About Mindful Digest

A library for learning to write clearly.

Research, persuasion, and writing belong in the same conversation. We explain how they connect, so you can make a better decision about the words.

Our mission

Understand the work.
Respect the reader.

We help writers, marketers, and curious minds see how research, message, argument, and words fit together. A useful explanation should make your next decision easier.

The library is written and maintained by the Mindful Digest editorial team. We publish when a lesson is ready to be read, and revise it when our understanding improves.

Our editorial policy

Make the reasoning visible.

Lessons connect source material with worked examples and editorial interpretation. Named sources appear in each lesson’s source list. We distinguish research findings from historical principles and practitioner observations, and explain where a claim depends on its original audience or setting.

Constructed examples are labelled as hypothetical in the surrounding text or block. Their sample wording and numbers demonstrate a decision; they are not reported campaign results or customer testimony.

Prefer original sources. Distinguish findings from our interpretation.
Identify hypothetical examples. Never invent results, quotations, or endorsements.
Explain limits and trade-offs. A framework is a tool, not a universal rule.
Show publication and revision dates. Keep corrections visible in the lesson.

Influences, not authorities

Read widely. Question carefully.

Claude Hopkins · Advertising

Scientific Advertising

A historical starting point for thinking about specific claims and testing. Its examples need their original context.

Robert Cialdini · Psychology

Principles of persuasion

A lens for examining how people respond to messages. Read the research before generalizing a principle.

April Dunford · Positioning

Obviously Awesome

A practical approach to understanding alternatives, distinct capabilities, and customer value.

Illustrations, honestly described.

The scenes, still lifes, and teaching objects in lessons illustrate ideas. They do not document a real place, person, or event.

Corrections

Keep the explanation open.

If a claim needs a correction, its lesson should say what changed and why. References appear alongside the work they support. No portrait or practitioner name implies endorsement.

Influences, not endorsements

Learn from the people behind the ideas.

Copywriters and researchers offer useful questions. We read their work, compare the evidence, and explain its limits.
