System 1: Your Ego Depletion And Limited Self Control

System 1 & Self Control

Let’s play a game and see how your system 1 and 2 are affected:

A salad and doughnut cost £1.10. 

The salad costs one pound more than the doughnut.

How much does the doughnut cost?

Well that’s easy! It’s 10p.

Wrong.

The answer is actually 5p. If the doughnut costs 10p, then the total cost will be £1.20. (10p for the doughnut and £1.10 for the salad). If you do the math you will see the easy, intuitive answer of 10p is incorrect. In addition, 5p is the correct answer. And if you did indeed get it right, you probably had to resist this initial incorrect answer.

Why do you make mistakes with System 1 and 2?

This is a perfect example of your System 2 listening to your System 1. Why? Because it is the easy option. Kahneman and colleagues have done work to argue that System 1 and 2 have personality traits. Although System 2 is logical and reasoning, it can also be lazy. As a result it relies on System 1 in certain situations. We see this also when System 2 is busy or depleted. This has a direct relation to the food we tend to go for. 

What happens when System 2 is busy?

Previous psychological studies have highlighted that when faced with a cognitively demanding task and given temptation, you more likely to give in. For example, you are asked to remember a string of numbers. During this time you are offered a salad or an oozing chocolate cake. You will almost always pick the cake. 

But why is this the case? Baumeister and colleagues named the phenomenon ego depletion. Where an individual’s self-control or effortful will becomes tiring. As a result, as time goes on you are less willing to exert the same effort to maintain self-control. Furthermore, it is clear that mental, emotional and physical functions all use the same mental energy source. As a result, an emotionally draining encounter can make you feel less willing to do the next physical task.

How do you combat these conflicts between System 1 and 2?

So how do we combat these issues we face? Baumeister’s group found that with a strong incentive, people are more willing to maintain their self-control. Furthermore they have more willingness to exert the same effort for the next challenge. For many of us working all day, the lack of willingness to eat healthy or exercise after work can be directly linked to this ego depleted feeling. Or in other words, your System 2 is being lazy and relying on your sweet toothed, System 1 to make decisions.

How do you take control of self-control?

Self-control is one of the hardest traits to obtain because it involves constantly keeping your System 1 in check. By training your System 2 to ignore the cues from System 1, you can help yourself to make better decision. And this can even be in a depleted or busy situation. In addition, giving yourself a strong incentive like a reward for your actions can help you to stay motivated to achieving your goals.
