Send us Fan Mail Accessibility is not a final checklist. It is a shared responsibility that should shape a product from the beginning. In this episode of The Design Psychologist, Thomas Watkins talks with David Sloan, Chief Accessibility Officer at TPGi and co-author of What Every Engineer Should Know About Digital Accessibility. David explains how designers can look beyond visual considerations like color contrast and account for the different ways people perceive, navigate, and operate technology. They discuss assistive technology, screen readers, semantic HTML, linearization, disability language, and the difference between accessibility needs and medical diagnoses. The conversation also explores why accessibility works best as a team effort. Designers, developers, product managers, writers, and testers all make decisions that can either create or remove barriers. If you want to build more inclusive products—and make accessibility part of your everyday workflow—this conversation offers a practical place to begin.

Send us Fan Mail What makes a product feel not just usable, but desirable? In this episode of The Design Psychologist, Thomas Watkins talks with Marty Gage, co-author of User Experience Research: Discover What Customers Really Want, about how teams can move beyond guessing and uncover the experiences people actually desire. Marty shares a practical framework for connecting emotional needs to product strategy: desired emotional states, benefits, features, and sensory cues. They discuss why great design is not just about making something easy to use, but about understanding how people want to feel, what value they want from an experience, and what details communicate that value. The conversation explores useful, usable, and desirable design, the meaning behind cues like simplicity, familiarity, organization, and accessibility, and how methods like collaging and contextual inquiry can help teams translate customer insight into actionable design direction. If you want to build products and services that connect with people, align teams, and reduce the risk of guessing wrong, this episode offers a clear way to think about user experience research as the foundation for better innovation.

Send us Fan Mail How many users do you actually need for a usability study? In this episode of The Design Psychologist, Thomas Watkins talks with Laura Faulkner about one of the most repeated ideas in UX research: that five users are enough. Laura explains why that rule of thumb can be useful in some situations, but dangerous when teams treat it like a law. They discuss sample size, research risk, stakeholder alignment, and why the real question is not “How many users?” but “What decision are we trying to support, and what happens if we miss something important?” Laura also shares practical advice on making research more influential inside organizations: sharing early and often, treating research as community property, helping stakeholders take ownership of findings, and building a point of view from human data rather than personal opinion. The conversation also explores synthetic users and AI, including where AI can help researchers think through test plans and where teams still need fresh data from real people. If you want to design better studies, communicate findings with more impact, and help research actually change product decisions, this episode gives you a grounded, human-centered way to think about evidence, risk, and influence.

Send us Fan Mail What does it actually mean to say a product is usable? In this episode of The Design Psychologist, Thomas Watkins talks with Phil Kortum about the System Usability Scale, or SUS: one of the most widely used tools for measuring usability. They discuss why this 10-item questionnaire has lasted for decades, what makes a usability metric trustworthy, and how researchers can use SUS scores to compare products, track improvement, and communicate usability in a shared language. The conversation covers why a number is not automatically objective, how SUS differs from measures like Net Promoter Score, when the positive version of SUS may be better to use, and why usability researchers still need effectiveness and efficiency measures alongside subjective ratings. They also explore Phil’s work on voting systems, where usability is not just about convenience but whether people can successfully cast a vote. If you want to understand how to measure human experience with more rigor, this episode gives you a clearer way to think about usability, evidence, and the difference between a score that sounds scientific and a metric you can actually trust.

Send us Fan Mail How do you know whether a product idea is worth building before you spend months designing and developing it? In this episode of The Design Psychologist, Thomas Watkins talks with Jaime Levy, author of UX Strategy, about how designers, researchers, founders, and product leaders can move beyond opinion and make a stronger evidence-based case for what to build. Jaime explains why strategy is not about magically predicting the future, but about systematically reducing risk. She discusses how storyboards can help teams test the business idea before getting lost in interface details, why most companies compete in “purple oceans,” and how UX can become a source of real differentiation. The conversation also gets into AI: where it can speed up strategy work, where it can mislead us, and why human judgment, critical thinking, and customer understanding matter even more as tools become more powerful. If you care about building products people actually want, this conversation will help you think more clearly about value propositions, mental models, product differentiation, and the role of UX strategy in a rapidly changing world.

