Loss aversion

pain felt with loss  >  joy felt with gain

Daniel Kahneman

Humans may be hardwired to be loss averse due to asymmetric evolutionary pressure on gains and losses. For an organism operating close to the edge, the loss of a day's food could amount to death, while the gain of an extra days food could lead to increased comfort but would not lead to a corresponding increase in life expectancy.
