I fine this absolutely fascinating; that when we feel up, we bring ourselves down; and when we feel down, we bring ourselves up. Reminds me of a word I learned in high school biology, “homoeostasis” the way systems self regulate. (https://en.wikipedia.org/wiki/Homeostasis)
Economists will be surprised, rather than individuals optimising short term pleasure we self regulate to long term satisfaction. And that is important as we strive to move from short term economic and political systems to longer more sustainable ones.
Scientists have developed a smart phone app to collect large-scale data about human behavior and demonstrate how humans routinely sacrifice their short-term happiness for their long-term welfare.
