The IKEA effect is a cognitive bias where consumers put a high value on products they have partially created or assembled. It takes its name from Swedish furniture company IKEA. Designers involve users in the creation or customization process, so users feel more competent and bonded with products.
Why is there an IKEA Effect?
The IKEA experience is famous for consumers assembling a wide range of furniture they buy in flat-packed boxes. IKEA is an extremely popular option for consumers who return to this successful brand for their furniture needs—among other quality goods. However, there’s a deeper aspect to customers building their own chairs, tables and more, and it’s not just about the end product or the amount of time they put into it. This “IKEA effect” can significantly influence a product's—any buildable product’s—perceived value and customer behavior. It suggests that people put higher value on products they’ve had a hand in creating.
Professor at Harvard Business School, Michael Norton coined the term “Ikea effect” in a 2011 study. Norton and his colleagues conducted a series of experiments where they examined and explored the psychological phenomenon behind the IKEA effect. They found that when individuals put effort into creating or assembling a product, they typically value it more highly than if they’d purchased one that had already been assembled in the store. What’s more, that’s true even if the end result isn’t objectively better than a pre-made alternative. So, the effort that consumers put into completing a product from pieces to its final state transforms into an actual affinity for that product. It’s something that makes its subjective value higher compared to a pre-assembled equivalent product.

The IKEA Effect in User Experience (UX) Design
The IKEA effect certainly translates to the real world of user experience (UX) design, user interfaces, and product development. When you involve users in your product’s—or service’s—creation or customization process, it becomes a personal and emotional thing for them. For example, you can do this when you let users:
Personalize their app interfaces.
Build their profiles on a website.
The basic key is to give users control over aspects of the product and make the execution as simple as possible. You can empower users to do this whether you’re working on an existing product or starting a totally new one.

Allowing users to put some effort into a product lets them value it more highly—and more—such as thinking carefully before proceeding.

Benefits of the IKEA Effect
Here are some pros of the IKEA effect to users of the products (and services) a designer might set before them.
It gives them a sense of accomplishment and competence when they successfully complete a task.
That “job well done” enhances their experience and satisfaction. It means that products include a high quality of joy and attachment for their target audience—something that boosts the customer experience.
It can nurture a stronger emotional connection between the brand and its customer base.
Users in the target market will be more loyal. What’s more, the IKEA effect can bolster the final product’s perceived value—and makes it more desirable and enjoyable for the users.

Risks of the IKEA Effect
While there are pros, here are some cons of the IKEA effect for designers and product managers to think about:
The Potential for Bias
When people become emotionally invested in something, they might end up overlooking or downplaying its flaws. That can lead to a biased assessment of its value. This, in turn, can get in the way of objective evaluation and prevent a design team from making improvements or changes it needs to. So, the product or service may need improvements that solid usability testing or an expert evaluation would expose.
The Tendency to Overestimate Market Demand for a Self-Made Product
Just because an individual values their creation highly, it doesn't mean that others are going to share the same sentiment. That’s something that can lead to unrealistic expectations and difficulties in successfully marketing or selling the product. So, it can put a design team members’ time—and money—invested in the project at risk.
Complacency and Resistance to Feedback
When people are highly attached to their creation, they may be less open to constructive criticism or suggestions for improvements to it. This can limit growth and innovation—plus, it can hinder collaboration and learning from others. One example of a phenomenon like this might be the Facebook shift to the Timeline format in 2012. As Facebook had let users put so much into their profile pages beforehand, many users weren’t too happy about going along with the new, improved version.
A Sunk Cost Fallacy
People may feel hesitant to abandon or change a project they’ve invested a lot of time and effort into—and that’s true even if it’s no longer viable or beneficial. This can lead to wasted resources and missed opportunities to go after more promising endeavors. In UX terms, that means if users have had a hand in co-creating a design, they may cling to it even if the user research shows that a change is indeed in order.

How to Leverage the IKEA Effect in UX Design
Designers can factor the IKEA effect into their product development process whenever they create products or services that call for user involvement. Designers can do this if they:
Customize the product or service, engaging users in the design process—or letting them assemble or create a part of the product. A designer could—in fact—have users fully on board in a participatory design approach. This could manifest in many forms—like, for example, potential customers getting involved in the information architecture or visual design of what a designer wants to make for them.
Keep a sharp eye for how to involve users. Aim to create an interaction design product where the level of effort is low but the perceived contribution is high. User feedback should confirm that designers have hit the right formula where their users and product ideas meet.
Use editable templates and sample data to achieve the IKEA effect—and make the app feel dynamic and alive to the users. So, design for simple actions that call for low effort but that make the user feel they've contributed a great deal. It’s something that can lower their fear of dealing with a new product. Do it right and it can lead to users forming loyalty to a brand and product.

The formula is simple, although the considerations—and possibilities—are numerous.

Best Practices and Tips
Consider the following best practices and tips to make the best of the IKEA effect for your users:
Keep tasks simple: The IKEA effect works best when tasks are simple and straightforward for users to complete. Tasks that are overly complex can frustrate users and might even put them off completing the product.
Provide clear instructions: Users should have clear and concise instructions to make sure they finish tasks successfully.
Balance effort and reward: The level of effort that users need to put in should be in proportion to the perceived value of the finished product. If the effort required of them is too high—or the contribution the brand rewards them with too small—people probably won't complete the task.
Test and iterate: Do solid user testing to understand how users interact with the product—and then iterate based on their feedback.

The IKEA Effect in Action: Brands Doing It Right
Several brands have been successful in how they’ve harnessed the power of the IKEA effect. For example, Apple lets customers customize their devices—and that goes from choosing custom configurations to adding personal engravings. This level of personalization instills a sense of ownership in customers and a higher perceived value of the product among them. These are qualities that also can be helpful when it comes to marketing campaigns.
Remember, it's vital to strike a balance between the level of effort that the user has to put in and the reward they perceive they’ll get. This is where it might be helpful for a product designer to think of LEGO. By giving customers the chance to construct their own toys, LEGO taps into the satisfaction and sense of accomplishment that comes with creating something from scratch. When UX and UI designers transfer that spirit—and do it well—they can fine-tune engaging and satisfying experiences that keep customers coming back for more.
