Understand people.
Design choices with care.

An illustrated field guide by Hendra Saputra, made for people who work in marketing.

Why this atlas exists

Marketing decisions often involve more than a feature list or a price. Attention, memory, context and expectations can change how an offer is understood. This collection makes those ideas easier to inspect through 48 standalone illustrations and concise reading notes.

Start anywhere. Each lesson includes a principle, practical actions, an illustrative example and a question to bring back to your work.

Frameworks, with limits

These are educational explanations, not universal laws or promises of improved performance. Context matters. The examples are illustrative; customer counts, offer terms or evidence templates do not establish facts about a real business. Test comprehension, measure outcomes and protect customer choice.

The illustrations were created with AI assistance and reviewed for conceptual and visual consistency. That review is not independent scientific validation. The written notes are an editorial learning companion.

How People Actually Make Decisions

Explore fast recognition, deliberate comparison and the shortcuts people use when judging offers. Use these lenses to make value understandable while preserving informed customer choice.

Attention and Perception

Examine what people notice and what gets lost among competing messages. Build clearer hierarchy, relevant outreach and a recognizable signal.

Memory, Learning and Habit

Connect distinctive encounters, retrieval cues and useful repeated behaviors. Plan reinforcement without treating memory or habit as an automatic outcome.

Emotion and Motivation

Understand how feelings and current needs can shape perceived value. Connect credible human outcomes with autonomy, capability and belonging.

Social Psychology and Influence

Review the role of other people, credible evidence and shared identity in persuasion. Keep influence grounded in honest claims, voluntary participation and genuine value.

Pricing and Value Perception

Inspect how price presentation, comparison sets and payment experiences shape evaluation. Explain complete costs and test perception without sacrificing clarity or consent.

Behavioral Economics Toolkit

Use behavioral economics to frame fair comparisons and easier decisions. Treat defaults, timing and perceived ownership as hypotheses to validate in context.

Brand Psychology

Build recognizable associations and a coherent brand character. Check cultural context and distinguish a persuasive first impression from evidence of performance.

Digital and Campaign Application

Apply the atlas to landing pages, notifications, email, stories and campaign planning. Keep every promise, action and proof point connected to the customer situation.

Quick Reference

Choose a relevant concept from the marketing task in front of you. Every route finishes with a practical hypothesis, customer understanding and validation.
