Duration neglect

Reviewed by expert Scientifically proven

Duration neglect is the phenomenon where the length or duration of an event or experience doesn't have much impact on our overall evaluation of it. In other words, we may not place much importance on the length of a positive experience, such as a fun vacation, and may not be bothered by the length of a negative experience, such as a long wait in line, as long as the end result is satisfying. Instead, we tend to focus on the peak or most intense moment of the experience, as well as how it ends, when forming our overall perception of it. Understanding duration neglect can help us design better user experiences and interfaces that focus on creating memorable peak moments and positive outcomes.

Duration Neglect: Why Time Doesn't Always Matter in Decision-Making

When designing a website or app that aims to elicit a certain behavior from its users (such as making a purchase or signing up for a newsletter), it's important to consider the various psychological factors that can influence decision-making. One such factor is duration neglect - the tendency for people to prioritize the magnitude of an experience or event over how long it lasts.

What is Duration Neglect?

Duration neglect is a cognitive bias in which people place little importance on the length of an experience, and instead focus on the intensity of it. In other words, people tend to remember and evaluate experiences based on their most emotionally charged moments, rather than considering how long the experience lasted. This can lead to decisions that are not in the best interest of the individual or organization.

For example, let's say you're designing a website for a travel agency. You want to encourage users to book more expensive, longer trips. With duration neglect in mind, you might think that adding a few exciting or memorable experiences to the itinerary could be more effective than simply adding a few extra days to the trip. Users are more likely to remember and prioritize the exciting experiences, even if they were only a small portion of the overall trip.

How does Duration Neglect Influence Decision-Making?

Duration neglect can influence decision-making in a number of ways. Here are a few examples:

Evaluating Experiences

When evaluating past experiences or events, people often rely on their emotional reactions to certain moments, rather than considering the length of the experience. For example, a person who had a great meal at a restaurant followed by a mediocre dessert may rate the entire experience as positive, rather than considering the relative length of each part of the meal.

Choosing Between Options

When presented with multiple options, people often prioritize the option that offers the most intense experience, rather than considering the duration of the experience. For example, a person planning a vacation may choose a shorter trip that includes a once-in-a-lifetime experience over a longer trip with less exciting activities.

Endowment Effect

The endowment effect is a phenomenon in which people place more value on something simply because they own it. Duration neglect can play a role in the endowment effect, as people may overvalue a short, intense experience they have had in the past simply because it was memorable.

How to Use Duration Neglect to Improve Decision-Making

When designing websites or apps, there are a few ways you can leverage duration neglect to improve decision-making:

Focus on Intense Moments

Rather than trying to lengthen an experience or process, focus on creating intense, emotionally charged moments that users are more likely to remember and prioritize. For example, a retail website might offer a surprise discount code after a user adds items to their cart, creating an exciting moment that makes the user more likely to complete the purchase.

Emphasize Rare, Unique Experiences

People are more likely to remember and prioritize unique experiences, even if they are less frequent or shorter in duration. Consider offering exclusive or rare experiences to users as a way to differentiate your product or service from competitors.

Use Visuals to Highlight Key Moments

Visual elements can be highly effective in highlighting emotionally charged moments and creating a memorable experience. Consider using images or videos to draw attention to key moments or features of your product or service.


Duration neglect is a powerful cognitive bias that can significantly influence decision-making in a variety of contexts. By understanding this bias and leveraging it to create emotionally impactful experiences, web designers and UX professionals can improve outcomes and drive user behavior in positive directions.
