Biases in UX Design — What Every Designer Must Know!
Bias quietly shapes decisions, research, and product outcomes. Knowing it = designing better, fairer, user-centered experiences.

1️⃣ Confirmation Bias —

“We only see what we want to see.”

Designers often favor feedback that supports their ideas and ignore the rest.
Avoid it by:
• Testing early (low-fidelity first)
• Doing discovery research, not validation
• Asking neutral questions
• Staying emotionally neutral in user testing
• Using multiple data sources
• Inviting fresh external perspectives

2️⃣ Negativity Bias —

“One bad experience outweighs ten good ones.”

Users remember bad UX longer than good UX. One frustration can ruin trust.
Avoid it by:
• Reducing friction in key journeys
• Fixing critical usability issues early
• Ensuring consistency & familiarity
• Designing for clarity, not cleverness
• Prioritizing real user expectations

💡 Why it matters?
Being aware of bias =
✔️ Better research
✔️ Better decisions
✔️ Better products
✔️ Happier users

Fitts’ Law —

Why Bigger & Closer Targets Perform Better in UX!

Fitts’ Law explains how fast a user can interact with a UI element.
⏱️ Interaction time depends on:
1️⃣ Distance to the target
2️⃣ Size of the target

So…
✔️ Bigger + Closer = Faster actions
❌ Smaller + Farther = Slower + more errors

🔍 Why It Matters for UX Designers?

Fitts’ Law helps us design experiences that feel:
✔️ Easier
✔️ Faster
✔️ More natural
✔️ Less frustrating

📚 Key Principles

✅ Bigger touch targets = quicker actions
➡️ Apple: 44 × 44 pt
➡️ Google Material: 48 × 48 dp
➡️ WCAG Web: 44 × 44 px

✅ Icon + Text > Icon Alone
➡️ Easier to understand
➡️ Larger clickable area

✅ Keep next actions nearby
➡️ Reduce finger travel
➡️ Avoid top ↔️ bottom jumps

✅ Avoid tiny crowded buttons
➡️ Users may overshoot
➡️ Leads to mistakes

⚠️ Where Designers Go Wrong

❌ Too-small tap areas
❌ Actions too far apart
❌ Important actions placed awkwardly
❌ Forgetting thumb reach on mobile

Example: Some iOS workflows move interaction from top → bottom → top, increasing effort & delay.

📝 Takeaway

Design for:
✔️ Larger tap areas
✔️ Minimal distance between steps
✔️ Logical next-action placement
✔️ Edge advantage when useful

But remember

Fitts’ Law is a guideline, not a rigid rule. Always validate with real user behavior & data

🔥 Coming Next: Hick’s Law — Why Too Many Choices Kill Decisions!
Stay tuned ✨

🎯 Hick’s Law —

Too Many Choices Slow Users Down!

Hick’s Law (Hick–Hyman Law) explains how users make decisions.
It states that:

🧠 The more options users have, the longer they take to decide.
Decision time increases logarithmically, not linearly — meaning complexity grows quickly as choices multiply.

So…
✔️ Fewer / clearer choices → Faster decisions
❌ Too many choices → Confusion, hesitation, drop-offs

🔍 Why It Matters in UX?

Hick’s Law helps designers:
✔️ Reduce cognitive load
✔️ Improve decision speed
✔️ Increase conversion rates
✔️ Create more focused user experiences

Users don’t want to “think hard.” Our job is to guide them.

📚 Real-Life Examples
📺 TV Remote

Old remotes = too many buttons → confusion + slow decisions
Apple TV / Mi Remote = fewer buttons → faster actions
Complexity moves to UI → less cognitive load

🔎 Google Homepage

Just a search bar + actions → only 1 clear decision
No distractions → fast task completion
Perfect example of focus > clutter

🛒 E-commerce Mega Menus

Sometimes you MUST show many options (Walmart, Alibaba etc.).
Hick’s Law doesn’t force reducing options — it guides better organization:

✔️ Group related items
✔️ Use meaningful labels
✔️ Order logically
✔️ Make scanning effortless

⭐️ Pricing & Plan Selection

Too many plans can overwhelm users.
Highlighting one recommended / “Best Value” plan:

✔️ Reduces thinking effort
✔️ Builds confidence
✔️ Speeds decisions

Netflix and SaaS companies do this perfectly.

🧠 How Designers Apply Hick’s Law

1️⃣ Reduce Options

Only show what truly matters.
Less clutter = faster decisions = better conversion.

2️⃣ Break into Steps

Instead of asking everything at once:
Bag → Address → Payment (Myntra checkout example)
Small steps feel effortless.

3️⃣ Show All Options but Guide Users

Use:
✔️ Highlighted options
✔️ Visual emphasis
✔️ Smart defaults

Help users decide faster without removing choice.

📝 Key Takeaways

Hick’s Law helps designers:

✔️ Direct users to what matters most
✔️ Help users reach CTA faster
✔️ Prevent confusion and hesitation
✔️ Improve conversion & usability

But remember

It’s not about “removing choices.”
It’s about presenting them smartly, clearly, and at the right time.

🎯 Miller’s Law —

Why Users Can Remember Only 7±2 Things

Miller’s Law states that:
🧠 The average human can hold only 5–9 items in working memory at once.

This is known as Miller’s Magic Number (7 ± 2) and it plays a huge role in how we design interfaces, content, and flows.

🔍 Why Miller’s Law Matters in UX

Users get overwhelmed easily.
When we show too much information at once, they:
❌ Forget
❌ Get confused
❌ Make mistakes
❌ Abandon tasks

Good UX respects memory limits.

🧠 The Magic of Chunking

Instead of forcing users to remember everything, we group information into chunks.

Example 👇
❌ 8810987563
✅ 8810 – 9875 – 63

Same number. Easier to remember.
This is chunking, and it’s the core idea behind Miller’s Law.

📚 Everyday Examples You Already Know

✔️ Phone numbers (split into groups)
✔️ Credit card numbers (4-4-4-4)
✔️ Social Security / ID numbers
✔️ Presentation slides (5–7 bullets max)
✔️ TV remotes (only essential buttons)

All designed around human memory limits.

🎬 Digital Product Examples
Netflix

• Shows ~6 noscripts per row
• Groups content by categories
• Easy to scan, recall, and decide

Perfect use of 7±2 rule + chunking.

Walmart Mega Menu

• Main categories → subcategories
• Visual grouping + hierarchy
• Reduces complexity of massive content

Large systems made usable with chunks.

Pinterest Explore

• Content grouped by date → category → topic
• Multiple layers of chunking
• Easier browsing & recall

🧩 Where Designers Use Miller’s Law

✔️ Navigation menus (5–7 items)
✔️ Contact lists (limited visible entries)
✔️ Checkout steps (split into stages)
✔️ Supermarket shelves (grouped brands)
✔️ Slides & dashboards (minimal metrics per view)

📝 Key Takeaways for Designers

✔️ Don’t overload memory
✔️ Break content into chunks
✔️ Group related information
✔️ Use hierarchy & spacing
✔️ Show information progressively

⚠️ It’s not about showing exactly 7 items
It’s about reducing cognitive load
