I read somewhere that it was a myth that willpower is a limited resource and that we imagine it is limited, but it's not. Does anyone else remember where this was mentioned?
Just skimmed it, but in this study 60 students were given tasks and those who believed that willpower is a limited resource made more mistakes after doing a "willpower-draining" activity.
But I wonder if people who were already willpower-drained before taking this test would be more likely to report that willpower can be drained than well-rested students.
