THE QUESTION THIS PAGE ANSWERS
ANSWER FIRSTWhat will the “AI Product Psychology: Design the Feeling” AI learning path help you do?
AI can be slow, uncertain, and opaque even when the underlying system works. Use psychology and product signals to calibrate trust, reduce waiting anxiety, and make the experience feel honest rather than magical. The path contains 19 free notes, each centered on one question you can understand and test.
DECISION RULE
Core themes include Perceived Performance, Waiting and Process Design, Trust and Defense, Mental Models and Anthropomorphism.
TRY NEXT
Begin with “Engineering metrics pass. Why do users still call it slow?,” then choose the next note by the task in front of you.
WATCH FOR
Do not optimize for finishing the list. Explaining one trade-off with your own example matters more than opening more titles.

01Engineering metrics pass. Why do users still call it slow?Same 5-second request races blank freeze, spinner, streaming, and visible steps side by side—feel how identical wall-clock time can differ 3× in feel; then meet three timing quirks of the user's stopwatch↗02The Psychology of Waiting: It Was Never Really About Those 5 SecondsThree laws of waiting with Disney and Houston airport cases; drag the duration slider across three presentation tiers: under 1s show it raw, under 10s must stream, over 10s go async↗03Labor Illusion: Make AI Show Its WorkHarvard study: showing the work makes users happier even when they wait longer. Instant reply vs. visible-process A/B, three birds one stone from visible thinking and retrieval sources, plus three lines you must not cross↗04Peak-End Rule: Users Only Remember the Peak and the EndFour session plots show how average score and memory score diverge; the product version of the cold-water experiment: spend the flagship model on first impression, put validation up front to protect the last step, and save freely in the middle↗05Trust Calibration: The Best Users Are Half-SkepticalFull trust pastes fabricated case law into court filings; no trust turns AI into a paperweight. Judge trust yourself across six scenarios; clickable citations, proxy confidence signals, and conditional warnings↗06Algorithm Aversion: One Mistake and the AI Gets Permanently BlockedDietvorst’s experiment: people abandon an algorithm after seeing it err once—even when it’s more accurate overall. Cast a vote to catch your own bias, then try the attribution translator and tweak-permission switch, and watch how four levers pull the abandonment-rate dial back↗07Defensiveness: Users Aren’t Unable — They’re Afraid to Use ItData, competence, and responsibility defensiveness; sense of control, reversibility, and transparency as three levers; redesign three high-defensiveness designs yourself — watch for buried placebo traps; the hand-off-to-human button paradox↗08Mental Models: Users Brought the Wrong ManualTreat AI as a search engine, a database, a learning apprentice, or a calculator—four mismatches, four kinds of bad reviews. Spot-the-difference across four dialogues, then three correction moves: empty-state examples, boundary-first, and memory visibility↗09How Far to Anthropomorphize, and the Art of AI ApologyCASA paradigm: users will treat AI as a person—you only pick the level. Seat five product types; compare four apology scripts for the same miss; three-elements recipe and the service recovery paradox↗10Honeymoon Cliff: Hype Raises Expectation—Retention Pays It BackExpectation-confirmation theory: satisfaction equals experience minus expectation. Play the gacha to see “demo is P99, users get P50,” drag the hype slider to watch signup conversion and 30-day retention trade off, then flip three levers on the expectation-curve editor↗11AI Label Discount: Same Content, Mark It AI and It Drops in ValueLabel content AI-generated and ratings drop systematically; people who use AI at work still fear being seen. Feel the discount in a double-blind rating, judge five scenes on whether to show the label, drag a wording ladder for depth, then pick the export page users dare to share↗12Cognitive Offloading: Users Rely on You—and Fear Going RustyThe Google effect shows people drop from memory what they can look up; AI expands outsourcing from recall to thinking. Pick an outsourcing checklist to see which offloads are risky, drag the Copilot-to-Autopilot positioning slider, flip switches to turn answers from “think for you” into “think with you”↗13Emotional Attachment: After Users Fall in Love with Your ProductAttachment is real—the Replika 2023 incident proved depth and risk. Grade six user messages with the attachment-signal classifier, open the four-act Replika timeline, then flip three safety valves: identity reminder, vulnerable-topic handoff, impermanence disclosure↗14The Psychology of Paying: Where It Hurts to Pay for a Probabilistic GoodFeel metering anxiety as usage billing makes every follow-up sting, then switch to monthly and watch the same chat’s mood change; four mental-accounting questions show how reframing the same money changes the pain; three quota levers turn free quota from a cost sink into a converter↗15The Psychology of Pricing: Anchors, Decoys, and Decent Price DiscriminationRecreate The Economist's decoy experiment: remove the tier nobody picks and sales flip; flip switches to build your own pricing-page anchors; judge which of five forms of price discrimination are decent and which are career-ending; finally pick the price-hike email that won't get you roasted↗16The Psychology of Feedback: Why Users Don’t Thumbs-DownA thousand unhappy users; only a dozen thumbs-down. The feedback-funnel simulator shows how silence bias eats signal layer by layer; six behaviors read as implicit signals (regenerate, copy, edit); post-thumbs-down experience duel: feedback needs an instant payoff↗17Nine Books to Thicken This ChapterFrom Kahneman, Norman, Cialdini, and Thaler to The Media Equation: nine books unpack nineteen principles every PM needs, each with an AI product application and a lesson to revisit; pick by the problem your product has now, then take a quick principle-matching quiz↗18Finale · Sixteen Effects on One Table, Plus Fourteen Pre-Launch QuestionsFrom perceived performance to silence bias—sixteen psychological effects × engineering levers in full; the right column is all switches you’ve learned; a checkable fourteen-question pre-launch list, plus eleven further-reading picks↗19AI Product Psychology · 40 Soul-Searching QuestionsEach question comes with what they’re assessing, an answer framework, and bonus points: perceived performance / peak-end tradeoffs / trust calibration / dismantling defensiveness / algorithm aversion / label discount / emotional attachment / payment & pricing / silence bias / how to write experience metrics into OKRs↗
