Here’s What You Get:

What is Growth.Design – The psychology of UI design

A UX/UI education system + content platform that teaches:

How to design interfaces based on human psychology, cognitive biases, and behavior

Instead of focusing only on visuals, Growth.Design emphasizes:

• how users think

• how they decide

• how interfaces influence behavior

Core Idea: Psychology-driven UI

At its core, Growth.Design teaches:

• UI is not just design

• UI = decision-making system

Meaning:

• every button, color, layout → influences user behavior

They combine:

• UX design

• behavioral psychology

• growth & conversion principles

The “106 Cognitive Biases” Framework

One of their most famous resources is:

A library of 100+ cognitive biases & mental models

These are grouped into 4 stages of user interaction:

1. Information filtering (what users notice)

2. Meaning-making (how they interpret UI)

3. Decision/action (what they click/do)

4. Memory (what they remember later)

This system helps designers:

• predict user behavior

• reduce friction

• increase conversions

Key Psychological Principles (Examples)

1. Recognition > Recall

• Users prefer recognizing options vs remembering

• → Use icons, autofill, suggestions

2. Social Proof

• People follow what others do

• → Reviews, testimonials, user counts

3. Scarcity & Urgency

• Limited time/stock increases action

• → Countdown timers, “only 3 left”

4. Framing Effect

• How info is presented changes decisions

• → “Save $100” vs “Spend $400”

5. Serial Position Effect

• Users remember:

  • first items

  • last items

• → Place key info at top & bottom

UI-Specific Course: “Clear UI”

Their UI-focused training teaches how to apply psychology directly to screens:

Core lessons:

• Copywriting → words drive decisions

• Layout → structure attention

• Emphasis → guide user focus

• Accessibility → reduce cognitive load

• Reward systems → reinforce behavior
