This shows how design goes beyond visuals and becomes its own kind of language. I like how it distinguishes between simple communication and true rhetorical discourse, reminding us that meaning in design only becomes rhetorical when it’s intentional, persuasive, and structured with purpose.

Groupon shows deals with countdown timers—“Deal ends in 3 hours!” to push users to act quickly, leveraging loss aversion.

LinkedIn shows “5 people viewed your profile this week” to encourage users to engage or upgrade, leveraging fear of missing out on networking opportunities.

Duolingo uses streak reminders—“Don’t break your 10-day streak!”—to motivate users to continue lessons, leveraging loss aversion.

E-commerce sites show “Only 2 left in stock” warnings to encourage purchases.

TurboTax presents one question at a time to reduce user overwhelm.

Step-by-step checkout flows (like Shopify’s) reduce effort compared to long, all-in-one forms.

Apple showcases the most expensive iPhone first, making lower-tier models feel like better deals.

E-commerce sites often put “Home” first and “Cart/Checkout” last in navigation menus to leverage memorability.

YouTube’s large, centered play/pause button makes it quick to tap without precision.

Corners of the screen are easy targets, why the Windows “Start” button sits in the bottom-left corner.

Make important buttons large and easy to reach. Place frequently used actions close to expected interaction zones. For example: Mobile keyboards with a large space bar to reduce mistypes.

Spotify challenges confirmation bias by surfacing “Discover Weekly” playlists—introducing users to new artists outside their usual listening habits.

A UX team believes a new checkout design is better. When test results show mixed feedback, they highlight the small improvements but ignore complaints, favoring data that confirms their belief.

Anchoring bias is interesting because it shows how the first number or option we see shapes all our choices after. It makes sense why apps like Tinder or even stores use this, suddenly the "cheaper" option feels like a better deal.

The Cognitive Biases Codex really shows how many ways our thinking can be skewed. I like how Buster Benson broke it into categories—it makes it easier to understand and apply.

Hooked shows how products use psychology and little triggers to keep us hooked. It made me realize UX is not just about design, but also about how much power it has over people’s habits.
