What is this based on?

The Quantified Mood solution is based on a different set of theories than traditional surveys, attempting to minimize both bias and satisficing inherent in survey takers. Inspired by work of Daniel Kahneman and others, Quantified Mood focuses on aggregation of visceral snapshots of moment utility, as opposed to the more overarching and cognition-intense experienced utility. The application is employed as an Ecological Momentary Assessment (EMA), but is more of a continuation of the work of Mihaly Csikszentmihalyi with Experience Sampling Methodology.
