Alpha inflation occurs when running multiple statistical tests at p < .05 — 20 tests give a 64% chance of at least one false positive, not 5%. Methods to control it (Bonferroni, Tukey) reduce false alarms but increase misses (Type II errors), so the decision depends on whether a false alarm or a missed real difference is more costly in your context
Why Technical Context Matters in UX Research (And How to Capture It Properly)
UX research in "clean room" conditions (perfect prototypes, high-speed internet) creates a false reality — when products hit the real world (slow databases, legacy systems, patchy networks), they fail. The fix: conduct on-site observations, map architecture with engineers, simulate real conditions (throttle networks, test on actual devices), and bridge design-engineering early
Some Bugs Don’t Throw Errors. They Just Make People Give Up
A founder watched a real user struggle and found "silent bugs" — problems that don't throw errors (logs are spotless) but quietly do the wrong thing (folder index lag, background refresh wiping unsaved edits). These bugs create churn with no signal: users don't report them, they just give up — and the only way to find them is watching real people use the product
NNG: Don’t Outsource the Learning - Why Human-Led Research Still Matters in the Age of AI
Even if AI matches research output quality, human-led research remains essential because research produces both findings (which AI can generate) and learning — the shared experience of observing users and being moved by their stories, which can't be outsourced. Stories engage the brain deeply, drive empathy and action, and the self-generation effect means the effort of deriving insights makes them memorable; protect the parts where learning lives (moderating, observing live, interpreting), and use AI only for support work that teaches nothing
Prototyping: Aesthetically Pleasing, Functionally a Disaster
A UX critique of a stunning but broken AI model selector: the beautiful grid implies every model supports every effort level, but real capabilities don't align — unsupported combinations create unsolved states, and Ultra breaks the mental model by leaving the scale as a dramatic glowing lever. The takeaway: polish is a layer, not proof — good UI earns attention, but good UX survives interaction; the live version is less cinematic but more honest because it maps one control to one decision
AI: Research Was Never About Speed, and AI Proves It
Research was never about speed — AI takes execution (transcription, first-pass synthesis) but leaves judgment (interpreting nuance, framing questions), which was always the point. The risk of flattening comes from process failures (treating summaries as findings, skipping raw data), not the tool — the cheaper execution gets, the more deliberate judgment must be
Opinion: You’re Ignoring Your Best UX Research Tool
Your support inbox is one of your best UX research tools: every support conversation is a raw usability test where users describe the gap between expectation and reality — patterns across tickets reveal design problems that analytics alone can't explain. Spend 20–30 minutes weekly reviewing support conversations, look for recurring language, and bring insights into design critiques — research happens every time a user struggles, not just when you schedule it
Basics: Stop Interviewing Your Users. Go Watch Them Work
A practical guide to Contextual Inquiry: instead of interviewing users (which gets polished summaries), go watch them work in their actual environment — people can't accurately tell you what they do because expertise hides in invisible micro-decisions. Key principles: be the apprentice, go where the work is, build a partnership, interpret out loud, and convert "solution" questions into "how do people actually work?" questions