Designers are trained to make things easier to use—but what if ease and elegance are no longer the point? What if the systems we need to change go far beyond screens and interfaces, touching global structures and collective futures? Our guest, Don Norman, coined the term "Norman Door" to describe a door that gives the wrong signal about how to open it—pull vs. push—highlighting poor affordances and feedback in everyday objects.  This simple yet profound observation helped launch a new era of design awareness, making him one of the most influential voices in the psychology of design. His decades-long career has shaped the fields of human-computer interaction, design thinking, and usability. He is the author of the seminal book The Design of Everyday Things, and now, Design for a Better World, a work that challenges us to design for the full complexity of human and planetary needs. WHAT WE COVER IN THIS EPISODE What makes some errors easy to catch and others dangerously hard to detectHow decades of design decisions have shaped today’s global challengesWhat it means to shift from human-centered to humanity-centered designHow co-design empowers communities over outside expertsThe surprising design lessons learned from nuclear accidents, faucets, and guinea pigsThe role of failure in progress—and why we should embrace it KEY TAKEAWAYS Designing for ease is not enough—today’s challenges demand designing for systems and long-term impact.User-centered design can fall short when it fails to consider environmental, societal, and ethical dimensions.Human error is not always a failure of attention—it’s often a byproduct of bad design.To scale real change, we need dandelion models—spreading seeds of knowledge and training others to do the same.Participatory design ensures that communities are not passive recipients but active creators of their own solutions.The service economy offers a path toward sustainability—if companies rethink profit and longevity.The future of design psychology isn’t about better buttons—it’s about understanding people so deeply that we can redesign society itself.

And, what are some practical tips on how to use it to create better designs? In part one of these Social Proof episodes, we started with the foundations of social psychology. We looked at the history, key studies, and some helpful frameworks. Now in part two, we’re picking up where we left off—at the five-point framework I mentioned at the end of Part One. This is where things get practical. We’ll connect the social psychology research with actual strategies for implementing social proof.  We’ll explore how social proof methods like testimonials, expert endorsements, and more, have an impact on our psychology, in particular, when we’re making buying decisions. By the end, you’ll have a framework to decode social proof and a toolkit to apply it thoughtfully. What You’ll Learn Five core psychological drivers— including our need to fit in, our fear of missing out, and so on  How social proof methods like testimonials, expert endorsements, and more, have an impact on our psychology, in particular, when we’re making buying decisions. A framework to decode social proof and a toolkit to apply it thoughtfully. Key Takeaways We relate to other humans, and shared experiences matter.We want to fit in—and social proof taps into that drive.We trust experts when making decisions under uncertainty.We’re motivated by FOMO (fear of missing out).Imagination helps us take action when we see others doing the same.These drivers explain why social proof works. We respond to stories, signals, and shared experiences because they tap into how our minds are wired. We also explored how to use social proof in design. Whether it’s testimonials, expert endorsements, client logos, or user-generated content, each method works best when it feels real, relevant, and respectful. The goal isn’t to trick users—it’s to guide them with clarity, trust, and connection.

Or walked past two restaurants—one bustling with a line out the door, the other nearly empty—and felt pulled toward the busy one? These small, everyday moments reveal something big: we are profoundly influenced by the people around us, often without even realizing it. This episode kicks off a two-part deep dive into social proof, one of the most powerful concepts in social psychology. Over a century of research shows that humans are wired to pick up on social cues, and these cues quietly shape our behavior, decisions, and preferences. In Part 1, you’ll learn: Why simply being around others can change how we perform.How reviews, testimonials, and follower counts tap directly into our social wiring.The fascinating story of a 19th-century psychology professor who first noticed how cyclists behaved differently when riding together.How social proof research has evolved from early experiments in social psychology to today’s social neuroscience.The key psychological principles that explain why social proof works.This episode is about more than just marketing or design tricks—it’s about understanding the deep human need to notice, follow, and be influenced by others. By grasping the science, you’ll build a foundation for creating products, experiences, and messages that feel natural, trustworthy, and even irresistible. What’s next: In Part 2, we’ll move from theory to practice. You’ll get concrete methods and examples to put social proof to work in your own designs and projects.

