Bayes’ Law in UX Research: The Power and Perils of Priors Bayesian reasoning in UX research uses prior beliefs (like historical benchmarks) combined with new data to update confidence in hypotheses about user behavior, such as task completion rates. The article warns that subjective priors can heavily sway results—strong priors need robust justification, while weak data demands caution to avoid overconfident conclusions NNG: A Concrete Definition of an AI Agent An AI agent pursues a goal by iteratively taking actions, evaluating progress, and deciding next steps. Useful agents must be reliable, adaptive, and accurate Prototyping: Great products are built on the opportunities surrounding them Great products succeed by solving the unmet needs and opportunities around core problems, not just the problems themselves—like how Uber didn't just create rides but built an entire ecosystem around urban mobility gaps. The article emphasizes mapping adjacent opportunities through user journeys to create defensible, expansive product ecosystems that drive retention and network effects AI: The rise of synthetic users Synthetic users—AI-generated personas for UX testing—are rising as fast, scalable alternatives to real participants for early validation, hypothesis testing, and catching obvious friction points. While they excel at speed and cost-efficiency for prototypes and edge cases, the article cautions they're no replacement for human emotional depth, biases, and unpredictable behaviors in final research Experience: I Thought I Knew My Users. Then I Visited Their Homes Visiting users' homes revealed how much richer their real-life context, frustrations, and workarounds were compared to remote interviews or analytics alone. The experience transformed the designer's assumptions into empathy-driven features that better solved actual pain points in daily routines Basics: Unmoderated usability testing — some mistakes to avoid The article outlines common pitfalls in unmoderated usability testing, such as vague task instructions, poor participant recruitment, and skipping pilot tests. Key advice includes writing crystal-clear scenarios, over-recruiting participants to account for dropouts, and allowing ample time since there's no live moderator to guide users Interesting: How LinkedIn Uses UX to Keep You Coming Back (Even When You Don’t Need a Job) LinkedIn keeps people coming back by making the product useful even when they are not job hunting: feed content, networking prompts, profile completion nudges, and social proof all create a habit loop. The piece argues that the real UX goal is retention through relevance, identity, and low-friction re-engagement, not just job search functionality @uxdigest
