Ego depletion

Reviewed by expert Scientifically proven

Ego depletion is a cognitive bias that refers to the idea that our willpower and decision-making abilities are limited and can be depleted over time. Essentially, this means that making decisions or exerting self-control in one area can make it more difficult to do so in another area. For example, if you spend all day resisting the temptation to eat unhealthy foods, you may find it harder to concentrate on work-related tasks later in the day. This bias has important implications for website design, as it suggests that reducing the number of decisions users have to make on a site can help to maximize their willpower and improve their overall experience.

Certainly! Here is a blog post about ego depletion:

Understanding Ego Depletion

Ego depletion is a cognitive bias that affects our ability to make decisions when we are tired or have exerted a lot of mental effort. It was first studied by psychologist Roy F. Baumeister and his colleagues in the late 1990s. Baumeister believed that our "ego" - our sense of self - was a limited resource that could be depleted through use. He conducted a series of experiments to test this theory.

In one study, Baumeister and his team asked participants to resist eating freshly baked cookies for 10 minutes while they completed a puzzle. Half of the participants were also asked to suppress their emotions while completing the puzzle. Afterward, all of the participants were given the opportunity to eat as many cookies as they wanted. The participants who had to suppress their emotions and resist the cookies ate significantly more than those who only had to resist the cookies. This indicated that the participants who had to suppress their emotions were experiencing ego depletion that made it harder for them to resist temptation.

Another study by Baumeister and his colleagues involved asking participants to watch a video of a person being excluded from a group while also trying to remember random numbers. Participants who had to watch the exclusion video and remember the numbers performed worse on a skill test than participants who only had to remember the numbers. This suggested that ego depletion affects our ability to concentrate as well as our ability to resist temptation.

How to Take Advantage of Ego Depletion in Marketing

Understanding ego depletion can help marketers design their campaigns and websites in a way that takes advantage of this cognitive bias. For example, if you are running a promotion, consider timing it so that it falls at the end of the day or after a holiday when people are more likely to be tired and experiencing ego depletion. This will make them more likely to take advantage of the promotion.

You can also use ego depletion to your advantage when designing your website. For example, you might place your call to action (CTA) at the end of a long page or after a series of difficult tasks, like filling out a form. This will capitalize on the user's depletion and get them more likely to take action.


Ego depletion is a powerful cognitive bias that can affect our decision-making abilities. By understanding this bias, marketers can design more effective campaigns and websites that capitalize on users' depleted states. Remember to time your promotions and CTAs strategically to take advantage of this bias.