Send us Fan Mail Why are games so deeply engaging? What psychological principles make game design such a powerful tool for shaping attention, emotion, and learning? Game design is not a niche skill. It's one of the most refined disciplines we have for designing attention, emotion, and motivation. If you're designing anything for people, game design can sharpen your craft.  This episode reveals how the craft of game design can teach us to build more immersive, emotionally resonant experiences. Whether you're designing products, learning experiences, or interactive systems, the lessons from games can help you design for joy, focus, and transformation. About Our Guest: Jesse Schell is a legendary figure in game design. He’s designed games for Disney, pioneered virtual reality, built theme park attractions, created award-winning educational games, and teaches at Carnegie Mellon’s Entertainment Technology Center. His book, The Art of Game Design, is one of the most widely recommended texts in the field. What You'll Hear: Why game designers focus on creating experiences, not just productsThe surprising power of introspection in understanding usersHow "toy-first" thinking leads to more meaningful playThe science behind flow and how it keeps players engagedHow to use emotional arcs and tension-release patterns in your designsWhy gamification often fails—and what to do insteadThe psychology of challenge, curiosity, and funWhat designers in other fields can borrow from gamesQuestions Explored: What is the difference between a toy and a game?How do we design for emotional resonance?Can introspection really be a reliable design method?What does it mean to balance choices and desires?Why is iteration crucial to creating fun?Key Takeaways: Games are machines for generating experiences. That means the psychology of the player is central to every design decision.Designers must understand not just what people do—but why they feel, focus, and engage.Play is not trivial. It's one of the most powerful modes of learning and transformation.Flow, balance, and emotional arcs aren't just game design tools—they're experience design tools.To make things more engaging, don’t just "gamify"—design for meaningful engagement.

Send us Fan Mail What is the sweet spot between new and familiar, and how do you design for it? Create products that feel groundbreaking and instantly intuitive by applying the psychology of the MAYA Principle. By unpacking how humans respond to familiarity and novelty, you’ll gain practical guidance for designing experiences that spark excitement without overwhelming users. WHAT WE COVER IN THIS EPISODE What is the MAYA Principle, and why does it matter for product and experience design?How do familiarity and novelty interact to shape user adoption?Why did products like the iPad feel revolutionary and intuitive to use?When should you release a big innovation versus gradually introducing features?How psychological barriers like loss aversion affect how people receive new ideas.How designers can pace innovation to keep users comfortable and engaged. KEY TAKEAWAYS The MAYA Principle stands for "Most Advanced Yet Acceptable"—a formula for balancing innovation with usability.People adopt new ideas more readily when they resemble something they already understand.Successful products often anchor new concepts in familiar mental models (e.g., Uber reimagined the taxi).Understand your audience: tech-savvy users tolerate faster change than general users.Manage the speed of innovation—disruptive or incremental—based on what your users can handle.Incorporate user feedback early and often to gauge readiness and reduce risk.Frame change as a gain, not a loss, to overcome psychological resistance like loss aversion.Design psychology empowers us to bridge users into the future—delighting without alienating them.Go to thedesignpsychologist.substack.com to get episode summaries right in your inbox so you can easily reference, save, and apply what you learn.

Send us Fan Mail What shapes the memory of an experience, and how can designers use that insight to create better, more human-centered products? Design more memorable and emotionally resonant experiences by understanding how people actually remember what they go through. It turns out we do not remember experiences by their length, but by their intensity and how they end. By uncovering the psychological principle known as the peak-end rule, you will learn how to shape experiences that stand out in people’s minds, leading to better outcomes and more impactful design.  WHAT WE COVER IN THIS EPISODE Why do we forget most of what we live through?What is the peak-end rule, and how does it influence memory?Why do people sometimes prefer longer discomfort over shorter pain?Should designers focus on the peaks and endings of an experience instead of the whole journey?Which types of experiences are a poor fit for the peak-end rule?How do memory and actual experience compare when it comes to decision-making?What are the two different selves described in happiness research, and how do they shape our reactions? KEY TAKEAWAYS The peak-end rule suggests we remember the most intense moment and the ending of an experience. Most of the rest fades from memory.Designers cannot control every moment, but they can influence how an experience is remembered.This principle is especially helpful when designing uncomfortable or tedious processes. A well-placed positive moment or thoughtful ending can shift how the whole experience is recalled.Duration neglect means people do not remember how long something lasted, only how it felt at key moments.The remembering self often outweighs the experiencing self when people decide whether to repeat an experience.Linear experiences like onboarding flows or customer service calls are ideal candidates for applying the peak-end rule. More complex or non-linear experiences, such as websites or productivity apps, may require different strategies.Go to thedesignpsychologist.substack.com to get episode summaries right in your inbox so you can easily reference, save, and apply what you learn.

Send us Fan Mail What’s the best way to choose how you’ll teach something so it actually sticks? Design your next lesson so learners don’t just follow along—they understand, remember, and apply their new skills. By grounding your instruction in Cognitive Load Theory, you’ll gain a practical compass for sequencing content, trimming unnecessary load, and accelerating real mastery. Our guest, Dr. John Sweller, pioneered Cognitive Load Theory during more than four decades as Professor of Educational Psychology at the University of New South Wales.
