; it may even reduce the ability to enjoy small pleasures.
The 'focusing illusion' is a cognitive bias where any aspect of life currently brought to attention is exaggerated in its perceived importance for overall well-being. This leads to 'miswanting' or errors in affective forecasting. For example, people mistakenly believe Californians are happier due to climate, overlooking that climate is rarely a conscious thought in daily life. This illusion combines 'WYSIATI' (what you see is all there is) with a form of 'duration neglect', as people fail to consider how infrequently they attend to many life circumstances. It causes individuals to overestimate the long-term benefits of initially exciting acquisitions (like a new car) while underestimating the sustained value of attention-demdemanding activities like social interactions.
