Happiness fast and slow?

Abstract While in his early years, Kahneman followed the world of classic utilitarianism in which smart individuals base decisions on how they will truly feel each moment in the future, Kahneman in Mandel (2018) adopted a very different position, namely that what matters is the story people tell of their lives. He thus grappled with evolving stories of both the future and the past, and the presence of different decision-supporting evaluations for the short-run and the long-run.
