We are inclined to believe that complex solutions and explanations are better than simple ones. The perception of complexity often leads to avoidance.

Economists used to believe that people will always choose the option that maximizes their well-being. But people act against their rational self-interest all the time.

This effect describes our tendency to remember incomplete or interrupted tasks better than completed tasks. Each unfinished task takes up some of your attention, splitting your focus. It also interferes with your sleep.
