We seem to make decisions in more impulsive ways than before. Many of us don’t seem to practice any reasonable amount of self-control. I feel this may be because most of us today just don’t have strong willpower.
Last year I read a book called “Willpower” by Roy F. Baumeister and John Tierney. In it the authors liken willpower to muscle. And just like a muscle willpower can wear out from fatigue. When willpower is worn out, we behave more impulsively. How quickly we drain our willpower depends on how strong it is.
In using our willpower to make decisions we’re using our conscious mind or “System 2” as Daniel Kahneman refers to it in “Thinking, Fast and Slow”. Conscious decision making or thinking is hard! It requires effort and uses a lot of energy in the process.
The body, however, has a limited store of energy. When we are low on energy, this conscious decision making process shuts down and decision making is shunted to the brain’s default decision making process or “System 1.” It doesn’t require much energy; it’s automatic and occurs outside of our conscious awareness. Many of the decisions we make in the default mode are driven by habit.
Conscious decision making generally produces reliable outcomes. We make better decisions with it. Not so with automatic decision making, which has been shown to be error-prone, often in systematic ways. So it’s important that we exercise our willpower; build it up, and make it stronger.
No one can make you exercise your body or mind. That’s a choice you make for yourself. But the results of your choice affects your behavior which in turn affects society. We live in communities and we have an obligation to them: to be the best version of ourselves.
