The mantra of modern user experience design is clear: reduce friction, streamline flows, eliminate unnecessary steps. One-click purchasing. Infinite scroll. Auto-play. Swipe to delete. The best interface, we’re told, is the one that gets out of the way, allowing users to accomplish their goals with minimal cognitive load and maximum efficiency.
But what if our obsession with frictionless experiences is actually making products worse? What if some of the most important moments in a user journey are precisely the ones that should require pause, consideration, and yes, a bit of effort?
When Friction Becomes a Feature
Consider the difference between sending a text message and sending an email. Texting is immediate, casual, almost thoughtless. You fire off a quick “k” or a thumbs up emoji without a second thought. Email, by contrast, has built-in friction. You need to add a subject line, craft a proper greeting, maybe even review your message before hitting send. This friction isn’t a bug in email’s design; it’s what makes email appropriate for professional communication, thoughtful correspondence, and messages that carry weight.
The same principle applies across countless design decisions. A “Delete Account” button that requires typing your password and then typing “DELETE” in all caps isn’t bad UX. It’s appropriate friction for an irreversible, consequential action. The multiple confirmation screens before sending money through a banking app aren’t user-hostile obstacles; they’re safeguards that give you a moment to catch errors that could be financially devastating.
The Psychology of Effort
There’s a well-documented psychological phenomenon called the IKEA effect: we value things more when we’ve expended effort to create or obtain them. A bookshelf you assembled yourself feels more valuable than an identical one that arrived pre-built. A meal you cooked tastes better than takeout, even if objectively it doesn’t.
This principle extends to digital experiences. Users who go through a thoughtful onboarding process, who customize their settings, who invest time in setting up their profile, develop stronger attachment to a product. The effort creates commitment. Paradoxically, making certain aspects of your product slightly harder to use can increase engagement and loyalty.
LinkedIn’s profile completion meter is a masterclass in this. Rather than auto-populating everything possible from your resume upload, it asks you to manually add skills, write a summary, request recommendations. The effort required makes your profile feel more valuable because you built it. Had LinkedIn simply generated a complete profile for you, you’d feel less ownership and investment.
Intentional Obstacles and Behavior Change
Some of the most important applications of strategic friction involve helping users make better decisions or break harmful patterns. Instagram’s “You’re All Caught Up” message and time tracking features add friction to mindless scrolling. They interrupt the flow intentionally, creating a moment of awareness that allows users to decide whether they want to keep scrolling or reclaim their time.
Duolingo could make it trivially easy to maintain your streak by letting you bank multiple days in advance or by making lessons absurdly short. Instead, it requires daily engagement and meaningful practice. This friction serves the product’s core purpose: actually helping people learn languages, not just feeling like they are.
Amazon’s “Add to Cart” versus “Buy Now” button represents another thoughtful application of friction. One-click purchasing is brilliant for impulse buys and convenience, but the shopping cart serves a different purpose. It lets you collect items, compare prices, think things over, and make more deliberate purchasing decisions. Both options exist because different contexts call for different levels of friction.
The Dark Side: When Friction Becomes Manipulation
Of course, not all friction is created equal. There’s a dark pattern universe of deliberately bad UX designed to frustrate users into submission or trick them into unwanted actions. Making it incredibly easy to sign up for a subscription but maddeningly difficult to cancel isn’t strategic friction; it’s user-hostile design that trades long-term trust for short-term revenue.
The key distinction lies in intent and alignment with user interests. Good friction protects users from mistakes, encourages thoughtful engagement, and creates value through effort. Bad friction exploits cognitive biases, creates confusion, and serves only the business at the expense of the user.
Unsubscribe processes that require logging in, navigating through multiple menus, answering survey questions, and confirming your choice three times aren’t adding valuable friction. They’re creating obstacles designed to wear you down until you give up. The friction serves the company’s goal of retaining subscribers, not the user’s goal of managing their inbox.
Designing Friction Thoughtfully
So how do you know when to add friction versus when to remove it? The answer requires understanding context, consequences, and user intent.
High stakes demand high friction. Deleting data, spending money, sharing sensitive information, or making irreversible decisions should never be frictionless. Users should have to slow down, confirm their intent, and understand consequences.
Frequent actions should be smooth. Tasks users perform multiple times per day should be optimized for speed and ease. Adding friction to routine operations creates genuine frustration without corresponding benefit.
Learning deserves some resistance. Educational products and tools for behavior change benefit from effort requirements. The struggle is part of the value. Making learning completely effortless often makes it ineffective.
First impressions need balance. Initial onboarding should be smooth enough that users don’t abandon the product, but substantial enough that users develop investment and understanding. Too frictionless and users never truly engage; too difficult and they never get started.
Measuring What Matters
Traditional UX metrics often fail to capture the value of strategic friction. Completion rates, time-on-task, and clicks-to-conversion all bias toward frictionless design. A faster checkout flow looks better in analytics even if it leads to more purchase regret and returns. A one-click unsubscribe appears inferior to a multi-step process in retention metrics, even though it builds long-term trust.
Better measurement requires looking beyond immediate conversion metrics to consider satisfaction, error rates, regret, trust, and long-term engagement. Did users who went through a more effortful onboarding stick around longer? Did the extra confirmation step actually prevent costly mistakes? Do users appreciate the pause you built in, even if it slowed them down?
The Future of Friction
As interfaces become more conversational and AI-driven, the question of friction becomes even more critical. An AI assistant that can execute complex multi-step tasks with a simple voice command is powerful, but also potentially dangerous. “Hey assistant, sell all my stocks” shouldn’t be frictionless. Neither should “book the cheapest flight” without showing you what “cheapest” means in terms of connections, timing, and airline reliability.
The most thoughtful designers will resist the siren song of pure efficiency and instead ask deeper questions: What does this user actually need? What are the consequences if they make a mistake? Where does investment and effort create value? When should we slow people down for their own benefit?
Embracing Resistance
The goal of good UX isn’t to eliminate all friction. It’s to eliminate unnecessary friction while preserving and even introducing friction where it serves users. It’s to make the easy things easy and the important things possible, even if possible means requiring thought, effort, and care.
The best products aren’t always the fastest ones. Sometimes they’re the ones that know when to slow you down, when to make you think, when to ask “are you sure?” before you do something you can’t undo. They respect their users enough to believe they can handle a little resistance when it matters.
In our rush to make everything frictionless, we risk creating interfaces that are fast, efficient, and ultimately hollow. The future of UX isn’t about removing all obstacles. It’s about being thoughtful enough to know which obstacles are worth keeping, and wise enough to design them well.
